Design-based guidelines for the semantic perception of emergency signs

Area of Science:

• Psychology
• Human-Computer Interaction
• Signage Design

Background:

• Effective emergency signage is crucial for public safety and evacuation.
• Understanding public perception of emergency signs is vital for improving their efficacy.
• Current emergency signs may present challenges in recognition and interpretation.

Purpose of the Study:

• To investigate the semantic perception of emergency signs using the semantic differential technique.
• To analyze the psychological impact and meaning of emergency signs for the general public.
• To identify areas for improvement in emergency sign design and implementation.

Main Methods:

• Application of the semantic differential technique to assess public perception.
• Analysis of recognition accuracy and semantic meaning evaluation of emergency signs.
• Exploration of emotional factors influencing sign interpretation.

Main Results:

• While semantic evaluations of emergency signs are generally positive, recognition accuracy issues were identified.
• Emotional factors emerged, suggesting potential for enhanced user experience and safety.
• The study identified a need for clearer, single-meaning symbols in emergency sign design.

Conclusions:

• Improving emergency sign design by ensuring recognizability and single meanings can facilitate evacuation.
• Specific design guidelines include prioritizing safety movement, clarity, and overall safety.
• Government-led educational campaigns can further enhance public understanding and reduce confusion.
