Opening Keynote at UBICOMP 2010

  1. 1. Making dreams come true– or how to avoid a living nightmare <br />Morten Kyng<br />Computer Science<br />mkyng@cs.au.dk<br />With a little help from my friends/colleagues<br />
  2. 2. Dream?<br />Mark Weiser in Scientific American:‘Sal awakens: she smells coffee. A few minutes ago her alarm clock, alerted by her restless rolling before waking, had quietly asked “coffee?”, and she had mumbled “yes.”“Yes” and “no” are the only words it knows.’<br />From EU ISTAG: Road warrior<br />Personal communication device<br />Visa<br />Car rental<br />Traffic guidance<br />Personal settings for hotel room<br />
  3. 3. Or nightmare? <br />Mark Weiser in Scientific American:‘... A few minutes ago Sal’s alarm clock, alerted by her restless rolling before waking, had quietly asked “coffee?”, and …<br />From EU ISTAG: Road warrior<br />Personal communication device<br />Difficult if you don’t have a clue<br />
  4. 4. What is wonderful?<br /><ul><li>EU AAL 2004: Invisible computers
  5. 5. Difficult if you can’t sense and make sense</li></li></ul><li>What we have so far<br />We strive to create computing that excels among the best artefacts and enables everyday users to creatively appropriate this potential<br />Making such ubicom systems is difficult<br />We run the risk of making more complex and confusing systemse.g. obscuring the relation between action and reaction<br />Human action has a high degree of variability, fluidity and unpredictability<br />Errors will happen<br />Palpable computing is one approach to developing better systems<br />Palpability:supporting people in grasping physically and mentally<br />
  6. 6. Police, fire brigade, medics– The Tall Ships Races<br />Aarhus on 5-8 July 2007<br />6 x 3 km area of the harbor <br />800,000 people<br />Support for overview <br />3D map with overlays<br />Video cameras<br />Mobile phones withGPS & camera<br />AIS – Automatic ID System <br />
  7. 7. Overview prototype – The Tall Ships Races<br />
  8. 8. Overview prototype – The Tall Ships Races<br />
  9. 9. Naturalizing<br />‘literacytechnology’<br />electric motors<br />a walk in the woods<br />
  10. 10. Focus in human/technology relations<br />Technology focus<br />Introduced to new technology<br />Analysis<br />Fault finding<br />Exploration focus / mixed focus<br />Learning to use<br />Experiment<br />Modify<br />Activity focus<br />Work<br />Play<br />Doing: driving …<br />
  11. 11. Modes and qualities/capabilities<br />Technology focus<br />Discover computational resources<br />Inspect computational resources<br />Exploration focus / mixed focus<br />Cause-effect<br />Limited/reversible consequences<br />Combine, take apart, recombine<br />Activity focus<br />Resources should not thrust themselves on our attention<br />Confidence in correct operation<br />Going back<br />Overrule<br />
  12. 12. On Palpable Computing<br />Resource Awareness<br />Inspectability<br />Experimentability<br />Assemblability<br />Multiplicity<br />Adaptability<br />Resilience<br />Overruleability<br />
  13. 13. The Tall Ships Race<br />maps and photo draped over 3D<br />existing buildings<br />live geo-referenced camera feeds <br />live tracked personnel<br />boats expected positions<br />actual positions<br />compass and field of view<br />Temp bars, etc.<br />2D.<br />
  14. 14. Achieving palpability in use – developers<br />Example 1: The Automatic Identification System (AIS)<br />Planned + live positions of ships<br />Scaling down from 50 km radius <br />Inspectability, Assemblability and Multiplicity<br />Adaptabiluty<br />Experimentability<br />Example 2: The Geopath Dumper service<br />Storing GPS-tracked paths – to be used for de-briefing<br />
  15. 15. Picture of illegally parked car,visible in the Overview Prototype<br />
  16. 16. Achieving palpability in use – end-users<br />Officers have spotted a car parked on an emergency access route<br />Phone call & take picture<br />How and when to (dis-)trust technology when batteries run out<br />Picture position matches reported position<br />Phone rep “wobles” – this means receiving live signals<br />…<br />
  17. 17. How to improve systems and use<br />Design for Palpability supports different modes:<br />Technology focus<br />Exploration focus / mixed focus<br />Activity focus<br />
