It’s like Star Trek or Star Wars where the projected image shows up in the air.
An Austrian firm is developing a giant video-conferencing system that will be deployed in public spaces in London and Vienna next year, allowing people in the two cities to meet and talk eye-to-eye.

Standing in front of the 10-foot-high, cylindrical TV screen is like looking directly into the heart of a foreign city, its inventors say.

Broadcasting 24 hours a day, the system will feature life-size images, directional speakers and microphones to keep private conversations private. Its backers hope to deploy the screens in cities around the globe.
