Method And System For Automatically Associating A Cursor with A Hotspot In A Hypervideo Stream Using A Visual Indicator

Abstract

Methods and systems are described for automatically linking a cursor to a hotspot in a hypervideo stream comprising a plurality of video frames that are associated with at least one user selectable hotspot. One method includes receiving information associating a cursor with a selectable hotspot in a first activation region of a first video frame received for presentation in a video presentation space. A second video frame including the selectable hotspot in a second activation region different from the first activation region is received for presentation in the video presentation space. The second video frame is presented with a visual indicator associating the cursor with the second activation region if the cursor is outside of the second activation region.
