Abstract
The paper reports on a usability evaluation of a full-screen magnifier. The evaluation was conducted with seven registered blind users in half-hour comprehension-based sessions using the ‘thinking aloud protocol’. The goals of the study were to determine whether joystick control of a screen magnifier was useful. The users found joystick control intuitive and easy to use. The feature with the strongest support was automatically scrolling through the text; the most significant usability problem was over-sensitivity of the joystick in certain modes.
