Abstract: A method for analysing one of a rehabilitation activity and a performance of a user during a rehabilitation exercise, comprising: receiving one of a rehabilitation activity and executed movements performed by the user during the rehabilitation exercise, the rehabilitation activity defining an interactive environment to be used for generating a simulation that corresponds to the rehabilitation exercise; determining movement rules corresponding to the one of the rehabilitation activity and the rehabilitation exercise; determining a sequence of movement events corresponding to the one of the rehabilitation activity and the rehabilitation exercise, each one of the movement events corresponding to a given state of the property of the virtual user-controlled object in the interactive environment, the given state corresponding to one of a beginning and an end of a movement; and determining a movement sequence of elementary movements using the movement rules and the movement events.

Abstract: A method for evaluating a user during a virtual-reality rehabilitation exercise, comprising: receiving a target sequence of movements comprising at least a first target elementary movement and a second target elementary movement; receiving a measurement of a movement executed by the user while performing the rehabilitation exercise and interacting with a virtual-reality simulation comprising at least a virtual user-controlled object, a characteristic of the virtual user-controlled object being controlled by the movement; determining, from the measurement of the movement executed by the user, a sequence of measured movements comprising at least a first measured elementary movement and a second measured elementary movement; comparing the sequence of measured movements to the sequence of target movements; and outputting an evaluation.
