I'm currently running an eyetracker experiment with Inquisit 5 and the data I've been getting seem a bit weird.
I've attached some data as an example.
In this dataset you can see that sometimes the pupil measures are seen as valid, but if you look at the actual measurements you can see that the same value is being repeated for multiple rows. One example can be found at row 468, where the same value is repeated for hundreds of measurements. Shouldn't this be tagged as an invalid measure?
Sometimes the validity code does indicate an invalid measure, for example at row 962, and there we also see the same value being repeated.
I'm afraid something is going wrong with the eyetracker recordings.
