While it's yet to be seen if eyeglass-mountable displays will become as commonly used as, say, Bluetooth headsets anytime soon, Brother Industries at least looks to be making some steady progress at shrinking 'em down to a reasonable size, and it's got a few other tricks up its sleeve to boot. That latter bit comes from its use of a retina-scanning system as opposed to a simple LCD mounted in front of your eye, which effectively uses your retina as a screen to make it appear like images are actually floating in space in front of you. What's more, while the eyepiece currently needs to be wired to a rather sizable contraption in order to pump out those free-floating images, the company says it expects to be able to switch to a wireless system and shrink things down to a decidedly more wearable size by 2010.
