This course examines architecture's emerging relationship with the design of interactivity, interfaces, and information infrastructures. Working mainly in seminar format, in response to short weekly readings, participants debate issues in the past, present, and future of technology-laden places. Biweekly lectures explore how places have generally emerged at crossovers between infrastructures. Biweekly storyboard projects interpret architecture and the city in terms of interaction design. A final project invites a situational design proposition. Emphasis is on how computing now pervades the physical world, however, and not on dematerialization. This course attempts to take apart popular misconceptions of cyberspace, and to reassert the value of embodied architecture in a digital economy.
