Abstract
An input interface for a virtual reality (VR) system includes one or more actuators stressing or straining a portion of a user's skin, simulating interactions with presented virtual objects. For example, an actuator comprises a tendon contacting portions of a user's body and coupled to a motor that moves the tendon to move portions of the user's body contacting the tendon. Alternatively, an actuator includes a pad having a surface contacting a surface of the user's body. A driving mechanism moves the pad in one or more directions parallel to the surface of the user's body with varying levels of normal force. In another example, one or more pins contact portions of the user's body and a surface of a bladder. The pins move as the bladder is inflated or deflated, which moves the contacted portions of the user's body. Alternatively, another type of actuator may move the pins.
