Virtual touch screen

For instance, using a display and a rear projector system a person could create images that look three-dimensional and appear to float in midair.

[13] Virtual touch screen technology can also be applied to turn non-touch displays into interactive, touch-capable surfaces using a Kinect sensor in combination with a projector.

[14] This type of application allows virtual touch technology to enhance personal display usage as well as better communication and presentation of data to be used in education or business settings.

[15] Additionally, Microsoft's Kinect sensor has also employed the use of virtual touch screen technology to help stroke patients recover and improve motor function in their limbs through a game-like system involving interpretation of gestures combined with adjustable difficulty levels based on the user's performance.

Incorporating sufficient haptic feedback to virtual touch screen interactions is an active area of research.
