Tutorial 3: Touch Sensing Technologies


Florian Echtler


Sunday November 7th, 13:30-15:00


During the last few years, a tremendous amount of interactive surfaces have been constructed in research labs around the world. Although commercial devices have been available for some time now, the flexibility afforded by custom-built interfaces is still a major factor, particularly for experimental setups.

In the first part of this tutorial, a comprehensive overview of touch sensor technologies, both commercial and do-it-yourself, will be given. In the second part, a number of advanced techniques for infrared-optical sensing will be presented with a particular focus on custom-built setups. These techniques serve to mitigate some of the problems inherent to optical sensors, e.g., susceptibility to stray light.
