Multi-Touch

Multi-Touch Technology
Multi-Touch-based devices accept input from multiple fingers and multiple users simultaneously, allowing for complex gestures, including grabbing, stretching, swiveling and sliding virtual objects across the table. While touch sensing is commonplace for single points of contact, multi-touch sensing enables a user to interact with a system with more than one finger at a time, as in chording and bi-manual operations. Demos 1, Demos 2.


Such sensing devices are inherently also able to accommodate multiple users simultaneously, which is especially useful for interactive walls and tabletops. Multi-Touch is already widely used. Apple’s iPhone has Multi-Touch scrolling and picture manipulation.
