"In this case, the swarm, which is capable of tactile interaction with a user in VR, might represent the skeleton structure of the human body flying in the air. This may bring a new level of immersion of VR communication and teleconferencing."
On the one hand these sound like spurious excuses for a few engineers to play with new toys and pretend there's some practical use, but on the other hand I'd be happy to see almost anything that would liven up yet another ball-achingly dull teleconference.
