An input device with three-dimensional, six-degrees-of-freedom data input for a computer having an array of tracking points (110) defining a first axis and a second axis or plane is described. Light reflected from, or given off from the tracking points (110), is captured by an imaging device (130). From the two-dimensional images captured, three-dimensional data relating to the position and orientation of the input device may be obtained from the relative positions of the tracking points (110) by a provided algorithm and lookup table. In the preferred embodiment of the invention, tracking points on the input device which is in the form of a wand (101) with a cross piece (120) and an imaging device (130) allow computer users to input swinging movements into a virtual environment for gaming or three-dimensional applications.
