Abstract

A keyboard may include a plurality of keys, at least one light source configured to illuminate the plurality of keys, and a controller. The controller may be configured to control a color and/or an intensity of light emitted by the at least one light source based on a time of day and/or a type of an application running on a computing system receiving input from the keyboard.

Claims

1. A keyboard comprising:

a plurality of keys;

at least one light source configured to illuminate the plurality of keys; and

a controller configured to control a color and/or an intensity of light emitted by the at least one light source based on a time of day and/or a type of an application running on a computing system receiving input from the keyboard.

2. The keyboard of claim 1, wherein the controller is configured to process at least one signal to determine that a user is likely to go to sleep soon and control the at least one light source based on the at least one signal.

3. The keyboard of claim 1, wherein the controller is configured to cause the intensity of the light during hours identified as working hours to be higher than the intensity of the light during hours identified as evening hours.

4. The keyboard of claim 1, wherein the controller is configured to cause the color of the light during hours identified as working hours to have greater contributions from colors other than blue than during evening hours.

5. The keyboard of claim 1, wherein the controller is configured to cause the intensity of the light when an application identified as a productivity type application is running on the computing system to be higher than the intensity of the light when a leisure application is running on the computing system.

6. The keyboard of claim 1, wherein the controller is configured to cause the color of the light when a productivity application is running on the computing system to have greater contributions from colors other than blue than when a leisure application is running on the computing system.

7. The keyboard of claim 1, wherein the controller is configured to control the color and/or the intensity of the light based on a user profile associated with a user of the keyboard, the user profile indicating a predicted time duration before the user goes to sleep.

8. The keyboard of claim 1, wherein the controller is configured to:

reduce contributions from colors other than blue by the light source based on a user account being a personal account; and

increase contributions from colors other than blue by the light source based on a user account being a work account.

9. The keyboard of claim 1, wherein the controller is configured to control the color and the intensity of the light based on a typing pattern of a user of the keyboard.

10. The keyboard of claim 1, wherein the controller is configured to control the color and the intensity of the light based on a frequency of input into the keyboard over a predetermined time period.

11. A keyboard comprising:

at least a first key and a second key;

at least a first light source configured to illuminate the first key and a second light source configured to illuminate the second key; and

a controller configured to cause an intensity of light emitted by the first light source to be greater than an intensity of light emitted by the second light source based on an application running on a computing system receiving input from the keyboard.

12. The keyboard of claim 11, wherein the application includes an application for learning to type.

13. The keyboard of claim 11, wherein the controller is configured to cause the first light source to have a greater intensity of emitted light than the second light source based on a prediction that the first key is more likely to receive input than the second key.

14. The keyboard of claim 11, wherein the controller is configured to cause the first light source to have a greater intensity of emitted light than the second light source based on receiving input into the first key more recently than the second key.

15. A method comprising:

determining, by a computing system, a time of day and/or determining a type of application running on the computing system;

determining, based on the time of day and/or the type of application running on the computing system, that a user of the computing system is likely to go to sleep soon;

reducing an intensity of a light source for a keyboard based on the determining that the user is likely to go to sleep soon; and

/or

reducing contributions of colors, other than blue, by the light source for the keyboard based on the determining that the user is likely to go to sleep soon.

16. The method of claim 15, further comprising:

processing at least one signal to determine that the user is likely to go to sleep soon; and

controlling the at least one light source based on the at least one signal.

17. The method of claim 15, wherein the determining that the user is likely to go to sleep soon is based on the time of day transitioning from working hours to evening hours.

18. The method of claim 15, wherein the determining that the user is likely to go to sleep soon is based on the type of application running on the computing system being a leisure application.

19. The method of claim 15, wherein the determining that the user is likely to go to sleep soon is based on an indication, by a user profile associated with an account logged into the computing system, that the user is likely to go to sleep soon after the determined time of day.

20. The method of claim 15, further comprising:

determining that a user account logged into the computing system is a personal account,

wherein the determining that the user of the computing system is likely to go to sleep soon is based on the time of day, the type of application running on the computing system, and the user account being the personal account.

21. The method of claim 15, further comprising:

determining a typing pattern of input into the keyboard,

wherein the determining that the user of the computing system is likely to go to sleep soon is based on the time of day, the type of application running on the computing system, and the typing pattern.

22. The method of claim 15, further comprising:

determining a frequency of input into the keyboard over a predetermined time period,

wherein the determining that the user of the computing system is likely to go to sleep soon is based on the time of day, the type of application running on the computing system, and the frequency of input into the keyboard.
