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 an intensity of light emitted by the at least one light source based on a speed of typing into the keyboard,

the controller being configured to cause the intensity of the light, when an application identified as a productivity application is running on a computing system receiving input from the keyboard, to be higher than the intensity of the light when a leisure application is running on the computing system,

the productivity application including at least one of a word processing application, a spreadsheet application, or a presentation application,

the leisure application including at least one of a music player, a video player, a gaming application, or a web browser.

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 a 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 control 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.

6. 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 being logged into a personal account; and

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

7. The keyboard of claim 6, wherein the keyboard is configured to reduce an intensity of the light source based on the user being logged into the personal account.

8. The keyboard of claim 1, wherein the controller is configured to decrease the intensity based on a user typing the keys at a fast speed.

9. The keyboard of claim 1, wherein the controller is configured to increase the intensity based on a user typing the keys at a slow speed.

10. The keyboard of claim 1, wherein:

the controller is configured to decrease the intensity based on a user typing the keys at a fast speed; and

the controller is configured to increase the intensity based on the user typing the keys at a slow speed.

11. The keyboard of claim 1, wherein the productivity application includes the word processing application.

12. The keyboard of claim 1, wherein the productivity application includes the spreadsheet application.

13. The keyboard of claim 1, wherein the productivity application includes the presentation application.

14. The keyboard of claim 1, wherein the leisure application includes the music player.

15. The keyboard of claim 1, wherein the leisure application includes the video player.

16. The keyboard of claim 1, wherein the leisure application includes the gaming application.

17. The keyboard of claim 1, wherein the leisure application includes the web browser.

18. 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 an intensity of light emitted by the at least one light source based on a speed of typing into the keyboard,

the controller being configured to cause a color of the light, when a productivity application is running on a computing system receiving input from the keyboard, to have greater contributions from colors other than blue than when a leisure application is running on the computing system,

the productivity application including at least one of a word processing application, a spreadsheet application, or a presentation application,

the leisure application including at least one of a music player, a video player, a gaming application, or a web browser.

19. The keyboard of claim 18, wherein the productivity application includes the word processing application.

20. The keyboard of claim 18, wherein the leisure application includes the web browser.
