摘要
An input device designed to allow persons of reduced visual acuity to manipulate computer software providing magnification is disclosed. The device attaches to a personal computer via standard peripheral attachment, e.g., Universal Serial Bus. A single, large, lighted button on the superior surface of the device allows the activation and deactivation of computer software providing magnification. A bezel beneath the button may be rotated to control the level of magnification applied by the computer software providing magnification.
