New Technology- Multi-touch

Saturday, September 8, 2007

Multi-touch is a human-computer interaction technique and the hardware devices that implement it. Multi-touch consists of a touch screen or touch tablet (touchpad) that recognizes multiple simultaneous touch points and software to interpret simultaneous touches. This frequently includes the position and pressure or degree of each touch point independently, which allows gestures and interaction with multiple fingers or hands (similar to chording) and can provide rich interaction (including direct manipulation) through intuitive gestures. Depending largely on their size, some multi-touch devices support more than one user on the same device simultaneously. One salient aspect of this technique is that it makes easy to zoom in or out in a Zooming User Interface with two fingers, thereby providing a more direct mapping than with a single-point device like a mouse or stylus.
Multi-touch has at least a 25 year history, beginning in 1982, with pioneering work being done at the University of Toronto (multi-touch tablets) and Bell Labs (multi-touch screens). In July 2007, Apple made a move to register the word multi-touch as a trademark.
