I had a working prototype, so I wore it to work in a shirt pocket and kept a log of my observations and what I want to change in the programming. The two big takeaways were that the device should recognize when it has pointed at the origin, and I would like to experiment with vibration patterns. The origin will probably be geographic north, and it is safe to think of it that way.

The first technique for vibrating recognized when the device was in a window of acceptable readings. In this case, it was plus or minus five degrees from the origin, zero degrees, which was an excellent start, but it was imprecise by its nature. My next try will recognize when it is turning toward the origin, and buzz when it senses it has crossed it. Doing it this way may lead to a slight delay.

Throughout the day, I saw cases where it would have been useful to have a unique buzzing pattern. For example, when I start or reset, I would like to know when everything is running instead of waiting a long time and assuming it is ready. If I can get enough unique patterns, I may even be able to tell the user which direction they are facing instead of just north.
