I don't understand why anyone would be even slightly nervous of this kind of development. I remember talking to some pretty open-minded (i.e. recreational drug enthusiast) colleagues years ago about the idea of "direct input devices". I anticipated the day when music could be input direct to the auditory nerve as it were and vision direct to the optic nerve - apologies to anyone reading who happens to be a brain surgeon. The concept of having an "input" port inserted in the body is one that I hope I survive to experience! The main problem I envisage is how a "spectator" would be able to control the "mix" of real and "projected" if one was able to "watch" video projected straight into the relevant part of the brain without the eyes being involved and could not control the human eye input. The guys I was talking to seemed quite phased by the ideas I was propounding; and yet they were happy to alter their mental state with chemicals. Where's the cloakroom?

Now all we need is the virtual John Madden add-on, and he can use his light pen to point out all the potential hazards as we walk down the street.

"You can see here Al that this car has its reverse lights on but has yet to move. Keep an eye on that one. But don't overlook that kid on the rollerblades coming towards you. He might just decide to cut block you and BAM! You're not going to drinking that latte you've got your mind set on!"

Why can't the future be now!

I don't, since I hate the idea of sticking my finger in my eye, but you get the general idea.

On the other hand, give me a non-clunky solution which will stick a HUD on my specs and I'll be right in there. The Cinemizer(sic) goggles don't count, largely because they look fecking awful!

Paging Captain Cyborg, paging Captain Cyborg ...

I do not care if the turns me into a cyborge it rocks

IT'S OVER 9000!!!

Internet memes aside, this could be a very interesting prospect, I wear contacts or glasses, so it would be different to see the world with a digital HUD.

Once the functions are increased, it could probably even do tiny things, like to check for suspicious arm movements (if you're a bodyguard/secret service agent) or even stupid stuff like tally petrol prices on the road to check on later to find which one sold at the cheapest price.

Losing one at the back of your eye might hurt though, and dropping it in the street would be expensive...

I just hope it doesn't my current health level or weapon ammo remaining, then that'd be a little too scary...
