To avoid some potential confusion:
Most modern IMU sensors are supposed to offer “9 degrees of freedom”.
(Directional 3-axis information from accelerometer, gyroscope and
magnetometer.)
If refering to tracking, you speak “just” of 3DoF (orientation) or 6
DoF tracking (orientation + positional data).

(for example)
Best,
Stefan
P.S.: 9 or 10 degrees of freedom certainly sounds better than 6DoF...
(Of course this is the raw sensor data before fusion, which probaby
will give 3DoF orientation data as result. It could be discussed if
quaternion orientation is 3DoF or 4DoF, though. If 4DoF, an OHTI 6DoF
pose would be rather 7DoF... I refuse to take part in the following
discussion about 7DoF tracking, which means once more: I’m out! 😉)

Citando Bo-Erik Sandholm <bosses...@gmail.com>:
The ohti Projects for a open headtracker has been slow but will hopefully
be updated soon.
It is only for so called 9 degrees of freedom, no position data only
directional info with 2 degrees precision.
Data is currently quaternions over serial communication to control the
omnitone binaural decoder.
The host software written in JavaScript could with a bit of help have the
added functionality to send OSC.
There already exists a library to send OSC for JavaScript.

Hi Jack,
Yes, I saw those Bose but inertial sensors won't work for precise tracking.
I've done a lot of arkit/arcore with phones and tablets and it works great
but I don't want to be looking through a screen with a 2D representation of
the world while experiencing a sound only environment (unless you strap the
device to headphones with the camera facing forward, but that would be not
very convenient).
Cheers,
Hector

The new Bose headphones have 6dof tracking, but the accelerometers are
not
terribly accurate, so they are more 3dof really, unless you implement
ARKit
or similar.
