Eye-tracking with an external webcam

[metu]

Hi Jeremy,

I was wondering whether it is possible to run eyetracking experiments with an external webcam? It looks like PCIbex only detects the camera built into the laptops because even after changing Chrome’s default camera settings, the site still goes for the built-in one.

Is there a way to make the eyetracker work with external webcams?

Thank you

Hi,

I would have to look into how the webgazer library handles access to the webcam. Handling access to multiple input devices across web browsers is known to be surprisingly difficult. Maybe you can try with another browser (Firefox) to see whether it accesses the right webcam

Thank you for pointing this to my attention, I’ll let you know if I identify the cause of this behavior
