Having a device that automatically translates other languages on the fly has been a sci-fi dream for years now, but we seem to be edging ever closer to having the technology on hand to make it a reality.
NEC's new Tele Scouter is a retinal-display gadget that translates what people say to you, then displays the translations as text on your glasses.
Unfortunately, it looks pretty bulky, requiring a computer to be hooked up to the glasses to do the heavy lifting.
And even then, the translations aren't really good enough to make wearing this thing in a foreign country practical. But someday, my friends. Someday.
