USER INTERACTION METHOD BASED ON STYLUS, SYSTEM FOR CLASSIFYING TAP EVENTS ON STYLUS, AND STYLUS PRODUCT

摘要

A novel method is proposed to operate a stylus product. In this method, inertial measurement unit (IMU) signals are used to estimate a tilted angle of the stylus product. On the other hand, acceleration signals measured when a finger taps a stylus are collected to train a deep neural network as a tap classifier. A combination of the tilted angle and the tap classifier allows a user to interact with a peripheral device (e.g. a touchscreen) by rotating and taping the stylus product. A tap classifying system and a stylus product are also provided.
