First Claim
1. A system for estimating at least one control feature of a remote control, the system comprising:
- the remote control comprising;
a camera for;
detecting at least one light point originating from at least one beacon located at or near a device that is to be controlled via the remote control, the at least one light point originating from the at least one beacon comprising;
at least one of a first light point and a second light point originating from respective a first beacon and a second beacon; and
detecting at least one additional light point originating from at least one non-beacon comprising any other light source different from the at least one beacon, the at least one additional light point originating from the at least one non-beacon comprising;
at least one of a third light point and a fourth light point originating from respective first non-beacon and second non-beacon; and

Abstract
An apparatus (1) estimates control features of remote controls (10) comprising cameras (11) for detecting light points (51, 52) from beacons (31, 32) located at or near devices (20) that are to be controlled via the remote controls (10) by letting the cameras (11) further detect light points (61, 62) from non-beacons (41, 42). Processors (2) estimate the control features in response to information from the detections of the light points (51, 52, 61, 62). The non-beacons (41, 42) comprise noise sources or any other sources different from the beacons (31, 32). Memories (3) store per time-interval the information per detection. The light coming from the beacons (31, 32) may be modulated light and the light coming from the non-beacons (41, 42) may be other light. The information may comprise coordinates, sizes and intensities of light points (51, 52, 61, 62) per detection and per time-interval. The control feature may comprise a pointing position, a distance, a rotation, a tilt, a location, a speed, an acceleration, a movement and/or a zoom of the remote control (10).
