Abstract

A user interface, a method, and a computer program product are provided for enabling a user to voice control over at least one setting of an apparatus such as a lighting system. The user interface determines a characteristic of an audio signal converted from vocal input of a user. A first setting of the apparatus is adjusted proportionally to a variation in the characteristic. Another setting of the apparatus may be adjusted on the basis of another characteristic of the audio signal. As a result, the user interface enables the user to control a lighting system over a substantially large or continuous range of output.

Claims

1. A user interface for providing an output signal, said output signal adapted to control an apparatus, said user interface comprising:

an audio processor configured to determine a variation in a first characteristic of an audio signal that is received from an acoustic sensor, wherein said audio signal is representative of an acoustic input produced by a user and wherein the variation is within a portion of a substantially continuous range of values of the first characteristic; and

a controller configured to generate the output signal wherein the output signal is varied with substantially continuous range of values of the output signal for controlling the apparatus, and wherein the variation in the output signal is proportionally to the variation in the first characteristic.

2. The user interface according to claim 1, wherein the audio processor is further configured for processing the audio signal to derive a second characteristic of the audio signal.

3. The user interface according to claim 1, wherein said variation in the first characteristic of the audio signal is related to a temporal change in a frequency component of the audio signal.

4. The user interface according to claim 1, wherein said variation in the first characteristic of the audio signal is related to a change in a duration of a frequency component and/or an amplitude component of the audio signal being maintained over a period of time.

5. The user interface according to claim 1, wherein:

said audio processor is further configured to process the audio signal to determine whether the audio signal meets a trigger criterion; and

said controller is configured to generate the output signal in response to determining that the audio signal meets the trigger criterion.

6. The user interface according to claim 2, wherein said controller is further configured to generate the output signal in accordance with a variation in the second characteristic.

7. The user interface according to claim 2, wherein said controller is further configured to adapt the output signal and/or generate another output signal on the basis of at least one of the first characteristic and the second characteristic.

8. The user interface according to claim 1, wherein the output signal is adapted to control at least one setting of the apparatus, the apparatus being a lighting apparatus, and said at least one setting comprising at least one of:

a color setting, a hue setting, a saturation setting, a color temperature setting, an intensity setting, spectral setting, directionality setting, and angular distribution setting.

9. A system comprising at least one of a lighting apparatus and a sound apparatus, wherein either or both apparatus are controllable by a user interface according to claim 1.

16. The user interface according to claim 1, wherein said variation in the first characteristic of the audio signal is related to a temporal change in an amplitude component of the audio signal.

10. A method for providing an output signal for controlling an apparatus, said method comprising:

processing an audio signal that is received from an acoustic sensor, to determine a variation in a first characteristic of the audio signal, wherein said audio signal is representative of an acoustic input from a use and wherein the variation is within a portion of a substantially continuous range of values of the characteristic; and

generating the output signal, wherein the output signal is varied within a substantially continuous range of values of the output signal for controlling the apparatus, and wherein the variation in the output signal is proportionally to the variation in the first characteristic;

11. The method according to claim 10, further comprising adjusting a setting of the apparatus using the output signal.

12. The method according to claim 10, further comprising processing the audio signal to derive a second characteristic of the audio signal.

15. A computer program product, implemented on computer-readable non-transitory storage medium, the computer program product configured for, when run on a computing device, executing the method according to claim 10.

13. The method according to claim 13, further comprising generating the output signal on the basis of the second characteristic.

14. The method according to claim 13, further comprising adapting the output signal and/or generating another output signal on the basis of at least one of the first characteristic and the second characteristic.
