A vision magnification system includes a fixed work area, a camera, and drive mechanism capable of moving the camera in at least one direction. The vision magnification system provides a magnified image of an object for viewing by a user and is particularly useful for individuals having impaired vision. A control device includes a pointing device, to control movement of the camera in a direction provided by the user, and a tracking device, which can be coupled to a writing instrument to control movement of the camera when the user uses the writing instrument.
