Safe Sleeve
Jake Cordover
One Sentence: Safe Sleeve is a soft, functional sleeve that conveys biomechanics that have historically been confined to clinical settings or cost prohibitive motion capture equipment.
Weekly accomplishments: This past week, I implemented Professor Ponto’s recommended implementation. This was a much simpler approach, without quaternions or Euler angles, but the data looks pretty good so this will probably be the chosen implementation for the final project.
Otherwise, I spent some time trying to get Bluetooth working— one sensor connects, but the other doesn’t so I’m trying to figure out why that’s the case. Additionally, I have begun work on a simple app for data visualization.
Images:
Below is the simple visualization app. I would like to add a line graph plotting knee angle vs time in the bottom right of the tracking screen. When the current angle of the knee crosses the threshold set the screen turns red, otherwise it is green.

Areas of concern: Now that the data looks much better, my biggest concern is getting the second Bluetooth sensor working.
