The computer screen should be positioned directly above the sensor, and all devices should be horizontal, placed on a stable surface (table, tripod and floor), and at the optimal height from the floor. The scan area footprint should be a minimum of 3m wide X 4m long. To avoid confusing the sensor, there should be no random objects or people moving in the vicinity of the person being scanned, or between the sensor and the person.

Hardware arrangement



We recommend a neutral viewing angle, when the person is standing approximately 2.5-3.5m from the screen. The approximate distance between the floor and the bottom of the computer screen should be 150+/-20 cm, depending on the size of the screen. As a rule, the person being scanned, should be looking straight ahead at the screen during a scan - not excessively up or down, and certainly not to the side or at an angle.


The XBoxOne® Kinect sensor should be positioned between 80cm and 120cm from the floor. The sensor must be horizontal and the tilt adjusted to meet the onscreen Calibration requirements. The aim is for the sensor to see sufficient floor as well as the full height of the test person.

Posture Scan environment

The environment can affect the quality of the recording, as well as a persons ability to follow audio and video instructions. Please make sure the environment is optimised by considering the following:

Factors Purpose Dos Donts
Floor The floor is detected automatically during calibration at initial setup. The sensor needs to be positioned correctly to detect the floor and the person being scanned. Use a low profile, non-reflective, fabric mat that is at least 1m wide and 2.5m long. Uneven floor. Shiny floor. Shag carpets. Flooring that absorb/reflect light. Floors that move/ vibrate/shake
Lighting Direct bright light can interfere with the infrared light from the sensor and can negatively affect the scan results. Avoid bright light shining into the sensor. Direct sunlight and excessively bright light shining directly onto the sensor, the test person, the floor or the backgound
Intrusion of people System may start tracking the wrong person. A floor to ceiling wall at least 2m wide behind the person being tested. Clearly mark the scan area to avoid intrusion. Scanning where there are people in the vicinity of the test person. Calibrating with people in front of the sensor.
Space for the scanning station The ideal standing poistion for a scan is calculated by the software, and can be seen as a green box on the screen. There must be at least 1m of open space around the test person for a clear scan, and no other people visible on the screen for the duration of the scan. Test area should be at least 3m wide x 4m long. Use a floor to ceiling screen. Allow people to walk into or nearby the scan area. Stand too close to the back wall.

Unusual scan

If the scan results look unusual at any time, then it is important that the operator double checks the point cloud for errors. The ‘point cloud’ image can be made visible by clicking the 'dark cloud' icon in the menu bar of Movement Lab. Here is an example of poor scanning station environment - there is a combination of uneven floor, and a wall that is too close to the subject and not solid all the way to the floor. 

Factors Purpose
Gap near the wall Test in an area which does not have a gap in between the wall and the floor. This causes a waterfall effect.
Reflective wall Avoid mirrors or other highly reflective material on walls.
Poor floor detection Uneven and reflective floor surfaces can cause poor tracking. Use a carpetted mat on a flat surface to avoid issues with the flooring.
