Method and apparatus for computer input using six degrees of freedom

A computer input device includes a camera for capturing an image of a pattern on a surface. A processor in the computer input device determines equations for lines from the image of the pattern, applies the line equations to a transform to form transformed line equations, and uses the transformed li...

Zusammenfassung:A computer input device includes a camera for capturing an image of a pattern on a surface. A processor in the computer input device determines equations for lines from the image of the pattern, applies the line equations to a transform to form transformed line equations, and uses the transformed line equations to determine the height of the computer input device above the surface.
