As usual, Thom is working on programming the IMU. The IMU program that we are using (found here: https://maker.pro/arduino/tutorial/how-to-interface-arduino-and-the-mpu-6050-sensor) accepts X, Y, and Z offsets, so Thom is working to determine how these offsets affect the measured pitch, yaw, and roll. He plotted the Arduino output in MATLAB, but the next step is to communicate between the two programs and get continuous processing. This will be useful for determining the correct offsets and for deciding how to process the data.
The ability to measure pitch, yaw, and roll will affect the placement of the IMU on the head. We currently are planning to position the IMU on the side of the head, since it is difficult for people to wear headbands such that part of the headband is flat on top of the head. Although we are not currently sure how to make this happen, we would like to have some sort of zero button to reset the IMU position. Ideally, this zero button would help compensate for slightly different positioning of the IMU on each person’s head and for different levels of ability to raise the head fully. Emma is currently working on the V+V report, and has been going through our list of device specifications to determine how we could potentially test each item. As she goes through the list of specs, she is keeping track of questions that come up. We plan to meet with Dr. Klaesner within the next week in order to get our questions about the V+V report cleared up. Katelyn contacted our client, Dr. Courtney Dunn, with updates on how our device is going and with some questions. The questions and answers are logged in LabArchives. She also is looking into the use of haptic motors with Raspberry Pis and has been taking care of moving our Google Drive notes into LabArchives and other small tasks. Comments are closed.
