The PC meeting for Percom 2009 took place at IBM in Hawthorne, NY. Percom had about 200 submissions and many good ones – so we could compile an exciting program across the whole field of pervasive computing and communication. As one of three program vice chairs I have looked in detail in about 1/3 of the submissions that were application related. It is interesting to observe that research as a whole in the field becomes more major and at the same time more incremental.
To me this puts up the big question in which domains will the new big innovations happen, what is the next trend after we have pervasive computing? There are luckily plenty of options, but at the moment it seems that there develops an interesting relationship between information, communication, mobility and energy. It seems that we can compensate mobility by information and communication and similarly we can reduce energy required by information available. One example is: if I know where things are (=information) I can reduce the effort required to find them (=mobility). Is there more to it?
Each time in the US – even in New York were public transport works quite well – one is surprise how alien it appears to many that it could be an option to take public transport on a business trip (e.g. there are no first class coaches on regional trains). Flying from Düsseldorf into Newark it was convenient to take the train to Penn Station in NY City and then an express train to White Plaines. If we would not have gone for a walk in the city we probably would have been equally fast as by car. With the again low gas prices in the US (less than 2U$ per gallon, down from 4 just a few month ago) I would expect public transport and small cars will not gain too much popularity – before the next rise in gas prices.
