Abstract
A digital input device for entering data into a digital system, comprises at least two remote sensors and a control unit. A working area is set up in proximity to the sensors and the position of an object within the working area is detected by the input device based on data provided by each sensor and transmitted, by said control unit, to said digital system. The position of an object outside said working area, if detected by said input device, is rejected by said control unit and is not transmitted to said digital system. The sensors can be ultrasonic sensors and the object can be a part of the body of a user. Use of a third sensor allows three-dimensional detection of the object.
