This document discusses human-computer interaction (HCI) research in user-centered design (UCD). It begins with definitions of key terms like UX, HCI, and UCD. It emphasizes the importance of UCD in improving software success rates and reducing costs from poor requirements gathering. The document then provides examples of HCI research areas like the technology acceptance model for predicting product usage and recent approaches using neuroscience. It concludes by encouraging the adoption of UCD principles and referring to knowledgeable resources in the HCI field.

7. Definitions
? ^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. ̄

8. Definitions (cont¨d)
? Discipline under which researchers study ^interactive
computing systems for human use ̄
? Not primarily Human nor Computer

11. Why Should We Care?
? Software success rate:
C 24% Failed
C 44% Challenged
? More than 50% of
failure is due to
C Poor requirements
gathering
C Not only functional!

12. 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

13. Why is UCD Important?
? It all starts with: Frustration
? Perception is the key!

15. Why is UCD Important?
? It all starts with: Frustration
? Perception is the key!
C The past: our experience
C The present: the current context
C The future: our goals

18. Perspective Matters
? Design guidelines explain goals
not actions
? They are like laws not recipes:
C lawyers should interpret
? We need theory-based
approaches:
C ^we have a hodgepodge collection
of do-it-yourself categories and
19
various collections of rules-of-
thumb ̄ (Gray and Salzman, 1998)

? This is one of the main perspectives!
? Let¨s imagine a case: predicting if people will use a
product

Usefulness
Actual
Use
Perceived
Ease of Use
