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.

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!

The level of control and the experience level of the people using the system

The level of control provided by a system should be related to the proficiency and experience levels of the people using the system

Since accommodating multiple methods increases the complexity of the system, the number of methods for any given task should be limited to two—one for beginners, and one for experts.

The cost-benefit principle in UX Design

The quality of every design aspect can be measured using the cost-benefit principle

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 effect of face-ism in media and advertising!

The effect of face-ism in media and advertising!

It was found that images of men in magazines, movies, and other media have significantly higher face-ism ratios than images of women.

This appears true across most cultures, and is thought to reflect gender-stereotypical beliefs regarding the characteristics of men and women.
