If you have difficulty moving the calibration disc displayed on the screen or can't get a calibration score above 80,please try the following:
Click "Pause tracking" in the Leap Motion icon menu.
Click “Settings” in the Leap Motion icon menu to open the Leap Motion Control Panel and start the calibration utility from the Troubleshooting tab.
Click "Resume Tracking" in the Leap Motion icon menu when you are done.
While performing the calibration process, rotate the controller to move the calibration disc so that it "paints" the window. Moving the Leap Motion Controller up and down or side to side does not adversely affect the calibration, but calibration requires rotation.

If you are unable to get the score above 80, please try recalibrating your controller on another computer and with a different USB cable. If that does not help, please contact us.
