In NITE versions before 1.5, the user had to stand in a calibration (“psi”) pose before the system could build his skeleton. Now the skeleton can be created shortly after the user enters the scene.

To enable this for 1.5.4 version, create /usr/etc/primesense/Features_1_5_4/FeatureExtraction.ini

with the following settings: [FeatureExtractor] AlwaysRunCalibration=1 AutoBodyParameters=1 UseAutoCalibration=1

[Generator]
;Preference=Quality
Preference=Speed

Limitations

- Auto calibration works on standing users. A sitting user will not be 
	calibrated automatically.
- Most of the user‟s body should be visible in order for the automatic 
	calibration to take place.
- The user should be located further than ~1m from the sensor in order 
	for the automatic calibration to start.

Recommendations

The following recommendations will help to complete the calibration faster and achieve better results. The recommendations apply to the auto-calibration phase only (first seconds of the user in the scene) and not to the subsequent frames. - The user should be facing the sensor and standing upright. - The hands should not hide the torso area. - The user should avoid fast motion
