HAPTIC FEEDBACK PROVIDING DEVICE AND METHOD THEREWITH

摘要

PURPOSE: A haptic feedback providing device and a method thereof are provided to simultaneously supply a skin haptic stimulus due to a vibration unit and a muscle haptic stimulus due to a viscosity change, thereby providing haptic feedback similar to a feeling when a user touches an object. CONSTITUTION: A user touches an upper plate(310). A vibration unit generates vibration in the bottom of the upper plate. The first electricity applying unit applies electricity to the vibration unit. A fluid pipe(410) is installed in the bottom of a skin haptic unit(300). The inside of the fluid pipe is filled with rheological fluid. The second electricity applying unit applies electricity to the fluid pipe. A control unit(100) controls the first electricity applying unit and the second electricity applying unit.
