PT tracker stability settings

opentrack settings

1. lower the camera FOV to 56 deg; note one of two camera types are unable to work other than 75 deg.
2. use brighter LEDs.
3. use auto-threshold always. set it to slightly bigger (15 to 20%) pixel size than your LEDs.
4. for red LEDs, select "red only" in PT settings. if you have blue LEDs, report it as a bug and they'll be implemented.
5. bigger LEDs on the image are better than smaller LEDs. avoid zero gain, it works worse.

ps3 eye camera settings

1. play with camera gain until getting white LEDs with not much noise, and without excessive light bloom. always use full exposure, only change gain.
2. use a floppy filter as a circle stuffed from outside toward the camera lenses. may also use non-exposed analog camera film. bright background details may confuse the tracker about the point centers.
3. set color correction to all the same values, don't mess around with them at all.
4. never use 320x240. don't use 75 Hz for 640x480 as it corrupts the image. only 60 Hz and below give a clean image.

accela filter

1. never use "smoothing". it's gone in 2.4.0 and it doesn't work like you think.
2. don't exceed a deadzone of 0.06.
3. set rotation sensitivity to between 0.35 and 0.45
4. longer input range for yaw and pitch will make the movement move smooth overall, but it depends on sitting distance, screen size, and general comfort.
5. don't rely on "smoothing" at all. It's being removed. Only sensitivity (renamed to smoothing) and deadzone exist. It's completely gone in the next stable release (2.4.0).
