| Popis: | 102 We present TouchSense, which provides additional touchscreen input vo- cabulary by distinguishing the areas of users’ finger pads contacting the touch- screen. It requires minimal touch input area and minimal movement, mak- ing 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 en- ter 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. As a proof of concept, we developed a TouchSense smart watch prototype using inertial measurement sensors, and three example ap- plications: a calculator, a map viewer, and a text editor. In a follow-up study, we further reported user performance and user feedbacks on the TouchSense applications. |
