As systems have grown in computational power, it is increasingly apparent that the input/output subsystems are now becoming a bottleneck for the user(s). While computer graphics has advanced incredibly to address the output side of this issue, multi-touch input devices and their ability to enable multiple users to reliably input many degrees of freedom continuously and simultaneously hold incredible promise for addressing the input side. We'll review the rich history of this class of input devices and techniques, look at the rapidly advancing state of the art, and finally discuss current directions in the marketplace and their implications.

Jeff Han is founder and chief scientist of Perceptive Pixel, a startup dedicated to the research, development, and marketing of multi-touch interfaces for the knowledge worker. His fields of interest encompass computer graphics and multimedia systems, with a more recent bent towards machine learning and HCI. Jeff studied EE and CS at Cornell University, where he also worked on the classic CU-SeeMe videoconferencing system.
