The Kenwood DMX905S is one of five Kenwood models that feature wireless Android Auto, along with a traditional corded Apple CarPlay app. The Kenwood worked well in our testing, but small usability details separated it from our top pick. It has a capacitive display, although pinching-and-zooming didn’t work in Google Maps. The unit’s hard buttons are large enough to press easily, but they don’t have the nice tactile feel of the Pioneer models’.

The Kenwood DMX7704S is very similar to the DMX905S, above, but lacks its wireless Android Auto capability and capacitive display. It has the same relatively large, but tactile-less buttons along the bottom. And we found the menu structure to be more complicated than the Pioneer or the Sony models’.

Because the Kenwood and JVC brands are owned by the same company—JVCKenwood Corporation—the JVC KW-M845BW is similar to the Kenwood DMX905S, above, with wireless Android Auto and only minor design differences. Its 6.8-inch screen is resistive instead of capacitive; it has only one USB port, instead of two; and you can’t change the buttons’ illumination color. It has also only three small, hard buttons, which offer less versatility and are more difficult to use than the Kenwood’s. Most irksome for us, though, is that we had a difficult time wirelessly connecting to Android Auto with our Pixel 2 XL test phone, and switching between two Bluetooth-connected phones wasn’t as seamless as with the Pioneers.

The JVC KW-M730BT, our previous runner-up, and the newer JVC KW-M740BT are almost identical models. When plugged in with a USB cord, both CarPlay and Android Auto worked well. The Pandora and Spotify apps were also flawless when using a Bluetooth connection. Our main gripes are the three tiny hard buttons across the top, which offer less functionality and aren’t as easy to access on the fly as those on the other models we tested. Also, you can’t customize the buttons’ illumination colors.

The new Sony XAV-AX5000 is very similar to our budget pick, except that it has a larger, 7-inch, bezel-less display and smaller, hard buttons across the bottom, rather than the XAV-AX100 model’s volume knob and left-mounted buttons. We had no problems connecting to CarPlay and Android Auto through a USB cord, and the AX5000 provides dual USB ports and satellite radio capability. It could be another good budget choice, but it’s sparse on features, compared with our other picks. It doesn’t come with a GPS antenna; it uses the one in your phone. The display isn’t as customizable. You can’t vary the buttons’ colors. And you can’t connect this model to an iDatalink adapter for use with a car’s steering-wheel controls and other features.

Our former also-great pick, the Alpine iLX-107, was the first replacement car stereo to offer a wireless connection to Apple CarPlay, although it doesn’t include Android Auto. The iLX-107 model’s interface is relatively easy to use, with responsive capacitive volume buttons below the screen. Its screen can be finicky, though, and we often had to hunt and peck to find what we wanted in the menus. The iLX-107 has a 7-inch screen and a host of extra features, such as satellite radio and HD Radio, multiple color choices for the controls, and the capability to pair with up to five smartphones over Bluetooth, but it tends to be more expensive than our top pick.

The Alpine iLX-207 has the same bright, 7-inch display as its cousin, the iLX-107, along with Android Auto, which the iLX-107 lacks. However, it doesn’t have the iLX-107 model’s wireless CarPlay connectivity or its slick capacitive volume buttons. Instead, it has a thick lip across the bottom of the screen that protrudes about half an inch from the display, and houses several large plastic buttons that provide some tactile feedback. The iLX-207 worked fine overall, and includes satellite radio compatibility, HD Radio, selectable illumination colors and wallpaper, and an HDMI input and output. But as with the iLX-107, we often had to hunt and peck to find what we wanted in the menus.

The Sony XAV-AX210 is similar to our budget pick, the Sony XAV-AX100, with a 6.4-inch display and volume knob. But it adds a CD/DVD player, satellite radio capability, variable illumination, and the ability to connect to an iDatalink adapter for use with a car’s steering-wheel controls and other features. An SXM version that includes a SiriusXM tuner as part of a package is currently being sold.

The Pioneer AVIC-8201NEX is very similar to our upgrade pick, but without its wireless capability for CarPlay and Android Auto; you need to plug in with a USB cord. Like the AVIC-W8500NEX, this Pioneer comes with a built-in navigation system, capacitive touchscreen, satellite radio compatibility, HD Radio, and Pioneer’s Dual Zone Entertainment (which gives rear-seat passengers the option to enjoy different content than front-seat passengers).

The Kenwood DNX875S is essentially the same as the DMX905S digital media receiver, above, but with an integrated Garmin navigation system. You can connect to Android Auto either wirelessly or with a USB cord, and to CarPlay with only the cord. But, as with the JVC KW-M845BW, above, we had problems wirelessly connecting to Android Auto with our Pixel 2 XL test phone, and switching between two Bluetooth-paired phones wasn’t as seamless as with the Pioneers. We like the nav system; in our car GPS testing, we’ve found Garmin’s navigation system to be easy to use, with an intuitive interface, reliable and responsive routing, and helpful lane guidance at highway interchanges. As with Pioneer’s Here mapping, Garmin’s traffic data isn’t as comprehensive or accurate as that of Google Maps and Waze, though. The DNX875S is compatible with Kenwood’s DRV-N520 dash cam, and can accept two camera inputs.

