1	Methods to support innovation and evaluation of mobile services for people Kristina Höök SICS (Swedish Institute of Computer Science) Professor Human-Machine Interaction at DSV Stockholm University/KTH
2	Challenges 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
3	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
4	In the real world: GeoNotes
5	78 users, 1 month, 283 notes, 84 placelabels, 28 access points
6	Placelabels
7	Hocman: ad-hoc transfer during quick encounters
8	Kista
9	Back-seat gaming

11	eMoto
12	Total recall
13	Ubiquitous graphics
14	Lomograph-inspired context-aware camera Hue, saturation & value (e.g. affected by temperature, pollution and sound) The effects of the sensor input can be seen in real-time
15	OpenTrek: OS for shared games

17	Think outside the box Make the world the screen Connect place and information Connect devices to create big screen Extend screen by using devices that interact with position Use other modalities: sound, gestures, music
18	Andrew Herbert, Microsoft Research Bildskärm på skrivbord är den sjätte föråldrade idén. 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	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

21	Methods
22	Persona (Cooper 1999)
23	Ethnography (quick and dirty)
24	Cultural probe (Gaver et al. 1999)
25	Bodystorming (Oulasvirta et al 2003)
26	Tiny fingers (Rettig, 1994)
27	Wizard of Oz (Dahlbäck 1993)
28	Experience clip (self evaluation (Isomursu, 2004)
29	Cultural probe as evaluation
30	Methods
31	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
32	Summary think outside the box design specifically for some well-defined user group involve users at all stages evaluate properly in “the wild” methods do not have to be boring! not expensive!
