The most significant risks in regards to the pressure sensing is sensor inaccuracy. Specifically, while getting the sensors to work for a singular person isn’t difficult, but it is hard to adjust the parameters so that they are universally applicable. In order to mitigate this risk, Kaitlyn is tuning the sensors and updating the algorithm so that it is more general and work with as many people as possible.
The most significant risk for the neck angle sensing is that the gyroscope has too much drift and will effect the results over long periods of time of use, such as 1+ hours. In order to mitigate this risk, Lilly is doing additional calibration and fine tuning to the kalman filter which she is using to process the neck angle data.
For the browser extension, the most significant risk right now is getting the displays working seamlessly without the user having to click buttons in order to update data in the graphs. In order to update the graph displaying blink rate right now, the user has to click a button, which works well since Chrome extensions are event-driven. Cora is mitigating this risk by making it so when the user opens the browser extension, it automatically makes update requests so the user doesn’t need to do this themselves.
There have not been changes to our design nor are there updates to our schedule. We are trying to do as much testing right now as possible before the final presentation next week so that we can display at the very least functionality of our product during the presentation.