Our previous upgrade pick, the Kenwood DNX694S, and the newer Kenwood DNX695S are very similar models. We had no trouble connecting to CarPlay and Android Auto through a USB cord. Both models come with built-in Garmin navigation, a CD/DVD player, HD Radio, satellite radio compatibility, variable color adjustments for customizing the controls’ backlighting, and dual video inputs for connecting multiple cameras. Unlike on the other Kenwoods we tested, the buttons are located on the left side of the screen, where they’re easier for a driver to reach, and the CD/DVD slot is visible above the 6.8-inch display. Both models can connect to the company’s DRV-N520 dash cam, and when a backup camera is connected, the stereo overlays helpful parking-guidance lines onto the camera’s image. According to Kenwood’s Seth Halstead, drivers can also connect other accessories, such as an add-on forward-collision warning system.

A touchscreen or touch screen is the assembly of both an input ("touch panel") and output ("display") device. The touch panel is normally layered on the top of an electronic visual display of an information processing system. The display is often an LCD, AMOLED or OLED display while the system is usually used in a laptop, tablet, or smartphone. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers.zooming to increase the text size.

The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or other such devices (other than a stylus, which is optional for most modern touchscreens).

Touchscreens are common in devices such as game consoles, personal computers, electronic voting machines, and point-of-sale (POS) systems. They can also be attached to computers or, as terminals, to networks. They play a prominent role in the design of digital appliances such as personal digital assistants (PDAs) and some e-readers. Touchscreens are also important in educational settings such as classrooms or on college campuses.

The popularity of smartphones, tablets, and many types of information appliances is driving the demand and acceptance of common touchscreens for portable and functional electronics. Touchscreens are found in the medical field, heavy industry, automated teller machines (ATMs), and kiosks such as museum displays or room automation, where keyboard and mouse systems do not allow a suitably intuitive, rapid, or accurate interaction by the user with the display"s content.

Historically, the touchscreen sensor and its accompanying controller-based firmware have been made available by a wide array of after-market system integrators, and not by display, chip, or motherboard manufacturers. Display manufacturers and chip manufacturers have acknowledged the trend toward acceptance of touchscreens as a user interface component and have begun to integrate touchscreens into the fundamental design of their products.

The prototypeCERNFrank Beck, a British electronics engineer, for the control room of CERN"s accelerator SPS (Super Proton Synchrotron). This was a further development of the self-capacitance screen (right), also developed by Stumpe at CERN

One predecessor of the modern touch screen includes stylus based systems. In 1946, a patent was filed by Philco Company for a stylus designed for sports telecasting which, when placed against an intermediate cathode ray tube display (CRT) would amplify and add to the original signal. Effectively, this was used for temporarily drawing arrows or circles onto a live television broadcast, as described in US 2487641A, Denk, William E, "Electronic pointer for television images", issued 1949-11-08. Later inventions built upon this system to free telewriting styli from their mechanical bindings. By transcribing what a user draws onto a computer, it could be saved for future use. See US 3089918A, Graham, Robert E, "Telewriting apparatus", issued 1963-05-14.

The first version of a touchscreen which operated independently of the light produced from the screen was patented by AT&T Corporation US 3016421A, Harmon, Leon D, "Electrographic transmitter", issued 1962-01-09. This touchscreen utilized a matrix of collimated lights shining orthogonally across the touch surface. When a beam is interrupted by a stylus, the photodetectors which no longer are receiving a signal can be used to determine where the interruption is. Later iterations of matrix based touchscreens built upon this by adding more emitters and detectors to improve resolution, pulsing emitters to improve optical signal to noise ratio, and a nonorthogonal matrix to remove shadow readings when using multi-touch.

The first finger driven touch screen was developed by Eric Johnson, of the Royal Radar Establishment located in Malvern, England, who described his work on capacitive touchscreens in a short article published in 1965Frank Beck and Bent Stumpe, engineers from CERN (European Organization for Nuclear Research), developed a transparent touchscreen in the early 1970s,In the mid-1960s, another precursor of touchscreens, an ultrasonic-curtain-based pointing device in front of a terminal display, had been developed by a team around Rainer Mallebrein[de] at Telefunken Konstanz for an air traffic control system.Einrichtung" ("touch input facility") for the SIG 50 terminal utilizing a conductively coated glass screen in front of the display.

In 1972, a group at the University of Illinois filed for a patent on an optical touchscreenMagnavox Plato IV Student Terminal and thousands were built for this purpose. These touchscreens had a crossed array of 16×16 infrared position sensors, each composed of an LED on one edge of the screen and a matched phototransistor on the other edge, all mounted in front of a monochrome plasma display panel. This arrangement could sense any fingertip-sized opaque object in close proximity to the screen. A similar touchscreen was used on the HP-150 starting in 1983. The HP 150 was one of the world"s earliest commercial touchscreen computers.infrared transmitters and receivers around the bezel of a 9-inch Sony cathode ray tube (CRT).

In 1977, an American company, Elographics – in partnership with Siemens – began work on developing a transparent implementation of an existing opaque touchpad technology, U.S. patent No. 3,911,215, October 7, 1975, which had been developed by Elographics" founder George Samuel Hurst.World"s Fair at Knoxville in 1982.

In 1984, Fujitsu released a touch pad for the Micro 16 to accommodate the complexity of kanji characters, which were stored as tiled graphics.Sega released the Terebi Oekaki, also known as the Sega Graphic Board, for the SG-1000 video game console and SC-3000 home computer. It consisted of a plastic pen and a plastic board with a transparent window where pen presses are detected. It was used primarily with a drawing software application.

