This is a kind of intelligent obstacle avoidance navigation glasses specially designed for blind people to travel. Traditional guide sticks can only provide simple feedback on roadblocks for blind people and cannot fully meet their daily travel needs. To this end, we designed these glasses, which combine echolocation detection and bone conduction technology, which can detect the road environment and feed back information to the blind, so that the blind can free their hands to explore life.

The neat lines fit the face to minimize the discomfort of wearing. Plastic and silica gel are used as the main materials to reflect medical feeling and affinity. The sound wave transmitting and receiving place is partially made of metal, which has good sound transmission performance and increases the sense of science and technology. Using injection molding process, the cost is controllable and easy to mass produce.
