  • Patent number: 8471686
    Abstract: A remote control apparatus that provides haptic sensations. The remote control apparatus includes a dial, a motor, a rotary encoder, an encoder counter, a control unit and a motor controller. The remote control apparatus further includes a storage unit, a movement detection unit and a display unit. When a user selects an icon displayed on the display unit by rotating the dial, the control unit interprets the user instruction through the rotary encoder and the encoder counter to control the motor to generate torque for causing a haptic sensation corresponding to the interpreted instruction via the motor controller. While the haptic sensation is conveyed to the user through the dial, the control unit controls an appliance to perform the interpreted instruction thereon.
