Hi @ashtraypot, thanks for your suggestion. As I understand it, you propose that the camera from the eye tracker be made visible to ShadowPlay? I am afraid that due to a number of reasons we are unlikely to implement such functionality in the near future. Most especially as the Camera the Tobii Eye Tracker uses are Infrared with focus on the eyes, so any images are unlikely to yield any useful information. In addition, camera images from the Tobii Tracker are not made available publically without a special licence to do so according to specific needs.
Apologies for the disappointing news, but I hope you understand our position in this matter.
