The HMZ-T3 is a Head-mounted display which was made by Sony to rival the Oculus rift through terms of immersion. Though technically as good as the Oculus it still is some of Sony's finest HMD technology. It boasts a 1270x720 OLED (Organic Light-emitting Diode) display with a 45° FOV. It is compatible to a PC and PS3 through the usage of an HDMI Cable.
So that's about it, I guess I should move on to actual technologies next...(Thermonuclear reactors anyone? :3)
