Holograms to replace video conferencing?

The audience was all of a buzz when the mobile three-dimensional image of Telstra's chief technology officer, Hugh Bradlow, was broadcast from Melbourne to Adelaide to give a live business presentation.

Bradlow used a high-definition video camera to film himself. This was sent across the network to a smart optical projection system at the press conference that created the hologram.

He could see who he was talking to because he was watching a big, flat panel screen, allowing the real time interaction.

Bradlow claimed it had the look and feel of being in the same room. The technology was possible because of Telstra's Next Gen IP system.

Telstra claims it will be commercially available within four or five years time, the delay mostly due to the technology being currently so expensive.
