MUNDUS Environmental Sensor Framework

In the last decade, motion tracking with optoelectronic devices or inertial sensors has increasingly become the standard in therapy and rehabilitation processes for mobility-limiting diseases (such as neurological or orthopedic diseases). However, the use of existing solutions in a rehabilitation setting, for instance, is often too costly or time consuming, or poorly feasible due to size, weight, or fixation effort. For daily use in this special setting, low-cost solutions with a higher degree of flexibility are needed. In MUNDUS, we conceptualized, implemented, and evaluated a sensor system aimed at real-time object detection and tracking of a patient’s arm movements, which provided this information to the MUNDUS system in order to optimize movement strategies. The results regarding accuracy and data rate are promising, although they cannot compete with professional systems yet.
