Hedrot (for "head rotation tracker") is a low-cost (less than 40 euros) and efficient open-source hardware/software solution for head tracking. Hedrot is especially suitable for binaural rendering (3D-Audio on headphones), and has been initially designed for use with the binaural renderer Bipan as part of the Bili Project.

All the protypes were built in Max. A C-library that ensure the serial communication with the head tracker as well as the computing of the angles has been specifically designed for this project. A Max external based on this library has been programmed and used as core of the main receiver program, which is available either as a Max patch or as a standalone application.

Contributions to help developing this collaborative project further are warmly welcome. Please contact us for proposals and questions.

We have developed seven externals for max, making it possible to callibrate single cameras and multicam setups, and use them for triangulating multiple points in absolute space.

Four of the objects are based on OpenCV, and all externals plus the maxpatch we used, have been posted to the forum hoping that it finds use elsewhere.

Max was used to track your face and warn you if it drops by a certain amount. The tracking was done using the cv.jit externals and the warning flash happens with the aka.booklight object.
