Peephole Displays

Projection displays embedded in cellphones are not everything. Reason? Privacy - you don't want many people looking at your presentation. At the same time, how do you provide a 1400x1050 display on your cellphone? Answer - provide a peephole - you've seen those wearable computer displays - the eyepiece is something you attach to your spectacles. Here, you'll hold the phone up to your eye and focus about 4 feet into the distance.
