Frankly, no, I don't. The immersion is more than canceled out by the additional hassle, not to mention that many people (including myself) that this sort of 3D either doesn't work for or causes intense motion sickness.
So parent's comment was "it will be great once the tech improves" and your response is "no it won't because the tech currently sucks"? I think you're missing his point.
No, not at all. I am saying the CONCEPT sucks. It's not really a technology issue, since to overcome it we would need to be at like literally jack-in-to-the-brain, bypassing the optic nerve levels of tech. At which point we will probably have something better to do than play Half Life 3D.
If your only experience is with the developer kit then you're not really equipped to make a judgement on it. Motion sickness is caused by a combination of the demo in question and the fact that the screen is pretty low quality.
Also, I'm not sure how this sort of 3D can't work for someone unless you're either blind in one eye or have some sort of issue with stereoscopic vision in general. Sounds like a configuration issue.
Well, I simply disagree. Once the technology improves, I really think it's going to become the first ever instance of true virtual reality. I think once they do a very seamless overlay that encompasses your entire vision, motion sickness may not be a problem anymore for most people.
