Kristina Hk SU/KTH SICS Methods to support innovation and evaluation of mobile services for people Kristina Hk SICS (Swedish Institute of Computer Science) Professor Human-Machine Interaction at DSV Stockholm University/KTH Slide 2 ">realistic usage situations: laboratory testing becomes meaningless, small bursts of usage throughout the day require new methods Challenges">" title="Kristina Hk SU/KTH SICS > baby interfaces: small screen, small buttons > context of use: not in the office, noisy environments, out in the "wild" > "> Kristina Hk 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 Slide 3 Kristina Hk 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 Slide 4 Kristina Hk SU/KTH SICS In the real world: GeoNotes Per Persson, Petra Sundstrm and Fredrik Espinoza Slide 5 Kristina Hk SU/KTH SICS 78 users, 1 month, 283 notes, 84 placelabels, 28 access points Slide 6 Kristina Hk SU/KTH SICS Placelabels Slide 7 Kristina Hk SU/KTH SICS Hocman: ad-hoc transfer during quick encounters Mattias Esbjrnsson, Oskar Juhlin and Mattias stergren Slide 8 Kristina Hk SU/KTH SICS Kista Martin Svensson, Kristina Hk, Rickard Cster and sa Rudstrm Slide 9 Kristina Hk SU/KTH SICS Back-seat gaming Liselott Brunnberg, Oskar Juhlin, Mattias stergren Slide 10 Kristina Hk 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 Slide 11 Kristina Hk SU/KTH SICS eMoto Petra Sundstrm, Anna Sthl, Kristina Hk Slide 12 Kristina Hk SU/KTH SICS Total recall Lars Erik Holmquist, Johan Sanneblad and Lalya Gaye Slide 13 Kristina Hk SU/KTH SICS Ubiquitous graphics Johan Sanneblad and Lars Erik Holmquist Slide 14 Kristina Hk 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 Hkansson, Sara Ljungblad and Lars Erik Holmquist Slide 15 Kristina Hk SU/KTH SICS OpenTrek: OS for shared games Johan Sanneblad and Lars Erik Holmquist Slide 16 ">realistic usage situations: laboratory testing becomes meaningless, small bursts of usage throughout the day require new methods Challenges">" title="Kristina Hk SU/KTH SICS > baby interfaces: small screen, small buttons > context of use: not in the office, noisy environments, out in the "wild" > "> Kristina Hk 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 Slide 17 Kristina Hk 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 Slide 18 Kristina Hk SU/KTH SICS Andrew Herbert, Microsoft Research Bildskrm p skrivbord r den sjtte frldrade idn. Framtidens bildskrmar r av plast, och de r sammanbyggda med vggar och vardagsfreml. Mus och tangentbord erstts med tal, gester eller berring. Tal p SICS 20-rsjubileum om 7 frldrade data-tekniker Finns i Fo&Framsteg nsta nummer Slide 19 Kristina Hk 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 Sjlinder Slide 20 ">realistic usage situations: laboratory testing becomes meaningless, small bursts of usage throughout the day require new methods Challenges">" title="Kristina Hk SU/KTH SICS > baby interfaces: small screen, small buttons > context of use: not in the office, noisy environments, out in the "wild" > "> Kristina Hk 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 Slide 21 Kristina Hk 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 Slide 22 Kristina Hk 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.

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 Slide 31 Kristina Hk 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 Slide 32 Kristina Hk 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!
