Presence design, anyone who can explain?

When coming here, i was wondering "Presence design, what is that? Can someone give me a clue?". Even though i asked a couple of people about our course, the only answer i received was "ah, no, i have no idea, do you?". I thought so that this bleary part would be clear by the end of Monday.

Well, it's not! At least not totaly. So, filled with questions and food for thought by the lectures, i hope that I'll find out during this week. The only thing i'm sure of is that this is gonna be a really interesting week!
