Design of smart input devices

Abstract

As the size of the chip is getting smaller and the processing speed is getting faster and faster, various smart products are also constantly being upgraded. Multimedia is widely used in teaching. Traditional laser pointers can no longer meet people's needs. Electronic stylus chips can enhance the interaction between human and computer. The smart electronic stylus uses a gyroscope and accelerometer to collect position and speed information, then transmits the information to the smart display device via Bluetooth.
