摘要:
A computer system, including data-processing equipment and a freely movable input device, wherein the input device contains at least one position change sensor from which information can be sent to the data-processing equipment and wherein the data-processing equipment can also capture information about the absolute position of the input device. Information about the absolute position of the input device can be captured by the data-processing equipment as a result of the fact that the data-processing equipment is in data communication with a light-sensitive, position-sensitive input surface and the input device emits a light beam, the point of incidence of which on the input surface can be detected by the latter.

A computer system that includes a data-processing unit, a touch-sensitive, position-resolving input surface in data communication with the data-processing unit, and a freely movable input device, by which the input surface is to be touched for the purpose of inputting into the data-processing unit. The freely movable input device is a computer mouse, which is in data communication with the data-processing unit. With comparatively low sensor complexity, inter alia, both the absolute position of the computer mouse and also subtle position changes of the computer mouse can therefore be very easily detected by the data-processing unit.

摘要:
A real-time measurement of relative position data and/or of geometrical dimensions of a moving body by lighting unit and a detector unit, wherein the moving body is movably guided relative to both of the units. Light beams are transmitted from the lighting unit towards the detector unit; the moving body protrudes between the lighting unit and the detector unit into the volume flooded by the light beams, so that the shadow border of the shadow thrown by the moving body extends over the detector unit. The detector unit includes a two-dimensional optical position detector, which is designed as a two-dimensional optical waveguide containing photo-luminescent particles. Signals from the two-dimensional optical waveguide are read out by a plurality of small-area photoelectric sensors spaced apart from one another, the strength of the signals correlating with the intensity of the light at the sensor location in waveguide mode.
