The subject view presents the captured signal from the signal or as it was recorded to the file. The subject is presented in a frontal view and on a side view along side with some additional information.
A front view of the subject is presented on the left side of the screen. The front view can be presented using a silhouette (shown here in green), a skeleton model (not presented here) and a line model (presented as red dashed line). The presentation is
controlled from the settings file. At the bottom of the line, the lateral angle of the subject is presented (0.1 degrees in this example).
A side view of the subject is presented on the right side of the screen. The side view can be presented using a silhouette (shown here in green), a skeleton model (not presented here) and a line model (presented as red dashed line). The presentation is controlled
from the settings file. At the bottom of the line, the ventral angle of the subject is presented (-5.5 degrees in this example).
The 4 corners of the subject view show information to monitor the setup and the recording. The upper left corner shows the distance of the subject from the center of the field of view in the lateral direction. In the sway exercises, for example, the subject
should stand as close as possible to the center in that axes.
The upper right corner shows the distance of the subject from the kinect sensor . Different exercises call for the subject to be positioned at different distances from the sensor. For example, in the sway exercises the subject should be 2 meters away from
The lower left corner shows the frame rate in which the application processes the data coming from the Kinect sensor. This value should not deviate much from 30 frames per second (FPS). If the value drops it means that frames are lost and the recording should
be discarded. A slow frame rate can be caused by other programs running on the same computer or a computer that does not meet the requirements for the Kinect sensor.
The lower right corner shows the index of the current frame.
Ground capture quality
The bar on the right side of the panel shows the quality in which the application manages to capture the ground. Since all the measurements are done with respect to the ground, it is important to have an accurate measurement of it. Therefore, if the bar
drops and becomes yellow and red the quality of the recording might degrade. If this happens, the setup should be modified such that there is large portion of ground visible to the sensor, especially 1-4 meters away from the sensor.
