Over Spring Break 2017, I presented and demonstrated my work at TEI 2017, which was held in Yokohama, Japan. TEI is an annual international SIGCHI conference dedicated to HCI researches on Tangible, Embedded, and Embodied Interactions. In its 11th year, the conference’s theme was a Japanese proverb: 温故 知新 — you need to recall the past to understand the future. A variety of tangible interaction research projects were presented and demonstrated, both looking back at the past and offering a glimpse of the future. My work, Button+: Supporting User and Context Aware Interaction through Shape-Changing Interfaces, was selected as one of the full papers for presentation during TEI. Many fellow students, professors, and researchers from the United States, Europe, and Asia visited the demo booth to see Button+.
Button+ is a prototype of a shape-changing button interface that was designed, experimented to build a taxonomy of shape-changing interface, in respect to context and user aware scenarios. We focused on the study of a single pushbutton, to simplify our study and to show that this concept can be applied to complicated combinations of buttons. Myself and my teammate presented two supposed applications with Button+, which were a car game and a music player, triggered by predefined RFID cards for simple presentation of the idea.
