Tobacco is the only legally available consumer product which kills
people when entirely used as intended. Quitting to smoke is however
extremely hard. This project is about quantifying one's personal smoking
behaviour in an inconspicuous way. A smoker can gain insight into his
smoking triggers, gain more insights about his addiction and get
personalized smoking cessation material.
We investigate different ways of tracking smoking behaviour. Using
inertial sensors worn on the wrist, its motion allows to detect typical
hand-to-mouth gestures. This is even possible for multiple days on a
single battery charge. Alternatively a Smart Lighter, a lighter that can
track whenever it is lit, provides the same data without having to wear
a sensor on the wrist.
The gathered smoking data is used to provide personalized smoking
cessation information on a mobile device. This includes personal
statistics, but also information which led others with a similar profile
to reduce or quit smoking - efficient smoking cessation material can be
detected automatically. The objective quantification of smoking
behaviour is also used to test the efficacy of smoking interventions.
