2. Kristina Höök SU/KTH SICS > baby interfaces: small screen, small buttons > context of use: not in the office, noisy environments, out in the "wild" > realistic usage situations: laboratory testing becomes meaningless, small bursts of usage throughout the day require new methods Challenges

3. Kristina Höök SU/KTH SICS Mobile Services? > All services should be mobile – accessible everywhere > But some services explore particular properties of the mobile setting: –Context –Specifically position –Ad-hoc connections between devices –Merging the physical and the digital –Limitations imposed by size and situation

Framtidens bildskärmar är av plast, och de är sammanbyggda med väggar och vardagsföremål. Mus och tangentbord ersätts med tal, gester eller beröring. Tal på SICS 20-årsjubileum om 7 föråldrade data-tekniker Finns i Fo&Framsteg nästa nummer

19. Kristina Höök SU/KTH SICS Different devices for different people? For example, elderly users: > Positive! > Twice as long! > Almost double n:o of clicks > Small icons difficult > Differences correlate with age, (working) memory ability, experience of mobiles & Internet (Sony Ericsson T68i, WAP-services) Marie Sjölinder

31. Kristina Höök SU/KTH SICS Costs > Persona: find a basis for the persona- character, write it up – two days? > Ethnography (quick and dirty): 2 (1?) weeks > Cultural probe: two days to put together, then users do it all > Bodystorming: one day > Wizard of Oz: two weeks > Experience clip: depends on application > Cultural probe as evaluation: for the evaluator, 3 – 4 days, for the subjects 2 – 3 weeks
