Influence of Sleep Monitoring Terminal Displays-Related Factors on User Visual Perception via Eye-Tracking and Tasks

Area of Science:

• Human-Computer Interaction
• Visual Perception
• Sleep Science

Background:

• Sleep monitoring terminal displays (SMTD) offer sleep profile data but present interface challenges.
• Limited research exists on SMTD interface design and its impact on user visual perception.
• Understanding user interaction with SMTD is crucial for improving sleep cabin environments.

Purpose of the Study:

• To evaluate how SMTD interface factors, including stimulus areas of interest (AOIs), user experiences, and tasks, influence user visual perception.
• To investigate the effects of SMTD interfaces on visual perception within authentic, eye-tracking experimental contexts.
• To provide insights for optimizing SMTD digital interface development.

Main Methods:

• Utilized eye-tracking experiments in realistic settings to analyze SMTD interface interactions.
• Collected data from 40 valid samples, measuring pupil sizes (PSs), task performance, satisfaction, and usability.
• Employed statistical analysis to compare user visual perceptions under varying tasks and interface conditions.

Main Results:

• User experiences and stimulus AOIs significantly affected pupil sizes (PSs), indicating altered visual perception.
• Task completion time ratio and tracking ratio differed between tasks, with varying physical and mental demands.
• Tasks themselves did not show a significant effect on PSs, suggesting other factors were more influential.

Conclusions:

• User experience and stimulus AOIs are key factors in SMTD visual perception, influencing pupil size.
• Optimized SMTD interfaces, validated by subjective and objective metrics, improve user visual perception.
• This research offers valuable insights for designing effective digital interfaces in sleep monitoring systems.
