METHOD AND SYSTEM FOR PROVIDING A ROUGHNESS HAPTIC OF A VIRTUAL OBJECT USING SPATIOTEMPORAL ENCODING

摘要

A method and system are disclosed for providing a roughness tactile sense of a virtual object using spatiotemporal encoding. A method of providing a roughness tactile sense of a virtual object includes: displaying the virtual objects to a user; tracking the location of the user''s hand; predicting a virtual object most likely to collide with the hand from among the virtual objects; and when the hand comes into contact with the tactile sense providing device, controlling the tactile sense providing device according to the predicted surface roughness of the virtual object and feeding back the rough tactile sense to the user.
