Hello! Here is how my €200 eye tracker has to be set up to avoid falling/rotating along the longitudinal axis. SC settings are shown on the other screenshots. I tried googling up some tutorials, but all of them got conflicting information, are inconsistent, and rely on "pushing the button to find out what it does" method. Afaik, no official guide is present, which is very sad when we are talking about two hundred of euros device's intergation. I do not wear glasses and facial hair. Got a sconce 35 cm above the display, so my flight place is lit properly. The distance between tobii and my eyes is: KB/M mode - 85-90 cm. Joystick mode - 125-130 cm. Tobii calibration with provided utility is possible only at ~80 cm or less. The issues is that I'm facing - blinking (which I do quite a lot to lubricate my eyes) leads to mild shaking in up-down direction even with Input Mix set to 1 (head only). This leads to my body trying to hold my head still, resulting in pain in the neck due to my muscles being constantly rigid. Also, being in the Vulture's pilot seat I cannot look down, even after manually recalibrating (got a button assigned to this function). Flying with the settings above reminds me a roller coaster ride to some degree with image always bouncing up and down, can't call in a pleasurable experience. All in all I feel some settings should be adjusted, unfortunately without an official manual from CIG I'm not able to do it on my own. Any advice?
