Abstract
Haptic feedback control devices of the present invention include several embodiments. One embodiment includes a housing and a pair of moveable pincher members coupled to the housing. Each pincher member is contacted by a finger of the user when the device is operated and moveable in a degree of freedom approximately within a single plane. An actuator outputs force feedback on the pincher members and a sensor detects a position of the pincher members in the degrees of freedom. The device housing can include a fixed portion and a moveable portion, where the user contacts both fixed and moveable portions. A coupling, such as a flexure, allows the moveable portion to move relative to the fixed portion in a direction parallel to an outer surface of the moveable portion contacted by the user. An actuator outputs a force on the flexure to cause the moveable portion to move, such as an oscillating force to cause vibration. These improvements allow a user to feel force feedback and tactile feedback when operating the device. Applications include telemanipulator devices as well as interface devices and game controllers for computers.
