The invention relates to a sensor apparatus and a method for generating electronic signals that are indicative of a spatial position and/or the movement of limbs, especially a user's hand relative to the sensor apparatus. Said electronic signals can then be used for carrying out input processes in data processing devices, communication devices, and other electrical devices. The aim of the invention is to find ways to generate, in a particularly advantageous manner, signals that are indicative of the position and/or the movement of limbs. Said aim is achieved by a sensor apparatus for generating electrical signals that are indicative of the position or movement of limbs relative to a reference area. Said sensor apparatus comprises a transmitter electrode device, a voltage generator for applying an alternating voltage to the transmitter electrode, a first receiver electrode device, a second receiver electrode device, and a third receiver electrode device. The first, the second, and the third receiver electrode device are each connected to high-resistance tapping systems. Preferably, the first, the second, and the third receiver electrode device are each connected to high-resistance inputs of an impedance transformer system. The data indicative of a location or movement is obtained on the basis of differences between the electrical events applied to the outputs of the respective impedance transformer.
