I'm intrigued by this. Most of my mobile typing is done with the Google keyboard swipe gesture thing. Is there a way to identify a user by this, since the words are entered in the form field one at a time? Also, accelerometer data as in the way the use holds the phone? I find it interesting because for the past week or so I've been trying to fix my bad posture, and as a result the way I hold my phone has changed drastically. I wonder how this type of system deals with situations like that.

I did not. I actually went to college in the south. I wonder how many participated?

We had a couple thousand people participate if I remember right. It was a moderately high percentage of the student body. This was 2014 era.

Interesting. Judging by the lines, we probably had a similar amount.

I wonder how many schools setup something similar? At least two I guess :).
