Abstract: A device for providing user input to a computer includes a base member with a tracking sensor. A vertically oriented pistol grip member is disposed at an aft portion of the base member and extends upward therefrom. A pistol barrel member extends forward from an upper portion of the pistol grip member. The counterweight is disposed toward the aft portion of the base member so as to counterbalance a weight of the pistol barrel member and a weight of the pistol grip member. The counterweight can also provide a stabilizing force when the user holds and operates the pistol grip member.

Abstract: A device for providing user input to a computer includes a base member that has a base axis. A tracking sensor for sensing motion of the base member is mounted in the base member at a sensor location along the base axis. A vertical grip member extends upward from the base member. A major axis of the vertical grip member intersects the base axis at a grip axis location that is offset from the sensor location by a distance greater than zero.

Abstract: A device for providing user input to a computer includes a vertical grip member that has a trigger disposed on a forward surface thereof so that the trigger is operable by a first finger of a hand holding the grip member. A first single throw electrical switch coupled to the trigger generates signals in response to depression of the trigger.

Abstract: A device for providing user input to a computer includes a base member with a tracking sensor for detecting motion of the base member and a vertical grip member that extends upward from the base member. A scroll wheel is rotatably mounted in the grip member and oriented so as to be rotatable by a substantially arc-like movement of a thumb of a hand holding the grip member.

Abstract: A device for providing user input to a computer has a trigger disposed on a forward surface of a vertically oriented grip member so that the trigger is operable by a first finger of a user's hand, and button input signals are generated in response to operation of the trigger. A scroll wheel is rotatably mounted on the grip member and is positioned so as to be operable by the user's thumb, and scroll input signals are generated in response to operation of the scroll wheel.
