This week I finalized the design of the computer stand by making a CAD file combining the platform jack design we selected last week with the linear actuators we selected a few weeks ago. I made holes in the off-the-shelf jack design to allow the linear actuators to flip over. I used OnShape for the CAD design.
I also began testing with OpenCV’s posture detection libraries. I used an off-the-shelf program on a video stream of myself and generated the posture landmarks for each frame. I then compared the positions of these landmarks to a “good posture position” which the user would make during the calibration stage. I think there is enough deviation in the landmark positions that a neural network, trained with enough data, can accurately classify between slouching and not slouching. Training the neural network will be done next week.
