This paper presents a platform for developing medical applications (PDMA). The platform is controlled by a microcontroller based microsystem and contains high-capacity local memory, GPS receiver, sensors and Bluetooth interface. The PDMA is modular and flexible, and can be extended with other sensors or modules to support the application effectively implemented. Using Bluetooth interface, the system can be controlled by a computer within an operating distance which is typically 10 m. For long distance control, the system uses the SMS service over a GSM connection. The PDMA can be connected to the GSM environment using a smartphone or mobile phone equipped with Bluetooth interface. The features of proposed system are demonstrated in an application for human fall detection and real time human tracking. Besides the interpretation of free fall signatures and the free fall or person status classification an important implemented feature is the reconstruction of the path walked by a person, indicating the direction and speed of travel.