Touch-sensitive control-display units (CDUs) were evaluated for commercial aircraft flight decks in the early 1980s. Initial research showed that a touch interface would reduce pilot workload as the crew could then select waypoints, functions and actions, rather than be "head down" typing latitudes, longitudes, and waypoint codes on a keyboard. An effective integration of this technology was aimed at helping flight crews maintain a high level of situational awareness of all major aspects of the vehicle operations including the flight path, the functioning of various aircraft systems, and moment-to-moment human interactions.

In the early 1980s, General Motors tasked its Delco Electronics division with a project aimed at replacing an automobile"s non-essential functions (i.e. other than throttle, transmission, braking, and steering) from mechanical or electro-mechanical systems with solid state alternatives wherever possible. The finished device was dubbed the ECC for "Electronic Control Center", a digital computer and software control system hardwired to various peripheral sensors, servos, solenoids, antenna and a monochrome CRT touchscreen that functioned both as display and sole method of input.stereo, fan, heater and air conditioner controls and displays, and was capable of providing very detailed and specific information about the vehicle"s cumulative and current operating status in real time. The ECC was standard equipment on the 1985–1989 Buick Riviera and later the 1988–1989 Buick Reatta, but was unpopular with consumers—partly due to the technophobia of some traditional Buick customers, but mostly because of costly technical problems suffered by the ECC"s touchscreen which would render climate control or stereo operation impossible.

Multi-touch technology began in 1982, when the University of Toronto"s Input Research Group developed the first human-input multi-touch system, using a frosted-glass panel with a camera placed behind the glass. In 1985, the University of Toronto group, including Bill Buxton, developed a multi-touch tablet that used capacitance rather than bulky camera-based optical sensing systems (see History of multi-touch).

The first commercially available graphical point-of-sale (POS) software was demonstrated on the 16-bit Atari 520ST color computer. It featured a color touchscreen widget-driven interface.COMDEX expo in 1986.

In 1987, Casio launched the Casio PB-1000 pocket computer with a touchscreen consisting of a 4×4 matrix, resulting in 16 touch areas in its small LCD graphic screen.

Touchscreens had a bad reputation of being imprecise until 1988. Most user-interface books would state that touchscreen selections were limited to targets larger than the average finger. At the time, selections were done in such a way that a target was selected as soon as the finger came over it, and the corresponding action was performed immediately. Errors were common, due to parallax or calibration problems, leading to user frustration. "Lift-off strategy"University of Maryland Human–Computer Interaction Lab (HCIL). As users touch the screen, feedback is provided as to what will be selected: users can adjust the position of the finger, and the action takes place only when the finger is lifted off the screen. This allowed the selection of small targets, down to a single pixel on a 640×480 Video Graphics Array (VGA) screen (a standard of that time).

Sears et al. (1990)human–computer interaction of the time, describing gestures such as rotating knobs, adjusting sliders, and swiping the screen to activate a switch (or a U-shaped gesture for a toggle switch). The HCIL team developed and studied small touchscreen keyboards (including a study that showed users could type at 25 wpm on a touchscreen keyboard), aiding their introduction on mobile devices. They also designed and implemented multi-touch gestures such as selecting a range of a line, connecting objects, and a "tap-click" gesture to select while maintaining location with another finger.

In 1990, HCIL demonstrated a touchscreen slider,lock screen patent litigation between Apple and other touchscreen mobile phone vendors (in relation to

An early attempt at a handheld game console with touchscreen controls was Sega"s intended successor to the Game Gear, though the device was ultimately shelved and never released due to the expensive cost of touchscreen technology in the early 1990s.

Touchscreens would not be popularly used for video games until the release of the Nintendo DS in 2004.Apple Watch being released with a force-sensitive display in April 2015.

In 2007, 93% of touchscreens shipped were resistive and only 4% were projected capacitance. In 2013, 3% of touchscreens shipped were resistive and 90% were projected capacitance.

A resistive touchscreen panel comprises several thin layers, the most important of which are two transparent electrically resistive layers facing each other with a thin gap between. The top layer (that which is touched) has a coating on the underside surface; just beneath it is a similar resistive layer on top of its substrate. One layer has conductive connections along its sides, the other along top and bottom. A voltage is applied to one layer and sensed by the other. When an object, such as a fingertip or stylus tip, presses down onto the outer surface, the two layers touch to become connected at that point.voltage dividers, one axis at a time. By rapidly switching between each layer, the position of pressure on the screen can be detected.

Resistive touch is used in restaurants, factories and hospitals due to its high tolerance for liquids and contaminants. A major benefit of resistive-touch technology is its low cost. Additionally, as only sufficient pressure is necessary for the touch to be sensed, they may be used with gloves on, or by using anything rigid as a finger substitute. Disadvantages include the need to press down, and a risk of damage by sharp objects. Resistive touchscreens also suffer from poorer contrast, due to having additional reflections (i.e. glare) from the layers of material placed over the screen.3DS family, and the Wii U GamePad.

Surface acoustic wave (SAW) technology uses ultrasonic waves that pass over the touchscreen panel. When the panel is touched, a portion of the wave is absorbed. The change in ultrasonic waves is processed by the controller to determine the position of the touch event. Surface acoustic wave touchscreen panels can be damaged by outside elements. Contaminants on the surface can also interfere with the functionality of the touchscreen.

The Casio TC500 Capacitive touch sensor watch from 1983, with angled light exposing the touch sensor pads and traces etched onto the top watch glass surface.

A capacitive touchscreen panel consists of an insulator, such as glass, coated with a transparent conductor, such as indium tin oxide (ITO).electrostatic field, measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location is then sent to the controller for processing. Touchscreens that use silver instead of ITO exist, as ITO causes several environmental problems due to the use of indium.complementary metal-oxide-semiconductor (CMOS) application-specific integrated circuit (ASIC) chip, which in turn usually sends the signals to a CMOS digital signal processor (DSP) for processing.

