When Trackir is fully supported with 6 DOF, it's supposed to have a seperate input to keyboard/mouse/game controller. Dayz should support mouse/keyboard/game controller and natural points track ir. It currently does not. This is how it is in arma https://i.imgur.com/km3nROC.jpg no such thing in dayzs UI, t only has 2 columns, 1 dor m/k and the other for a game controller

DEFAULT TRACK IR AXIS

YAW - look left/right (look left and right with player / in vehicle)
PITCH - look up/down (look up and down with player / in vehicle)
ROLL - roll left/right (roll left and right with player / in vehicle)
X - lean left/right (lean left and right in vehicle)
Y - height up/down (adjust head head up and down in vehicle)
Z - zoom in/out (variable fov zooming in and out with player/controller)

Some of these axis can be re bound to suit other functions instead like leaning forward and backwards in a cockpit instead of using it as variable fov function. https://i.imgur.com/r4I3Ot2.jpg

Newly introduced track ir is not supporting any of these inputs/fuctions. It is using mouse input for yaw and pitch as these are the only available axis in game currently or in the ui at least. This causes jitter and an incorrect way to support trackir rendering it useless. and eye straining.

if you go into controls and then try binding Track IR Roll to in game lean left/right bind (roll) it uses the keyboard input (Q/E) When binding track ir, it should function as a +/- input on the same axis for left/right/min/max with incrmental analogue movement between the animation. Instead it is like this.. https://i.imgur.com/CvcTOot.jpg Either hard leaning or straight, no movement in between the animation.

There is further implications with track ir and player controller. Track ir is disabled when ADS and using inventory tab. Very jarring when looking left, open inventory and then snap to center. Leave inventory and then snaps back to where I was looking originally. This is confusing and frustrating for the brain to handle due to the nature of how track ir works.

Some actions like flare usage using track ir is odd and not functioning how track ir should. due to the new controller and inertia. Looking around causes character to move the flare whre I look instead of my head following where I look. This is the best scenario I could capture to get an example of what is a hppening with track ir and the jitter caused.

Track ir is for head movement only, some things like flare should be controlled by mouse only (hence why trackir is using the mouse input. and this happening)
