“Affordance” was originally a psychology term used to define the possible actions between a person or animal and the world. Our colleague Donald A. Norman applied the term to the user-experience world in his classic book The Design of Everyday Things. Basically, in design an “affordance” is whatever can be done to an object.
The impression, and not just the first one, is largely formed at the entry point, physical or attentional, to a system or environment. People do judge books by their covers and Internet sites by their first pages.

Never mistake legibility for communication. Just because something is legible doesn’t mean it communicates. More importantly, it doesn’t mean it communicates the right thing.

Loading...If the costs associated with interacting with a design outweigh the benefits, the design is poor. If the benefits outweigh the costs, the design is good.
For example: How long is too long for a person to wait for a web-page to load? The answer to this question is that it depends on the benefit of the interaction.
The initial impression of a system or environment greatly influences subsequent perceptions and attitudes, which then affects the quality of following interactions between the user and our system.
A product is bought to be used. It has to satisfy certain criteria, not only functional, but also psychological and aesthetic. Good design emphasizes the usefulness of a product whilst disregarding anything that could possibly detract from it.
A German industrial designer closely associated with functionalist school of industrial design.

Constrains, as methods of limiting the actions that can be performed on a system, simplify usability and minimize errors. For example, dimming or hiding options that are not available at a particular time effectively constrains the options that can be selected.
Proper application of constraints in this fashion makes designs easier to use and dramatically reduces the probability of error during interaction. Simply put; constrains simplify usability and minimize errors!
Society has not improved the landscape by overfilling it with construction. Neither does a designer improved a page by overfilling it with content.
