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

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

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

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

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

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

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

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

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

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

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? G. de Haan et al. - Opening up Closed Systems 12/12
