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

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

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

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

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

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

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