Unlike a resistive touchscreen, some capacitive touchscreens cannot be used to detect a finger through electrically insulating material, such as gloves. This disadvantage especially affects usability in consumer electronics, such as touch tablet PCs and capacitive smartphones in cold weather when people may be wearing gloves. It can be overcome with a special capacitive stylus, or a special-application glove with an embroidered patch of conductive thread allowing electrical contact with the user"s fingertip.

A low-quality switching-mode power supply unit with an accordingly unstable, noisy voltage may temporarily interfere with the precision, accuracy and sensitivity of capacitive touch screens.

Some capacitive display manufacturers continue to develop thinner and more accurate touchscreens. Those for mobile devices are now being produced with "in-cell" technology, such as in Samsung"s Super AMOLED screens, that eliminates a layer by building the capacitors inside the display itself. This type of touchscreen reduces the visible distance between the user"s finger and what the user is touching on the screen, reducing the thickness and weight of the display, which is desirable in smartphones.

In this basic technology, only one side of the insulator is coated with a conductive layer. A small voltage is applied to the layer, resulting in a uniform electrostatic field. When a conductor, such as a human finger, touches the uncoated surface, a capacitor is dynamically formed. The sensor"s controller can determine the location of the touch indirectly from the change in the capacitance as measured from the four corners of the panel. As it has no moving parts, it is moderately durable but has limited resolution, is prone to false signals from parasitic capacitive coupling, and needs calibration during manufacture. It is therefore most often used in simple applications such as industrial controls and kiosks.

This diagram shows how eight inputs to a lattice touchscreen or keypad creates 28 unique intersections, as opposed to 16 intersections created using a standard x/y multiplexed touchscreen .

Projected capacitive touch (PCT; also PCAP) technology is a variant of capacitive touch technology but where sensitivity to touch, accuracy, resolution and speed of touch have been greatly improved by the use of a simple form of

Some modern PCT touch screens are composed of thousands of discrete keys,etching a single conductive layer to form a grid pattern of electrodes, by etching two separate, perpendicular layers of conductive material with parallel lines or tracks to form a grid, or by forming an x/y grid of fine, insulation coated wires in a single layer . The number of fingers that can be detected simultaneously is determined by the number of cross-over points (x * y) . However, the number of cross-over points can be almost doubled by using a diagonal lattice layout, where, instead of x elements only ever crossing y elements, each conductive element crosses every other element .

In some designs, voltage applied to this grid creates a uniform electrostatic field, which can be measured. When a conductive object, such as a finger, comes into contact with a PCT panel, it distorts the local electrostatic field at that point. This is measurable as a change in capacitance. If a finger bridges the gap between two of the "tracks", the charge field is further interrupted and detected by the controller. The capacitance can be changed and measured at every individual point on the grid. This system is able to accurately track touches.

Unlike traditional capacitive touch technology, it is possible for a PCT system to sense a passive stylus or gloved finger. However, moisture on the surface of the panel, high humidity, or collected dust can interfere with performance.

These environmental factors, however, are not a problem with "fine wire" based touchscreens due to the fact that wire based touchscreens have a much lower "parasitic" capacitance, and there is greater distance between neighbouring conductors.

This is a common PCT approach, which makes use of the fact that most conductive objects are able to hold a charge if they are very close together. In mutual capacitive sensors, a capacitor is inherently formed by the row trace and column trace at each intersection of the grid. A 16×14 array, for example, would have 224 independent capacitors. A voltage is applied to the rows or columns. Bringing a finger or conductive stylus close to the surface of the sensor changes the local electrostatic field, which in turn reduces the mutual capacitance. The capacitance change at every individual point on the grid can be measured to accurately determine the touch location by measuring the voltage in the other axis. Mutual capacitance allows multi-touch operation where multiple fingers, palms or styli can be accurately tracked at the same time.

Self-capacitive touch screen layers are used on mobile phones such as the Sony Xperia Sola,Samsung Galaxy S4, Galaxy Note 3, Galaxy S5, and Galaxy Alpha.

Self capacitance is far more sensitive than mutual capacitance and is mainly used for single touch, simple gesturing and proximity sensing where the finger does not even have to touch the glass surface.

Capacitive touchscreens do not necessarily need to be operated by a finger, but until recently the special styli required could be quite expensive to purchase. The cost of this technology has fallen greatly in recent years and capacitive styli are now widely available for a nominal charge, and often given away free with mobile accessories. These consist of an electrically conductive shaft with a soft conductive rubber tip, thereby resistively connecting the fingers to the tip of the stylus.

Infrared sensors mounted around the display watch for a user"s touchscreen input on this PLATO V terminal in 1981. The monochromatic plasma display"s characteristic orange glow is illustrated.

An infrared touchscreen uses an array of X-Y infrared LED and photodetector pairs around the edges of the screen to detect a disruption in the pattern of LED beams. These LED beams cross each other in vertical and horizontal patterns. This helps the sensors pick up the exact location of the touch. A major benefit of such a system is that it can detect essentially any opaque object including a finger, gloved finger, stylus or pen. It is generally used in outdoor applications and POS systems that cannot rely on a conductor (such as a bare finger) to activate the touchscreen. Unlike capacitive touchscreens, infrared touchscreens do not require any patterning on the glass which increases durability and optical clarity of the overall system. Infrared touchscreens are sensitive to dirt and dust that can interfere with the infrared beams, and suffer from parallax in curved surfaces and accidental press when the user hovers a finger over the screen while searching for the item to be selected.

