As multimedia becomes an integral part of collaborative systems, we must understand how to design such systems to support users’ rich set of existing interaction skills, rather ...
We believe that navigation in information spaces is best supported by tapping into our natural spatial and geographic ways of thinking. To this end, we are developing a new comput...
We present an efficient and robust algorithm for finding points of collision between time-dependent parametric and implicit surfaces. The algorithm detects simultaneous collisio...
