Investigating visual expertise in sculpture: A methodological approach using eye tracking

Area of Science:

• Cognitive Psychology
• Art History
• Human-Computer Interaction

Background:

• Eye tracking advancements enable studying visual expertise.
• Research faces challenges integrating expertise studies with eye tracking in authentic environments.
• Key barriers include defining expertise levels and balancing internal/external validity.

Purpose of the Study:

• To address challenges in studying visual expertise in authentic settings.
• To investigate visual expertise specifically within the domain of sculpting.
• To establish an adequate research methodology for expertise studies.

Main Methods:

• Exploratory study involving 20 participants with varying expertise levels (laypersons, novices, semi-experts, experts).
• Utilized mobile eye tracking to record eye movements and gaze patterns while participants observed sculptures in a museum.
• Measured fixation count, fixation duration, dwell time in relevant areas, and revisits, analyzed scan paths with the eyenalysis approach.

Main Results:

• Identified differences in visual attention patterns across expertise levels in sculpting.
• Quantified gaze parameters such as fixation duration and dwell time in relation to expertise.
• Scan path analysis revealed distinct viewing strategies employed by experts versus novices.

Conclusions:

• Visual expertise in sculpting is characterized by specific eye movement patterns.
• Mobile eye tracking in authentic environments is a viable, though challenging, method for studying expertise.
• The study provides insights into the nature of visual expertise and empirical design limitations.
