This week was spent working on the design presentation. There were a few gaps that needed to be addressed afterwards, which included how we were planning on calibrating our device and the feasibility of our hardware and software communication plans.
We discussed and narrowed down our approach to potential two methods. One would be to place the “hardware pen” onto the ground as a reference point in the beginning to serve as the start. This, however, may potentially cause calibration issues due to increased drift and may require the inconvenience of constantly having to place it on the ground to refresh the starting point.
The other one would be to place another device on a static spot as a reference point for the pen’s movement in the air. This may reduce the issue of drift, but will also require the inconvenience of having more equipment which would increase the cost of our project and make it less user-friendly. We will likely need to discuss with our advisors to see which one would be a better approach in the long run.
