Abstract

Screen magnifiers are widely used by people with visual impairments. This article presents a number of architectures for screen magnifiers. It discusses a wide range of issues related to screen magnifiers and their user interfaces. A usability study of a joystick-controlled screen magnifier is then presented.Finally, the authors suggest that performing a usability evaluation with the prospective users of screen magnifiers provides a better understanding of issues related to features and control.
