Week9

These two pictures have larger components and can be seen more clearly.

Then I put the device on the shoes and did some foot gestures. As shown in Figure, sample IMU signals are collected. The series in the graph illustrate the fluctuation of four value in the quaternions while performing five different type of foot gesture, collected from three IMUs on the right foot. Some intermediate data processing is described in detail below.

Here are some raw output.

Then, I tried to visualize each IMU signal to check whether there is something wrong with each sensed IMU data.

Then, I visualized all IMU data togerther to align the timeline.
