Patent attributes
A virtual reality input and haptic feedback system for sensing hand movements of a user, the system comprises a processing device, a wearable object to be worn on the hand of the user, a sensor system, a sensor, an electronic control device, and a feedback system. The feedback system comprises at least one fluidic actuation device, at least one expandable member, at least one movable valve, and a haptic feedback device. The haptic feedback device has a variable surface configured to simulate the softness or texture of a virtual surface. The processing device calculates the strength and amplitude of provided feedback to each part of the user's hand from the input data, and controls the fluid actuation device and the movable valve, such that the expandable member expands under increased pressure to maintain an airtight seal, or contracts under reduced pressure, and causes a change in the surface of the haptic feedback device, thereby providing the simulated pressure and the haptic senses of surface texture for the user's hand.
