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.
