Mevael Corporation, in Japan, has developed a one thumb keyboard
for text entry and mouse manipulation. The invention is based on the premise that kids in Japan are faster at text entry on their mobiles than on a QWERTY keyboard. I think it would be really cool to couple it with a wearable that uses a near eye display like something from Xybernaut
. I know I'd have an easier time entering text on a phone key pad than trying to learn the chording technique other wearables require.
