Course overview• Part 1: What is user centred design?
• real humans
• models of humans
• Part 2: How to investigate users?• observation (physical traces, environmental behavior)
• interview, questionniare

Questions:
- What is going wrong?
- Why is it wrong?
- What can be done to prevent these kinds of mismatches?

Three Aspects of Mental Models
• The design model– what the designer has in
mind about the system
• the user’s model– what the user think about
the system might work
• the system image– how the system actually
works

The user-needs gap
• Designers cooperate primarily with the paying clients
• Designers often do not know the end-users
• Paying clients often do not know the end-users

Principle #1: Know Your Users
• Exercise-1
• write down your email address & homepage
• write down your study/subject
• answer the following question:– What do you expect from this lecture?

Principle #2: Involve Users Early and Continuously
• Exercise-2
• answer the following questions:– What kind of living environment / product /
service do you want to investigate?– What kind of futuristic scenario do you want to
develop?

Why are users different?• genetic differences
– gender, color of the skin, size, etc.
• family background– traditions, social status, religion, prosperity, etc.
• peer group background– age, interests, habits, attitudes, etc.
• society/nationality– culture, language, habits, attitudes, laws, etc.

Causes for individual behavior
• Internal factors– genes
– physiological aspects
– psychological aspects
– cognitive experiences
– emotional experiences
• External factors– family
– school/education
– peer group
– work environment
– living environment
– written laws
– unwritten “laws”
– taboos

Get familiar with your neighbor
• Exercise-3– talk to your neighbor 3 minutes about some
aspects/experiences of/in your life
– your neighbor has to listen carefully, and to repeat what you said as accurate as possible
– do this exercise again with changed roles

How do we perceive the world?
• Senses– eyes
– ears
– nose
– taste
– skin
– haptic
• mind & memory• “heart”
© M. Rauterberg, TU/e 13
Get familiar with feelings• Exercise-4
– talk to your neighbor 3 minutes about some emotional experiences in your life
– your neighbor has to listen carefully, and to give feedback about his/her impression of your actual feelings now here in this room while you are talking
– do this exercise again with changed roles

Models of users• the naive vis-à-vis prototyp (don’t use this for
design!)
• a model in form of an axiom system
• a known system with structure and behavior analogous to the system under consideration
• a prototypical system (the ideal user)
• an abstract description of the relevant aspects of a system (e.g., a mental model)
