Abstract

Disclosed is a magnification device with multiple orientations. This allows a blind or low vision user to select the best orientation for the task being performed. The device includes both opened and closed orientations. It is further configurable into document reading, near object inspection, far object inspection, and self inspection modes. The camera of the device can be manipulated by the user depending upon which of these orientations is selected. Furthermore, the camera automatically adjusts itself into one of two pre-set configurations whenever the device is opened or closed.

a rotatory damper (94) associated with the brake release mechanism (74), the rotatory damper (94) slowing the temporary release of the brake (74) such that the barrel (48) has sufficient time to achieve the forward most position.

2. A video magnification device (20) comprising:
