Electrical Components

Of course! Lets say you want to remember & relish a favourite event happening b4 ur eyes and the sad part is it(event) slips off within the time required for you to take off your digital camera. I would luv to have such a gizmo.

Well, for me just thinking about it... There should be less cases of Carpal tunnel syndrome... But who knows... Maybe they'll be another similar syndrome with the eyes...

Dependant upon how any 'item' is selected it could also mean better response time by the user. IE: In military applications, a 'scout/sniper' could possibly target hundreds of items within minutes; and even prioritize them!

The ability to be hands free would open up a bunch of applications where a HMD would likely be chosen over other display/input devices such as video games. Or, imagine a VW (virtual world) where a technician is working at some controls and he sees some problems developing in the system he's working on (Given that the VW he's viewing is a 'layout' of the system he's working on)... He could almost immediately take steps to prevent 'that problem' from happening or facilitate expedited service/repairs...

The key is 'hands-free.' This ability would enable the end user to do much more things in a relatively shorter time than they could with just a kb/mouse setup; or even a HMD/mouse setup.
