Hi Nate,
Thanks for your information.
I notice that you use average eye position information as the head position. The eye position information is already supported by the old EyeX, the new 4C are supposed to provide exact head pose (X, Y, Z, Pitch, Yaw, Roll) See link
Do you have any ideas on exploring the newly added head pose data, and how does head rotation (Pitch, Yaw, Roll) help the cursor control, thanks.
