Re: glossary

My comments:

I find Oviatt's definition quite coherent with our usage of the terms. The
one by Bersen sounds a bit contrary to what we always conceived for
modality as something more related to user input, or possibly to user
perception,  than to information representation.

Concerning multi-device UI, it sounds more as a quality of the application
than of the interface. Distributed seems more purely related to the UI. Do
we remove Nomadic then?
