In computing, hardware overlay, a type of video overlay, provides a method of rendering an image to a display screen with a dedicated memory buffer inside computer video hardware. The technique aims to improve the display of a fast-moving video image — such as a computer game , a DVD , or the signal from a TV card .
A touchscreen (or touch screen) is a type of display that can detect touch input from a user. It consists of both an input device (a touch panel) and an output device (a visual display). The touch panel is typically layered on the top of the electronic visual display of a device.

In the old technology, the computer's "vision" was created by a near-infrared, 850-nanometer-wavelength LED light source aimed at the surface. When an object touched the tabletop, the light was reflected to multiple infrared cameras with a net resolution of 1024×768, allowing it to sense, and react to items touching the tabletop.
In computing, multi-touch is technology which enables a touchpad or touchscreen to recognize more than one [7] [8] or more than two [9] points of contact with the surface. Apple popularized the term "multi-touch" in 2007 with which it implemented additional functionality, such as pinch to zoom or to activate certain subroutines attached to predefined gestures.
HTC One uses a 4.7 inch, 1080p Super LCD 3 touchscreen display with a pixel density of 468 ppi. [32] The backside of the device houses the camera, the LED flash, and the secondary microphone. At the top of the device is a 0.14-inch (3.6 mm) headphone jack and the power/lock key, which also functions as an infrared blaster.
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 ...