A translucent acrylic sheet is used as a rear-projection screen to display information. The edges of the acrylic sheet are illuminated by infrared LEDs, and infrared cameras are focused on the back of the sheet. Objects placed on the sheet are detectable by the cameras. When the sheet is touched by the user, frustrated total internal reflection results in leakage of infrared light which peaks at the points of maximum pressure, indicating the user"s touch location. Microsoft"s PixelSense tablets use this technology.

Optical touchscreens are a relatively modern development in touchscreen technology, in which two or more image sensors (such as CMOS sensors) are placed around the edges (mostly the corners) of the screen. Infrared backlights are placed in the sensor"s field of view on the opposite side of the screen. A touch blocks some lights from the sensors, and the location and size of the touching object can be calculated (see visual hull). This technology is growing in popularity due to its scalability, versatility, and affordability for larger touchscreens.

Introduced in 2002 by 3M, this system detects a touch by using sensors to measure the piezoelectricity in the glass. Complex algorithms interpret this information and provide the actual location of the touch.

The key to this technology is that a touch at any one position on the surface generates a sound wave in the substrate which then produces a unique combined signal as measured by three or more tiny transducers attached to the edges of the touchscreen. The digitized signal is compared to a list corresponding to every position on the surface, determining the touch location. A moving touch is tracked by rapid repetition of this process. Extraneous and ambient sounds are ignored since they do not match any stored sound profile. The technology differs from other sound-based technologies by using a simple look-up method rather than expensive signal-processing hardware. As with the dispersive signal technology system, a motionless finger cannot be detected after the initial touch. However, for the same reason, the touch recognition is not disrupted by any resting objects. The technology was created by SoundTouch Ltd in the early 2000s, as described by the patent family EP1852772, and introduced to the market by Tyco International"s Elo division in 2006 as Acoustic Pulse Recognition.

There are several principal ways to build a touchscreen. The key goals are to recognize one or more fingers touching a display, to interpret the command that this represents, and to communicate the command to the appropriate application.

Dispersive-signal technology measures the piezoelectric effect—the voltage generated when mechanical force is applied to a material—that occurs chemically when a strengthened glass substrate is touched.

There are two infrared-based approaches. In one, an array of sensors detects a finger touching or almost touching the display, thereby interrupting infrared light beams projected over the screen. In the other, bottom-mounted infrared cameras record heat from screen touches.

The development of multi-touch screens facilitated the tracking of more than one finger on the screen; thus, operations that require more than one finger are possible. These devices also allow multiple users to interact with the touchscreen simultaneously.

With the growing use of touchscreens, the cost of touchscreen technology is routinely absorbed into the products that incorporate it and is nearly eliminated. Touchscreen technology has demonstrated reliability and is found in airplanes, automobiles, gaming consoles, machine control systems, appliances, and handheld display devices including cellphones; the touchscreen market for mobile devices was projected to produce US$5 billion by 2009.

The ability to accurately point on the screen itself is also advancing with the emerging graphics tablet-screen hybrids. Polyvinylidene fluoride (PVDF) plays a major role in this innovation due its high piezoelectric properties, which allow the tablet to sense pressure, making such things as digital painting behave more like paper and pencil.

TapSense, announced in October 2011, allows touchscreens to distinguish what part of the hand was used for input, such as the fingertip, knuckle and fingernail. This could be used in a variety of ways, for example, to copy and paste, to capitalize letters, to activate different drawing modes, etc.

For touchscreens to be effective input devices, users must be able to accurately select targets and avoid accidental selection of adjacent targets. The design of touchscreen interfaces should reflect technical capabilities of the system, ergonomics, cognitive psychology and human physiology.

Guidelines for touchscreen designs were first developed in the 2000s, based on early research and actual use of older systems, typically using infrared grids—which were highly dependent on the size of the user"s fingers. These guidelines are less relevant for the bulk of modern touch devices which use capacitive or resistive touch technology.

Much more important is the accuracy humans have in selecting targets with their finger or a pen stylus. The accuracy of user selection varies by position on the screen: users are most accurate at the center, less so at the left and right edges, and least accurate at the top edge and especially the bottom edge. The R95 accuracy (required radius for 95% target accuracy) varies from 7 mm (0.28 in) in the center to 12 mm (0.47 in) in the lower corners.

This user inaccuracy is a result of parallax, visual acuity and the speed of the feedback loop between the eyes and fingers. The precision of the human finger alone is much, much higher than this, so when assistive technologies are provided—such as on-screen magnifiers—users can move their finger (once in contact with the screen) with precision as small as 0.1 mm (0.004 in).

Users of handheld and portable touchscreen devices hold them in a variety of ways, and routinely change their method of holding and selection to suit the position and type of input. There are four basic types of handheld interaction:

Touchscreens are often used with haptic response systems. A common example of this technology is the vibratory feedback provided when a button on the touchscreen is tapped. Haptics are used to improve the user"s experience with touchscreens by providing simulated tactile feedback, and can be designed to react immediately, partly countering on-screen response latency. Research from the University of Glasgow (Brewster, Chohan, and Brown, 2007; and more recently Hogan) demonstrates that touchscreen users reduce input errors (by 20%), increase input speed (by 20%), and lower their cognitive load (by 40%) when touchscreens are combined with haptics or tactile feedback. On top of this, a study conducted in 2013 by Boston College explored the effects that touchscreens haptic stimulation had on triggering psychological ownership of a product. Their research concluded that a touchscreens ability to incorporate high amounts of haptic involvement resulted in customers feeling more endowment to the products they were designing or buying. The study also reported that consumers using a touchscreen were willing to accept a higher price point for the items they were purchasing.

