Overview of our strategy for in-home localization and kinematics monitoring. (a) In-home localization approach. Bluetooth transmitters are installed around the home, and the received signal strength is monitored at the patient. The localization provides context to the captured activities. (b) Minimal sensor set that is unobtrusive during daily life, including IMUs worn on each wrist and the waist, and a Bluetooth receiver worn at the waist. (c) Kinematic reconstruction of the torso derived from the worn IMUs.
