DRAGONEye

DRAGONEye is a new version of DRAGON, our direct-manipulation interaction technique for frame-accurate navigation in video scenes. Through the use of a novel object tracking algorithm, we could get rid of the substantial pre-processing time that DRAGON required. At the same time, DRAGONEye is more robust to object occlusions.

DRAGONEye is a research project by Moritz Wittenhagen, Thorsten Karrer, Malte Weiss, Jan Borchers and others at the Media Computing Group. It is funded in part through the German B-IT Foundation, the UMIC DFG Excellence Initiative, and the HumTec Human Technology Center.

DRAGON is our original direct-manipulation interaction technique for frame-accurate navigation in video scenes.
PocketDRAGON is an implementation of the DRAGON technique for the iPhone. It helps to navigate videos without wasting any valuable screen real estate on the mobile device.
