So, HMD's for gaming have been a dream since the beginning of gaming. There have been a bunch of them over the years. Most of them fail miserably. I've yet to hear of one that didn't suck. The military uses them for a bunch of different stuff.
But with the rise of Google Glass, I believe more attention will be brought to HMD's for gaming. There is already a sony device out that cost something like 800 Euroes. But it's only compatible with sony blu-rays (I think?) and PS3's.
I would think that there would be greater interest in HMD's for gaming due to popular manga/anime such as .hack (whose MMO, The World, utilizes HMD's) that it would be more popular.
Anyways, this thread is to discuss HMD's for gaming. Share your thoughts, opinions, interesting technologies, etc...
