Here is something to make Visor wearable (Score 2)

Check this out: http://www.halfkeyboard.com/product/index.html Featured at the most recent ComDex - you wear the visor/palm on your left wrist (software rotates the screen to lanscape) and a halfkey board on your right, with a cable (presumably) going up your arm, across your shoulders and back down. I won't explain how the half-keyboard works - check out the site. There is an app to download that remaps your keyboard so you can try it out.
