Virtual Hand: VR Hand Controller Using IMU and Flex Sensor

Virtual Reality is a new field on technology industry that has been growing rapidly for the last decade. One of the improvements made from this industry is Virtual Reality Glove or VR Glove which is an improvement for Virtual Reality Controller. Although the glove is popular on PC market, there has yet to be any glove for the smartphone market, even though both markets has the same potential. The purpose of this paper is to make a glove controller for a VR application that can be integrated into smartphone. Taking example from other papers, an Inertial Measurement Unit (IMU) sensor can capture an object angular rotation and using said rotation, use it to form a forward kinematic to determine the glove position. In Order to allow communication between the devices and the target smartphone and to be able to configure its connection, a Wi-Fi Module and a small microcontroller board is required. A microcontroller board capable to do both Wireless connection and act as a microprocessor is ESP32 board. The test results of this project indicate a 1% error on the device rotation and also a delay in simulation of 10 times the time required to rotate the device.
