摘要

"Input device for positioning a cursor on a computer screen by movement of a ball on a substrate, and process for detecting the rotation angle of a sphere.As a sphere in an input device of the present invention provides a computer input device for positioning a cursor on a computer screen by motion of a sphere(2) whose rotary movements are transformed into electronic signals, which is only those markings that are provided to magnetically detectable sphere (2).Capable of being detectable by a magnetic reading unit (11) so that the rotation of the sphere is converted into data values with respect to an X axis and a Y axis.Said axes being preferably perpendicular to each other.This provides a detection device compact, which is suitable for the construction of a computer "mouse" in the form of a ball point pen.
