What is active visualization?
Visualization is ultimately a psycho-physiological phenomenon and we can try to exploit this. Human vision is a very active process involving four principal eye movements: saccades, pursuit movements, vestibular systems and vergence [Robinson]. Active visualization seeks to present images that match some of these eye motions. This is over and on top of capabilities that are currently being exploited, such as head and body navigation. One advantage of active visualization is that we can now display foveated images, which have considerably lower data bandwidth than uniform resolution images (see logmaps below).
