Challenge
How can we use real-time information to influence behaviour (for the good)?
Key Stages
How to model and reason about behaviour?
How to influence behaviour?

Assisting Older Drivers
• Can data analysis determine long-term issues?– cognitive impairments
• Short-term problems– effects of drugs
• Suggest the need for assistive technologies

Can we use pervasive technologies to allow people to stay longer in their own homes?
Supporting people with dementia
• People in the early stages of dementia want to continue living at home.
• They have problems with:– episodic memory – executive control (planning,
sequencing, attentional control)
“Gets the kettle, fills it, switches it on…But then she’ll stand there, and I’ll say – ‘what are you doing now?’ and I’ve jogged her memory again…She gets the coffee jar, and she’ll take the top off the jar. And she’ll look at it and think ‘what am I doing with this off for?”

Personalisation• Influencing requires personalisation• There has been recent work on algorithms to
analyse vast amounts of data– e.g. collective intelligence, web analysis
• Assumptions behind most of this work:– no privacy issues– results not needed in real-time
• More focus needed on personalisation & timeliness– presenting useful information, in real-time, observing
privacy
Scalability
• Real-time data pattern matching & processing complex event processing?
• Historic Analysis cloud?

Summary
• Real time data increasing– Sensors– Software as a Service
• Key is to extract value from this data by understanding the real-world behaviour it represents
• Grand challenge is to use this information to influence behaviour (for the good)
