Together with colleagues from Nokia, VTT, and CMU we organized a workshop on Context-Aware Mobile Media and Mobile Social Networks at MobileHCI 2009.
The topic came up in discussions some time last year. It is very clear that social network have moved towards mobile scenarios and that utilizing context and contextual media adds a new dimension. The workshop program is very diverse and ranges studying usage practices to novel technological solutions for contextual media and application.
One topic that is interesting to further look at is to use (digital) social networks for health care. Taking an analogy in history it is evident that the direct social group you were in took were the set of people that helped you in case of illness or accident. Looking at conditions and illnesses that cause a loss of mobility or memory it could be interesting to find applications on top of digital social networks to provide help. Seems this could be a project topic.
In one discussion we explored what would happen if we would change our default communication behavior from closed/secret (e.g. Email and SMS) to public (e.g. bulletin boards). I took the example of organizing this workshop: our communication has been largely on email and has not been public. If it would had been open (e.g. public forum) we probably would have organized the workshop in the same way but at the same time provided an example how one can organize a workshop and by this perhaps provided useful information for future workshop chairs. In this case there are little privacy concerns but images all communication is public? We would learn a lot about how the world works…
About 10 years ago we published at paper there is more to context than location . However, looking at our workshop it seems: location is still the dominant context people think of. Many of the presentations and discussions included the term context, but the examples focused on location. Perhaps we do need location only? Or perhaps we should look more closely to find the benefit of other contexts?
