LIGHTING PREFERENCE ARBITRATION
First Claim
1. A controller comprising:
- an output for controlling one or more light source arranged to emit light to illuminate an environment; and
an input for receiving a signal output from at least one sensor;
wherein the controller is configured to;
identify presence of a user and at least one further user in said environment based on the signal output from the at least one sensor;
determine lighting preferences of the user and the at least one further user;
detect an orientation of the user and the at least one further user based on the signal output from the at least one sensor;
estimate a field of view of the user and the at least one further user based on the detected orientation of the user and the at least one further user;
determine that at least one light source of the one or more light source is positioned to emit light in both the field of view of said user and the field of view of said at least one further user, arbitrate between the lighting preferences of the user and the at least one further user to determine light settings to be applied to the at least one light source, and control said at least one light source based on the determined light settings.

Abstract
A controller comprising: an output for controlling light source(s) arranged to emit light to illuminate an environment; and an input for receiving a signal output from at least one sensor. The controller is configured to: identify presence of a user and at least one further user based on the signal output from the sensor; determine lighting preferences of the users; detect an orientation of the users based on the signal from the sensor; estimate a field of view (FOV) of the users based on the detected orientation of the users; determine that at least one light source is positioned to emit light in both the FOVs of the users, arbitrate between the lighting preferences of the users to determine light settings to be applied to the at least one light source, and control said at least one light source based on the determined light settings.

11. The controller according to claim 1, wherein the controller is configured to:
-
capture biometric information of the at least one further user based on the signal output from the at least one sensor, and determine if the captured biometric information corresponds to biometric information stored in a memory coupled to the controller; wherein if the captured biometric information corresponds to biometric information stored in said memory, the controller further configured to retrieve lighting preferences associated with the biometric information stored in said memory to determine lighting preferences of the at least one further user; wherein if the captured biometric information does not correspond to biometric information stored in said memory, the controller further configured to retrieve default lighting preferences stored in said memory to determine lighting preferences of the at least one further user.

-
12. The controller according to claim 1, wherein the lighting preferences of the user comprise one or any combination of the user'"'"'s preferred lighting brightness, lighting color, spread of light incident in the user'"'"'s field of view, and light source type;
- and the lighting preferences of the at least one further user comprise one or any combination of the at least one further user'"'"'s preferred lighting brightness, lighting color, spread of light incident in the at least one further user'"'"'s field of view, and light source type.
-
13. The controller according to claim 1, wherein the controller is configured to execute an image recognition algorithm to detect an orientation of the user'"'"'s head to detect the orientation of the user and to detect an orientation of the least one further user'"'"'s head to detect the orientation of the least one further user.
-
14. A lighting system comprising the controller of claim 1, the one or more light source and the at least one sensor.
-
15. A computer program product for performing sensing using a signal output from at least one sensor to control one or more lighting source to illuminate an environment, the computer program product comprising code embodied on a computer-readable medium and configured so as when executed on one or more processing units to perform operations of:
-
identifying presence of a user and at least one further user in said environment based on the signal output from the at least one sensor; determining lighting preferences of the user and the at least one further user; detecting an orientation of the user and the at least one further user based on the signal output from the at least one sensor; estimating a field of view of the user and the at least one further user based on the detected orientation of the user and the at least one further user; determining that at least one light source of the one or more light source is positioned to emit light in both the field of view of said user and the field of view of said at least one further user, arbitrate between the lighting preferences of the user and the at least one further user to determine light settings to be applied to the at least one light source, and controlling said at least one light source based on the determined light settings.
