Clothing error

The software scan the test person’s clothing before they start a test, to automatically identify clothing that does not scan well due to the fabric or colour. The unsuitable items will be highlighted in red and white stripes, and should be removed or replaced in order to resume the scan. Some material or even topical creams do not produce very good recording signal, so they are rejected to preserve the quality of the data used for measures.

The sensor uses invisible infrared light rather than natural light and it sees the world differently to humans. So, unsuitable items may not be recognizable by the naked eye. Once the person has removed the clothing, press ‘Try again’ to calibrate the person again, and to see if the problem is resolved.

The clothing check occurs after the personal data is entered, but before the recording begins.


System error due to movement variations 

 
 

Ability of the test person to follow audio or video instructions

Ability of the test person to control movement voluntarily

Tracking error by the system due to: environmental factors, clothing or extreme/ unusual movements

Movement variation is for 3 main reasons:

 

The sensor can be confused by long hair, feet that are too close together, hands that are touching the legs, and limbs that are placed in the wrong position or cross over each other.

Movements that do not follow the instructions are recognised by the system, and the test person may be asked to repeat the task. Standardising the execution of the movement within certain boundaries helps to improve the repeatability of testing, and allows us to compare results between test. If the movement is not consistent with the basic instructions, the test person will have the opportunity to repeat the movement. After 3 attempts, the test person  will be asked to end the task or perform an easier modified version. If there is any doubt about the safety of a movement, the test person should ask for supervision or terminate the scan.  

Although individuals follow the instructions, it is natural to witness some degree of variation in movement, much like there is variation in tone of voice. Humans are not robots, so one should expect natural tendencies over time, but occasional variation.

The consistency of performance is enhanced by asking people to follow the instruction video before a recording begins. The test person is then familiar with the task required of them, especially experiencing the timing of the exercises.
