Set at the Cal Design Lab at the College of Environmental Design at UC Berkeley, this workshop will explore the expressive possibilities of recognizing and using motion to build more "intuitive" systems in domains such as architecture, public art and industrial design. Workshop participants interested in modern-day applications of motion studies and social factors examine the current state of the art in sensing and actuation technologies that detect and perform motion, applying this knowledge to working prototype designs. This is useful in designing automated windows or doors, or reactive public displays. Participants will be given tutorials in basic computation, electronic, micro-controller, sensor and actuation technologies. Workshop exercises include the construction of simple automata, design of public-scale reactive displays, and improvisational video prototyping. This workshop will be led by Wendy Ju, the program coordinator for the Cal Design Lab.
