One common type of haptic interface currently in use is a device consisting of a glove or manual exoskeleton that monitors hand position and posture (i.e., finger joint angles). These devices, like head-position trackers, provide no feedback and are used solely for control. Other devices, such as force-reflecting joysticks, act as tool handles and serve not only a control function but also a display function because they are capable of providing force feedback.
