What is Human-Computer Interaction?
●   Human-computer interaction is a discipline
    concerned with:
    –   Design
    –   Evaluation
    –   Implementation
●   Of interactive computing systems for
    human use and with the study of major
    phenomena surrounding them.
Why is it Important?
●   Computers aren't just computers anymore
    (mobile phone, camera, car, washing machine,
    etc.)
●   For each £1 spent to acquire new
    customer, £100 spent to acquire him back
    if she left * (Bad user-experience? Customer
    support?)


    * Mauro New Media, 2002
Not all Knowledge is in The Head
●   Knowledge is partially in:
    –   Head
    –   World
    –   Constrains
●   Maps
●   Poems rhyme
●   Reassemble Toaster

Donald Norman's Principles
●   Visibility
    –   Where's the knob?
●   Mapping*
    –   [<<] Go to the right!
●   Constrains*
    –   Can you plug a USB upside down?
    –   Drop-down menu showing available options only
●   Affordability*
    –   Jug's handle affords holding
●   Feedback
    –   AJAX Loading!?
●   Consistency
    –   Answer call button is always green
    –   Mapping leads to consistency sometimes too
Minimalism in Art
●   Started in the 1960's
●   Art => Design => Science
●   Principles of Minimalism in Art:
    –   Minimality of Means
    –   Minimality of Meaning
    –   Minimality of Structure
    –   Use of Patterns
    –   Involvement of the Recipient

Thank You
        You think slides are ugly!?
HCI is not about the beauty of the design, it's
       rather about how usable it is :P
