Doppel Inc. is a Canadian startup based in Waterloo, Ontario, focused on the development of wearable fitness devices for athletic training. Doppel is creating a wearable fitness device that tracks repetitions for CrossFit athletes. In order to promote compliance, engagement and competition within the class, the results are displayed on a scoreboard in real time, and made available online for users to access. Doppel has developed a device for the on-line tracking of movement during exercise, based on an IMU built into a belt-like neoprene band, attached at the chest level (like a heart rate monitor), which transmits data via bluetooth to a central device. In order to enable the online counting and display of exercise repetitions for each participant, the system must be able to accurately identify the starting and ending point of each repetition from the continuous time series data measured by the IMU, a problem known as temporal segmentation. The aim of the proposed research is to develop and validate an accurate and robust segmentation algorithm which is capable of accurately generating the required repetition data for the CrossFit exercises.
