The Science Behind Good

UXs and UIsBy : Abdelrahman Othman Helal & Peter Osama

FACT !95% of Websites Fail at UX despite of the

Good UI !

Quote !

“Usability really just means making sure that

something works well: that a person of

average (or even below average) ability and

experience can use the thing – whether it’s a

web site, remote control, or revolving door –

for its intended purpose without getting

hopelessly frustrated.” – Steve Krug

1-Definitions What is a UX ?

User Experience (UX) involves a person's behaviors, attitudes, and emotions about

using a particular product, system or service. User Experience includes the

practical, experiential, affective, meaningful and valuable aspects of human–

computer interaction and product ownership (Wikipedia)

What is a UI ?

The user interface, in the industrial design field of human–machine interaction, is

the space where interactions between humans and machines occur. The goal of this

interaction is effective operation and control of the machine on the user's end, and

feedback from the machine, which aids the operator in making operational

decisions (Wikipedia)

Where The UI Fits ?

Back-end infrastructure: servers, databases and programming.

Content (i.e. words and pictures).

Information architecture: how the content is organized and navigated.

User interface: where the user interacts with the above.

2- User Centered Design (UCD)

The “U” in UI: USER; the “H” in HCI: HUMAN

“Focus on the user and all else will follow.”

(Google)

Focus on: people, their motivations, goals and behaviours.

Must be aware of technological constraints but UI design is not a technological

process.

User Centered Design (UCD) .. (Cont)

Involve users at all stages of the design process.

User Requirements

Who are the users?

How many different types of user are there?

What do they want to be able to do?

How do they currently do it?

Where do they currently do it?

Where might they want to be able to do it?

How might they want to be able to do it?

USER GOALS, STRATEGIC GOALS AND

CONSTRAINTS

What are the strategic goals (“business goals”) of the product you are creating;

what were you funded to do?

Tensions between strategic goals and user goals: how will this be managed?

What constraints do you have:

Financial

Time

Technology

People

ENGAGING WITH USERS

Interviews via Skype or Email.

Online surveys (generally better for quantitative information).

Existing published information about user behaviours.
