Abstract: The invention provides a non-tactile control arrangement including an array of light sensors 5, an array of light emitters 4, each one of which is adapted to illuminate, and thereby cause an output signal to be generated by, at least a respective one of the array of light sensors, detection means for detecting the output of each of one of array of light sensors and providing an output signal indicative of a change of state of the outputs of the array of sensors. The presence or absence of illumination of any one or more of the light sensors is detected by the detection means which provide an output in the form of a set of binary digits, in a suitable format, for use in the control of equipment, for example, a computer. The arrangement may be incorporated in a frame 1.
