TouchSense: Expanding Touchscreen Input Vocabulary Using Different Areas of Users' Finger Pads. Huang, D., Tsai, M., Tung, Y., Tsai, M., Yeh, Y., Chan, L., Hung, Y., & Chen, M. Y. In Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, of CHI '14, pages 189--192, New York, NY, USA, 2014. ACM. 00000Paper doi abstract bibtex We present TouchSense, which provides additional touchscreen input vocabulary by distinguishing the areas of users' finger pads contacting the touchscreen. It requires minimal touch input area and minimal movement, making it especially ideal for wearable devices such as smart watches and smart glasses. For example, users of a calculator application on a smart watch could tap normally to enter numbers, and tap with the right side of their fingers to enter the operators (e.g. , -, =). Results from two human-factor studies showed that users could tap a touchscreen with five or more distinct areas of their finger pads. Also, they were able to tap with more distinct areas closer to their fingertips. We developed a TouchSense smart watch prototype using inertial measurement sensors, and developed two example applications: a calculator and a text editor. We also collected user feedback via an explorative study.
