I'm not sure if I believe we'll all eventually walk around like Jordi Laforge or if I'm brainwashed by too much sci fi and future fashion so I just believe a visor will become a standard accessory. There were a few examples at the show.
These guys are wearing gaming visors from Vuzix. It displays video but wouldn't work as a substitute for a computer monitor. There was a Vuzix visor in the Sky Mall catalog on the plane that was going for 400 bucks. From what I gathered from their booth person they have a new version out that does virtual reality in such a way that the perspective changes depending on how you move your head. Sort of like that Wii mod we saw recently but instead of being on your TV it's an inch in front on your eyeballs.
This guy is using a TDV 3-D visor. The demo included a 3-D menu, so you walk through rooms to select what you want to watch. That's cool, but I'm not sure I want to walk through rooms to make a selection when I can have them listed on a menu instead.
Speaking of visors, remember the digital camera mask? I stopped by to see if the camera makes it heavy or awkward. Nope. The only weird thing is that there are two buttons on top, one for pictures and the other for video. Depending on what you're doing, a different colored light shines at the top of the mask so you can glance up and see what mode you're in. It works, but it's an unfamiliar thing to do so it's a little awkward. Also, there are cross hairs right in front of your eyes. Barely noticeable though.
