The Tracking System Of A Three-Dimensional Position Of Hand Movement For Tremor Detection

The article formulated the basic requirements for a tracking system position of hand movement for tremor detection in three-dimensional space, using a touchscreen monitor. Execution of original dynamics tests on the touchscreen allows determining the trajectory of hand movement. The use of multi-colored markers circular shape on each finger and hand separately allows recording the coordinates of the points and deviation of its movement. Color markers are easily detected by computer vision algorithms. Color is used to separate the marker from the background, as well as to identify a specific marker of the finger from others. For segmentation of markers from the background, the segmentation method in the HSV space is used, which has advantages over segmentation in the RGB color space.
