Human Activity Recognition on Time Series Accelerometer Sensor Data using LSTM Recurrent Neural Networks
This work addresses human activity recognition for healthcare monitoring, but it is incremental as it applies an existing LSTM-ANN method to a new dataset.
The study tackled the problem of recognizing eating activity from smartwatch accelerometer data, achieving 90% success in identifying individual bites compared to other activities like smoking, medication-taking, or jogging.
The use of sensors available through smart devices has pervaded everyday life in several applications including human activity monitoring, healthcare, and social networks. In this study, we focus on the use of smartwatch accelerometer sensors to recognize eating activity. More specifically, we collected sensor data from 10 participants while consuming pizza. Using this information, and other comparable data available for similar events such as smoking and medication-taking, and dissimilar activities of jogging, we developed a LSTM-ANN architecture that has demonstrated 90% success in identifying individual bites compared to a puff, medication-taking or jogging activities.
