May I ask, what kind of experiences did they try on the device? It seems well-accepted hypothesis that having artificial locomotion in VR can induce motion sickness (cases where the VR body moves but your own body doesn't), whereas with "sit", "stay still" or "walk around IRL" (and even "teleport around") scenarios are highly unlikely to cause it. There is a still a lot of experiences left in the latter scenario, though it does exclude driving games (in particular if you don't see the cockpit) or first-person shooting-and-moving-around games. And then the worst thing to do with newcomers is to put them down for a ride in a VR rollercoaster.
