Viewing/playback techniques Passive Active Autostereoscopic 13/18
Passive technique Left and right images interlaced Based on polarisation Used in USA – Requires an expensive silver screen 14/18
Active technique Right and left image take turns Shutter-glasses Double frame rate Glasses synced with infrared Used in europe 15/18
Autostereoscopic technique Placing the viewer is challenging (sideways/depth) Poor resolution Cannot respond to motion parallax. 16/18
