Directional remote control
View Patent ↗A remote control unit generates a first beam which a user points at one of a plurality of information appliances to select that appliance. After selecting the desired appliance, the user then actuates a button on a control keypad on the remote control unit to cause the unit to generate a second, modulated beam. The remote control unit modulates the second beam in accordance with a desired functionality of the information appliance to control the appliance accordingly.
1. A method for controlling by a controller a plurality of devices coupled to the controller across a network, comprising:
determining at the controller whether multiple devices or a single device have each received an electromagnetic radiation beam from a user for selecting a device by determining if an acknowledgement in the form of an electrical signal was received from more than the one device, and if multiple devices have each received a beam, then
selecting from among the multiple devices that each have received an electromagnetic radiation beam, a single device to receive control signals; and
performing at the controller at least one network-related activity if required by the selected device.
2. The method according to claim 1 wherein a user selects the single device from among the multiple devices that each has received an electromagnetic radiation beam.
3. The method according to claim 1 wherein the controller selects the single device from among the multiple devices that each has received an electromagnetic radiation beam.
4. The method according to claim 1 wherein the selecting step includes choosing from among multiple devices in accordance with a highest priority device.
5. The method according to claim 1 wherein the selecting step includes choosing from among multiple devices in accordance with a previously designated device.
6. The method according to claim 1 further including the step of deselecting the device after the device completes receiving a control signal.
7. A A controller for controlling a plurality of devices coupled to the controller across a network, the controller including a processor configured to:
identify devices coupled to the controller across the network by periodically sending out service packets to the devices;
determine whether multiple identified devices or a single identified device has each received an electromagnetic radiation beam from a user for selecting an identified device by determining if an acknowledgement in the form of an electrical signal was received from more than the one device, and if multiple devices have each received an electromagnetic beam, then
select from among the multiple devices that each has received an electromagnetic radiation beam, a single device to receive control signals.
8. The controller according to claim 7 wherein the processor selects the single identified device from among the multiple identified devices that each has received an electromagnetic radiation beam.
9. The controller according to claim 7 wherein the processor chooses from among the multiple identified devices in accordance with an identified device having highest priority.
10. The controller according to claim 7 wherein the processor chooses from among multiple identified devices in accordance with an identified device that was designated previously.
11. The controller according to claim 7 wherein the processor deselects the selected identified device after said device completes receiving a control signal.
