Abstract
A virtual reality system is described herein. The virtual reality system includes a cane controller and a computing system. The cane controller comprises a rod, a sensor, and a brake mechanism, wherein the sensor is configured to generate a signal that is indicative of position, direction of movement, and velocity of the rod, and wherein the brake mechanism is configured to apply a force to the rod. The computing system receives the signal, computes a position, direction of movement, and velocity of a virtual rod in a virtual space, and outputs a control signal to the brake mechanism based upon such computation. The brake mechanism applies the force to the rod in a direction and with a magnitude indicated in the control signal, thereby preventing the user from causing the virtual rod to penetrate a virtual barrier in the virtual space.