Unsupported touchscreens are still fairly common in applications such as ATMs and data kiosks, but are not an issue as the typical user only engages for brief and widely spaced periods.

Touchscreens can suffer from the problem of fingerprints on the display. This can be mitigated by the use of materials with optical coatings designed to reduce the visible effects of fingerprint oils. Most modern smartphones have oleophobic coatings, which lessen the amount of oil residue. Another option is to install a matte-finish anti-glare screen protector, which creates a slightly roughened surface that does not easily retain smudges.

Touchscreens do not work most of the time when the user wears gloves. The thickness of the glove and the material they are made of play a significant role on that and the ability of a touchscreen to pick up a touch.

ar stereos with screens the size of tablets have arrived at Crutchfield, and that’s good news for more car owners than ever. If you’ve been craving a big screen stereo for easy source selection while driving, car audio legends like Alpine, Pioneer, Sony, Kenwood, and more offer some seriously sleek solutions.

There’s a lot to be excited about when it comes to car stereos with oversized touchscreen displays. Striking resolution and responsive control make these stereos a joy to use. Plus, built-in essentials for smartphone integration and voice control like Apple CarPlay® and Android Auto™ look great on a big screen. But the most satisfying development here is that most of these car stereos fit dash openings that previously couldn’t accommodate touchscreen receivers. Use our vehicle fit tool to explore your options.

Because the touchscreen display of these special stereos "floats" in front of your dash, it’s important to evaluate the layout of your air vents and any other controls around where your radio lives. No dash layout is the same. So, car stereos with oversized screens, like the Sony shown below, prioritize adjustability.

Jensen"s CAR110X digital media receiver offers nice compatibility with your smartphone for the most affordable price tag in this category. You"ll get Apple CarPlay and Android Auto compatibility, USB inputs for phone charging, and 4-volt preamp outputs to incorporate an aftermarket amp and build a solid system — all with a 10.1" touchscreen display.

I"ve always enjoyed Sony"s approach to digital multimedia receivers. Their streamlined menus and layout make selecting sources and adjusting settings downright breezy. Their XAV-AX8100 brings that same thinking to a 8.95" screen. With 20 watts RMS of built-in power, 5-volt preamp outputs for system-building, awesome smartphone integration, and a 3-year warranty, Sony"s entry into the oversized category offers a whole lot of bang for your buck.

In the case of their DMH-WT8600NEX, the 10.1" capacitive HD touchscreen display looks gorgeous. And as you"d expect, Pioneer builds in excellent audio controls and loads of features, including Amazon Alexa compatibility and inputs for two cameras. I previewed Pioneer"s other stereos in this series and was impressed by the sturdiness and striking beauty of their displays as well.

And if that"s not big enough, Alpine equipped their newest Halo receiver — the stunning ILX-F411 — with an 11" screen! The ILX-F411 lets you customize your display, but you"ll lose HD Radio® compatibility, the ability to add Alpine"s Truck Accessory Controller, and certain interface controls only available on the ILX-F309.

No surprise that JVC"s KW-Z1000W digital multimedia receiver with a 10.1" screen is a solid entry in the category. If you"re adding an aftermarket amplifier, speakers, and sub, you"ll want to give this one serious consideration. 5-volt preamp outputs for a powerfully clean audio signal, a 13-band EQ, time alignment, and K2 sound-enhancement technology let you make sound-tweaking a priority.

Kenwood"s Excelon Reference MXD1057XR digital multimedia receiver is the real deal. Upgrade to a 10.1" floating display with built-in HD Radio, Apple CarPlay, Android Auto, support of high-res audio, and the confidence that comes with a 2-year warranty. Kenwood gives you the tools to customize your homescreen with essential sources and tools. Plus, you get a good ol" fashioned volume knob!

If you need help determining if a floating screen car stereo is right for you, give our Advisors a call. You can also confirm fit for any of the above stereos by using our vehicle selector.

Why put a large, touchscreen stereo in your dash? Fantastic looks are a great starting point, but there’s so much more you can get from a big screen stereo. You can see all the information you need at a quick glance, letting you get your eyes back on the road faster. You’ll also have expansion options like smartphone integration, navigation, and additional cameras available to you.

But, it’s all about the screen real estate and what it can show you. The large display and touchscreen controls make it easier to do anything on the stereo. Let’s talk about some ways to get the most out of a touchscreen receiver.

With a large screen acting as your receiver"s display, it"s a whole lot easier to read than the single-line displays of traditional car stereos. You can quickly see what’s playing, who’s calling, and where you’re going.

Many of these receivers offer the functionality of Apple CarPlay™ and Android Auto™, which emulate your smartphone experience right on the receiver’s touchscreen display – great for keeping your phone out of your hand.

A rear-view or backup camera can help make your touchscreen stereo a valuable tool for staying safe while backing up and to help avoid accidents. Its wide field of view offers a whole lot more of what’s behind you than using your mirror, including areas that your vehicle"s body blocks from view. Many new stereos also offer multiple camera inputs, so you can incorporate factory cameras or add aftermarket cameras for areas like your side view – all viewable on the touchscreen display.

