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.

Abstract: A circuit for touch sensing includes a driving unit, a self-capacitive sensor circuit, a mutual-capacitive sensor circuit and a control circuit. The driving is configured to generate a driving signal. The self-capacitive sensor circuit is configured to generate a self-capacitance sensing result. The mutual-capacitive sensor circuit is configured to receive the driving signal in order to generate a mutual-capacitance sensing result when the voltage of a node between the self-capacitive sensor circuit and the mutual-capacitive sensor circuit reaches a reference voltage. The control circuit receives and computes the self-capacitance sensing result and the mutual-capacitance sensing result in order to generate a sensing result. By utilizing the circuit for touch sensing of present disclosure, the accuracy and the efficiency of touch sensing can be enhanced.
