The effect of four user interface concepts on visual scan pattern similarity and information foraging in a complex...

Area of Science:

• Human-Computer Interaction
• Cognitive Psychology
• Information Science

Background:

• User interface (UI) design influences decision-making quality.
• Eye movements and scan patterns reveal information foraging strategies.
• Understanding visual search in UI is crucial for effective design.

Purpose of the Study:

• Investigate repeatable scan patterns in users.
• Determine if UI concepts affect information foraging and task performance.
• Analyze the impact of data presentation and access time on visual search.

Main Methods:

• Quantified scan pattern characteristics across four UI designs.
• Modified interfaces based on data presentation (alpha-numerical vs. color blocks) and information access.
• Used eye tracking metrics to analyze visual search during a credit card fraud detection task.
• Evaluated findings against random data and theoretical decision-making strategies.

Main Results:

• Identified short, repeating sequence fragments in scan patterns, indicating systematic and random search components.
• Alpha-numerical data in full view led to more complete data foraging.
• Color blocks in full view resulted in faster task completion times.
• UI design did not significantly impact decision accuracy.

Conclusions:

• Goal-directed search yields repeatable scan pattern fragments, not complete patterns.
• UI design influences visual search behavior and decision-making strategies.
• UI design considerations are vital for applied domains to optimize user performance.
