WatchMI: Applications of watch movement input on unmodified smartwatches

Abstract

In this demo, we show that it is possible to enhance touch interaction on unmodified smartwatch to support continuous pressure touch, twist and pan gestures, by only analyzing the real-time data of Inertial Measurement Unit (IMU). Our evaluation results show that the three proposed input interfaces are accurate, noise-resistant, easy to use and can be deployed to a variety of smartwatches. We then showcase the potential of this work with seven example applications. During the demo session, users can try the prototype.
