This is the online documentation for MOTOM

This toolbox allows you to initialise, configure and capture data using Northern Digital's Optotrak system, directly from Matlab. It has all the documented API functions accessible, but not all functions work properly, so I wrote convenience scripts and extra C functions to help with hardware and data handling.

Where do I start?

If you are a total newcomer to the Optotrak system, you can start by reading what it is and how it works, and then perhaps you could continue with the official documentation. Afterwards, you can read the API documentation, to see how different functions are implemented. Then, setting up the toolbox will be much easier. Of course, if you are not the RTFM type, you can head straight to the examples which will give a fair idea on how the toolbox works. You probably also want to calibrate your system so you can work in your own coordinate system and/or you use many position sensors in your set-up.
