-1- ABSTRACT An optical cursor control device or "optical mouse" is disclosed for use with an interactive, display oriented computer system to provide movement for a visible cursor from position to position on a display screen of such a system. The cursor control device provides an output indicative of the amount and direction of movement of the device relative to an orthogonal coordinate system. The device relies on a planar grid pattern comprising orthogonally positioned grid lines of uniform spacing, one line and spacing defining a grid period. Means is provided to illuminate at least a portion of the grid pattern. Sensor array means comprising optical transducers are provided for each orthogonal direction. Each optical transducer has an elongated radiation detecting area to receive radiation from an elongated radiation collecting area at the plane of said grid pattern. The length of the radiation collecting area of each transducer is equal to or greater than a grid period and the width of these areas is equal to or narrower than the width of one half of the grid period.
