Abstract
The present invention relates to a system and method of analyzing the movement of a user. More particularly the present invention relates to a new technique for assessing a user's motor functions. It is an object of the present invention to provide a simple, robust, and low-cost technique for analyzing the movement of a user, which can be used in an unsupervised home environment. This object is achieved according to the invention by a method of analyzing the movement of a user, the method comprising the steps of causing the user to perform a coordinated movement in accordance with an instruction, generating video image data in form of a sequence of images by video recording the user, determining in the sequence of images a degree of synchronicity of optical flow on the left and right body half using a computer system comprising computer vision technology, and assessing the user's motor functions based on the degree of synchronicity.
