Tutorial 3- Design Approaches

Yes, you can use User centered design (UCD) for pervasive computing but;

It is difficult to asses what a user needs if a user does not understand the technology that you are trying to implement. Also if it is something completely new how would a user know what their needs are. Then the fact some of the definitions collected for tutorial 1 suggested that users might not even know that they are interacting with the pervasive system.

Establishing requirements could rely on knowing an already present system and building upon it, and as UCD is based for desktop design there is a set context that the system will be using. If pervasive computing is implemented in everyday objects its context can change. So running something like a PACT analysis might not be successful.

Prototyping to get feedback off potential users can be a struggle to do in some forms of pervasive computing because if your running a system which contains many pieces of technology over a wide area a fully working model may be needed for users to understand what is happening.
