Post-hoc fixation detection from a noisy eye-tracker signal.

[performlabrit]

...I should say that the scaling of the invisible target would reflect the threshold for fixation in angular degrees.

The downside to this is that one must set the threshold BEFORE running the simulation. In my experience, thresholds must often be specialized to the individual, and to the characteristics of post-calibration track quality.

I'm happy to chat with any Worldviz guys about this kind of thing! I hope that you guys are considering building this kind of functionality into Vizard itself. Not that many folks seem to be thinking about this yet, but the demand is surely going to increase over the next few years.
