Multi-Touch Interaction Research

© 2006, Jefferson Y. Han

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.

Since developing the FTIR (frustrated total internal reflection) technique, we've been experimenting with a wide variety of application scenarios and interaction modalities that utilize multi-touch input information. These are far more interesting than the typical poking-of-the-touchscreen or the gross silhouette gesturing found in most interactive installations of this scale. It is a rich area for research, and we are extremely excited by its potential.

The sensing technology is force-sensing, and provides unprecedented resolution and scalability, allowing us to create sophisticated multi-point widgets for applications large enough to accomodate both hands and multiple users.

The drafting table style implementation shown here measures 36"x27", is rear-projected, and has a sensing resolution of ~0.1" at 50Hz. Applications receive stroke event information using the lightweight OSC protocol over UDP.

Ill like to know the name of the song. Thks

i read in a popular science that the interface modeled in Minority Report was based off one similar being developed at MIT. I've seen video of ones similar, but not the one that Minority Report was based on

and the next step are a couple of glove like the ones of Tom Cruise in "minority report"? that could be handy

Your work is extremely cool! I have a question: in a world in wich every PC is able to collect user need with your kind of interfaces, we will have a role for remote tracking of user needs, and virtual-intelligent assistant also? ...or we will spend our life on "microsft windows" forever, but drawing on a tablet with you sw?
