Abstract

A display application rotates content to provide a perspective view along the z-axis during a scroll action as a feedback to a user indicating a scroll action has reached a beginning or an end of available content. Determined direction and speed and/or acceleration of the scroll action is applied to move content and rotate it based on: a tilt angle proportional to the speed and/or acceleration and a rotation axis perpendicular to the direction. Additional content is displayed in the perspective view based on the tilt angle. And, the tilt angle is adjusted to rotate the content in response to reaching an end of the content during the scroll action or upon detecting a subsequent scroll action.

Claims

1. A method executed on a computing device for providing a rotation of a content during a scroll action, the method comprising:

displaying the content;

detecting the scroll action from a captured gesture interacting with the content;

determining a direction and one of a speed and an acceleration of the scroll action;

moving the content based on the speed in the direction of the scroll action;

rotating the content on a rotation axis perpendicular to the direction based on a tilt angle in proportion to the speed of the scroll action, wherein the proportion between the tilt angle and the speed of the scroll action during the rotation of the content determines a depth of a perspective view along a z-axis; and

in response to reaching an end of the content, adjusting the tilt angle of the content in proportion to the one of the speed and acceleration of the scroll action.

2. The method of claim 1, further comprising:

retrieving a sample frequency for measurements of the direction based on at least one of;

a predetermined system setting and a user adjustable value; and

determining the direction based on an average of sampled measurements of the direction of the scroll action measured based on the sample frequency.

3. The method of claim 1, further comprising:

retrieving a sample frequency for measurements of the speed based on at least one of;

a predetermined system setting and a user adjustable value; and

determining the speed based on an average of sampled measurements of the speed of the scroll action measured based on the sample frequency.

4. The method of claim 1, further comprising:

interpreting the scroll action to move in the direction on one of;

an x-axis and a y-axis in response to detecting the direction having the tilt angle other than about 0 degrees, about 90 degrees, about 180 degrees, and about 270 degrees.

5. The method of claim 4, further comprising:

selecting the x-axis as the rotation axis in response to the direction being less than a 45 degree tilt angle from the y-axis.

6. The method of claim 4, further comprising:

selecting the y-axis as the rotation axis in response to the direction being less than a 45 degree tilt angle from the x-axis.

7. The method of claim 4, further comprising:

selecting one of;

the x-axis and the y-axis as the rotation axis in response to the direction being at a 45 degree tilt angle from one of;

the x-axis and the y-axis based on at least one of;

a predetermined system setting and a user preference.

8. The method of claim 1, further comprising:

selecting an x-axis as the rotation axis in response to determining the direction having the tilt angle including one of;

about 0 degrees and about 180 degrees; and

selecting a y-axis as the rotation axis in response to determining the direction having the tilt angle including one of;

about 90 degrees and about 270 degrees.

9. The method of claim 1, further comprising:

determining a rotation point at an edge of a display surface of the computing device opposite another edge on a path of the direction of the scroll action.

10. The method of claim 1, further comprising:

determining a rotation point based on one of;

a content entry location on to a display surface of the computing device, and

at least one of;

a predetermined system setting and a user configurable setting at a location on the display surface of the computing device.

11. A computing device for providing a rotation of a content during a scroll action, the computing device comprising:

a memory configured to store instructions; and

a processor coupled to the memory, the processor executing a display application in conjunction with the instructions stored in the memory, wherein the display application is configured to;

display the content;

detect the scroll action from a captured gesture interacting with the content;

retrieve a first sample frequency for measurements of a direction and a second sample frequency for measurements of a speed based on at least one of;

predetermined system settings and user adjustable values;

determine the direction based on an average of sampled measurements of the direction of the scroll action measured based on the first sample frequency;

determine the speed based on an average of sampled measurements of the speed measurements of the scroll action measured based on the second sample frequency;

move the content based on the speed in the direction of the scroll action;

determine a rotation point at an edge of a display surface of the computing device, opposite another edge, on a path of the direction of the scroll action;

rotate the content on the rotation point and on a rotation axis perpendicular to the direction based on a tilt angle in proportion to the speed of the scroll action, wherein the proportion between the tilt angle and the speed of the scroll action during the rotation of the content determines a depth of a perspective view along a z-axis; and

in response to reaching an end of the content, adjust the tilt angle of the content in proportion to the speed of the scroll action.

12. The computing device of claim 11, wherein the application is further configured to:

display additional content in the perspective view along the z-axis in proportion to the tilt angle while rotating the content.

not detecting another scroll action and reaching the end of the content.

16. The computing device of claim 11, wherein the application is further configured to:
