2. Using Colocation to Support Human Memory2 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. Using Colocation to Support Human Memory3 Technology Requirements cheap easy to install low cognitive load ambient must work implicitly comfortable maintain privacy

4. Using Colocation to Support Human Memory4 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. Using Colocation to Support Human Memory5 The RFID Glove

6. Using Colocation to Support Human Memory6 The RFID Reader

7. Using Colocation to Support Human Memory7 The Gumstix Computer Gumstix Linux OS serial ports WiFi CF Card

8. Using Colocation to Support Human Memory8 The RFID Glove

9. Using Colocation to Support Human Memory9 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. Using Colocation to Support Human Memory10 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. Using Colocation to Support Human Memory11 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. Using Colocation to Support Human Memory12 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
