Before the user-centred design
Pull? Push?

Oh~ a push door..

Which switch is for me?

7
So intuitive!
Before the user-centred design
8
A first step to user-centred design
Design should consider users, try not to
make user feel frustrated.
Before the user-centred design
9
First mentioned by Donald Norman in hisbook (The Design of Everyday Things)
(http://www.jnd.org/books.html)
Bad Designs fill our Surroundings
that make us feel frustrated. A philosophy,
User Centre design which means the design
should be done as close to user’s need as
possible, therefore be promoted
User-centred design (UCD)
10
User-centred design is an iterative process
where you consider users all the time
ISO 13407 provides the guidelines onachieving quality in use by incorporatingUCD(http://www.usabilitynet.org/tools/13407stds.htm)
User-centred design (UCD)
11
However, ISO 13407 only offers the
guidelines, but it does not show how to do
user-centred design..
Several approaches are suggested for
UCD• Participatory design
• Contextual design
• Empathic design http://en.wikipedia.org/wiki/User-centered_design

IASDR is held biannually. It was held in Seoul last
year. Next time the venue will be in Delft(2011).

The development of a conceptual model in user research using an
empathic design technique as the basis for user-centred design
The User centred design(UCD) is a philosophy which
promotes that the design should satisfy users
demands. The main approaches are :
• Participatory Design
• Contextual Design
• Empathic Design
Problematic Domain
14
The development of a conceptual model in user research using an
empathic design technique as the basis for user-centred design
Nevertheless, some drawbacks in participatory design
(PD) and Contextual design(CD) are found :
Require high skills to manipulate.• to co-ordinate a meeting among stakeholders• to arbitrate in conflict situation among stakeholders• to familiar with the anthropology or sociology to explore user’s need.
Heavy time cost is blamed to the longer design process.
High price to hire end-users to join/longer time/thedifficult skills.
Problematic Domain
15
The development of a conceptual model in user research using an
empathic design technique as the basis for user-centred design
Problematic Domain
To conclude,the present UCD methods(PD/CD) are
complex,high price and time consuming which means the
UCD is consequently easier to be carried out in big
enterprises,but not for the budget-limited firms or design
houses. They are less willing to use it due to the
difficulties we mentioned.
UCD for smaller design companies is just desirable,but nottouchable.
16
The development of a conceptual model in user research using an
empathic design technique as the basis for user-centred design
Research Aim To develop an economic conceptual model to in
user research by the implementation of UCD, inorder to encourage more usage.
Economic --> Easier to use
Less time consume
Lower price

The illustration of the research Aim
The development of a conceptual model in user research using an
empathic design technique as the basis for user-centred design
18
The development of a conceptual model in user research using an
empathic design technique as the basis for user-centred design
1. Context of the Current design
2. The design by Empathic skill
3. Comparisons & Model building
4. Refine model
Objectives
19
The development of a conceptual model in user research using an
empathic design technique as the basis for user-centred design
Take MP3 as the design target; users:18-25 Office Ladies
Methods/Experiments

The development of a conceptual model in user research using an
empathic design technique as the basis for user-centred design
Result: task 1(context of current design work)
Distractive!
less ideas &diverse!

1.Colour series converges tofeminine/young
II Form design tend tobe“simple”,”light weight” and
“girly”
III Function: easy to more ideas and thinkmore detail than task 1
IV Style is with quite similar direction as“soft” “fashion” and ”girly”
Result: task 1I (empathic design)

Comparison:

empathic design technique as the basis for user-centred design
Discussion
Current design pattern
•The design tends to fail to approach UCD
•Less ideas are gathered
•Ideas are more diverse
24
The development of a conceptual model in user research using an
empathic design technique as the basis for user-centred design
Discussion
Design by empathic technique :
•Design ideas converge to similar directions.
•Design ideas are fruitful and more detail
The Design work is more UCD by the empathic method
than current work!
25
The development of a conceptual model in user research using an
empathic design technique as the basis for user-centred design
Discussion
The use of personas• personas are known as the communication tools between teams or in a
team. The experiments indicated that personas also help designer’sindividual work(self communication), hence it forms the basis of thetheoretical model.
• --help designers to concentrate on users when designing
• --help designers to inspire more design ideas and think more detail
Designers concern “few personas” may induce bias when designing
26

empathic design technique as the basis for user-centred design
•Personas can be mix-used in their present work behavior
•Designers need to have the options to choose more personas.

28
The development of a conceptual model in user research using an
empathic design technique as the basis for user-centred design
Limitations
•Time constrained(10-15 mins) in the experiments which is
shorter than their usual design work
•No real product is made for users to get further evaluation, but we use the comparison between designers, it still showed significant results from the use of the personas.

Conclusions
•Current works tend to fail to approach UCD and thepersona-based model may solve the problem.
•The new model doesn’t need high skill to manipulate;themodel doesn’t need real users involves all the time;themodel doesn’t need extra cost of use. As a result, theconceptual model implemented by the empathic techniqueis more economical; the probabilities of use thereforeincrease.

Future Recommendations
•A real product can be made to do further evaluation from end-users.
•Different product range test for this model can further refine the model.
•Multi-user product test can be also arrange to extend the use of the model.
•A CAD development is needed to assist designers using personas database.
