SMobile 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

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.

SDifferent 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

SPersona (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: 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
