That a user should not be kept waiting unnecessarily is an obvious and humane design principle. It is also humane not to hurry a user; the more general principle is: Users should set the pace of an interaction.

Design Principles – Constrains simplify usability and minimize errors

Use constraints to improve the clarity, usability and intuitiveness of your 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!

Prioritizing Web Usability – “Affordance” is whatever can be done to an object. –

“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.
