Researchers at the University of Washington have developed the ‘Vocal Joystick’ software, which allows disabled people to use computers in a better way. The software allows the computer to be driven by sound, in pace of the conventional functioning mouse. The difference between the Vocal Joystick and other technologies is that it does not use standard voice recognition technology and instead detects basic sounds at about 100 times a second and generates a fluid and adaptive cursor movement. It is said that the system allows users to exploit large sets of sounds for continuous and discrete movement. The Vocal Joystick does the job with the help of a microphone, computer with a standard sound card and a user who can vocalize.
Pricing and Availability: It has just been developed by the researchers at the University of Washington and may take time to be made available commercially. The price is not known either.
Watch This: The mouse can be controlled with basic sounds such as ‘ahh’, ‘ooo’, ‘ohh’ and others for different directions. This assistive-technology based system could help the disabled to lead a more productive life.
Word around the Web:
“Say “ahh” and the cursor zips toward the northeast corner of the computer screen. “Ooo” sends it shooting straight south. Want it to head southeast? Say “ohh.” To make the cursor do a circle or figure 8, let vowel sounds bleed into one another, like eee into ahh into aww and so on.”
