Multi-Touch Interaction Research

Bi-manual, multi-point and multi-user interactions on a graphical display surface. While touch sensing is normal for single points of contact, multi-touch sensing enables a user to interact simultaneously with a system with more than one finger, as business agreements and bi-manual. Such sensing devices are inherently also able to accommodate multiple users simultaneously, which is particularly useful for larger interaction scenarios such as interactive walls and tables. Since the refiningFTIR (frustrated total internal reflection) sensing technique, we experimented with a variety of application scenarios and interaction modalities that utilize multi-touch input information. This goes far beyond the "shock" action you get with a typical touch screen, or crude gestures in interactive video-based interfaces are found. It is a rich field of research, and we're thrilled the potential for advances in efficiency, convenience and clarity excited. It 's justso funny! Our technique is sensitive to the Force, and provides unprecedented resolution and scalability, allowing us to create sophisticated multi-point widgets for applications large enough to adjust both hands and multiple users. The drafting table style implementation shown here measures 36 "x27", rear projection, and an effective range resolution better than 0.1 "at 50Hz.
