While touch screen technology has become increasingly popular among smartphone users, the sleek screens have proved to be an obstruction for blind users, who rely on tangible clues to feel their way around. A pair of engineers at Google has been working diligently to resolve this issue, Charles Chen and T.V. Raman (who is himself blind).
The G1 is powered by Google’s Android software, and the engineers have been developing and testing technology to make the phone accessible for use without sight, such as for the blind and for drivers.Google engineer T.V. Raman has an impressive history of adapting technology to his needs.
Due to the fact that Mr. Raman cannot see the buttons on a touch screen, or feel them to ensure accuracy, he created a dialer that operates based on relative positions. The technology interprets any place where Raman first touches the screen as the #5 position, or the center of a regular telephone dial pad. In order to dial any other number, he simply slides his finger in the direction of its location (directly up for #2, and so on). If a mistake is made, the phone can be reset with a simple shake, as it detects motion.
The application is available in the Android Marketplace, an applications store for the G1, and more sighted users than blind are using the technology. Brought to you by Blue Interactive Agency, your Fort Lauderdale SEO web design and interactive marketing firm.
