A system would need to satisfy what people are looking for but cause no real safety concerns. These types of limitations may be very important in the kid industry, but say someone wants to experience complete immersion. That could be a second product that is much more expensive, used in the military, and for studies. The kid model could even have parental controls which would be another major selling point.
If a company or group succeeded in making some form of true VR, the best way to have the most success would be to have multiple levels of immersion, all of which would still be immersive. There could be an education model mainly based on ar, a kid gaming experience that creates close to 0 safety concerns (and have none of the things kids would be better off not seeing like super realistic gory scenes), maybe a couple other options, and then an expensive full experience for military use or rich adults.
