This mobile app enables display, plotting, and storage of biosensor data from any iCalm sensor band. iCalm sensor bands are Bluetooth-enabled sensor bands that measure a variety of physiological parameters, such as galvanic skin response (a.k.a. electrodermal activity), 3-axis acceleration, temperature, and heart rate. iCalm is a mobile health project at the MIT Media Lab. This application and the sensor band hardware is intended for research and is available to project collaborators. Contributing authors: Olufemi Omojola, Mugisha Moshoka, Sharon Tam.
