Less is Better than More: Anthropomorphic App Icons With Small versus Large Tilt Angles Were Perceived as More Vivid

Area of Science:

• Human-Computer Interaction
• User Interface Design
• Cognitive Psychology

Background:

• App icon design significantly influences user engagement and perception.
• Understanding visual elements that enhance icon appeal is crucial for user interface development.
• Anthropomorphic icons, designed to resemble human-like forms, are increasingly common in app interfaces.

Purpose of the Study:

• To investigate the effect of tilted designs of anthropomorphic app icons on users' perceived icon vividness.
• To determine optimal tilt angles for enhancing icon dynamism and overall vividness.
• To confirm that slight tilting is an effective visual strategy for improving app icon attractiveness.

Main Methods:

• Three experiments were conducted to evaluate user perceptions of app icon vividness.
• Experiment 1 tested a 45° left tilt.
• Experiment 2 examined sequential tilt angles at 30° intervals, and Experiment 3 controlled for icon completeness.

Main Results:

• A 45° left tilt significantly increased perceived icon vividness in Experiment 1.
• Small tilt angles (e.g., 30° left or right) enhanced perceptions of dynamism and vividness in Experiment 2.
• Slight tilting was confirmed as an effective strategy for improving perceived vividness, independent of icon completeness, in Experiment 3.

Conclusions:

• Slightly tilted anthropomorphic app icons enhance perceived vividness and dynamism.
• Small tilt angles are key to improving user perception and engagement with app icons.
• Tilted icon design presents a viable visual strategy for increasing user attraction to applications.
