Abstract
A 2D occupancy system for determining a position of a user (e.g. a human, an object or an animal) in an environment includes a host device and a plurality of motion detection devices. The host device and the plurality of motion detection devices are connected through a network. Each motion detection device has a viewing angle and the viewing angle of any motion detection device overlaps with the viewing angle of at least one other motion detection device. The host device comprises an input port for receiving motion information from the plurality of motion detection devices, and a processing unit for determining the position of the user in the environment from the motion information from particular motion detection devices at a same time-stamp.
