Abstract

In one embodiment, a method includes determining, by a computing device, a scroll range for an image based on a dimension of the image, determining the image'"'"'s origin position device'"'"'s initial tilt, determining a second tilt and a rate of rotation about a first axis, and determining a rate of rotation about a second axis. The method includes comparing the device'"'"'s rate of rotation about the first axis with the device'"'"'s rate of rotation about the second axis or one of its components. The method further includes determining, based on the comparison, whether to render a scrolling presentation of the image. When the scrolling presentation of the image is to be rendered, the method includes determining a progress parameter based on the scroll range, the origin position, the initial tilt, and the second tilt; and rendering a scrolling presentation of the image based on the progress parameter.

by a computing device, determining a scroll range for an image for display on the device, the scroll range based at least in part on a dimension of the image;

by the computing device, determining an origin position of the image and an initial tilt of the device;

by the computing device, determining a second tilt and a rate of rotation about a first axis;

by the computing device, determining a rate of rotation about a second axis;

by the computing device, comparing the rate of rotation of the device about the first axis with the rate of rotation of the device about the second axis or about a component of the second axis;

by the computing device, determining, based on the comparison, whether to render a scrolling presentation of the image; and

by the computing device, when the scrolling presentation of the image is to be rendered;

determining a progress parameter based at least in part on the scroll range, the origin position, the initial tilt, and the second tilt; and

rendering a scrolling presentation of the image based at least in part on the progress parameter.

2. The method of claim 1, wherein the progress parameter is determined substantially concurrently with one or more of:

determining the rate of rotation about the second axis;

comparing the rate of rotation about the first axis with the rate of rotation about the second axis or about the component of the second axis;

or

determining, based on the comparison, whether to render the scrolling presentation of the image.

3. The method of claim 1, wherein one or both of:

the second axis;

or

the component of the second axis, is orthogonal to the first axis.

4. The method of claim 1, wherein comparing the rate of rotation of the device about the first axis with the rate of rotation of the device about the second axis or about the component of the second axis comprises determining a ratio of the rate of rotation about the second axis or about the component of the second axis to the rate of rotation about the first axis.

5. The method of claim 4, wherein determining, based on the comparison, whether to render the scrolling presentation of the image comprises:

comparing the ratio to a predetermined ratio; and

when the ratio is greater than the predetermined ratio, determining that the scrolling presentation should not be rendered.

6. The method of claim 5, wherein the predetermined ratio has a value of approximately 0.55.

7. The method of claim 1, wherein the first axis comprises an axis in the plane of the image and orthogonal to a third axis along which the image has a nonzero scroll range.

8. The method of claim 7, wherein the second axis is the third axis.

9. The method of claim 1, wherein the scroll range depends on the orientation of the device.

10. The method of claim 1, wherein determining, based on the comparison, whether to render the scrolling presentation of the image comprises determining whether to render the scrolling presentation of the image based on:

the comparison; and
