Abstract

An embodiment provides a method, including: scrolling content rendered in a display device at a first positive speed; receiving, at an optical sensor, image information of a user of an information handling device; determining, using a processor, a focal point of user gaze with respect to the content rendered in the display device, the focal point being derived from the image information; associating the focal point with a target of the display device; adjusting the first positive speed for scrolling of the rendered content to a non-negative second speed based on the associating. Other aspects are described and claimed.

Claims

1. An information handling device, comprising:

an optical sensor;

a display device;

a processor; and

a memory device storing instructions executable by the processor to;

scroll content rendered in the display device at a first positive speed;

receive, at the optical sensor, image information of a user of an information handling device;

determine a focal point of user gaze with respect to the content rendered in the display device, the focal point being derived from the image information;

associate the focal point with a target of the display device;

adjust the first positive speed for scrolling of the rendered content to a non-negative second speed based on the associating; and

activate a second target.

2. A method, comprising:

scrolling content rendered in a display device at a first positive speed;

receiving, at an optical sensor, image information of a user of an information handling device;

determining, using a processor, a focal point of user gaze with respect to the content rendered in the display device, the focal point being derived from the image information;

associating the focal point with a target of the display device;

adjusting the first positive speed for scrolling of the rendered content to a non-negative second speed based on the associating; and

activating a second target.

3. The method of claim 2, further comprising determining a distance between the focal point and the target.

4. The method of claim 3, wherein the adjusting is proportional to the distance.

5. The method of claim 3, wherein the activating is triggered based on the distance.

6. The method of claim 2, wherein the target and the second target are both maintained and utilized for the adjusting.

7. The method of claim 2, wherein the target is replaced by the second target following activation of the second target.

8. The method of claim 2, wherein the non-negative second speed is larger than the first positive speed and results in an increased downward scrolling speed.

9. The method of claim 2, wherein the target comprises a horizontal sub area of the display.

10. The method of claim 9, wherein the target is not displayed in the display device.

11. The method of claim 9, wherein the target is located in an upper third of the display device.

12. The method of claim 11, wherein the second target is located in a lower third of the display device.

13. The method of claim 12, wherein:

the target and the second target bound a middle area of the display device; and

smooth scrolling is implemented via the adjusting based on a distance between a current focal point of the user and one or more of the target and the second target.

14. The method of claim 2, wherein scrolling initially proceeds at a default rate determined via a factor selected from the group of factors consisting of a type of content rendered, an application used to render the content, a user selection, a user history, and a device characteristic.

15. A method, comprising:

scrolling content rendered in a display device at a first positive speed;

receiving, at an optical sensor, image information of a user of an information handling device;

determining, using a processor, a focal point of user gaze with respect to the content rendered in the display device, the focal point being derived from the image information; and

adjusting the first positive speed for scrolling of the rendered content to a non-negative second speed based on the focal point of user gaze within the content rendered in the display device;

wherein the non-negative second speed is zero when the focal point exceeds a predetermined distance from a target.

16. The method of claim 15, wherein the non-negative second speed is larger than the first positive speed and results in an increased downward scrolling speed.

17. The method of claim 15, further comprising:

associating the focal point with the target of the display device; and

determining a distance between the focal point and the target;

wherein the adjusting is proportional to the distance.

18. The method of claim 15, wherein scrolling initially proceeds at a default rate determined via a factor selected from the group of factors consisting of a type of content rendered, an application used to render the content, a user selection, a user history, and a device characteristic.

19. The method of claim 15, wherein the adjusting is modified based on a factor selected from the group of factors consisting of a type of content rendered, an application used to render the content, a user selection, a user history, and a device characteristic.

20. The method of claim 19, wherein the type of content rendered is determined via an analysis of the content data.
