A sports and performance media positional detection system, comprising: at least two elements, with at least one element involved in the sporting activity; a power source; and machine-to-machine communication, which are collectively arranged such that if any two or more elements interact, their electromagnetic properties can be detected thus allowing the position of the interacting elements to be communicated to a decision maker. The system can be applied to at least one stationary element, which can be the playing surface, lines defining the boundaries, or a set of goalposts; and at least one moving element, which could be a ball, footwear, or the participants themselves. The system can also be applied to performance media capture.

Systems, methods, and other embodiments associated with instruction production are described. In one example, a system can comprise a difference component that makes an identification of a difference between an actual action of a user and a standard action for the user. The system also can comprise an instruction component that produces an instruction to instruct the user to change from the action of the user to the standard action for the user, where production of the instruction is based, at least in part, on the difference. The system further can comprise a non-transitory computer-readable medium configured to retain the instruction. Additionally, the system can comprise an output component configured to cause disclosure of the instruction.

Provided is a method for evaluating pose in standing long jump, an electronic device, and a storage medium, relating to the field of computer vision applicable to scenarios of physical education, fitness testing, and training for adolescents. The method includes: generating, for a video frame in a standing long jump video of a target object, a body spatial position, a joint angle, a relative position parameter of a body part and a body moving velocity of the target object in the video frame; extracting key motion frames from the standing long jump video; obtaining a key motion evaluation result of the target object in a key motion frame; and determining a standing long jump pose evaluation result according to the key motion evaluation result of the target object.
