How did James J. Gibson's concept of affordance influence the field of Human-Computer Interaction?
Gibson's concept introduced the idea that objects and environments offer potential actions based on their physical properties.
In what way did Don Norman adapt Gibson's idea of affordances for HCI?
In what way did Don Norman adapt Gibson's idea of affordances for HCI?
Norman focused on perceived affordances, emphasizing how design influences users' interpretations of an object's function.

Study Notes
Affordances and Human-Computer Interaction (HCI)
- Affordances describe potential actions offered by an environment or object to an individual.
- James J. Gibson introduced the concept in ecological psychology.
- Affordances are crucial in Human-Computer Interaction (HCI).
- Affordances are directly related to perception. They show what the environment encourages us to do.
- Examples: A chair affords sitting, a staircase affords climbing.
- Don Norman adapted Gibson's idea for HCI.
- Norman focused on how objects and interfaces are designed based on user interpretation.
- Perceived affordances are how users interpret what an object or interface allows them to do.
- Example: a button on a screen suggests clicking.
- Perceived affordances are crucial for intuitive design in HCI.
- Affordances bridge the gap between design and usability.
Types of Affordances
-
Real Affordances: Physical properties allowing specific actions.
- Example: A door handle enables pulling or pushing.
- In HCI, a mouse allows dragging, pointing, or clicking.
-
Perceived Affordances: Visually or symbolically designed to indicate use.
- Perceived affordances may not always match real affordances.
- Example: a flat button in an app suggests tapping.
- They are essential for intuitive design in HCI.
Conclusion
- Affordances connect design to usability.
- Real vs. perceived affordances were emphasized by different individuals.
- Recognizing affordances results in intuitive and user-friendly designs.
