Notes by Thomas

Hej Jacob och Henrik,

Here are my (very brief) notes from the Interactions session of the
activity workshop at Pervasive2004.

Pinto & Jose': User-centered support to localize activities in
ubiquitous computing environments

----------------------------------------------------------------------------

- focusing on the "occasional" user, e.g. hospital visitor

- investigating the relationship between "the personal environment"
  and "the localized environment" and how they can be made more
  integrated



Pederson: Designing for physical-virtual activities
---------------------------------------------------

- referring to Kari's presentation (she also identifies metrics that
  work both in the physical and the virtual world)

- referring to Martijn's presentation which in part can be interpreted
  that the subjects in the study tend to refer to activities as
  (possibly uncounciously) being centred around changing the state of
  an object of interest. Thomas points out the risk of being biased
  towards either the physical or the virtual world when designing
  future environments for the support of human activity, since human
  activity can be seen as taking place in a physical-virtual space and
  human agents probably do not care (or would not like to care)
  whether the activity takes place in the physical or virtual world,
  as long as the support is afforded seamlessly.

Thanks for organising an interesting workshop!

Hej,

In case you intend to put up an online repository of material related
to task-based computing, here are three references from my
"physical-virtual" perspective you could consider to include.

(among other things defines the concept of "physical-virtual activity"
which could be of relevance)
