hello, i have a reasearch to analyse the movement of human walking using pca. i did it like this(adsbygoogle = window.adsbygoogle || []).push({});

1. i dibide the body into some part (thigh, foot, hand, etc)

2. i film it so i can track the x position of the parts

3. i get the x to t graph for every part

4. i make a matrix which column is the position x for every parts, and rows is the position for each time

5. i gind the pca of the matrix

question

how do i interpret the data?

what is the meaning of the eigen values?

what correlation berween first principle component and second principle component?

what further analysis can i get from doing pca?

thanks for the answers
