Summary
This study shows eye movements predict perceived product attributes during design validation. Experienced users focus longer on multiple components for product impressions.
Area of Science:
- Human-Computer Interaction
- Cognitive Psychology
- Design Research
Background:
- Eye movements are key indicators of human information processing.
- Understanding visual attention to product attributes is crucial for design concept validation.
- Previous research has not clearly defined how eye movements differ across specific product attributes.
Purpose of the Study:
- To provide guidance for using eye tracking in design concept validation.
- To investigate how eye movements relate to perceived product attributes.
- To explore the differences in eye movements based on user experience.
Main Methods:
- Two case studies were conducted involving 105 participants evaluating product images.
- Eye movements were analyzed during product evaluations.
- Product attributes were investigated based on cognitive-affective emotions, apparent functionality, and affective quality.
Main Results:
- Perceived product attributes in evaluation tasks can be predicted from eye movement data.
- Experienced users exhibited longer mean fixation durations compared to new users.
- Experienced users tended to form product impressions by integrating information from multiple components.
Conclusions:
- Eye tracking is a viable method for design concept validation by predicting perceived attributes.
- User experience influences visual attention strategies and impression formation processes.
- Further research can leverage eye tracking to refine product design and user understanding.
