  1. Caitlin Lustig, Hristo Novatchkov, Lucy E. Dunne, Mike McHugh, and Lorcan Coyle Using Colocation to Support Human Memory

  2. Motivation • short term memory loss • aging population or injury • helping people live independently in their homes • technological solution? • research themes • smart homes • wearable sensors • sensor technology

  3. Technology Requirements • cheap • easy to install • low cognitive load • ambient • must work implicitly • comfortable • maintain privacy

  4. Radio Frequency Identification • commercially available technology • security, transport, asset tracking • passive/active tags • magnetically induced • very short range (~5cm) • small tags - stickers • static/mobile readers • reader is worn by the user • tags are embedded in the environment • less convenient for the user • cheaper, easier solution

  5. The RFID Glove

  6. The RFID Reader

  7. The Gumstix Computer • Gumstix • Linux OS • serial ports • WiFi • CF Card

  8. The RFID Glove

  9. Application Scenarios • detecting routine behaviour • interruptions • reminding users to complete routine tasks • spot a routine in progress • issue a warning if the task was incomplete after a delay • reminding users to take medicine • learning an activity model of medicine taking • ensuring that a policy is followed

  10. Evaluation • placement of tags • hard to ensure good read • spout, bowl, plate, knife • uncomfortable • too hot, too tight, too bulky, too delicate • impossible to make a fist properly • battery life • very short • RFID reader - 100mA, Gumstix - much higher

  11. Future Work • more complex and robust routine detector • remembering where you left something • “where did I leave my car keys?” • colocation rather than location • “you last had them with your mobile” • “you last had them yesterday” • alternative wearable solutions • pocket or purse RFID reader

  12. Conclusion • working prototype that tackles the application scenarios • simple small-scale evaluation • prototype implementaion was poorly received • alternative to a glove? • technology has merit • cheap • simple to use • works within limitations • private

  13. Questions/Discussion Thank you for your attention. Lorcan Coyle Email: lorcan.coyle@ucd.ie ODCSSS Website: http://odcsss.ie/ Project Wiki: https://secure.ucd.ie/twiki/bin/view/GumstixRFID/WebHome
