Area of Science:

Human-Computer Interaction
Vision Science
Assistive Technology

Background:

Reading with screen magnification involves manual scrolling, complicating standard eye movement analysis.
Traditional fixation-saccade models are insufficient due to smooth pursuit-like eye movements during scrolling.

Purpose of the Study:

To propose a novel method for analyzing eye movements during screen magnification reading.
To enable the application of standard reading models by compensating for magnification and scrolling effects.

Main Methods:

A new representation is introduced that utilizes mouse movement data to reverse the effects of screen magnification and scrolling.
This compensation technique transforms gaze tracks into a format analyzable by standard fixation-saccade models.

Main Results:

The compensated gaze tracks can be described using alternating fixations and saccades, similar to normal reading.
Analysis of compensated tracks reveals insights into the dynamic properties of gaze during magnified reading for low vision individuals.

Conclusions:

The proposed compensation method effectively standardizes gaze track analysis for screen magnification reading.
This approach facilitates a deeper understanding of reading behaviors in low vision users employing assistive technologies.
