In this segment, two speakers compare projector‑based augmented reality (AR) with see‑through glasses. Speaker A highlights that projector solutions may be attractive for users who cannot or do not want to wear glasses, especially to avoid nausea. Speaker B explains that motion‑sickness typically arises in highly immersive experiences where the visual system is heavily engaged, which is more common with see‑through glasses. The discussion notes that the severity of discomfort depends on the use case. For repetitive, prescriptive tasks such as assembly‑line work, overhead projector‑based AR is presented as easy to deploy, requiring no wearable equipment and thus sidestepping comfort issues.

The projector solution seems— would seem to me on the surface, just reacting to what you said, to be real interesting because I think there are some folks who would have trouble wearing glasses or might get nauseous from that. Am I thinking about that right?
Again, the nauseous feeling tends to happen for more immersive experiences where more of the real world is replaced by virtual objects. So the more that people's visual system is engaged like through the see-through glasses, then the less we see that discomfort that happens. But, you know, it really depends on the use cases. If you have a very standard, like it's an assembly line, it's a very prescriptive, you're doing the same thing over and over again, then like the overhead, like projection-based AR systems tend to be easy to use and deploy, and you don't have any issues with people having to wear equipment.
