Abstract: Aspects of this disclosure are directed to techniques that enable a computing device to provide a visual indication that there is no additional content to scroll. When a user continues to perform a scroll gesture and scrolls to the end of the content and attempts to continue to scroll the content (i.e., overscrolls the content), a computing device configured in accordance with the techniques of this disclosure may visually stretch at least a portion of the displayed content. In various instances, the computing device may determine various characteristics of the scroll gesture, such as location on a presence-sensitive screen of the computing device, velocity, acceleration, duration, etc. Based on one or more of these scroll gesture characteristics, the computing device may determine a stretch ratio and may apply the stretch ratio to at least a portion of the displayed content.
