Colloquium Information:


Providing humans with improved multi-sensory feedback (graphics, haptics, audio, etc.) in virtual environments and interactive human-computer applications can improve task performance, and provide more compelling experiences. Unfortunately, most physical simulation algorithms are simply not designed to provide real-time feedback at the high temporal sampling rates associated with human perception--graphics feedback at 60 Hz, kinesthetic haptic force feedback at 1 kHz, and audio feedback at 44 kHz. The intertwined complexities of detailed geometry, solid mechanics, collision detection, frictional contact mechanics, sound radiation, hardware interfaces, etc., all conspire to make multi-sensory feedback a challenging task. In this talk I will describe some of our recent and on-going work on new algorithmic approaches for simulating mechanical systems with real-time multi-sensory feedback.

Refreshments will be served
