Abstract
The goal of this research project was to determine the feasibility of a wearable multi-sensor positioning device to be used as a training tool to evaluate rowing technique, and to determine the positioning accuracy using multiple mathematical models and estimation methods. The wearable device consists of an inertial measurement unit, an ultra-wideband ranging transceiver, and a global navigation satellite systems receiver. To evaluate the performance of the system, two experiments were conducted. The first experiment was performed in a controlled laboratory setting with a rowing machine at varying stroke rates, the purpose of this experiment was to validate the positioning algorithms and evaluate the accuracy of the results. The second experiment took place outdoors on a rowing boat. This experiment analyzed the rowing motion in multiple navigation frames and with various positioning methods. The results show that the wearable device is a viable option for rowing technique analysis, and the positioning accuracy can be achieved in the decimeter level with some of the methods and sensors.
