Definitions

UX

• “UX is the totality of the effect or effects felt by a user

as a result of interaction with … a system, device, or

product, including the influence of usability,

usefulness, and emotional impact during interaction,

and savoring the memory after interaction.”

The UX Book

Definitions (cont’d)

• Discipline under which researchers study “interactive computing systems for human use”

• Not primarily Human nor Computer– It is the study of bridge between them

• Contributing fields: Computer Science, Psychology, Design, Information Systems, …

• There are different paradigms– Design Science, Behavioural Research, …

Definitions (cont’d)

• A Philosophy or a Methodology

• Focus on designing for and involving end users– User Advocacy

• Usability is NOT UCD– It could be the Goal

UCD Cycle

From the UX Book:

Create Interaction Design Concepts

Understand User Work and Needs

Verify and Refine Interaction Design

Realize Design Alternatives

Design

PrototypeAnalyze

Evaluate

Why Should We Care?

• Software success rate:– 24% Failed

– 44% Challenged

• More than 50% of failure is due to – Poor requirements

gathering

– Not only functional!

Why Should We Care? (cont’d)

• $300M button: http://goo.gl/8pUb

• The average business metrics improvement after a usability redesign is 83%

• 81% of customers willing to pay more for a better UX

Why is UCD Important?

• It all starts with: Frustration

• Perception is the key!

Let’s play a game:

Read What You See!(The game is from: http://goo.gl/o4AVA)

Why is UCD Important?

• It all starts with: Frustration

• Perception is the key!– The past: our experience

– The present: the current context

– The future: our goals

Perspective Matters

• Design guidelines explain goals

not actions

• They are like laws not recipes:

– lawyers should interpret

• We need theory-based

approaches:

– “we have a hodgepodge collection

of do-it-yourself categories and

various collections of rules-of-

thumb” (Gray and Salzman, 1998)

How do We Work?

• This is one of the main perspectives!

• Let’s imagine a case: predicting if people will use a product

Perceived Usefulness

Perceived Ease of Use

Actual Use

Conclusion

• Adopt UCD– If you can, pay attention to research

– “Scaling Your UX Strategy” by HBR http://goo.gl/ZtPDs

• HCI provides the toolbox– Refer to knowledgeable people

• Conferences and Journals:– CHI conference, SIGCHI, IxDA and

UPA groups, CACM journal

• Books: e.g.
