General Discussion • Jumpy pupil diameter

2016-11-25T12:16:20+02:00

Recently I discovered that the pupil diameter signal can contain artificial "jumps" which are well above the noise level. I guess that these "jumps" are caused by adaptive processes in the camera (automatic exposure control) and/or the eyetracking algorithm (adaptive threshold for pupil edge detection). The amplitude of the jumps seems to be very similar in one recording but can be different across recordings (different subjects, different conditions). The amplitude of these "jumps", I guess, depends on different individual pupil-to-iris contrasts and different levels of focus (also depending on glasses vs. contact lenses vs. no correction, even at the same eye-to-camera distance).
Obviously, having the exposure and threshold controlled adaptively is a good thing, but I wonder if we could have a "tracker" attribute in the API which allows us to freeze/unfreeze the currently used exposure level and threshold in order to get an artifact-free pupil diameter signal when this signal is of particular interest.

.
Pupil diameter of one eye over time. X:500ms/div, Y:2.5pix/div (where "pix" is the unit of "psize" as returned by the TET API).

C# • Running the Sample code

2016-11-23T14:30:20+02:00

Hi, I'm trying out the code samples provided on the Dev page and can't seem to get it working.

As far as I can tell, the OnGazeUpdate function never runs. I assumed there was something in IGazeListener that called OnGazeUpdate whenever the tracker had an update available. Should I add it to a delegate manually?

Java • Correcting Calibration Drift

2016-11-22T15:48:24+02:00

Hi,

My project which uses EyeTribe, the users are supposed to look at an image for a long amount of time. There seems to be a calibration drift after a minute or two of looking. I was wondering if there are ways to fix this?
Any hints and tips would be appreciated.

Thanks

Java • Drawing on an image using the gaze Coordinates

2016-11-05T17:19:46+02:00

Hi,

I was trying to draw the fixations on the image with a "X" to see the accuracy and the jitter but i was wondering how can I convert the gaze coordinates into the coordinates that java uses to draw? Or am I mistaken and they both are essentially the same?
I am trying something like
g.drawString("x", 409, 74);
These are one of the fixations I got but it doesnt seem to draw on the image.
Would be grateful if someone could point me in the right direction.

Thanks

General Discussion • Eye Tribe Connected but not working

2016-10-24T11:26:32+02:00

Hi everyone, I am using eye tribe but suddenly can not detected. It gives a message that your device has been connected but not working. Anyone who have an idea on how to resolve this problem, Actually, This is the second device I experienced the same problem. Maybe the Eye Tribe Company should reconsider this, the device is quite cheap but not durable at all. Its annoying, in the middle of experiment the device just stop working suddenly!! #feelingconfused
