The Head Mounted Display (HMD) from Sony is a personal entertainment system that allows you to game and view movies in 3D High Definition along with virtual 5.1 surround sound.  Sony uses OLED screens that can be adjusted to your eyes to create an optimized High Definition and 3D picture.  OLED screens are used because they are flicker free and easier to watch over long periods of time, without motion blur or lag. The Head Mounted Display is equipped with a HDMI cable that you can simply plug right into your PS3 or Blu-Ray Player.
