Abstract
Screen magnifiers are one of the core tools to assist people with visual impairments in accessing digital content. We introduce an approach to minimize interaction requirements by magnifying at the fixation point/area which is identified using eye tracking. Screen magnifiers mostly use the cursor to define the magnification area and ask for configuring when and how to magnify. This paper presents a modular design of a gaze based magnification tool reducing interaction tasks and thereby also supporting a good overview of the content and thereby showing potential to improve usability. Modularization supports an easy integration of filtering and personalization techniques to support adjustment of gaze based magnification to unusual eye-movements as e.g. nystagmus.
