Problems solved by technology

However, the disadvantage of the Wi-Fi-based approach is that a pair of antennas is usually required, and the user needs to exercise between the antennas
In addition, Wi-Fi signals are easily interfered by environmental factors such as the movement of others

Embodiment

[0073] The performance of this method is tested by using a Raspberry Pi 4B, a circular array of 6 microphones, and an omnidirectional speaker to build a smart speaker prototype. Eight fitness users of different levels (5 males and 3 females) were recruited for the experiment. A total of 4 different indoor environments, a bedroom, a living room, a study and an office, were selected as experimental sites.

[0074] First, test the overall accuracy of the method in various situations. 8 volunteers performed 10 fitness actions in 4 different environments, and the smart speakers classified the user's fitness activities. image 3 Average precision, recall, and F1 scores for all classifications are shown. It can be seen from the figure that the accuracy rate in all cases is not lower than 93.24%, the recall rate is not lower than 93.80%, and the average F1 score is 96.61%, which fully shows that this method has high accuracy.

[0075] Then, test the performance of this method under...

Abstract

The invention relates to a non-contact fitness monitoring method using a smart speaker, and belongs to the technical field of mobile computing applications. The invention can realize the recognition of fitness actions only by relying on the loudspeaker in the smart speaker to emit high-frequency sound beyond the range of human hearing, and the microphone to receive the reflected signal, and to provide fine-grained fitness statistics and evaluation for users who exercise indoors. The method of the invention has low cost, strong anti-interference, no privacy leakage problem and good user experience, and is suitable for indoor monitoring environments such as homes and offices. The high-frequency sound adopted in the present invention exceeds the frequency of most noises in life, is not easily disturbed by environmental noise, and greatly enhances the environmental robustness of the non-contact fitness monitoring method. The present invention can monitor and evaluate typical fitness actions, and by combining deep learning technology and incremental learning technology, accurate action information can be obtained on a smart speaker with limited perception ability, and it has high accuracy.

Description

technical field [0001] The invention relates to a fitness behavior monitoring method, in particular to a fitness behavior monitoring method using a smart speaker, which is used for monitoring a user's fitness type and evaluating the user's fitness quality, and belongs to the technical field of mobile computing applications. Background technique [0002] Today, more and more people are beginning to pay attention to their health and body shape, and fitness is widely popular. Effective fitness can bring many benefits, such as increased muscle strength, improved body shape, and reduced risk of cardiovascular disease. However, due to the fast pace of life, going to a dedicated gym is inconvenient for many people. And getting a gym membership and hiring a personal trainer is often expensive. Therefore, many people start exercising at home / office, which is more beneficial to save time and money. However, due to the lack of effective supervision and professional effect evaluation...
