Abstract

This study explores the impact of font selection, hyperlink presence, memory retention, and visual acuity on digital reading experiences for older adults. Initially designed to evaluate the effects of font types and hyperlinks on reading outcomes, the study adapted its approach after participants indicated a strong dislike for hyperlinks and largely avoided using them. Using a multiple linear regression analysis, this research examines how font choices, memory, and visual acuity influence reading speed, comprehension, engagement, pleasure, and fatigue. Variance Inflation Factor (VIF) analysis was employed to address multicollinearity. Results indicate that familiar fonts, strong memory retention, and good visual acuity enhance engagement, comprehension, and reading pleasure, while older age and specific article types contribute to increased fatigue. These insights provide valuable guidance for optimizing digital content design to improve readability, accessibility, and user experience for aging populations.
