activities. These related to providing fast access to information (N=33) when mo-
bile, or at home, by alleviating boredom in idle periods (N=18) through activities
such as browsing the web, browsing photos or playing games, by enabling capturing
momentary information (N=11) when mobile, either probed by external stimuli or
during introspection, and by avoiding negative social situations (N=8), e.g. when
identifying typed phone numbers from contact list before establishing a call, en-
abling easy access to destination time when calling abroad, or allowing a fast mute
of all sounds when being in a meeting:
[Long-term usability, day 3] “turning the iPhone sideways not only turns the
page but also magnifies it, so text is easily readable. Truly well done! I don't
see this kind of attention to details too often”, [fast access to information,
day 3] “it's so easy to just pick up the phone to check the web rather than
having to switch the computer on - I am becoming a great fan of it. It's simply
saving time”, [alleviating boredom in idle periods, day 7] “I like playing - I
find it a nice activity when waiting, traveling and at any point when I can't
really do anything else”, [capturing momentary information, day 12] “Now
I tend to go joking when I want to think of my work as I can easily write down
whatever comes to my head”, [avoiding negative social situations, day 22]
“It was so nice that iPhone recognized a phone number from my contacts list
and showed it to me before I started calling. Thanks to that I didn't leave yet
another voice message that would be staying there for another week or two.”
