About the Moving Average
In our new program, it used the moving average theory to calculate the heart rate. So, I will introduce what is moving average theory and how it use in the program.
The moving average theory is a calculation to analyze, count data by creating a series of averages value of different subsets form the whole data.
At first, people would set a number of subsets, this number is always same.Use this group of subsets.to calculate the first element of the moving average. Then, the subset would shifting forward but the number of group of the subsets do not change. Use the new group of subsets to get the second element of the moving average. This process is repeated over the entire data series.
In the program, we use the moving average to calculate the heart rate. We only have three subsets and every time we only gay two peaks and use this two peas to get the heart rate. However, we get the subsets every frequently, it can ensure the accuracy of the heart rate.
