The goal of this course is the application of sensor technology to areas such as new audiovisual interfaces, music/sound manipulation and spatialization systems, interactive installations/virtual environments, 2D/3D video and graphics interfaces and other innovative devices for interacting with and manipulating computer systems. It is expected that the course will lead to a completed prototype of some sort as a final project. A student who successfully completes this course will have experienced taking an original interface through a full cycle of design, prototype, evaluation and testing. The system demonstrated at the end of the term should explore the relation between a physical interaction and some kind of media, and is to be accompanied with a written report / web site describing the intent and an evaluation of the interface. Lectures and examples will feature state-of-the-art environments used at UCSB, particularly in the AlloSphere Research Group.
