Pervasive Computing (A Very Short Introduction) Nicola Dragoni Embedded Systems Engineering Section DTU Informatics Technical University of Denmark These slides have been found on the Web and adapted for this talk. Most of the original material is by Dr Andy Hunt, Electronics Department, University of York. 1 What s in this Room? Anything electronic which processes information Typically we find Mobile Phones PDAs Laptop computers Games consoles (hopefully turned off...) Mp3 players Any other info processing devices? 2 What Else is Here? Passive information storage Bank cards with chip-&-pin Products with RFID tag Anyone got a device inside?
