Travel System using Force Sensing Resistors in Immersive Virtual Environments

摘要

A travel system using FSR(Force Sensing Register) sensors in an immersive virtual environment is provided to enable a user to control a traveling speed and direction easily in the immersive vertical environment by using two flexible pressure sensors without using a mouse or a joystick. A travel system is equipped with a first and second flexible pressure sensor(12,14), and a control unit(20) including an ADC(Analog/Digital Converter)(22), which converts an analog signal including information for a pressing sequence and pressure of the first/second pressure sensor into digital data. The first and second pressure sensor is an FSR sensor decreasing resistance when force applied to one active surface of the sensor is increased. The FSR sensors are closely arranged in one line, and comprises an upper FPCB(Flexible Printed Circuit Board) printing a semiconductor in the active area, a lower FPCB printing a pair of electrodes to another active area facing one active area, and a spacer adhering the upper and lower FPCB, and having an opening part corresponding to the active areas. The ADC outputs a pressure level by converting the analog signal into 128-step digital data.
