The goal of this watch app is to use the accelerometer of the watch to measure real-world distances between button presses, using a high sample rate during measurement. Additional functionality/methods for measuring is planned if the lack of gyroscope and the error introduced from double integration proves too great for this to be remotely reliable.
The motivation for this is for estimating dimensions - rooms, yards/lawns, camping sites, game fields, etc. without needing to carry anything extra, and to get some familiarity with using the accelerometer (as I'm already familiar with the other pieces, having written a fairly involved watch face, Timely
As the development period doesn't officially start until tomorrow at 1pm EST, I'm focusing purely on planning/theory/research right now - keeping track of it in Trello here
2014-08-15, 1PM EST:
- Add additional methods for measurement (pedometer/counter, etc.) and ensure settings page is in place, then resume algorithm work.
2014-09-05, 5PM EST
- Publish final code to github and final app to store, sanity check, confirm/test all functionality until the 8PM deadline.
Thoughts/comments/suggestions welcome, especially from anyone who's dared to try to use a single accelerometer with no gyroscope to double integrate and approximate distances
