Thank you. I have a couple of additional calibration questions. When the calibration first starts, you get the screen where it shows two dots/circles for your eyes. I’ve noticed that as I move closer/further from the 4C that the size of the dots gets larger. I assume that the point at which they are the largest is the ideal distance. Is that correct?

I also have a question about ambient light. Is it better to be brighter or dimmer? As I understand it, the tracker uses IR to bounce a beam off the back of your eye and this is detected by a standard vga camera (the same one used by Windows Hello)? When I’m gaming I light to keep the ambient light reduced, but I notice when I try to use the Windows Hello stuff that the image of my fat face that it shows me is very dark and needs more light. I’ve only gotten Hello to work sporadically, and I think the ambient lighting is the issue. Do you have any better guidelines for ambient light and where it is best to be located? Would a light background on the monitor work better for illumination in Hello than one of the darker ones?

One final thing, I promise. I play F1 2017 and can’t have the monitor as close to my eyes as the Tobii requires. So I built a stand to which the 4C is attached, and that sits about eight inches in front of the monitor. It seems that I can get a reasonably accurate setup if I use the setup screen where you adjust the bar to match the lines on the Tobii and vary that alignment. Basically, it’s trying to fool the 4C about the size of the screen. This may actually not work, but it SEEMS to work because in a driving game you’re focused primarily on the center of the screen anyway and the range isn’t that great (there’s usually not much to see at the edges of the screen). This may all fall apart with a FPS where accuracy is more critical.

Okay, that’s enough. I’ve taken enough of your time. Thank you in advance for the previous info; that was very helpful and it might merit a write-up on your website that describes the calibration process. Just the fact that it’s not learning from trial to trial could save someone a lot of time and frustration.
