The effect of icon color gradient features on users' visual search efficiency

Area of Science:

• Human-Computer Interaction
• Visual Perception
• Graphic Design

Background:

• User interface design relies on effective icons for efficient information processing.
• Understanding how visual elements like color gradients and areas impact user performance is crucial for optimizing icon usability.

Purpose of the Study:

• To investigate the impact of varying color gradient slopes and color areas within icons on user visual search efficiency.
• To determine which icon design characteristics enhance search accuracy and reduce search time.

Main Methods:

• A visual search task experiment was conducted with 35 participants.
• Participants evaluated icons with different color gradient slopes and color areas.
• Key metrics included search accuracy and search time.

Main Results:

• Icon color gradient slope significantly influenced visual search efficiency.
• Higher color gradient slopes correlated with increased search accuracy and shorter search times.
• The color area of an icon (graphic vs. background) affected search accuracy, with graphic areas performing better.
• The effect of color gradient slope on search time was more pronounced when the gradient was within the graphic area.

Conclusions:

• Icons featuring steeper color gradient slopes and a colored graphic area demonstrate superior performance in visual search tasks.
• These findings provide actionable guidance for designers aiming to improve icon effectiveness and user experience.
