C 2 – Impossible Colors • Simple model for each eye • Retinal Rivalry – Neural experience in C 2 – Pseudo C 2 ~ GIFs – Perception variation – Alternative Correction
Performance • 30 FPS (Camera API) • CPU: 7% • RAM: 232 MB • GPU: 96% • 2.4 Hours Battery
Challenges • Real time imagery – Refresh Rate – Time delay • Proper stereoscopy • Field of view – Fisheye Lens
Future Directions • Medical studies – Usability of diagnostic tools – Vision improvement • Sensory expansion – UV/IR – Sound – Magnetic fields, other data sources
