Abstract
A processor can determine a relative position within a room of a person wearing a force-on-force device based exclusively upon sensed optical signals detected by optical sensors connected to the force-on-force device. Each of the sensed optical signals is geographically focused within a spatially constrained zone. Each sensed optical signal can further include digitally encoded data indicating an optical source that emitted the sensed optical signal and a spatially constrained zone of the sensed optical signal. The relative position can be determined based on determining a grid within the room within which the person is located. The grid can be defined by overlapping ones of the spatially constrained zones of the sensed optical signals.
