Abstract

Examples relate to changing screen brightness of a computing device. One example enables determination of whether the computing device is being used for one of a set of predetermined application types. The screen brightness of the computing device may be changed based on a set of first brightness values associated with the first predetermined application type responsive to the computing device being used for a first predetermined application type and based on a set of second brightness values associated with the second predetermined application type responsive to the computing device being used for a second predetermined application type.

Claims

1. A system for changing screen brightness of a computing device, the system comprising:

a usage determination engine to;

determine an application being displayed on a screen of the computing device; and

compare the determined application to a set of predetermined application types to determine whether a brightness changing condition has been met; and

a brightness adjustment engine to;

change the screen brightness of the computing device to a first single brightness value associated with a first predetermined application type of the set of predetermined application type when the determined application is the first predetermined application type; and

change the screen brightness of the computing device based on a second single brightness value associated with a second predetermined application type of the set of predetermined application type when the determined application is the second predetermined application type.

2. The system of claim 1, further comprising:

a brightness learning engine to determine the first and second brightness values based on first and second predetermined application types.

3. The system of claim 2, further comprising:

a camera to monitor pupil dilation of a user of the computing device,

wherein the brightness learning engine is to determine the first and second brightness values based on the monitored pupil dilation of the user.

4. The system of claim 2, wherein the brightness learning engine is to determine the first and second brightness values based on a determined ambient light value and the first predetermined application type.

5. The system of claim 1, further comprising:

an application type selection engine to add a new application type to the predetermined application types responsive to usage of the computing device.

6. A system for changing screen brightness of a computing device, the system comprising:

a LED determination engine to determine whether a first LED device is being used in the proximity of the computing device by determining whether an API associated with the first LED device is being accessed at the computing device;

a brightness adjustment engine to;

change the screen brightness of the computing device based on a set of first LED brightness values associated with the first LED device and a determined ambient light value in response to a determination that the first LED device is being used in the proximity of the computing device.

7. The system of claim 6, further comprising:

a brightness learning engine to determine the set of first LED brightness values associated with the first LED device.

8. The system of claim 7, further comprising:

a camera to monitor pupil dilation of a user of the computing device,

wherein the brightness learning engine is to determine the set of first LED brightness values based on the monitored pupil dilation of the user and a determined brightness value of the first LED device.

9. The system of claim 7, wherein the brightness learning engine is to determine the set of first brightness values by determining an optimal brightness curve associated with the first LED device based on a determined ambient light value and a determined brightness value of the first LED device.

10. The system of claim 6, wherein the brightness adjustment engine is to change the screen brightness of the computing device based on the set of first LED brightness values associated with the first LED device and a set of second LED brightness values associated with a second LED device responsive to the first LED device and the second LED device being used in the proximity of the computing device.

11. A method for changing screen brightness of a computing device, comprising:

Determining, at the computing device, an application being displayed on a screen of the computing device;

Comparing, at the computing device, the determined application to a set of predetermined application types to determine whether a brightness changing condition has been met;

responsive to the determined application being a first predetermined application type, changing the screen brightness of the computing device to a first single brightness value associated with the first predetermined application type;

responsive to the determined application being a second predetermined application type, changing the screen brightness of the computing device to a second single brightness value associated with the second predetermined application type;

determining whether a first LED device is being used in the proximity of the computing device by determining whether an API associated with the first LED device is being accessed at the computing device; and

responsive to a first LED device being used in the proximity of the computing device, changing the screen brightness of the computing device based on a set of first LED brightness values associated with the first LED device and a determined ambient light value.

12. The method of claim 11, further comprising:

monitoring, by a camera communicably coupled to the computing device, pupil dilation of a user of the computing device; and

determining the set of first brightness values based on the monitored pupil dilation of the user.

13. The method of claim 12, further comprising:

determining the set of first brightness values by determining an optimal brightness curve for the predetermined application type based on a determined ambient light value and the first predetermined application type.

14. The method of claim 12, further comprising:

determining the set of first LED brightness values based on the monitored pupil dilation of the user and a determined brightness value of the first LED device.

15. The method of claim 11, further comprising:

changing the screen brightness of the computing device further based on time of usage, current location of the computing device, and/or a user of the computing device.
