Opening up Closed Systems | de Haan, Choenni & Mulder

  1. 1. Opening up Closed Systems with Sensible Data Geert de Haan, Sunil Choenni, Ingrid Mulder Communication, Media and Information Technology (CMI) Rotterdam University (HRO) G.de.Haan@hro.nl
  2. 2. Content   User Centered Design   Human Centered ICT   Data in Sensitive Environments   Structured and unstructured data   Museum e-Guide example   Conclosure G. de Haan et al. - Opening up Closed Systems 2/12
  3. 3. User Centered Design - UCD   design aimed at a user group   usability design principles (ISO)   focus on interface usage as a tool   tool perpective   usage as development proces   status and image   social interaction G. de Haan et al. - Opening up Closed Systems 3/12
  4. 4. Human Centered Design   changing field of application 'market'   consumer, peers   away from business procedures   at home and everywhere (mobile, ambient, ... )   different perspectives   social interaction   ict as a mere technique   user experience design G. de Haan et al. - Opening up Closed Systems 4/12
  5. 5. Human Centered ICT   ICT to facilitate social interaction   emergent technologies   sensitive environments   intelligent infrastructures   LivingLab G. de Haan et al. - Opening up Closed Systems 5/12
  6. 6. Sensitive Environments   RFID   Bluetooth   ZigBee   WiFi   Infra-red   environment sensors - eg movement   biosensors - eg heart rate G. de Haan et al. - Opening up Closed Systems 6/12
  7. 7. Data in Sensitive Environments   Structured data (DBMS) makes sense within the Closed World   Semi-structured data (XML)   Unstructured data (Text) makes sense but uncertain, unreliable G. de Haan et al. - Opening up Closed Systems 7/12
  8. 8. How to create surplus information   use closed-world data to make real-world data reliable   use real-world data to make closed-world data interesting   use multiple sources to improve usefulness G. de Haan et al. - Opening up Closed Systems 8/12
  9. 9. Museum e-guide example - UCD   How to provide guidance information about a work of art at the right level of expertise. UCD / tool perspective:   ask users to specify the art-work and the expertise   a more button   an interest profile card G. de Haan et al. - Opening up Closed Systems 9/12
  10. 10. Museum e-guide example - HCIct HCIct / sensing perspective:   get art-work from a beacon   get expertise from time at a beacon   get interest profile from time at sets of beacons Multiple source perspective   add expertise from movement patterns at various beacons   add interest profile from sources on the internet G. de Haan et al. - Opening up Closed Systems 10/12
  11. 11. How to get semi/unstructured data   keyword matching   user profiles   web-crawlers   metadata   semantic analysis   relations may not be strong but there are many   may not be very reliable but they are free   the more sources the more useful the information G. de Haan et al. - Opening up Closed Systems 11/12
  12. 12. Conclosure   Human Centered ICT   sensitive environments   intelligent infrastructure   real-world makes closed-world data interesting   closed-world makes real-world data reliable   multiples sources make data useful   Thank you! / Questions?
