I am writing a Java3D virtual environment for use in brain recordings. A really critical aspect of this experiment is eye tracking. In that past, we have used a dos based system with a data acquisition card. I want to replace it with something that is integrated into my Java3D task. The brain data is acquired on a separate bank of computers. We need to know where in the environment the monkey was looking at all moments. My questions are: Is there an existing eyetracker that works with Java3D? If not, how do I access the data acquisition card from my program (I know this is more of a general java question)? Should I write a Native Interface that runs on a thread? Timing is a critical issue and I need accuracy of < 1ms if possible. I was thinking that JMF's Time object could be a good way. Thanks for any advice.
