Eyex sampling frequency

[yangyangyang]

Now i have 2 devices run on 1 computer(including an eyex), which runs out of the CPU. The sampling frequency is lower just because of this. As a result, the accuracy
of gaze points becomes worse. i want to ask if there is any method to increase the
sampling frequency. What should i do?
Thank you. Please forgive my poor English.

Hi @yangyangyang,

The EyeX is designed to operate only one computer at a time and indeed the software only supports one eye tracker at a time, so I wonder what you are trying to accomplish?

Perhaps you could describe your hardware and software setup in more detail?

In any event, I cannot recommend having two eye tracker on one computer at the same time especially if both your eye trackers are using the computer CPU for processing.

Thanks for your help, Grant. But, one of the 2 devices I use is Tobii, while another is not. So they influence each other. If there is any way to increase the sampling frequency? Thank you.

Hi @yangyangyang,

Ok, thanks for the clarification! I am afraid the sampling frequency is requlated automatically according to computer hardware availability (which is rather high as Im sure you noticed)

So, unfortunately, I am left with my original advice to discontinue simultaneous use or consider upgrading the specifications of your computer.
