New technology using rapid prototyping and development with 3D printing is giving visually impaired the ability to see objects and judge distance.
The design is not to give sight back, rather to take advantage of what sight the user has. It does this by sensing both depth and movement. Cameras and sensors pick up the objects in the room, they then display the objects in the room on a transparent OLED screen in a more basic colour and apply brightness to the objects that are closer and darken the objects that are further away, thus giving depth perception to the user that before would have been a blur. this greatly increases the users spacial awareness allowing them to navigate places like busy high streets with greater ease and awareness.
