Bridging Artefacts

I began my participation in CHI2010 in Atlanta, USA, participating in the workshop “Bridging the Gap: From Contextual-Analysis to Design“.  At the session I presented our position paper on contextual analysis for infrastructure awareness, and to my satisfaction it was very well received.

Awareness in Social Networks

Back in 97, the CHI community was putting some effort in the creation of remote awareness platforms. These platforms allow friends and relatives to experience awareness of the other’s activities.
