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 establishing an association between a selectable hotspot in a first activation region of a first video frame received for presentation in a video presentation space and a cursor when a first position of the cursor is within the first activation region corresponding to the selectable hotspot. The method also includes receiving a second video frame that includes the selectable hotspot in a second activation region different from the first activation region, and determining whether a second position of the cursor is outside of the second activation region of the second video frame. Responsive to the determination, the second video frame is presented with a visual indicator associating the cursor with the selectable hotspot based on the association between the cursor and the selectable hotspot.
