Just need a Surface touch driver or firmware? During troubleshooting, it may be determined that your Surface must be reset or replaced. Depending on your issue, you may not be able to perform these steps.

If your touchscreen does not work after you do this, go on to Solution 2. Having issues getting updates? Want to run your Surface through diagnostics?

See Download drivers and firmware for Surface. For example, if touch does not work in UEFI, your device likely has experienced a hardware failure and needs servicing.

Follow these steps to boot to UEFI and test touch functionality:. Do not manually recalibrate your touch settings. Surface devices come from the factory already calibrated and optimized for pen and touch input to ensure the best possible operation.

At this point, you must verify that the Surface device is not the issue. Use the following table to learn which reset option is right for your situation.

Make sure you install any available updates for your Surface after you do a reset. To find out how, see Install Surface and Windows updates.

Still having the issue? Go to Device service and repair to start a service order for your Surface. Want to leave us feedback about your Surface?

Show all. Touch doesn't respond on part or all of the screen. The technology was created by SoundTouch Ltd in the early s, as described by the patent family EP, and introduced to the market by Tyco International 's Elo division in as Acoustic Pulse Recognition.

The technology usually retains accuracy with scratches and dust on the screen. The technology is also well suited to displays that are physically larger.

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.

In the resistive approach, which used to be the most popular technique, there are typically four layers:. When a user touches the surface, the system records the change in the electric current that flows through the display.

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. This means that there are nearly twice as many cross-over points for a fixed number of terminal connections and no 'bussed' connections around the edges of the touchscreen.

In each case, the system determines the intended command based on the controls showing on the screen at the time and the location of the touch.

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.

The ability to accurately point on the screen itself is also advancing with the emerging graphics tablet-screen hybrids.

Polyvinylidene fluoride PVFD 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 , 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.

A real practical integration between television-images and the functions of a normal modern PC could be an innovation in the near future: for example "all-live-information" on the internet about a film or the actors on video, a list of other music during a normal video clip of a song or news about a person.

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 s, 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 devices which use capacitive or resistive touch technology.

From the mids, makers of operating systems for smartphones have promulgated standards, but these vary between manufacturers, and allow for significant variation in size based on technology changes, so are unsuitable from a human factors perspective.

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.

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.

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:. Use rates vary widely. In addition, devices are often placed on surfaces desks or tables and tablets especially are used in stands.

The user may point, select or gesture in these cases with their finger or thumb, and vary use of these methods. 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.

On top of this, a study conducted in 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. Touchscreen technology has become integrated into many aspects of customer service industry in the 21st century.

Chain restaurants such as Taco Bell, [81] Panera Bread, and McDonald's offer touchscreens as an option when customers are ordering items off the menu.

Customers sit down to a table embedded with touchscreens and order off an extensive menu. Once the order is placed it is sent electronically to the kitchen.

Extended use of gestural interfaces without the ability of the user to rest their arm is referred to as "gorilla arm". Certain early pen-based interfaces required the operator to work in this position for much of the workday.

This phenomenon is often cited as an example of movements to be minimized by proper ergonomic design. 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. From Wikipedia, the free encyclopedia. For other uses, see Touch Sensitive.

The way you use your finger on a touch screen is very similar to how you use a computer mouse on a desktop computer. Not only is it capable of accepting input, but it also displays the output from the computer.

A computer mouse and touch screen have many similarities. Many of them are mentioned in the how do you use the touch screen section above.

One of the most significant differences between a mouse and a touch screen is the ability to hover. Almost all touch screens can only detect input when your finger is in direct contact with the screen.

However, a computer mouse uses a cursor that allows the user to view information by moving the pointer over an object, but not clicking on it.

For example, this link to Computer Hope shows the text "Visit the Computer Hope Page" when hovered over using a computer mouse.

However, a user with a touch screen cannot see this text because if they place their finger on the link, it opens the link.

Some web pages and apps may simulate the hover feature by making the first tap do the hover feature, and the second tap open the link or app.

Also, some Apple devices use Force Touch , offers features similar to hovering. Today, the touch screen is one of the most popular types of input devices.

Below are some places and examples of where touch screens may be used. Below are the reasons a manufacturer may decide to use a touch screen, instead of another input method, such as physical buttons.

Not all touch screens are the same. Different technologies can be utilized to allow a user to interact with a screen.

Some technologies may work with only your finger, and other technologies may allow other tools, like a stylus.

Below is a brief description of each of these technologies. A capacitive touch screen is coated with a special material that stores an electrical charge that is monitored by circuits at each corner of the screen.

When you touch a capacitive touch screen, a small amount of the electrical charge is drawn from the point of contact to indicate where you touched the screen.

To use a capacitive screen, you must use your bare finger or a specially designed capacitive stylus.
