From a projection point of view I think this is really seamless, and can imagine the applications are endless. But for the positives I feel it is perfectly set up to broadcast a speech or performance only and one-way-dialogue whereas doesn’t allow for any engagement or interaction.
The future of telepresence is illustrated by a business with a Star Trek themed service called Beam There. This is far richer than a pure video conference and quite realistic too. Hopefully it helps cut back on the 100000 flights a day that we currently have.
