Been reading the Behemoth series by Peter Watts. One of the things they keep mentioning in passing are "eyephones," a kind of stupid (pre-iPhone) name for the eye version of earphones. I find myself wanting something like this; it gets annoying trying to look at certain things and being afraid of the roommate walking in at any time (because the stupid apartment is built so you have to go through the bedroom to get to the bathroom, and the bathroom sink is in the bedroom).
It would be so simple to do, too: just one or two small screens set on a headset at a certain distance from the eye, which plugs into either the monitor jack or into a USB port. If I knew how to make one, I would.
I may have to move stuff in my room around again, so the laptop is faced away from the door, at least.
