The Optotrak Toolbox
The following is supplementary information for the workshop Motor Control for Vision
Scientists which was held from January 7-11, 2004 in Lunteren, NL
as part of the EU-funded program Perception for Recognition and action
(PRA).The Optotrak Toolbox: Control your Optotrak from within Matlab.

The Optotrak 3020 (Northern Digital Inc.) is a widely used and highly accurate 3D motion and position measurement system. Traditionally, it is controlled using an interface in the C-programming language. Recently, I wrote a toolbox which allows to control the Optotrak from within Matlab. This has a number of advantages: (a) Matlab provides a flexible environment for high level mathematics, much more versatile than C. This is advantageous for the processing of the 3D data produced by the Optotrak. (b) There exist already a number of Matlab toolboxes for psychophysical experiments. Most importantly the Psychophysics Toolbox (mainly for stimulus presentation) and the Eyelink Toolbox (controlling the SR-Research Eyelink Eyetracker). The Optotrak Toolbox can be used to integrate the Optotrak with these other research tools. The Optotrak Toolbox is currently tested under Windows XP and Linux.
