KinectX and KinectX Pro Potential and Limitations in Ultra Slow Motion Intelligent Training (USMIT)

Summary/Abstract: KinectX (KX) and KinectX Pro (KXP) are two specific applications for the training and evaluation of precision in body motion coordination. KinectX Pro was designed to provide an evaluation of efficiency of Ultra Slow Motion Intelligent Training (USMIT) for precision in motor coordination. KinectX was designed to provide direct feedback during the USMIT training in order to know the proper constant speed in ultra slow motions (10 mm/s). Material and method. 142 voluntary subjects participated in four sets of trials (a total of 657 tests): (1) preliminary tests (N=8); (2) motor coordination and psychological trait correlation tests (N=100); (3) precision progress in motor coordination tests (N=8); (4) motor coordination tests (N=27). Five advantages of KX and KXP were identified: (1) “no strings” movement; (2) “live” speed feedback; (3) trajectory feedback; (4) good sensor sensitivity (up to 30 evaluations per second); (5) easy relocation of KX and KXP systems. Two major disadvantages were identified and corrected during testing: (1) high sensitivityto light intensity variations; (2) high sensitivityto infrared radiations. One minor disadvantage: (1) variations inthe test results with variations in the subject’s position vs. sensor. Results. A guide for the optimal use of both applications was completed, tested and used in the trials. A beta version was completed for both KX and KXP and successfully used in the trials andthe training of athletes, members of the Romanian Olympic Team 2018. Conclusion. KinectX and KinectX Pro are reliable instruments in the training and evaluation of precision in motor coordination, based on the USMIT program.
