Multimodal Indoor Social Interaction Sensing and Real-time Feedback for Behavioural Intervention

I delivered this presentation at the ACM Workshop on Wireless of the Students, by the Students & for the Students, in September 2015 in Paris.

2. Social Interactions are Important for many reasons • Informal team communication correlates with performance and efficiency (Pentland et al.) • Shared spaces and the location of good coffee encourages inter-group mixing and innovation (Brown et al.) • Communication patterns help in developing an understanding of disease spreading (Yoneki et al.)
3. What you don’t say matters as well
4. What you don’t say matters as well • High-power postures induce elevated testosterone, decreased cortisol and increased feelings of power… • … and help you during a job interview!
5. Social Interactions are difficult to measure • Ethnographic Methods • Do not scale • People forget • People feel observed
6. Technology is not there yet • Low spatial and temporal granularity • Data every few minutes up to 10 meters • Ad hoc hardware • Instrumentation of the building
7. We already wear many useful sensors • Explore the capabilities of wearable devices • Always co-located with the user • Simplified deployment • BLE + Inertial sensors
8. Awareness is not enough • Research mechanisms for body language feedback • Discreet feedback channels • Vibration • Thermal • Electrical muscle stimulation
9. Preliminary Results • Explored Bluetooth Low Energy to monitor fine grained proximity • 2.5 meters and 3 seconds spatial and temporal resolution • Dynamic parameters adaptation to improve battery life
10. What’s next? • Devices currently deployed at Spacelab Ltd in London • Experimenting with BLE and smartwatches
11. Thank you Alessandro Montanari alessandro.montanari@cl.cam.ac.uk
