Initial results from the Chin Up Chapeau

Having made a hat to measure my posture as I walk around different parts of the city, I’ve spent the last few days testing it and getting a feel for what sort of results it produces.

Diagram showing position, direction I'm facing and the angle of my head. Click for a much larger version...

Pretty much exactly as I was expecting really, which is probably a good reason to avoid drawing any sweeping conclusions from it – at least until I’ve got to the stage where I collect data without being aware that I’m doing so…

On the plus side, it does reveal lots of unexpected things – posing yet more questions in the process – and that, I believe, is the sign of a good tool!

For these renderings, green represents a neutral head position, with the pointer getting redder as my gaze is lowered. Here are some noticings:

The lower, horizontal section shows me walking along a fairly busy road: eyes front, head direction and angle reasonably constant. The upper section is along a footpath next to a river: my interest is drawn in all sorts of directions and this is shown by the inconsistency in pointer direction and colour

Close-up of a high interest area - head angle changes a lot, as does the direction I'm facing

Head angle decreases slowly as I approach the High Street, but returns to a neutral position a lot quicker as I leave it behind me

High Street Mode gets switched off as soon as I go into the Post Office, on another day it fades slowly as I walk away.

It’s becoming apparent that I need to include some sort of calibration so that I can more reasonably compare tracks from different walks. Currently, differences in how I’m wearing the hat are too easily read as differences in head angle when I put all the traces on the same diagram.

I’ve also expanded the arduino code so that I log date, time, latitude, longitude, altitude, course, speed, bearing, pitch and roll. I think there are some very interesting potential correlations to investigate (for example: when my head angle decreases, do I also walk faster?) and, whilst I may not be investigating them right now, I want to make sure I’ve got the data when I do!
