the screen display the magnification region moves too but at a different rate the result is that the magnification region moves not only with respect to the screen display but also in relation to the magnifier frame in an exemplary embodiment the movement of the magnification region relative to the magnifier frame is proportional to the movement of the magnifier frame on the screen for example if the magnifier frame is moved from its initial centered position in the x or y direction 75 of the original distance between a lateral edge of the frame and a corresponding edge of the display screen the magnification region will have correspondingly moved relative to and within the magnifier frame 75 of the original distance between a lateral edge of the magnification region and the corresponding outer lateral edge of the magnifier frame as a result of such relative proportional movement when the magnifier frame reaches a screen edge movement equal to 100 of the original distance between the magnifier frame and the outer edge of the screen display the magnification region will have correspondingly moved to a position placing its edge coincident with the edge of the magnifier frame thus enabling content at the outer edge of the.
