Thanks for that helpful explanation.
How does someone "feel" something in a virtual world? For example if I make my avatar punch yours, how do you feel something & what do you feel?
If I get a knife and stab your virtual character, you are not going to bleed and there has been no contact with you in reality?
You don't feel anything but you'll see the boxing glove come right in your face. If you were stabbed you might see blood on the floor. It doesn't hurt but it's anxiety inducing as it's all right in your face, up close.
There are videos on You Tube if you google VR boxing.
One of my kids has the Occulus kit. It's a very immersive experience but I find it overwhelming. I can do the stuff where you sit still and throw paper planes around, but as soon as I start walking about I get motion sickness lol. The games where you are moving around in the dark and things jump out at you and you have to fight them off are genuinely very scary, to me anyway.
I think the sexual assault thing is more in the virtual bars and shops that Mr Zuckerberg has planned for us. You can imagine that some people would get a vicarious thrill from standing close to a girls avatar just to upset them, or just generally being a nuisance to others. As Mudsticks says, they don't need to assault you in real life - the violation of your personal space, the scaring you, the intimidation, will be enough to get them off.
It's a opportunity for antisocial behaviour without the consequences of a smack in the face or visit from the police. Hence the 'exclusion ring' being introduced.
VR porn can't be far off.
