We investigate just-in-time interventions to support behavioral change for emotional eating. Our approach is to use both mobile phone applications and physiological sensor data to detect an emotional cue from the user. We then describe a system to provide just-in-time intervention before emotional eating occurs. In support of this exploration, we show that self-identified emotional eaters are motivated to track their emotions longitudinally, at least over the course of several days, that they will also track their eating behaviors, and that they would use a just in time technological intervention via their cell phones. We also show that it is difficult to track emotions with wearable sensors “in the wild,” although we did make progress in this regard.
