using pygaze in an head mounted system (glasses)

Hello all,

before deciding to dive into pygaze, I would like to know if it suits my requirements.

I wonder if I can use the pygaze library to track the eye gaze in a head mounted system, such as glasses. In other words, I would like to know if the library functions can be used with a camera really close to the eye.

Thank to all!

  • Hi Jeronimo,

    Conceptually, Pygaze doesn't care where the camera is, but it has implementations of a limited number of eye trackers. If the eye tracker that you use is not in that list, you won't be able to use Pygaze to record your eye tracking data.

    In terms of data analysis, I don't know whether Pygaze can be used for analysing data recorded by any eye tracker. I suppose it should be possible, as long as the data format follows certain rules.

    Regardless, the proximity of camera to eye is not really relevant to the question whether you can use Pygaze or not. For a list of eye trackers that Pygaze supports, check out this list here: https://osdoc.cogsci.nl/3.2/manual/eyetracking/pygaze/#supported-eye-trackers

  • Hi Eduard,

    thank you for the response.

    I would like to use a normal camera, for example a webcam using the USB of the raspberry Pi or directly the PiCam. So, as I understood, Pygaze can be used only with gaze eye trackers. Therefore, the library doesn't use frames from raw video recorder.

    I wonder to know how is the data which uses Pygaze (or where I could look for this information).

    Best regards,

    Jeronimo
