To touch: Multi-Touch Interaction Research

Bi-manual, multi-point, and multi-user interactions on a graphical interaction surface.

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. 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.
