Hi,

I've been trying to work with two TET devices at the same time. I have found that they seem to interfere when pointing to the same face. Should this happen? Does TET uses depth analysis by drawing a pattern of light like MS Kinect or is it only IR illumination?.


Thanks in advance,

Yes, the IR illuminators creates reflections (aka glints) on the cornea that's used to calculate the gaze point. If there are multiple sources the algorithms may have a hard time locating the pair that fits the specific device.
