"Since using gestures works well for exploring touch screen interfaces, why can't we use similar gestures to explore objects in the real world?" said Shaun Kane, an assistant professor in the Department of Information Systems at the University of Maryland, who co-developed the system. "Access Lens uses a camera to track a user's gestures and provide audio feedback about objects in the user's environment."

Kane and his colleagues have created a wearable prototype in the form of a pendant camera and a mobile PC.
"Currently Access Lens works best with paper documents, but we are exploring ways to adapt it to other objects in the environment," he added. "We're also working on improving the hardware and making it more portable. In the future, we are hoping to have smaller versions of the hardware that could utilize a wearable camera."
Kane and his fellow researchers presented their work at the CHI conference in Paris earlier this week.
