In newer, modern cars are increasingly being designed as a multi-function display screen. New technologies offer here even an electronically generated, tactile perceptibility.

In home systems, touch screens are not very common, only in the range of PDAs, tablet PCs, smart phones and game consoles at the Nintendo DS will be in greater use. Here to avoid on the small screen annoying fingerprints used input pins (also: Stylus) but are not ergonomic and quite often lead to greater use of the touch screen to scratch. The problem can be solved so far only with a very soft stylus or attaching a protective film.

A touch screen does not necessarily have to be mounted in front of a display, also use them as a replacement keypad. To this end, behind the touch screen (at the point on the normally the computer monitor sits) is applied a printed (polyester) film. There are different approaches to solve completely touch screen monitors from physical to make projections of user interfaces and interactive. Example of this is now re-set "Virtual Touch" by Siemens, or various systems of the Fraunhofer Institute.
