Description: Patients with Age-related Macular Degeneration (AMD) use magnification to improve recognition ability. As magnification increases, the amount of information presented in the visual scene is reduced, impairing the viewer's ability to perform non-sequential reading tasks. To improve AMD patients' access to electronic text, a visual aid that multiplexes global screen layout with a magnified image was developed. In a study comparing the non-sequential reading performance of a Multiplexed Magnifier (MM) to a Permanent Magnifier (PM), AMD patients performed 13% faster with MM. Improved task performance was the result of faster reading, facilitated by increasing the size of the magnifier. The increases in magnifier size improved reading performance by reducing the need for coordinated hand-eye movements. The results demonstrated that AMD patients performed non-sequential reading more effectively (in less time and with fewer errors) when aided by a Multiplexed Magnifier.
