Patent attributes
Methods and apparatus provide for controlling an operating device, wherein the operating device includes: (i) a grip part to be gripped by a user; and (ii) an operation part for activation by a finger of the user gripping the grip part, where the operation part includes: (i) a movable part capable of moving from a resting position toward another position in response to a force applied by the finger of the user, (ii) a biasing element operating to urge the movable part toward the resting position, (iii) a sensor operating to measure the force applied by the finger of the user to the movable part and produce a sensing signal therefrom, and (iv) a motorized assembly operating to receive a drive signal, and in response, apply an amount of force to the movable part in opposition to the force applied by the finger of the user, and where the drive signal is a variable dependent on variations in the sensing signal, such that the amount of force applied to the movable part in opposition to the force applied by the finger of the user provides the user with haptic feedback.