Are we there yet? Touchscreen stereos with built-in GPS navigation offer incredible convenience and assistance. But if you don"t want to spend the extra money for built-in navigation and future map updates, look for a touchscreen stereo that has Apple CarPlay or Android Auto. Both of these options get your smartphone involved to use navigation apps, such as Waze and Google Maps. They appear beautifully on the stereo"s large display.

In addition to the music and caller info that you can see on the display, many touchscreen receivers let you customize the background and layout. So not only can you make a personal statement on the look in your dash, but you can organize the functions that you use the most.

We’ve heard comments from customers who worry that touchscreen receivers are a distracting hindrance rather than a help. And hey, we get it; we’re on the road, too. Here are some keys to using them safely (and maybe some things you didn’t know about): Adjust your screen settings before you drive. In the excitement of installing and turning on a new receiver (which we completely appreciate), some people will hit the road and try to adjust the settings on the fly. Simply put, don’t. In fact, most touchscreen stereos won"t let you access the menus while the car is moving. Before you put your vehicle in gear: Set the display the way you want it. That includes the contrast, backlighting, dimming, and variable color controls. Sure, you can reset them later if you need to…while you’re parked.

There’s usually a one or two button sequence that can disable the display completely and quickly. The audio still works, so your music will keep playing, and navigation apps can still tell you where to go. And it"ll automatically turn back on when you touch it.

Get used to the controls. Many folks have mentioned that there are no “muscle memory” buttons and knobs on touchscreen receivers that can be reached without looking, which is a great point. But many models actually do have handy knobs or easy-to-find toggle buttons for volume control or other important adjustments. Some of the knobs are multi-functional for a variety of settings, not just the volume.

JVC incorporates a feature called "Gesture Control" for simple, quick controls for less distraction. Some receiver makers provide for some simple “no-look” controls on the display itself. For example, JVC’s "Gesture Control" lets you swipe the touchscreen display to the right for track forward, left for track back, and a circular motion to adjust the volume – all with your eyes still on the road.

Example: I programmed a “Pause” on my steering wheel controls to simply stop the music without reaching for the screen. It’s great for keeping my eyes on narrow drive-thru lanes.

Add a compatible remote control. Many touchscreen receivers work with a trusty handheld remote control. Sometimes it"s included, sometimes it"s optional. For example, once he learned the remote button layout, my Dad loved using the remote to control his stereo without looking at or touching the stereo. This from a person who asked “Why do I need a remote control for a car stereo?”

Know the driving laws in your state. It’s a good idea to reach out to your local governments to see what the rules are governing smartphone and touchscreen display use. Read our article about phone safety in the car.

Regardless of which one you choose, the elegance of a touchscreen receiver makes them fun to use and incredibly handy. Use our handy vehicle selector tool to see which stereos will fit your vehicle. And our Advisors are available by phone or chat to help you choose the right touchscreen receiver for you.

You see, I’ve beeninstalling car audio systems for over20 years, and I love every freaking minute of it. This is why I’m sharing with you the best there is nowadays. I’m ranking these flip-out radio units according to their features, sound performance, ease of installation, and coolness. However, with any of the ones introduced below, you will come out a winner. You will not only have the latest tech for safe driving but will also have a great-sounding car.

The biggie for me with these stereos is the LCD screen. Indeed, depending on your car, you won’t get to watch any DVDs during the day as the screen is washed out by the sunlight (this is why it’s the best single din dvd player). Plus, the resolution is pretty weak as well.

Just look at that beautiful screen… We’re in a new era! There’s no reason to stick to crappy low-resolution stereos. By getting this Eincar stereo, you can finally be proud of your system.

The reason why the pioneer avh 3500nex has earned the best single DIN flip out stereo award was because of numerous features. First of all, it’s an inexpensive way to get Apple Carplay. The connection is through the USB cord, and you still have hands-free control. It works with Android Auto as well.

For all those who are safety conscious, there’s a video input. If you value safe and fast parking, you will mount a backup camera(connected via the camera input). Last but not least, I want to mention that my kids love whenever the screen pops out, and it’s tucked away automatically.

The Pioneer AVH-3500NEX is my top choice for single DIN head units. It has everything you need (Radio, CD/DVD, 7″, backup camera, etc). Plus it is the latest one in the Pioneer family.

Some other flip out screens are overcompensating. I’m a conformist person, and I love products that are simple. Flashy in your face tech never appealed to me.

You can install rear screens, so they are entertained. Don’t forget to drive responsibly. If you have already seen the DVD a few times, close it down.

This car stereo is a single DIN head unit. The LCD screen flips out when you hit the power button. The price is unbeatable. You get so many great features tucked into this small device.

During the summer I prefer cold air instead of entertainment. But now we can enjoy both. Besides the usual smarthpone apps you can try Appradio mode. It’s clunky and it’s not well designed. If you check the reviews they are all one star for Appradio mode.

It can’t be customized. Yet certain Android-based flip out stereos can be fully customized. With the camera input you can mount a backup camera. It also has camera output. They did a great job wit hthis single din fold out screen stereo.

Also known as an articulating screen, a flip out screen is an unfixed LCD which can be repositioned with the aid of a pivot or hinge. The flip-out screen is also known as a flip screen, articulated screen, hinged screen, flip screen, adjustable screen, articulating screen or pop out touch screen.

People like flip-out screen head units for a variety of reasons, with the most popular of them being because of their space economy. A flip-out screen head unit is a system that fits, slides out of the dash, and hides when you want it to. It isn’t difficult to see why a lot of drivers are opting for it – to maximize space.

