i thought about this some more on the drive home yesterday, and i came up with some more applications:
1) Dance Club Mega Party VR - its a party, in your living room! choose your DJ and music style, add more clubbers around you and dance the night away.
this will be huge in the 12-16 boys/girls demographic and all ages in Japan ,Korea, and China. Plus, if a friend brings his/her headset you could dance together!
2) Live Pop-Rock Mega Show VR - get a front row ticket to the performance of a lifetime by your favorite artists and even get on stage with them! simulated crowd optional.
3) University/College (Mega?) Education VR - sit down, plug in, take a class, learn some sh*t from the best professors around the world. later you could take tests and maybe earn a degree.
4) See-The-World Mega Tourist VR - skip the long lines and walk around the world's greatest tourist attractions, museums, palaces, gardens and historic landmarks.
don't steal my ideas! i will start up a company to create these things. really, it has a huge market potential.
