Multi-Touch Interaction Research


Jefferson Y. Han and coll. have developed multi-touch sensing technologies based on a technique called FTIR (frustrated total internal reflection), originally developed for fingerprint image acquisition. It acquires true touch information at high spatial and temporal resolutions, and is scalable to very large installations.

Multi-touch sensing allows 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 also able to accommodate multiple users simultaneously, which is especially useful for larger interaction scenarios such as interactive walls and tabletops.
