Sensing Eating Events in Context: A Smartphone-Only Approach

Abstract: While the task of detecting eating events has been examined in prior work using a variety of wearable devices, the use of the smartphone as a standalone device to infer eating events remains as an open issue. In this paper, we propose a framework that infers eating vs. non-eating events from passive smartphone sensing, and evaluated on a dataset of 58 college students. First, we show that time of the day and features from modalities such as screen usage, accelerometer, app usage, and location are indicative of… Show more

“…), biosensors (heart rhythm monitor, skin conductance detector), Network adapters (Wi-Fi, Bluetooth), and environmental detectors (ambient pressure, temperature) are all examples of this type of sensor. Mood can be inferred from a person's location, physical activity (Bangamuarachchi et al, 2023), emotional state (LiKamWa et al, 2011), location (Müller et al, 2021) and social network using data from a variety of sensors (Meyerhoff et al, 2023). Multimodal sensing settings have been found to be more effective than using a single type of sensor, and understanding a user's environment allows for better-tailored, timely support (Barua et al, 2023;Turaev et al, 2023).…”
