Abstract:
A method of selecting and controlling devices based on wireless communication technology. The wireless controller sends a probe message to one or more devices; each device receives the probe message, obtains information in respect of its relative position with respect to the wireless controller, determines a response time to respond according to a first predefined rule, based on its relative position information: detects response signals from other devices before expiration of the response time; decides whether to send or not to send its response signal according to a second predefined rule and the detecting procedure of response signals from other devices; the wireless controller receives response signals sent by the devices after the comparison of the relative position information of each device with respect to the wireless controller, and selects the target devices from the devices. Embodiments of the present invention reduce the complexity, delay and energy consumption of the selection for wireless devices, and are especially applicable for wireless lighting systems.

Abstract:
The invention is directed at a remote control device for controlling one or more user devices, comprising a directional optical sensor for receiving one or more optical signals from the user devices and for detecting an incoming direction of said received optical signals, and a processor. For identification of at least one of said user devices, the processor is arranged for analyzing at least one of said received optical signals for associating thereof with the at least one of said user devices and for keeping track of the at least one of said optical signals upon changing of said incoming direction. The one or more optical signals comprise high and low signal states, wherein each optical signal consists of one or more signal fragments. Each signal fragment comprising a leading or trailing low signal state and a high signal state, wherein a duration of the high signal state determines a signal fragment type of the signal fragment and wherein said duration of the high signal state is longer than a duration of the low signal state. The processor is arranged for performing said associating of said at least one received optical signal with the at least one of said user devices by recognition of the one or more signal fragments and associating each signal fragment with its signal fragment type for obtaining therefrom a signal pattern which is uniquely associable with said at least one of said user devices.
