I might be thinking too far into the future, BUT if i manage to EVER even get close to producing this, I'll let you guys know. If its successful. Hopefully in the future it will be like Cloud Technology, All the processing is done in the cloud, You are tracked by something that I will come up with and the glasses display whatever you like. I don't know if this is happening everywhere, But in Australia someone is doing high speed free internet everywhere thing, (I heard about it on the news or something) Which could be wirelessly adapted for the headset.
If i can pull it off, (Which I seriously am going to try) i might innervate the future ^.^. As i said the hopes of it getting produced are stupidly impossible BUT I would personally love it if i could get it working, then give it to a developer to further exploit it. in-till it is accepted by the world.
Ill think of something For the time being i might just request to put depth cameras throughout a street. Get someone to program a 3D of the street world or ill just do a dodgy one then add some more awesome stuff to it.
In the FURTHER future, I expect that out body's will be redundant, and we will no longer use them to communicate with others. (This is thinking more along the lines of SAO again, But a full virtual world like Summer wars."I think that's what it was called")
