In this senior course, students hone their digital interactive design skills. Students study interaction design, industrial design, and cognitive science in order to focus on the mental models and specific gestures that allow humans to interact with the designed world. Interface conventions are deconstructed and rebuilt. Interaction models are built and tested. The future of interface as invisible computing is explored and prototyped. At the conclusion of the course, students demonstrate an understanding of how and why some digital products “feel good” to use, and how to use those findings within a user-centered design process to better their design solutions.
