A device-free future of ubicomp?

  1. 1. A device-free future of ubicomp? till.riedel #cosdeo2013 #ubicomp2013
  2. 2. Ubicomp was a lot about interacting with things…
  3. 3. …and we build cheap embedded devices …to hide sensing and computation everywhere and build infrastructures 3
  4. 4. Wearable computing was always the antithesis to the appliance-based approach It only became sexy because of the ubiquity of cheap infrastructure and powerful smartphones … but what comes next?? 4
  5. 5. applied dialectics Thesis Anti-Thesis Re-use existing infrastructure Reduce user instrumentation Enable novel contexts wearable device-free 5
  6. 6. Device Free vs. Device Bound Device-Bound Activity Recognition Sensor Device-Free Activity Recognition Sensor 6
  7. 7. So is „device-free“ the (next) future of (ubiquitous) computing? Thesis Anti-Thesis Synthesis 7 change conflict
  8. 8. The devices shall return…. • Organic Printed Sensor RFID • Will enable printing remote readable sensors/transducer • Device-free“ computation by (uncontrolled) Signal Superimposing • computation on the channel  up to 1000x lower energy, faster transmission for 1000 node net 8
  9. 9. a) device-free is a necessary next step! • New possibilities • New constraints • New thinking • New knowlege/views: • On RF-Channel • New Machine-Learning Tools • New Models • Complex interactions “The only thing we know about the future is that it will be different.” (hopefully) b) device-free != free of devices c) synthesis of approaches will bring real change 9
