Providing content rotation during scroll action

摘要

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.

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.
