Closing the Loop in Ambient Assisted Living – towards Feedback and Interventions to support health and emotional wellbeing Julie Doyle, Brian O’Mullane, Ben Knapp

The Research Problem – Closing the Loop in AAL• Research on sensor systems to monitor wellbeing and detect patterns of behaviour dominates the AAL research space• Closing the feedback loop - The challenge of – Predicting changes – Prompting positive preventative intervention measures has not been adequately addressed www.casala.ie

CASALA Research Overview• Unobtrusive, low cost ambient sensing in the home• Self-report daily health survey – ground truth data – Emotional wellbeing, quality of sleep, quality of social interactions, cognition, physiological measures• Determine statistical associations between self-reported health data with data gathered through sensors.• Support people in managing their health and wellbeing through feedback and interventions – Orange alerts vs red alerts www.casala.ie

The CASALA Living Lab• 3D CAVE -> Great Northern Haven -> 1000+ homes in community www.casala.ie

Great Northern Haven• 16 aware homes at Great Northern Haven, Dundalk, Co. Louth, supporting independent living• 100+ sensors in each apartment; 2240 sensors and actuators throughout the complex• 24-hour monitoring• Interactive technologies include connected TVs and tablet devices www.casala.ie

Monitoring and Detection through Sensing• Each apartment has 100+ sensors that detect – Presence – Flow of movement through the home – Use of electrical appliances – Home security• We can detect changes, and decline, in patterns of social, physical and cognitive behaviour and infer changes in emotional wellbeing www.casala.ie

Active vs Inactive Resident www.casala.ie

Monitoring through self-report• Daily health survey delivered through an iPad that measures – Emotional wellbeing - Positive and Negative Affect (PANAS Questionnaire) – Quality of sleep – Quality of social interactions – Cognition (daily trivia question)• Physiological measures including weight and blood pressure www.casala.ie

Providing Feedback• Information and intervention• Goal – early prediction of changes in emotional state; novel ‘human-in-the-loop’ intervention methods specific to an individual’s needs – Improve quality of life before problems arise• How can technology communicate our findings and help the person to adapt – how can it promote positive wellbeing www.casala.ie

Application Area - Wellbeing • User-centred design of applications • Preferences for reporting of wellbeing through textual questions, smileys etc. • Piloting of questions • Usability www.casala.ie

Application Area - Wellbeing www.casala.ie

Application Area – Home Safety– Monitoring the home environment and providing feedback – a closed loop www.casala.ie

Usage and Usability of Devices• Initial usage of devices for ‘fun’ – Helps to engage with technology• Weekly iPad class – Provides a social element – Residents showing each other what they’ve learned, helping someone with a problem – Devices easy to use; concepts more difficult• Technology on its own is not the solution – ‘Cultaca’ volunteers (‘support from behind’) www.casala.ie
