ABSTRACT:
Embodiments of a vision aid video magnification system for low-vision persons are shown and described. The system includes a balanced arm with a first portion that swivels on a base, a second portion connected to the enclosed camera, and an elbow between the first and second portions. The elbow includes a sliding spring fulcrum which enhances the smooth movement of the second arm portion and camera. The first arm portion includes an inner spring between arm tubes that helps eliminate the dead area that may be otherwise present in balanced arms. Other improvements include a flexible camera mount that preferably swivels relative to the arm, and a mirror attachment for personal care and other use. The vision aid video magnification system allows enhanced, smooth movement and versatility.
