Each summer, Carleton hosts a group of high school students for Shad Valley’s summer enrichment program in sciences, engineering, technology and entrepreneurship. We held a half-day workshop in our lab for some of the students interested in HCI. Students imagined new applications as they learned about multitouch tabletop technologies, pretended to be attackers as they learned about usable security, and thought of new authentication mechanisms as they tried out the haptic input device.
