NI India Graphical System Design Achievement Awards Humanitarian Award Winner
Every day we rely on our eyes to observe and analyze objects around us, and guide us to a pathway that will prevent collision. Sometimes our eyes falter and we need assistance in figuring out where to go, so researchers at IIT Kharagpur created a vision-based electronic navigation system that can help.
More commonly known as an electronic travel aid (ETA), the system helps the visually impaired navigate the environment easily and more efficiently. Using an NI 1762 Smart Camera and NI LabVIEW software to identify and classify living, nonliving, moving, and other material objects within a 5 m range, the ETA calculates distance from object to wearer. The system prepares alternate navigation paths around the objects and communicates the path to the user through speech messages. These messages can be programmed in different languages, which is a capability that many vision-based electronic navigation systems lack.
The entire system is based on LabVIEW software and the NI 1762 Smart Camera using the NI Vision Builder for Automated Inspection. This lets the system be compact and lightweight while highly effective. The system successfully detects human presence, chairs, tables, beds, television sets, refrigerators, doors, cupboards, and telephones. When the human face is not in the camera’s field of view, the system can still understand a human’s presence. Now you really don’t have to watch where you’re going anymore!
