Abstract

In one embodiment, a method includes sending information to display a visual content; determining a scroll range for the visual content based on dimensions of the visual content; determining an origin position within the visual content from which the visual content is configured to be scrolled, wherein the origin position is determined based on a type of an application associated with the visual content; receiving an initial tilt measurement of a client computing device; receiving a second tilt measurement of the client computing device; determining a progress parameter based on at least the scroll range, the origin position, the initial tilt measurement, and the second tilt measurement; and sending information to scroll the visual content based on the progress parameter.

Claims

1. A method comprising:

by a computing device, sending information to display a visual content item;

by the computing device, determining a scroll range for the visual content item based on one or more dimensions of the visual content item;

by the computing device, determining an origin position within the visual content item, wherein the origin position is an initial position in the visual content item from which the visual content item is to be scrolled, and wherein the origin position is determined based on a type of an application associated with the visual content item;

by the computing device, receiving an initial tilt measurement of a client computing device;

by the computing device, receiving a second tilt measurement of the client computing device;

by the computing device, determining a progress parameter based on at least the scroll range, the origin position, the initial tilt measurement, and the second tilt measurement; and

by the computing device, sending information to scroll the visual content item based on the progress parameter.

2. The method of claim 1, wherein a threshold for activating scrolling is satisfied by the tilt measurements.

3. The method of claim 1, wherein a threshold for activating scrolling is satisfied by a rotation rate that is calculated based on a delta between the initial tilt measurement and the second tilt measurement.

4. The method of claim 1, further comprising applying a RK4 (Runge-Kutta) solver to the tilt measurements to eliminate noise.

5. The method of claim 1, further comprising applying a virtual spring effect to the visual content item in relation to the origin position.

6. The method of claim 5, wherein the virtual spring effect causes the scrolling of the visual content item to appear to bounce when a limit of the scroll range is reached.

7. The method of claim 5, wherein the virtual spring effect causes the scrolling of the visual content item to appear to slow down as a limit of the scroll range is approached.

8. The method of claim 1, further comprising:

receiving input to re-calibrate the origin position; and

determining a new origin position based on the input.

9. The method of claim 1, wherein the tilt measurements are based upon motion captured by a gyroscope with respect to a single axis planar with respect to a presentation of the visual content item.

10. The method of claim 1, wherein the tilt measurements are based upon motion captured by a gyroscope with respect to two axes orthogonal with respect to each other, both of which are planar with respect to a presentation of the visual content item.

11. The method of claim 1, wherein the visual content item comprises a photo, a number of photos represented as a photo album, a list, a web page, a map, a visual representation of a library of items, a video game, or a technical diagram.

12. The method of claim 1, further comprising sending a visual hint indicating that scrolling may be performed on the visual content item.

13. The method of claim 12, wherein the visual hint further indicates one or more directions in which scrolling is possible.

14. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

send information to display a visual content item;

determine a scroll range for the visual content item based on one or more dimensions of the visual content item;

determine an origin position within the visual content item, wherein the origin position is an initial position in the visual content item from which the visual content item is to be scrolled, and wherein the origin position is determined based on a type of an application associated with the visual content item;

receive an initial tilt measurement of a client computing device;

receive a second tilt measurement of the client computing device;

determine a progress parameter based on at least the scroll range, the origin position, the initial tilt measurement, and the second tilt measurement; and

send information to scroll the visual content item based on the progress parameter.

15. The media of claim 14, wherein the tilt measurements are based upon motion captured by a gyroscope with respect to a single axis planar with respect to a presentation of the visual content item.

16. The media of claim 14, wherein the tilt measurements are based upon motion captured by a gyroscope with respect to two axes orthogonal with respect to each other, both of which are planar with respect to a presentation of the visual content item.

21. The media of claim 14, wherein a threshold for activating scrolling is satisfied by the tilt measurements.

22. The media of claim 14, wherein a threshold for activating scrolling is satisfied by a rotation rate that is calculated based on a delta between the initial tilt measurement and the second tilt measurement.

23. The media of claim 14, further comprising applying a RK4 (Runge-Kutta) solver to the tilt measurements to eliminate noise.

24. The media of claim 14, further comprising applying a virtual spring effect to the visual content item in relation to the origin position.

25. The media of claim 24, wherein the virtual spring effect causes the scrolling of the visual content item to appear to bounce when a limit of the scroll range is reached.

26. The media of claim 24, wherein the virtual spring effect causes the scrolling of the visual content item to appear to slow down as a limit of the scroll range is approached.

27. The media of claim 14, further comprising:

receiving input to re-calibrate the origin position; and

determining a new origin position based on the input.

28. The media of claim 14, wherein the visual content item comprises a photo, a number of photos represented as a photo album, a list, a web page, a map, a visual representation of a library of items, a video game, or a technical diagram.

29. The media of claim 14, further comprising sending a visual hint indicating that scrolling may be performed on the visual content item.

30. The media of claim 29, wherein the visual hint further indicates one or more directions in which scrolling is possible.

17. A system comprising:

one or more processors; and

a memory coupled to the processors comprising instructions executable by the processors, the processors being operable when executing the instructions to;

send information to display a visual content item;

determine a scroll range for the visual content item based on one or more dimensions of the visual content item;

determine an origin position within the visual content item, wherein the orgin position is an initial position in the visual content item from which the visual content item is to be scrolled, and wherein the origin position is determined based on a type of an application associated with the visual content item;

receive an initial tilt measurement of a client computing device;

receive a second tilt measurement of the client computing device;

determine a progress parameter based on at least the scroll range, the origin position, the initial tilt measurement, and the second tilt measurement; and

send information to scroll the visual content item based on the progress parameter.

18. The system of claim 17, wherein the processors are further operable when executing the instructions to apply a virtual spring effect to the visual content item in relation to the origin position.

19. The system of claim 18, wherein the virtual spring effect causes the scrolling of the visual content item to appear to bounce when a limit of the scroll range is reached.

20. The system of claim 18, wherein the virtual spring effect causes the scrolling of the visual content item to appear to slow down as a limit of the scroll range is approached.
