  • This type creates the illusion of three-

dimensional images by restricting the light that reaches each eye.

  • Less eye fatigue
  • Simple structure, Low cost
  • The display resolution is reduced by half.
  • The left and right eye images are

alternately displayed at very high speeds without dividing lines.

  • Clear resolution (Does not degrade)
  • Flickering
  • Battery replacement

  • The CTNet at the GSCT of KAIST in Korea is a research group focusing on interactive

performance over high-speed networks.

  • Ranging from unidirectional transmission of performing arts to the joint performance in

multiple locations, the group's mission is to develop performance technologies and rehearse networked performances on both technical and artistic scales.

  • This group envisages a new future of networked performances that will change the

way performance is planed, produced, published, experienced and appreciated, and we are active participants in every facet of this exciting future.
