Method and system for automatically linking a cursor to a hotspot in a hypervideo stream

摘要

Automatically linking a cursor to a hotspot in a hypervideo stream comprising a plurality of video frames that are associated with at least one selectable hotspot include receiving a hypervideo stream of a first video frame associated with a selectable hotspot in a first activiation region of the first video frame, and determining whether a first position of a cursor is substantially within the first activiation region corresponding to the selectable hotspot. The cursor is associated with the selectable hotspot when the first position of the cursor is substantially within the first activiation region corresponding to the selectable hotspot in the first video frame. The hypervideo stream of a second video frame associated with the selectable hotspot in a second activation region different from the first activation region is received, and the cursor is automatically moved to a second position in the second video frame based on the association.

1. A method for automatically linking a cursor to a hotspot in a hypervideo stream, wherein the hypervideo stream comprises a plurality of video frames that are associated with at least one selectable hotspot, the method comprising:
receiving a hypervideo stream of a first video frame, the first video frame associated with a selectable hotspot in a first activation region of the first video frame; determining whether a first position of a cursor is substantially within the first activation region corresponding to the selectable hotspot; associating the cursor with the selectable hotspot when the first position of the cursor is substantially within the first activation region corresponding to the selectable hotspot in the first video frame; receiving the hypervideo stream of a second video frame, the second video frame associated with the selectable hotspot in a second activation region, wherein the second activation region is different from the first activation region; automatically moving the cursor to a second position substantially within the second activation region in the second video frame based on the association between the cursor and the selectable hotspot, wherein the second position is at a closest edge of the second activation region; receiving the hypervideo stream of a third video frame, wherein the selectable hotspot is not associated with the third video frame; maintaining the association between the cursor and the selectable hotspot for a second predetermined time period; and performing an action corresponding to the selectable hotspot when the selectable hotspot is activated within the second predetermined time period.
