8. “Designing the new interface was a daunting task.
First, we made an advanced prototype by cutting
out a roughly-tablet-sized piece of cardboard,
writing ‘iPad’ on it, and carrying it around for a few
days. We would bring it to meetings, hold it in
different ways, and try to imagine what Evernote
would feel like on this form factor. We looked
pretty stupid and people made fun of us
mercilessly. We printed out Photoshopped UI
screens and taped them to the ‘iPad’ to get an idea
of font sizes and finger placement. We learned a
lot.”
11. “We […] threw away all of our previous designs.
After some trial and error, we got something that we
fell in love with.”

13. “Paper prototyping is a variation of usability testing
where representative users perform realistic tasks
by interacting with a paper version of the interface
that is manipulated by a person ‘playing computer’,
who doesn’t explain how the interface is intended
to work.”
18. Wichtig
‣ Test immer vorbereiten!
‣ genaue Definition des zu testenden
Interface-Konzepts
‣ alle Materialien fertigstellen, die benötigt
werden, um den Test durchzuführen
19.
20. Vorteile
‣ frühes Feedback
‣ schnelle Änderungen
‣ verbessert Kommunikation mit allen
Projektbeiligten, insb. mit dem Kunden
‣ keine technischen Vorkenntnisse nötig
‣ lädt zum Herumspielen ein
21. Größter Vorteil
“Most software is like [an iceberg] -- there's a pretty
user interface that takes about 10% of the work, and
then 90% of the programming work is under the
covers.”
Joel Spolsky

25. Beteiligung
Das ganze Team:
‣ Designer
‣ Entwickler
‣ Techniker
‣ Nicht-Techniker
Techniker und Nicht-Techniker sollten sich die
Waage halten.
Technik hat das letzte Wort.
33. Usability Test
‣ Ziele und Zielgruppe definieren
‣ Aufgaben für die Zielgruppe erstellen
‣ Papierprototyp erstellen
‣ Selbst durchspielen/testen
‣ Testen und nach jedem Test verbessern
‣ Erkenntnisse festhalten und
kommunizieren
