Project Description

Objective	Approach and Plan	Progress and Next Steps
Disuss state of the art of "visual" AR for interventional radiology/surgery Find and prototype appropriate auditory display methods for efficient depth perception feedback Discover optimal mix between auditory and visual feedback methods for depth perception	Discussion about possibilties to support depth persception (visually and auditory) Implementation of new depth cues	Enabled kinetic depth cues for Needle Navigation Software: direct control of scene camera movement with head position tracking Sound connection could not be implemented during this week (had to rework parts the own code base first, took much time) Started to implement head tracking -> need some different hardware Next steps will further focus on head tracking and fusion with sonification
