Quick Premise
HCI: a master progran course in the track
“Interactive Applications”
See
http://ccs-informatica.ws.dei.polimi.it/

Specializzazione”
for an overview of the track
Sinergies with other courses in the same
track
iTV (prof. Cremonesi)
Problem analysis atelier (prof. Paolini)

What is HCI?
HCI is concerned with the design,
evaluation and implementation of
interactive computing systems for human
use and with the study of major phenomena
surrounding them”
(ACM SIGCHI, 1992)
ACM = Association for Computing Machinery
SIGCHI= Special Interest Group for Human Computer
Interaction
HCI – a switch of perspective
TRADITIONAL PERSPECTIVE
OF A COMPUTER ENGINEER:
TECHNOLOGY AS A MEANS

Why Facebook is such a huge success?
Your opinion?
01
Why Facebook is such a huge success?
Your opinion?
Students ideas from class discussion
It reflects a need: socialization on a world wide scale
It reflects a need: a set of usefull functionality in the same
integrated environment
it is easy to use
right tool at the right time strong implementation

Some opinions on HCI
1.
HCI is a «light, soft» matter
2.
HCI is just about users
3.
HCI is just about building nice interfaces to
interactive products and services
4.
HCI does not offer strong business
opportunities
01
ALL WRONG!!!
01
HCI is NOT a light, soft matter
HCI is a rigorous discipline
Strong theories
sw engineering flavor
cognitive-psychological flavor
Strong methods of analysis, design, testing &
evaluation
apparently obvious to learn, quite difficult
to apply
01
HCI is NOT just about users
HCI is about UX (User eXperience), i.e., about technology
AND users AND contexts of use
User studies are an important branch of HCI
Understanding the needs for all stakeholders
Analysing their behaviour with technology
Understanding how design solution affect users’
perceptions, attitude, and judgements
BUT
HCI is also
Creating the right design
Building the right technology
01
HCI is NOT just about users
HCI searches for the best successful technology for
the «user in context»
Key attributes for an interactive technology to be
successful
Usefull - accomplish what is required
Usable – robust + do it easily and naturally
Used – make people want to use it, be
attractive, engaging, fun
01
HCI is NOT just about building nice interfaces
Interface is the surface of a product – it must be nice,
attractive, fun
BUT
HCI is also
Integrating a nice interface with the sw architecture
behind
Addressing many technological challenges
Constant search for NEW INNOVATIVE technical
solutions
As new user needs emerge, existing technology
must be adapted and new technology must be
developed
HCI does offer business
opportunities

See Facebook and Mark Elliot Zuckerberg’s story
But even if your are not Zuckerberg, here is a success
story closer to us...
Emanuele Vulcano («software artisan – engineer»)
A Politecnico alumnus (and my former thesis
student)
Among other things, developer of Mover
(>2.700.000 downloads from Apple Store)
http://infinite-labs.net/mover/
Now on the move to Coupertino (S. FranciscoCA) as «front end engineer» at APPLE
(permanent position)
«.... e’ grazie al lavoro di tesi che abbiamo realizzato (più
che altro per le implicazioni in ambito di usabilità/user
experience) che hanno deciso di assumermi...»
In summary...
01
HCI promotes analysis, design and development
approaches that enabled professionals to better
understand user needs and contexts of use (now
and in perspective)
create and evaluate ICT artefacts from a utility
and easeness of use perspective
in order to build successful products
HCI provides conceptual methods and technological
tools to achieve these goals in systematic,
resource-effective way

Exercise on the fly
Q1) Technology as a means vs. Technology as a
means to an end: Conflicting perspectives?
YES/NO
(Motivate your answer)
Q2) Write 1-3 examples of digital services where
you think HCI issues can play or has played an
important role
01
Exercise on the fly: Results from class discussion
Q1) Technology as a means vs. Technology as a means to an
end: Conflicting perspectives?
Answer 100% YES
Why?
HCI: complementary to technology, the extension of
technology towards users
Q2) Examples of digital services where you think HCI issues
can play or has played an important role
Touch devices (iPhone, iPad...)
E-commerce systems
Mail systems
