Pressure Touch, Twist and Pan Gesture Input on Unmodified Smartwatches
WatchMI: Watch Movement Input, an innovative way to interact with an Android Wear smartwatch by enhancing touch interaction to support continuous pressure touch, twist, pan gestures and their combinations. Our novel approach relies on software that analyzes, in real-time, the data from a built-in Inertial Measurement Unit (IMU) in order to determine with great accuracy and different levels of granularity the actions performed by the user, without requiring additional hardware or modification of the watch. The app is comprised of 3 parts. The first is a demo of the 3 techniques. The second is a user performance evaluation of each technique using targeting trials, and the final is a group of apps including maps, clock and music to demo the techniques in context.
