US: Toyota has developed a wearable gadget that could help visually challenged people in navigating indoor spaces. Known as Project BLAID, the wearable gadget can be wrapped around the person’s shoulders. Then it scans the environment using built-in camera and communicate the information to the user in the form of vibration and speakers. For making it more efficient, Toyota is adding on facial recognition software along with mapping and identifying specific objects. In other supporting features, it can auto-detect things like stairs, elevators, exit signs and logos. The gadget has not yet completely developed. However, Toyota hopes that it will be ready for beta testing in the near future.
