[Feature Request] Jaw Clench and Blink Data

Postby atomoton » Sun Dec 27, 2015 6:49 pm


Love the app. One thing I wish it had however was columns in the exported csv files for the jaw clench and blink detection data. As well as maybe the gyro data in an ideal world. It would help me filter out bunk data from my scans.

I have specifically chosen not included clench and blink, as I believe the algorithms used by Interaxon to calculate it are not very good. If the algorithms improve in the future then I will add them in.

I also experimented with the gyro data and decided not to include it. The reason for this is the position of the accelerometer. Depending on who is wearing the band, the sensor ends up at different points around the head and thus there is no way of telling proper orientation. On some people it does end up in the ideal position above the ear and thus the forward tilt axis, but in most it gets placed much further back around the head. The end result is you have no idea if a person is looking up and down, or tilting side to side.
