Discoverability and understandability are two key concepts in design, particularly in the context of user experience (UX).
Discoverability refers to how easily a user can find or identify a particular feature or function in a product or system. It's about making sure that the user can locate what they need without excessive effort or confusion. This is often achieved through intuitive design, clear labeling, and logical organization.
Understandability, on the other hand, is about how easily a user can comprehend or make sense of a feature or function once they've found it. It's not enough for a user to be able to locate a feature; they also need to understand what it does and how to use it. This is often achieved through clear instructions, helpful tooltips, and consistent design patterns.
In summary, discoverability is about finding, while understandability is about comprehending. Both are crucial for a positive user experience.
Question was asked on:
The relationship between an object's properties and the capabilities of the agent that interacts with it—ergo, a chair affords support, so in turn, it affords the ability to sit on it. An affordance only exists if the agent can interact appropriately; for example, if a child is not strong enough to lift a stool, the stool does not afford lifting. Affordance is relative. To be effective, affordances and anti-affordances have to be discoverable.
