Behavioral compliance for dynamic versus static signs in an immersive virtual environment

Area of Science:

• Human-computer interaction
• Cognitive psychology
• Safety engineering

Background:

• Traditional signage effectiveness can be limited by attentional demands.
• Assessing behavioral compliance in realistic scenarios is crucial for safety.
• Immersive virtual environments (IVEs) offer novel research methodologies.

Purpose of the Study:

• To investigate the impact of dynamic versus static signage on behavioral compliance.
• To evaluate sign effectiveness during both a work-related task and an emergency egress simulation.
• To explore the role of sign salience in influencing safety behavior.

Main Methods:

• Utilized an immersive virtual environment (IVE) with 90 participants.
• Assessed compliance with cued and uncued safety signs during a simulated work task and emergency egress.
• Introduced a simulated explosion/fire scenario for emergency egress evaluation.

Main Results:

• Dynamic signage presentation led to the highest overall compliance rates.
• The difference in compliance between dynamic and static signs was statistically significant for uncued signs.
• Both dynamic and static uncued signs demonstrated greater effectiveness than minimal signage.

Conclusions:

• Salient signage, particularly dynamic and uncued signs, enhances behavioral compliance when attention is divided.
• IVEs provide a viable and effective platform for studying behavioral compliance in safety-critical situations.
• Sign design and context (task demands, cueing) are critical factors influencing safety compliance.
