This week, I integrated Bluetooth into the tracking page and quaternion page. Now, we are able to start and stop the sensor tracking through the tracking page and store the data received from the Arduino in our database such that we can use them to create our visualizations on the quaternion page. I also worked with Sydney to properly parse the data received into usable data for the quaternion generation. I am slightly behind schedule because the algorithm is still being refined as we make changes to our data gathering. By next week, I should have the algorithm fully done to determine back curvature because I have also been analyzing the data patterns when a back is bent.
