Definition: PixelSense

(1) Microsoft's touchscreen technology that was introduced with its multitouch computer (see definition #2 below).

(2) A Windows-based multitouch tabletop computer from Microsoft that incorporates hand gestures and recognition of objects placed on or in front of the screen. Every screen pixel functions like a camera.

The PixelSense was designed for group participation without the use of a mouse or keyboard. Introduced in 2008 under the Microsoft Surface brand with a 30" rear projection screen, the unit was rebranded as Microsoft PixelSense in its second incarnation.

The PixelSense includes multitouch along with gesture and optical recognition. In this light table example, photos are being moved around as if they were printed on paper, but can also be resized using hand movements. (Image courtesy of Microsoft Corporation.)
