Why not use a table-mounted eye-tracker that leaves your electrodes in peace?

Hello,

I have experience with this eye-tracker. In my opinion is not well suitable for experiments with gaze tracking, if so, you need to write your own software for calibration and acquiring data from this device (the data format is simple).

The temporal resolution is well but spatial is only good in horizontal axis for vertical, signal is too poor. This follows from design of this device.

But the design is robust and well made and it is enough comfortable to use for long running experiments, where is needed a head mounted eye-tracker.

About the artifacts.

If experiments are performed in an isolated environment you may reduce artifacts in 50/60 Hz band (depends on localization) by powering the device with battery, otherwise you will always have artifacts in this bend.

I have used this system for some quick experiments in clinical setting. It is reliable, as we also correlated the outcome with search coil system. I agree that vertical eye movements may be an issue, but if you are interested in saccade velocity and dynamic properties of saccades, it should work just fine. There are no issues with horizontal system. The major drawback of this system is that it gives conjugate eye position (averages both sides - i believe). In this case, it is not an appropriate system to measure eye movements of a subject who has dysconjugate eye movements.

thanks,

Is that possible to upgrade preexisting Jazz Nove to Jazz integra binocular system?
