Researchers Develop Holographic Videoconferencing System


Researchers developed the world’s first truly holographic videoconferencing system, on April 30, 2018.

A team of researcher from Queen’s University announced the development of TeleHuman 2, which is the world’s first holographic videoconferencing system. This system allows people in different locations to virtually see one another in life-size 3D view, giving them a feeling as if they were in the same room.

“People often think of holograms as the posthumous Tupac Shakur performance at Coachella 2012. Tupac’s image, however, was not a hologram but a Pepper Ghost: A two-dimensional video projected on a flat piece of glass. With TeleHuman 2, we’re bringing actual holograms to life.” said Roel Vertegaal, co-author of the study.

The team used a ring of intelligent projectors mounted above and around a retro-reflective, human-sized cylindrical pod, this allowed for light fields to be walked around and viewed from all sides simultaneously by multiple users. The team was able to teleported live 3D images of humans from one room to another by capturing the remote 3D image with an array of depth cameras. The display projects a light field with many images, due to which users are not required to wear a headset or 3D glasses to experience each other in augmented reality.

“Face-to-face interaction transfers an immense amount of non-verbal information. This information is lost in online tools, promoting poor online behaviors. Users miss the proxemics, gestures, facial expressions, and eye contact that bring nuance, emotional connotation and ultimately empathy to a conversation. TeleHuman 2 injects these missing elements into long-distance conversations with a realism that cannot be achieved with a Skype or Facetime video chat.” Said Dr. Vertegaal, lead author of the study.