In order to ensure that our list is an all-encompassing one that will be able to help a variety of buyers, several elements such as designs, types, and most especially, price points, are considered for the purpose of this guide. We are confident that you’ll be able to find a great flip out radio that fits in your budget in this article.

When you’re looking to determine the performance and functionality of a touchscreen head unit, the first thing you look at is its power rating. The maximum power refers to the max. amount of watts that can be generated by the device within a short period, while the RMS power is the power generated continuously. However, you shouldn’t allow yourself to be deceived by the incessant emphasis laid on maximum power by manufacturers, as the most important number is actually the RMS power output.

While Bluetooth technology makes things very easy nowadays, that doesn’t mean you can’t have a device that will require a USB connectivity (usb inputs) or an auxiliary input. Some flip out screen car stereos also provide video/audio outputs so that you will be able to connect rear seat video screens or portable music players. If you are using an external amplifier or/and subwoofers, make sure your new head unit is capable of accommodating those accessories also. Usually the USB inputs are located on the back with most single din units. To get the USB input running you will have to run a wire from the to the front. What about shock protection? This is important you don’t want to fry your brand new car stereo by mistake if it doesn’t have shock protection.

You also need to consider the design and aesthetics of the flip out touchscreen head unit you’re looking at. We recommend you to opt for a design that complements the interior of your car. One thing you must keep in mind is that the most expensive models come with an advanced display like LED display (lcd touchscreen) and customized lighting. There are many affordable flip out touchscreen car stereos with excellent designs. The most important thing is the user inter face. Let’s face it if the user interface is hard to understand it will be a pain using it. Higher the price tag better the build quality.

Android Auto and Apple CarPlay are systems that enable the stereo system of your car to content from your smartphone. These systems enable drivers to use their phone’s basic features like calling, navigating, and listening to music. Both systems are quite similar in many ways, except for a couple of ways, which won’t make a lot of difference for a lot of drivers.

With any car stereo the interface of the Android Auto takes some learning and getting used to, the interface of the CarPlay is a lot simpler and looks like what you see on iPhones. Both systems come with easy to use, simple, and attractive designs, so the final decision is up to you and winds down to which one you prefer. Another difference you might want to keep in mind is that CarPlay will use Apple Maps for navigating, while Android Auto uses Google Maps. Most of these stereos are connected through USB input by a cord aka usb connection. Since these are top of the line products you get easy access to phone features. Also you can use other smartphone apps. Also you have a ton of connectivity options.

Also known as single DIN and double DIN, 1 DIN and 2 DIN are the two primary radio sizes used on modern cars. While the two systems were almost equally popular in past years, it seems 2 DIN car stereo has taken the top spot outrightly in recent years. The reasons aren’t farfetched, are they? Double DINs are usually bigger than their 1 DIN counterparts, they often feature superior interface, more functions, and more buttons. Some even come with touchscreen capabilities and some fancy perks like trackers and GPS locators.

However, in order to listen to good music in your car, you need an equally good car stereo system. So, if the available space in your car is limited, you might want to look away from the popular 2 DIN stereos and consider buying a single din flip-out head unit. Sleek, compact, beautiful, and affordable, there is nothing stopping you from enjoying good music once you install one of the radio units in our review in your car.

Yes, hands-free calling works if the car stereo has Bluetooth connectivity. All the stereos mentioned above have the hands-free calling feature. Now if you want steering wheel controls that’s another issue. Phone calls can be easily made if you use Android Auto or Apple Carplay.

Yes, the pioneer avh 3300nex is one of the best pioneer flip out radio. However, there is a new updated version of it the pioneer avh 3500nex which one the best pioneer single din flip out car stereo award.

Yes, Pioneer is the best brand. Flip out radios from pioneer are great. If you are looking for the best of the best flip up car stereos from Pioneer are the best.

You can always rely on the brand Pioneer because they produce high-quality car stereos. They have LCD touchscreen displays that are easy to use, and they’re more affordable than other models.

The screen size of car stereos is different, ranging from 3.2 inches to 8.8 inches. Overall the screen size of car stereos is getting bigger. It’s convenient to have a large display on your dashboard so that you can easily read what you’re listening to!

Most of us enjoy music while we"re driving, but often the radio doesn"t play the tunes that get you rocking. While CDs are a good choice, they scratch easily and you have to swap them often. So what can you do if you want to play music from your phone in the car? How do you connect your smartphone to your car radio?

Although we"re discussing the use of a smartphone while driving, it is important to understand just what this means. While you"re not making calls or texting, the device is still running. As such, taking your hand off the wheel and eyes off the road to change track, find a new radio station, switch audiobook chapters, or load a new podcast is dangerous. It"s even illegal in many areas, just like taking a call or texting.

On your Android device, open Settings > Device Connection > Bluetooth and set it to On. (You can also find your way here by pulling down the notification shade and long-pressing the Bluetooth button.) Wait for the screen to update and display your car audio system, then select it to pair.

Once done, your phone should automatically pair with the car in the future. On long journeys (especially if you"re also using Google Maps or some other GPS app), you should keep your phone charged while driving.

Android Auto is a Google app that allows you to use some of your phone"s features while on the go. To use Android Auto you will need an Android phone with Android 6 Marshmallow or newer, a compatible car stereo, and a high-quality USB cable to connect your phone to your car.

Google also has a wireless version of the Android Auto app, aptly named Android Auto Wireless. To use Android Auto Wireless to connect your Android phone to your car you will need an Android device with Android 11 or newer. Check out how to use Android
