Summary

Higher display resolution significantly improves reading speed and accuracy. Low-resolution screens increase visual fatigue and eye strain, impacting performance over time.

Area of Science:

  • Human-computer interaction
  • Visual perception
  • Ergonomics

Background:

  • Display resolution is a critical factor in visual information processing.
  • Previous research has not fully elucidated the impact of varying resolutions on reading and visual fatigue.

Purpose of the Study:

  • To investigate the effects of different display resolutions on reading performance, eye movement, and visual fatigue.
  • To establish optimal display resolution thresholds for visual comfort and efficiency.

Main Methods:

  • Two experiments were conducted using Cathode Ray Tube (CRT) displays and a paper control.
  • Experiment 1 assessed proofreading speed and accuracy across resolutions (60, 120, 255 dots per inch [dpi]).
  • Experiment 2 analyzed eye movement parameters (fixation duration, number of fixations), reaction times, and visual fatigue ratings at resolutions of 62, 69, and 89 dpi.

Main Results:

  • Reading performance was superior on paper (255 dpi) compared to CRT displays.
  • Lower resolutions (e.g., 62 dpi) resulted in increased fixation durations and search reaction times.
  • Evidence suggests increased visual fatigue with lower resolutions, correlating with performance metrics.

Conclusions:

  • High-resolution displays (90 dpi and above) are recommended to enhance visual performance.
  • Utilizing higher resolutions can lead to more comfortable prolonged screen use and reduced visual fatigue.
  • Individual responses to display resolution effects on visual fatigue can vary significantly.
