Abstract: A capacitive touch system and a sensing method thereof are disclosed. The capacitive touch system includes a touch panel including a plurality of driving electrodes and a plurality of sensing electrodes; a touch control chip; and an external device configured to transmit data to the touch control chip. In a position detection mode, the touch control chip drives the driving electrodes, reads a sensing signal from the sensing electrodes, and determines a position of a touch according to the sensing signal. In a data receiving mode, the touch control chip receives the data transmitted by the external device after a time delay period. In the capacitive touch system and the sensing method thereof, the position detection mode and the data receiving mode can be sequentially performed by delaying the time period.

Abstract: The disclosure provides an active stylus pen and signal transmission methods for the active stylus pen and a touch panel. The stylus has a touch module, a switching module, a signal comparison module, a control module and a pressure sensing module. The stylus determines a first signal generated by a touch panel, and compares an intensity of the first signal and a reference value through a first transmission path. When the intensity of the first signal exceeds the reference value, the stylus outputs a second signal to the touch panel. After the stylus outputs the second signal to the touch panel, the stylus switches to a second transmission path from the first transmission path. The stylus outputs a header signal to the touch panel. When determining a first time sequential distribution, the stylus outputs at least one bit of a pressure signal according to a second time sequential distribution.

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.
