  15. 15. bottom up innovation (‘push’)
  16. 16. •  ICT change power relations in (almost) all domains. •  Technologies can be understood as a trend amplifier. •  Can empower users of all kinds: citizens, consumers, workers, patients, audiences... (van  Dijk,  2010)   2011  
  17. 17. How to engage with users in order to adopt an active role in co-creation & co-design?
  18. 18. •  SOPA  &  PIPA  protest  [2012]     •  English  Wikipedia  +~7,000  websites  coordinated  a  service  blackout,  to  raise  awareness.     •  160  million  people  viewed  Wikipedia's  banner.     •  Google  collected  +7  million  signatures.   •  BoycoEs  of  companies  and  organiza1ons  that  support  the  legisla1on.

  20. 20. Clay  Shirky's  Cogni1ve  Surplus:  Crea1vity  and  Generosity  in  a  Connected  Age   reCAPTCHA    is  a  type  of  challenge-­‐response   that  ask  users  to  enter  words  seen  in   distorted  text  images  on  screen  (it   helps  digi1ze  the  text  of  books,  while   protec1ng  websites  from  bots).     The  system  has  been  reported  as  displaying   over  100  million  CAPTCHAs  every  day.  
  21. 21. New ideas that can be turned into applications that add value. The ability to collaborate between people: a) of different backgrounds (micro-contexts), b) with different perspectives, and c) possessing different knowledge. Human centric systemic innovation instruments (encouraging the interaction between all stakeholders).

  22. 22. (Pallot  et  al.,  2010)   Contextual & social based adoption & adaptation of ICT: •  Living  Labs  +  User  Driven  Innova9on  +  User  Centred  Design  +  User  Created   Content  +  User  Group  Experience  (socio-­‐emo1onal)   …BUT •  The  principles  (usability,  accessibility  or  technology  customiza9on)  are  more   manifested  in  theore9cal  considera9ons  rather  than  in  prac9ce.     •  Significant  number  of    “one-­‐size-­‐fits-­‐all”  paradigm  is  common  in  the  market.   ~40,000  solu1on  submissions  [~300,000  solvers  -­‐200  countries]  Awards:  $5,000  to  $1+M    
  23. 23. problems and challenges
  24. 24. Communications tools don’t get socially interesting until they get technologically boring (Shirky, 2008) Interesting social innovations may not be interesting technically (Bernstein, et al, 2011) Flash  mobs  strike  again  for  the  9th  annual  ‘no   pants’  subway  ride   Social  Media’s  Influence  on  the  Arab  Spring   Privacy  or  data  protec1on?  
  25. 25. (Bernstein,  Ackerman,  Chi  &  Miller,  2011).   Conflation of usefulness and usability Usefulness: asks whether a system solves an important problem. Usability: asks how users interact with the system. “In the technology industry many time features & functionalities is prioritized rather than usefulness” www.leapmotion.com hEp://theamazingios6maps.tumblr.com   ‘The  most  beau1ful,   powerful  mapping   service  ever’   iOS6                                                        Google  Map  
  26. 26. Challenge: How to create meaningful synergies between users & technology?   Problems  in  the  complex  innova1on  systems.       •  Suboptimal degree of interaction with users (i.e.  only  a  few   companies  effec1vely  involve  users  in  their  innova1on  process).     •  Discrepancy between theory and practice.  (i.e    early  involvement  of   users  par1cularly  in  early  stage  of  the  projects.)       •  Mechanisms to integrate increasingly multidisciplinary knowledge (gathered  in  diverse  interac1on  contexts)     •  Adequate translation and transformation of user insights (into  more  technical  requirements).       •  Path dependency& lock-in (i.e    difficult  to  break  into  new  grounds/ paradigms).     (Eriksson  et  al.,2005  and  De  Moor,  et  al  2010)  
  27. 27. (Fiedler,  2011,  Offenberg  &  Pipek,  2008;  Seserv.Org  ).     Future Internet research towards an “Open Development Model” different stakeholders combining efforts and benefit. conclusion Users at the center of the Internet Ecosystem
  28. 28. Usability is not enough to improve software poorly designed 1. High-flexible software architectures (from feedback to co-creation + cognitive surplus). 2. Legislation need to keep pace with the ever- increasing
  29. 29. 3. Systematic participation of users (iterative loop). 4. Cross-disciplinary methodologies (and knowledge integration tools to deal with complexity).
  30. 30. 5. Adopting various IPR models (providing more flexible uses). 6. Clear incentives (combining extrinsic with intrinsic motivation) I.e. pull-push
  31. 31. 7. QoE matters more than QoS to users. 8. Open to different cultures, languages (but localisation‐ friendly, context based).
  32. 32. 9. Increase transparency (but also awareness and simplicity) about data uses.
