WatchMI: pressure touch, twist and pan gesture input on unmodified smartwatches

This work presents WatchMI: Watch Movement Input that enhances touch interaction on a smartwatch to support continuous pressure touch, twist, pan gestures and their combinations, and relies on software that analyzes, in real-time, the data from a built-in Inertial Measurement Unit to determine with great accuracy and different levels of granularity the actions performed by the user.
