Abstract: A method which includes obtaining a first sequence of images of a user attempting to reproduce a sequence of poses of a reference user and determining correct performance of the user. For each body part of a plurality of body parts of the user, a spatial orientation of the body part in a referential independent of an orientation of any other body part of the user is compared to the spatial orientation of the reference user. If the comparison does not meet a matching criterion for at least one body part of the user, data representative of a mismatch between the orientation of the body part of the user and the spatial orientation of the reference user is output, thereby enabling the user to correct his pose using a feedback pointing to the body part to be corrected.

Abstract: A method which comprises, by a processor and memory circuitry: obtaining a first sequence of images of a user, determining correct performance of a pose of the user in the first sequence of images, including based on at least one image, for each body part of a plurality of body parts of the user, comparing at least one of spatial orientation and position of the body part, or of at least one body node thereof, with at least one of desired spatial orientation and position, if the comparison does not meet a matching criterion for at least one body part of the user, or of at least one body node thereof, outputting data representative of a mismatch between the at least one body part of the user, or of the at least one body node thereof, and the at least one of desired spatial orientation and position.
