Development of a Hand-operated Wearable Mouse for Virtual Reality

If the movement of the hand is dataized, it can be applied and used in various fields such as operating drones, vehicles, and the prosthetic arms. In this study, hand movements were recognized using electromyography sensors, inertial sensors and pressure sensors and used for mouse control that can be universally applied in various fields. A device is capable of implementing four functions: left-click, right-click, cursor movement, and wheel scroll was designed and developed. The data obtained through the sensors were stabilized through a low-pass filter and then linked to a PC through Bluetooth communication for the mouse functions and accuracy. Accuracy of functions is 96% for left-click, 70% for drag, 76% for right-click, 79% for wheel scroll. Accuracy of right-click is upgraded by changing electromyography sensor to pressure sensor.
