The application discloses a sports movement counting and rule-breaking action judging method based on human body posture recognition, and comprises the following steps: step A, human body recognition; step B, personnel screening; step C, repeated action detection based on human body key point detection technology; and step D, rule-breaking action judgment. The application uses human body key point detection technology of deep learning, calculates the relative position and relative angle of each limb part according to the position information, thereby judging what action the test personnel is doing, whether the action is in place, and whether there is a rule-breaking situation. Finally, in combination with time domain information, the preceding and subsequent multiple frames of actions are associated, and whether the human body accurately completes each standard action is judged. When each action is sequentially and normally completed, the system automatically counts. The application automatically adapts to different human body features, and compared with infrared radio frequency technology, the counting accuracy is high.

When comparing and analyzing multiple recordings of repetitive movements, there is no means to dynamically switch the reference point for synchronized playback. Therefore, it was difficult to recognize the discrepancies between movements that appeared different depending on the selection of the reference point, and to identify their causes. [Solution] The system accepts multiple time-series media data, each recording multiple repetitive actions, with multiple reference point candidates assigned to each recording. It displays these data in parallel or superimposed, and presents the reference point candidates on a timeline. For each type of reference point candidate, the system calculates the median time position across multiple recordings as the representative position, and sets intervals on the timeline using the midpoint between adjacent representative positions as boundaries. The system designates the reference point candidate corresponding to the interval to which the user's input location belongs as the reference point, and realigns all recordings to the time position of that reference point to update synchronized playback.

This brace will preferably consist of a flexible sleeve (1) covering the wrist and perforated for the thumb (2). One or more dorsal tunnels (3) (3') will be arranged on this flexible sleeve (1). One or more tunnels (3) (3') will be located on the palmar side of the sleeve (1). One or more flexible elastic strips (5) will be placed in these palmar and dorsal tunnels (3) or tunnels (3').

A method and system for augmented neurorehabilitation (ANR) for patients are disclosed. The ANR system generates rhythmic auditory stimuli (RAS) and visual augmented reality (AR) scenes, which are synchronized according to a common beat speed and output to the patient during a treatment session. Sensors worn by the patient capture biomechanical data related to repetitive movements performed by the patient in sync with the AR visual content and RAS. Critical thinking algorithms analyze the sensor data to determine the spatial and temporal relationships of the patient's movements relative to the visual and audio elements, and to determine the patient's entrainment level and progress toward clinical / therapeutic goals. Furthermore, a 3DAR modeling module configures the processor to dynamically adjust the augmented reality visual and audio content output to the patient based on the determined entrainment level and whether training goals have been achieved.
