Abstract

Monitoring the mobility of people with physical disabilities is an important part of rehabilitation medicine. A Wearable Mobility Monitoring System (WMMS) that can monitor mobility within the home environment and the community for a long period could be a valuable tool for the clinical professional. Current available technologies, such as small accelerometers and the new generation of Blackberry handheld devices, provide a great opportunity to create such a system. This paper presents preliminary research on a proof-of-concept system that evaluates the BlackBerry as a WMMS platform. For this pilot study, a simple biomechanical monitoring system was created using a commercial human motion capture system, the Xbus kit from Xsens Technologies. Java software was written for BlackBerry 8800 to log and process real-time orientation data sent by the Xbus Master via Bluetooth connection, and also to log GPS coordinates and the GPS data acquisition time. This pilot project provides insight into the data logging expectations for a Bluetooth connection over typical BlackBerry devices and real-time programming issues with WMMS applications.
