Key Findings
- 01Stairs are a significant cause of accidents, indicating a gap in understanding user interaction with their design.
- 02An affordance-based approach can bridge the gap between architectural form and user perception of safety and usability.
- 03Existing stair regulations may not fully address the complexities of user interaction and safety.
Application
Design takeaway
Shift from designing stairs based solely on codes to designing them based on how users perceive their form and potential actions, thereby enhancing safety and intuitive use.
How to apply
When designing any vertical circulation element, analyze its physical characteristics (e.g., tread depth, riser height, handrail presence and shape) and consider how these features communicate to users about safe and easy traversal.
Project actions
- 01When designing a product or environment involving movement, consider how its form communicates its intended use and safety.
- 02Use affordance theory to analyze existing designs and identify areas for improvement in user interaction and safety.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Provides a novel theoretical lens (affordance theory) for analyzing a common but problematic design element.
- +Highlights the disconnect between regulatory design and actual user experience.
Limitations
The proposed framework is theoretical and may require extensive user testing to validate its practical application and effectiveness across diverse user groups.
Reliability & validity
Reliability would be assessed by consistent user ratings across repeated trials or similar stair designs. Validity would be established by correlating perceived safety with actual observed user behaviour (e.g., hesitation, speed of descent).
Think critically
To what extent can affordance theory be generalized to other architectural elements or product designs beyond staircases?
Design Principles
"Design for perceived affordances to ensure intuitive and safe user interaction with architectural elements."
Stairs are ubiquitous in built environments, yet are a major source of injury. By applying an affordance-based approach, designers can proactively create safer and more intuitive staircases, moving beyond mere regulatory compliance to a deeper understanding of user interaction.
What This Means for Your Design
Stairs can be dangerous because designers don't always think about how people actually see and use them. By designing stairs so their features clearly signal how to use them safely (like a wide step inviting a confident step), we can prevent many accidents.
How to use in your project
- 1.Reference this paper when discussing the importance of user perception in design, particularly for safety-critical elements.
- 2.Use the concept of affordances to justify design choices aimed at improving usability and reducing user error.

Paragraph starter
This research underscores the critical link between architectural form and user safety, arguing that an affordance-based analysis is essential for understanding stair climbability. By considering how the physical characteristics of a staircase communicate potential actions and dangers to users, designers can move beyond prescriptive regulations to create inherently safer and more intuitive environments, thereby reducing the high incidence of stair-related accidents.
