Area of Science:

  • Human-Computer Interaction
  • Data Visualization
  • Cognitive Science

Background:

  • Eye-tracking data analysis often involves complex metrics and requires effective visualization techniques.
  • Existing methods may not fully capture the nuanced interactions between different eye-tracking metrics or group participants based on behavioral similarities.

Purpose of the Study:

  • To develop and present an algorithmic and visual grouping method for participants and eye-tracking metrics.
  • To enhance the understanding of eye-tracking data characteristics and subject behavior through novel visualization techniques.

Main Methods:

  • Utilized parallel coordinates for an overview of metrics, interactions, and similarities, aiding metric selection and combination testing.
  • Employed a similarity matrix visualization combined with algorithmic grouping (clustering) based on affine combinations of metrics.
  • Visually encoded eye-tracking data into similarity matrix cells for simplified and understandable diagrams.

Main Results:

  • Demonstrated a method for algorithmic and visual grouping of participants based on eye-tracking metrics.
  • Successfully applied the visualization technique to eye-tracking data from participants reading metro maps.
  • Identified distinct visual groups of similar behavior among participants.

Conclusions:

  • The proposed visualization method effectively groups participants and eye-tracking metrics, offering insights into behavioral patterns.
  • The approach aids in selecting and combining metrics for a deeper analysis of eye-tracking data.
  • Further research is needed to address limitations and scalability issues, particularly concerning visual and perceptual aspects.
