Summary
Deaf individuals viewed television captions, spending 84% of their time looking at captions. Caption speed had minimal impact on viewing habits, though individual viewing patterns varied significantly.
Area of Science:
- Audiology
- Human-Computer Interaction
- Media Accessibility
Background:
- Deaf individuals often rely on television captions for content access.
- Understanding viewing patterns is crucial for optimizing caption design and delivery.
Purpose of the Study:
- To quantify the eye-tracking gaze patterns of deaf individuals watching captioned television.
- To assess the influence of caption speed and demographic factors on caption viewing time.
Main Methods:
- Eye movements of 23 deaf participants (ages 14-61) were recorded at 30 Hz.
- Participants watched four 2.5-minute captioned television programs.
- Analysis focused on the percentage of time spent viewing captions versus the video picture.
Main Results:
- Subjects spent 84% of viewing time looking at captions, 14% at the video, and 2% off-screen.
- Caption speed (100-180 words per minute) showed minimal effect on caption viewing duration (82% to 86%).
- Significant inter-subject and intra-subject variability in caption viewing time was observed.
Conclusions:
- Deaf viewers prioritize caption content, dedicating the majority of their visual attention to it.
- Caption viewing behavior is robust across different speeds, suggesting adaptability.
- Individual differences in viewing strategies warrant further investigation for personalized media accessibility.
