Combining real imagery with computer generated imagery
[attachment=25973]
Virtual image of real data
3D sensed data can be studied for surgical paths to be followed by a surgeon or a robot.
In the future, real-time sensing and registration can be used for feedback in the process.
Difficult augmentation problem
How does computer system know where to place the graphic overlay?
Human very sensitive to misregistration
Some applications OK – such as circuit board inspection.
Can use trackers on HMD to give approximate head pose
Tough calibration procedures for individuals (see Charles Owens’ work)
Summary of issues
All systems (VR,AR,TO) require sensing of human actions or robot actions
All systems need models of objects or the environment
Difficult registration accuracy problem for AR, especially for see-through displays, where the fusion is done in the human’s visual system
