Eelke Folmer and Vinitha Khambadkar think blind people could do without their white canes and instead navigate with a camera around their necks that gives spoken guidance in response to hand gestures.
Folmer and Khambadkar, researchers at the University of Nevada, presented the technology last week at the ACM Symposium on User Interface Software and Technology. Known as the Gestural Interface for Remote Spatial Perception, which they abbreviate as GIST, the system utilizes a Microsoft Kinect sensor to analyze and identify objects in its field of view. “GIST lets you extract information from your environment,” Folmer says.
