Claim One:
1. A method of tracking a shape in a scene, comprising: receiving asynchronous information from a light sensor having a matrix of pixels arranged opposite the scene, wherein the asynchronous information comprises, for each pixel of the matrix, successive events originating asynchronously from said pixel; and updating a model comprising a set of points and representing a tracked shape of an object, after detecting events attributed to said object in the asynchronous information, wherein the updating comprises, following detection of an event: associating with the detected event a point of the model having a minimum distance with respect to the pixel of the matrix from which the detected event originates; and generating the updated model according to the pixel of the matrix from which the detected event originates and the associated point, and independently of associations made between points of the model and detected events before the detection of said event.
