Orientation tracking made easy

Hi all!

I recently released a tutorial and all the needed code to build an orientation tracker. I first thought about building this tracker when doing a course as a guest a while ago, so now it’s coming back.

I think the possibility to sense the orientation of things in real-time opens up a whole new dimension of possibilities in Physical Computing. Even more when it can be done wirelessly.

Tutorial and code is here: http://dev.qu.tu-berlin.de/projects/sf-razor-9dof-ahrs

Hope this will be useful,



The aim of this project is to provide a thorough review of the main types of sensing technologies used in musical applications. As new sensing technologies become available, this open space will provide an up-to-date resource for researchers in the field, complementing information available in books and textbooks such as Trends in Gestural Control of Music (Wanderley and Battier, eds. 2000) and Digital Musical Instruments: Control and Interaction Beyond the Keyboard (Miranda and Wanderley, 2006).

More than 30 techniques are described, along with their sensing principles and examples of actual devices that implement those principles. For each sensing technique, one or more devices are described with information on how to obtain them (links to distributors, prices), as well as photos of the device and necessary setup/conditioning circuits, circuit diagrams, one or more videos showing the devices used in practice, and finally, simulation circuits compatible with the software CircuitMaker.
