Abstract
In this study, we develop a method for detecting the motions performed on a trampoline using an accelerometer mounted on a smartwatch. This method will lead to a system that can be used to promote trampoline exercise using a home trampoline by detecting motions on the trampoline using a smartwatch. We proposed a method based on the convolutional neural network to detect the motions on a trampoline. As a result of the performance evaluation by leave-one-subject-out cross-validation on eight subjects, our method achieves 78.8% estimation accuracy, which is the best estimation accuracy compared to the baseline methods. We also evaluate the inference time and the battery consumption when the model is actually running on a smartwatch. Our method is effective for on-device prediction.
Highlights
The demand for home exercise is increasing, as evidenced by the strong sales of Ring Fit Adventure [1], which combines games and exercise to provide continuous exercise
The model size of our convolutional neural network (CNN) model was the smallest compared to the other models because the filter size of the convolutional layer was small and the number of parameters was reduced by using global average pooling (GAP)
Even if we assume that the amount of time spent on trampoline exercise per day is at most 1 h, it is still within the range of normal use, even with the limited battery capacity of the Apple Watch
Summary
The demand for home exercise is increasing, as evidenced by the strong sales of Ring Fit Adventure [1], which combines games and exercise to provide continuous exercise. It is important to have a means to continuously exercise in a manner appropriate for one’s physical fitness. Trampoline exercise is perceived to be easier in subject evaluation than its equivalent exercise on flat ground, albeit the amount of exercise being the same [4]. Trampoline exercise is considered to be monotonous and lacks continuity. Some systems can be used to make trampoline exercise entertaining [6,7]. Some studies have developed systems to promote trampoline exercise [8,9,10]. These systems are not easy to use because they require visiting a facility or using a dedicated device, which takes cost for dedicated equipment
