When using the TrackerPro 2, sometimes the cursor may not move to the center of a screen. This is normal and can happen over time, as the TrackerPro is tracking the reflective dot it sometimes readjusts to pick up movement. A process called “bumping” allows you to re-center the mouse cursor when needed.
"Bumping" is a simple process, that allows you to reposition the mouse cursor to the center of your screen to match your physical position. To do this, move the cursor to one edge of the screen until it stops, or “bumps”, against it. You may need to move the reflective dot slightly outside the normal space, as what you're doing is making the camera lose sight of the reflective dot for a few seconds, then pick it back up when you move back towards the center. Continue moving with small up-and-down or side-to-side movements at the edge of the top/ bottom and left/ right of your screen until the mouse cursor is positioned to your liking.
Another option, if you have some assistance, is to have someone hold their hand over the camera lens of the TrackerPro and move the cursor to the center of the screen. Then, ensure the user is looking directly at that screen with a reflective dot. Once the person removes their hand from the TrackerPro, the reflective dot will be recognized and should now be centered.
