Reading “first step” you will miss a clear description of a device that is implemented into the building. We thought about a PDA-Like device that is used to interact with the building. On that way professors, janitors or chars can interact or can get information what to do.
The problem is: we do not want to give people an additional device. Furthermore the scenario “building tells people what to do” (e.g. please clean room X, please change the seat arrangement in room Y) is not really elegant. Isn’t it better (in an economic view) to do these things automatically – by intelligent furniture?
