Oct. 19, 2007 -- "Ah," "ee," "aw" and "oo" are not just vowel sounds, but vocalizations that can now control a computer cursor. The Vocal Joystick detects sounds at 100 times a second and then turns them into movements on the screen.
The device could help people with disabilities surf the Internet, draw, play video games, control an electronic wheelchair and even operate a robotic arm.
"If you have full vocal capabilities, it's very natural and doesn't require anything special," said Jeff Bilmes, an associate professor of electrical engineering at the University of Washington in Seattle.
The system is essentially a software program that allows users to specify any sounds they want and then associate them with movements otherwise controlled by joystick knobs or buttons.
For example, "ah" could drive the cursor up; "oo" send it down; "ee" make it go left and "aw" make it go right.
A hard "k" sound could do the same thing as clicking a mouse button and a "ch" could simulate releasing the button. Increase the volume and the cursor moves faster.
The technology calls to mind Victor Borge, the musician and comedian famous for his "Phonetic Punctuation" routine, in which he recited a story, making onomatopoetic sounds for the commas, periods, question marks, etc.
And it's no surprise.
