ABSTRACT:
An apparatus for determining distance coordinates along two orthogonal axes for a computer system, where the coordinates represent the position of a cursor on a screen of a display unit of the computer system. The apparatus includes a pair of velocity detectors and an operating device such as a CPU. When the velocity detectors are moved by an operator, each of the velocity detectors detects velocities along a respective one of the orthogonal axes. The detected velocities are converted into moving distances representative of the coordinates through a calculation of the operating device.
