Mono-glass for Providing Distance Information

We propose mono-glass for providing distance information for people losing sight in one eye. We implemented a pilot system of mono-glass under careful consideration of precision, real-time processing and intuitive presentation. The loss of sight in one eye disables binocular disparity processing and makes short-range activities difficult. The proposed mono-glass is a wearable device with two cameras and one display. The two cameras capture the images on behalf of user’s eyes. Depth information is then reconstructed from the captured images and visualized with defocusing for the healthy eye.
