Multi-Touch Interaction

While touch-sensitive screens commonly work 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. Such sensing devices are inherently also able to accommodate multiple users simultaneously, which is especially useful for larger interaction scenarios such as interactive walls and tabletops.

Developed by Jefferson Han at New York University, Multi-Touch Interaction offers a wide variety of application scenarios and interaction modalities that utilize multi-touch input information. These go far beyond the “poking” actions you get with a typical touch screen, or the gross gesturing found in video-based interactive interfaces.

Multi-Touch Interaction is force-sensitive, and provides unprecedented resolution and scalability, allowing the creation of sophisticated multi-point widgets for applications large enough to accommodate both hands and multiple users.
