We developed a piece of software for use at a pharmaceutical trade show and had nearly 1000 people use it over three days.<p>This was exactly our experience. There was certainly a 10% who were absolutely blown away and we almost had to rip the headset off them after 20 minutes. Around 80% who were quite amazed and engrossed in the whole thing and certainly a 5 to 10% who were just meh, or felt a bit queasy very early on.<p>We deliberately programmed in an early section that would separate out people likely to feel sick early on. Our thought here was to get them out early on, rather than let sickness creep up on them.<p>I think the 5 to 10% will shrink quite quickly with new hardware. We couldn&#x27;t calibrate IPD for everyone - new headsets make this much quicker and easier to do. Reduced latency, etc. is all going to help here as well.
