A group of 11 students spent the week learning about wearable technology, and then presented their projects showcasing their programmed simple circuits and how they work. ÀÖ²¥´«Ã½ used custom-built prototyping tools that Hill and co-leader Michael Schneider designed to help the students prototype circuitry. Both Hill and Schneider work with Mark Gross, professor of computer science, and Ann Eisenberg, senior research associate with the Institute of Cognitive Science, on the NSF-sponsored Debugging by Design grant.
