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: The present invention relates to the preparation of ?-substituted ?-amino carboxylic acids, preferably in enantiomerically enriched or even enantiomerically pure form, by a one-pot conversion of a ?-substituted ?-nitro dicarboxylic acid ester or of a ?-substituted ?-nitro dicarboxylate of general formula to a ?-substituted ?-nitro carboxylic acid and a subsequent reduction of the ?-nitro group to an amine group. In particular, the present invention relates to the preparation of (S)-pregabalin. In addition, the formation of enantiomerically enriched ?-substituted ?-amino carboxylic acids and ?-substituted ?-nitronate carboxylic acid salts are also described.
