An intelligent ball passing system is provided, including: a ball passing robot configured for carrying out a ball passing action according to human body postures, including: a video capture device (1) configured for acquiring human body posture data, a movement mechanism (2) configured for driving the ball passing robot to move according to a ball passing instruction, and a central processing module (3) connected to the movement mechanism (2) and the video capture device (1) respectively; and a software system configured for controlling the ball passing robot to carry out the ball passing action, the central processing module recognizing and classifying the human body postures by using the software system that uses a BP neural network.

Systems, devices and methods are provided for acquiring, validating and analyzing athletic movement data. Generally, a sensor device, such as a force plate, is provided for sensing certain characteristics of an athletic movement. A local computing device coupled to the sensor device can be configured to receive sensor data indicative of the characteristics of the athletic movement, process and extract information from the sensor data, and transmit the processed sensor data to a remote server system. The remote server system can be configured to store, aggregate and update the processed sensor data in a database, and can also generate one or more normalized scores correlating to the athletic movement. The normalized scores can indicate to a user a susceptibility to injury, progression towards return to play or propensity for success with respect to a particular sport.

An electronic device and a method for providing information thereof are provided. In an embodiment, the electronic device is configured to receive a user input for selecting an exercise through a user interface or a wireless communication circuit, select a guide image corresponding to the selected exercise, analyze the selected guide image, acquire a first image of a user through at least one camera at a first location, determine a second location for the electronic device based at least in part on the analyzed guide image and the acquired first image of the user, control at least one driver to move the electronic device based at least in part on the determined second location, acquire a second image of the user through the at least one camera after a movement of the electronic device, and generate a combined image by combining the selected guide image and the acquired second image of the user.

The invention is directed to improve the body alignment in the water of a swimmer. The head band sits on the back of the head allowing the rod to extend down the back to between the shoulder blades. This limits two motions that are undesirable for efficient swimming of the crawl stroke: inappropriate lifting of the head from the neck and over rotating the neck. This lowered neck position and limited neck rotation forces the swimmer to rotate more from the torso in order to clear the water with their mouth and breath and keep the swimmer in an improved body position.

A headset including a speaker, a motion sensor, a transceiver, and a processor is provided. The speaker plays audio data. The motion sensor senses a posture of a user to generate first sensing data. The transceiver performs data transmission with an external device. The processor is coupled to the motion sensor and the transceiver. The processor determines whether the posture is correct according to the first sensing data to generate an output result and transmits the output result through the transceiver.

A cycling-posture analyzing system and method are provided. The cycling-posture analyzing system includes a plurality of motion sensors, a pressure sensor and an electronic device. The plurality of motion sensors are disposed on a human body and are configured to detect a plurality of pieces of motion information. The pressure sensor is disposed at a plantar aspect of the human body and is configured to detect pressure information. The electronic device is configured to receive the plurality of pieces of motion information from the plurality of motion sensors, receive the pressure information from the pressure sensor, and use the plurality of pieces of motion information and the pressure information to determine cycling-posture type information according to a cycling-posture identification model.

Provided is a personal fitness machine device using VR including: a driving unit collecting front location information of a user and front posture information of the user; a VR unit which collects rear location information, rear posture information, and distance information of the user; an exercise unit including a bottom frame, a footrest unit, a separation prevention unit, a back support frame, and a waist protector, and a control unit which controls the driving unit, the VR unit, and the exercise unit, compares the front posture information of the user and pre-stored posture information, and generates posture correction information.

A video reproduction apparatus determines a position of a joint of a performer based on a sensing result by a sensor. The video reproduction apparatus calculates an angle formed by a joint used for scoring an element of an athletic event by using calculation information regarding a calculation formula for calculating the angle and the determined position of the joint of the performer. The video reproduction apparatus displays a performance image of the performer acquired from a camera and a scoring image having the angle displayed on a 3D model image of the performer which is generated according to the sensing result so as to be compared with each other.

A method for motion data processing includes: sensing a plurality of motion data of football player by a magnetic football and magnetic sensors; according to the motion data, analyzing the player's motion trajectory by a processing chip, and identifying whether the player's kicking motion is sliding tackle, smashing or dribbling.
