Abstract

A light effect control method, computer program product and device are presented which allow an application to render a light effect by a networked lighting system based on the method, computer program product or device receiving an event being from the application. To provide a better user experience, light effects related to certain events need to be rendered even if a delay in rendering is expected whereas light effects related to other events need to be rendered without delay or else not rendered at all. As such, a decision is made to execute a first or a second scenario based on the event type of the event received and/or the capacity of the networked lighting system, wherein in the first scenario the lighting control command is always sent to the networked lighting system and in the second scenario the lighting control command is only sent to the networked lighting system if no unacceptable delay in rendering the light effect is expected.

Claims

1. A computer implemented method for allowing an application to render a light effect via a networked lighting system, the method comprising:

receiving an event from the application, the event related to a light effect for being rendered by the networked lighting system,

determining an event type, from a set of event types, of the event received, wherein the set of event types comprises at least a first event type and a second event type,

determining a capacity of the networked lighting system for executing a lighting control command,

selecting for execution a scenario from a set of scenarios based on the determined capacity of the networked lighting system and the determined event type, wherein the set of scenarios comprises at least a first and a second scenario, and

executing the selected scenario,

wherein the first scenario comprises sending one or more lighting control commands for rendering the light effect related to the event received to the networked lighting system, and the second scenario comprises dismissing the event received by not sending a lighting control command to the networked lighting system.

2. The computer implemented method of claim 1, wherein the set of scenarios further comprises a third scenario comprising:

determining an approximate light effect based on the light effect related to the event received, and

sending one or more lighting control commands, for rendering the approximate light effect, to the networked lighting system.

3. The computer implemented method of claim 2, wherein the number of lighting control commands required to render the light effect related to the event received is greater than the number of lighting control commands required to render the approximate light effect.

4. The computer implemented method claim 2, wherein the number of lighting devices required to render the approximate light effect is smaller than the number of lighting devices required to render the light effect related to the event received.

5. The computer implemented method of claim 1, wherein determining the capacity of the networked lighting system is based on a predetermined value indicative of an expected number of lighting control commands for which the networked lighting system has capacity.

6. The computer implemented method of claim 1, wherein determining the capacity of the networked lighting system is based on a first predetermined value indicative of an expected number of lighting control commands of a first type for which the networked lighting system has capacity and a second predetermined value indicative of an expected number of lighting control commands of a second type for which the networked lighting system has capacity.

7. The computer implemented method of claim 1, wherein determining the capacity of the networked lighting system is based on a number of lighting control commands stored in a buffer of a device in the networked lighting system.

8. The computer implemented method of claim 1, wherein determining the capacity of the networked lighting system is based on measuring the amount of network traffic present in the networked lighting system.

9. The computer implemented method of claim 1, wherein the first scenario is executed when the event received is of the first event type,

wherein the first event type relates to a light effect for which successful rendering by the networked lighting system is of high importance.

10. The computer implemented method of claim 1, wherein the second scenario is executed when the event received is of the second event type, and the determined capacity of the networked lighting system is indicative of an expected delay, above a predetermined threshold, in rendering the light effect related to the event received,

wherein the second event type relates to a light effect for which timely rendering by the networked lighting system is of high importance.

11. The computer implemented method of claim 9, wherein the light effect for which successful rendering by the networked lighting system is of high importance relates to a lighting scene change based on a virtual character moving, in a virtual environment provided by the application, from a first location to a second location, and

wherein the first location is related to a first lighting scene and the second location is related to a second lighting scene different from the first lighting scene.

12. The computer implemented method of claim 9, wherein the light effect for which timely rendering by the networked lighting system is of high importance relates to a lighting feedback triggered by an event occurring in a virtual environment provided by the application.

13. The computer implemented method of claim 1, wherein the networked lighting system comprises one or more lighting devices arranged for receiving lighting control commands over a mesh network, and wherein sending a lighting control command, for rendering the light effect related to the event received, comprises sending a message over the mesh network.

14. A computer program product comprising program code for causing a computer to carry out the method of claim 1, when the computer program product is carried out on the computer.

15. A networked lighting system control device for controlling a networked lighting system, the networked lighting system control device comprising:

an input arranged for receiving an event related to a light effect for being rendered by the networked lighting system,

a network interface arranged for sending a lighting control command to the networked lighting system, and

a processor operationally coupled to the input and the network interface, wherein the processor is arranged for;

determining an event type, from a set of event types, of the event received, wherein the set of event types comprises at least a first event type and a second event type,

determining a capacity of the networked lighting system for executing a lighting control command,

selecting for execution a scenario from a set of scenarios based on the determined capacity of the networked lighting system and the determined event type, wherein the set of scenarios comprises at least a first and a second scenario, and

executing the selected scenario,

wherein the first scenario comprises sending a lighting control command for rendering the light effect related to the event received to the networked lighting system, and the second scenario comprises dismissing the event received by not sending a lighting control command to the networked lighting system.
