Abstract
A system and method for determining the position of an object in a space includes positioning the object within the overlapping detection fields of a plurality of analog proximity sensors, wherein the proximity sensors produce an output signal having a signal strength related to the proximity of the object to the sensors. The strength of the output signal produced by each analog proximity sensor can be detected and a position for the object established based on the relative signal strengths produced by the proximity sensors. The system and method have particular application with devices for gestural control, for example gestural controlled dimmer switches, where some data manipulation is required to generate high-resolution positional data to activate the device.
