Abstract:
A haptic feedback device for virtual objects includes a head-mounted display unit, an HMD control unit, a haptic feedback unit, and a haptic information DB for storing haptic information in association with each type of virtual object. The HMD control unit includes a display controller that causes a virtual object and a user focus to appear on a display, and a haptic information transmitter that reads, when the user focus is placed over a selectable virtual object, haptic information associated with the type of the selected virtual object from the haptic information DB, and transmits the haptic information to the haptic feedback unit. The haptic feedback unit includes a movable portion movable with a user operation, a movement resistance generator that applies movement resistance to the movable portion, and a power feed controller (movement resistance controller).
