Thom is continuing to work on programming the IMU to accurately detect position. He has familiarized himself with the IMU code and how the program we downloaded to calculate IMU position works. He has modified the program to use the value for pitch to give a binary value for head up or head down. However, we still have a lot of work to do in order to make this evaluation of “up” or “down” more precise and usable in an accurate setting, which is what Thom will focus on continuing to do.
We acquired a headband and some fabric, and Emma sewed a pocket into the headband to hold the IMU. Thom will be working to find the best position for the IMU in the headband - how best to wear the headband in order to get accurate IMU measurements. We received our new monitor for the Pi, and are now using it exclusively. On Monday, Emma and Katelyn experimented with the Bluetooth and audio capabilities of the Raspberry Pi, and successfully managed to get the Pi to play a downloaded .mp3 file through VLC player through the HDMI monitor, through the 3.5 mm headphone jack, and through Bluetooth earbuds. Katelyn’s next steps are to look at haptic motors that work with the Raspberry Pi and order haptic motor parts so we can try to get the Pi to control output. After that, she will be working to write code on the Pi to coordinate the Pi’s output of audio and haptics. We are starting to work on our V+V report, and hope to have most of it written in the next week or two. We may have to change our meeting schedule somewhat, as Katelyn will be out of town for the next four weekends. Comments are closed.
