Original Kurzfassung:
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.
