1 Kristina Höök SU/KTH SICS 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 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

4 Kristina Höök SU/KTH SICS In the real world: GeoNotes Per Persson, Petra Sundström and Fredrik Espinoza

5 Kristina Höök SU/KTH SICS 78 users, 1 month, 283 notes, 84 placelabels, 28 access points

6 Kristina Höök SU/KTH SICS Placelabels

7 Kristina Höök SU/KTH SICS Hocman: ad-hoc transfer during quick encounters Mattias Esbjörnsson, Oskar Juhlin and Mattias Östergren

8 Kristina Höök SU/KTH SICS Kista Martin Svensson, Kristina Höök, Rickard Cöster and Åsa Rudström

9 Kristina Höök SU/KTH SICS Back-seat gaming Liselott Brunnberg, Oskar Juhlin, Mattias Östergren

10 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

11 Kristina Höök SU/KTH SICS eMoto Petra Sundström, Anna Ståhl, Kristina Höök

12 Kristina Höök SU/KTH SICS Total recall Lars Erik Holmquist, Johan Sanneblad and Lalya Gaye

13 Kristina Höök SU/KTH SICS Ubiquitous graphics Johan Sanneblad and Lars Erik Holmquist

14 Kristina Höök SU/KTH SICS 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 Maria Håkansson, Sara Ljungblad and Lars Erik Holmquist

15 Kristina Höök SU/KTH SICS OpenTrek: OS for shared games Johan Sanneblad and Lars Erik Holmquist

16 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

17 Kristina Höök SU/KTH SICS 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 Kristina Höök SU/KTH SICS 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 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

20 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

21 Kristina Höök SU/KTH SICS Methods Fantastic product! Design Interpretation Design study In the Wild! Brainstorming Persona Bodystorming Early testing: staged lived experiences Wizard of Oz Cultural probes Technical probes Tiny fingers Experience clip (self-evaluation) Ethnography

22 Kristina Höök SU/KTH SICS Persona (Cooper 1999) Sandra is a confident 29 year old woman who likes to spend time with her friends and family. She works as a trainee at a city planning office in Stockholm. Sandra does not care about how things work technically, but she likes new cool technological features and she is very happy with her new mobile phone that has a camera and MMS functionality. Persona and anti-persona Petra Sundström, Anna Ståhl, Kristina Höök

23 Kristina Höök SU/KTH SICS Ethnography (quick and dirty) Åsa Rudström

24 Kristina Höök SU/KTH SICS Cultural probe (Gaver et al. 1999)

25 Kristina Höök SU/KTH SICS Bodystorming (Oulasvirta et al 2003)

26 Kristina Höök SU/KTH SICS Tiny fingers (Rettig, 1994) All in ONE DAY! Åsa Rudström, Martin Svensson, Kristina Höök, Rickard Cöster

28 Kristina Höök SU/KTH SICS Experience clip (self evaluation (Isomursu, 2004) Minna Isomursu

29 Kristina Höök SU/KTH SICS Cultural probe as evaluation Petra Sundström, Anna Ståhl, Kristina Höök To subjects To partner

30 Kristina Höök SU/KTH SICS Methods Fantastic product! Design Interpretation Design study In the Wild! Brainstorming Persona Bodystorming Early testing: staged lived experiences Wizard of Oz Cultural probes Technical probes Tiny fingers Experience clip (self-evaluation) Ethnography

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

32 Kristina Höök SU/KTH SICS > 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! Summary

33 Kristina Höök SU/KTH SICS Examples from ”Mobile Life”
