Introduction to usability

Usability is the ease of use and learnability of a human-made object.

The object of use can be a software application, website, book, tool, machine, process, or anything

a human interacts with.

about the “Usability motivations” that allows the user to have a good and easy-

We talk

understandable interface when he/she uses services or software (banking system, corporate

databases and intranets, transportation tickets, airline check-in, mobile phones and other gadgets).

The “Usability goals” are : Effectiveness, efficiency & satisfaction. They are measured by: time to

learn, speed of performance, rate of errors by users, retention over time and subjective

satisfaction.

When a software is designed, you have to think that there are eight mainly golden rules to

considerate in the interface : strive for consistency, cater to universal usability, offer informative

feedback, prevent errors, design dialogs to yield closure, permit easy reversal of actions, support

internal locus of control, reduce short-term memory load.

Usability and Web Design

Usability is the practice of designing and architecting websites to focus on the user's experience.

The International Standards Organization (ISO) official definition, usability is "The effectiveness,

efficiency, and satisfaction with which users can achieve tasks in a particular environment of a

product. High usability means a system is easy to learn and remember; efficient, visually pleasing

and fun to use; and quick to recover from errors."

To understand the concepts of Usability and Web Design we have done it in practical.

We spent the majority of time to do the lab part that consisted in choosing one of the site showed

in the teacher’s list and using it to test the usability.

Me and my group chose the “University of Helsinki” site. It is a good site where it is easy to find

information an user needs. It is not required to do lots of clicks to get the information you are

looking for and it is well-built site with a good user interface.

“The Web Usability Guidelines” which you can check here :

Psychology of interface design

Usability is a standard, definite in ISO 9241.

It is the effectiveness, efficiency, and satisfaction with which users can achieve tasks in a particular
