MORE THAN JUST MEETS THE EYE: A little oldie but definitely a goodie: Researchers at Georgia Tech devised an app for visually impaired people to be able to type without having to look at the screen. Braille Touch, a free open-source app, maps the six finger chording process used in traditional Braille keyboards onto a touchscreen. Users use the middle three fingers of each hand to type the "chord"for each letter, number and symbol. Tests revealed that some nimble users were able to type up to 32 words per minute with 92% accuracy. Hey, the six-key input also sounds like a possible solution to the problem of typing with stubby fingers on a compact QWERTY keyboard. Still, lead researcher Mario Romero doesn't recommend that you try driving and texting with his new tool.
