In the doctoral colloquium at Ubicomp 2008 we saw an interesting mix of topics including work on context-awareness, interaction in smart space, home infrastructures and urban environments. Overall there is again the observation that in ubicomp topics are very broad (at least in the beginning) and that it is not easy to narrow it down.
There are many more papers to read if you are interested in tactile communication and output, here are two suggestions  and .
 Chang, A. and O’Modhrain, S., Jacob, R., Gunther, E., and Ishii, H. ComTouch: design of a vibrotactile communication device. Proc. Of DIS’02, pp. 312-320.
 Malcolm Hall, Eve Hoggan, Stephen A. Brewster: T-Bars: towards tactile user interfaces for mobile touchscreens. Mobile HCI 2008: 411-414
PS: Just one remark on the term “framework” (a favorite word to use in dissertation and paper titles) – it is not a clear term and expectations are very different, hence it make sense to think twice before using it 😉
