Abstract: A method for identifying tap events on a touch panel includes measuring vibration signals for tap events on the touch panel to collect the tap events and record types of the tap events as samples; generating a sample set including a plurality of samples; using the sample set to train a deep neural network to determine an optimized weighting parameter group; taking the deep neural network and the optimized weighting parameter group as a tapping classifier and deploying it to a touch-controlled end product; and obtaining a predicted tap type based on a vibration signal and an image formed by touch sensing values detected by the touch-controlled end product to which a tap operation is performed. The present disclosure also provides a system corresponding to the identifying method, and a touch-controlled end product.

Abstract: 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.
