GIST System Lets Visually-Impaired Navigate by Gestures

Oct-21-13 The GIST wearable, depth-sensing camera could soon allow the visually impaired to navigate with hand gestures and extract more detailed information from their environment.

Developed using a Kinect sensor, the GIST device gathers data in response to specific hand gestures. The system can support four different types of spatial perception functions: color sensing, human presence sensing, point depth sensing and area depth sensing. For example, if the user makes a ‘V’ gesture with their index and middle finger, the device will identify the color framed by their fingers. Making a fist gesture will trigger the human-sensing function, which will identify whether a person is in the room and how far away they are, and point and area depth-sensing can be accomplished by pointing a single finger or by an open hand gesture.
