Abstract:

Smoking is the leading cause of preventable deaths. Mobile technologies can help to deliver just-in-time-interventions to abstinent smokers and assist them in resisting urges to lapse. Doing so, however, it requires identification of high-risk situations that may lead an abstinent smoker to relapse. In this paper, we propose an explainable model for detecting smoking lapses in newly abstinent smokers using respiration and 6-axis inertial sensors worn on wrists. We propose a novel method by identifying windows of data that represent the hand at the mouth. We then develop a model to classify into puff or non-puff. On the training data, the model achieves a recall rate of 98%, for a FP rate of 1.5%. When the model is applied to the data collected from 13 abstainers, the false positive rate is 0.3/hour. Among 15 lapsers, the model is able to pinpoint the timing of first lapse in 13 participants.
