I will agree that a better way of being able to tell if someone actually has a question is a must. Jumping up and down or raising a hand only does so much. The self-made question app does sometimes help but because of the varying ways “to ask a question” I think a more official solution should be approached.
During a class in AltSpace about holding events and meetings, they actually have a system that I tried to quickly mimic with the question app, where not only an icon is displayed over a user’s head (which I was able to quickly do), but a list of the users who have a question also populate in a master list (did not experiment with). This worked for both VR and desktop mode and I’m pretty sure working something out wouldn’t be too hard (minus the fact I have zero experience with the messaging server at the moment, so that isn’t helping matters).
This sort of thing has been brought up a few times during a few meetings (spotlight, sign, etc).
Not only that, but maybe zoning the entrance to minimize the sound from there to the outer area should be considered, maybe even bringing up a popup or a sign at the entrance zone saying “This is a meeting area. Be Respectful.” or something like that. The previous meeting was just a demonstration of disaster.
