Abstract: A method for configuring a virtual sensor in a real scene, the method comprising: obtaining at least one first three dimensional (3D) representation of the real scene, analyzing said at least one first 3D representation to detect a beacon in the real scene and computing from said at least one first 3D representation a position of the beacon in the real scene; generating virtual sensor configuration data for the virtual sensor on the basis at least of the position of the beacon, the virtual sensor configuration data representing a volume area having a predefined positioning with respect to the beacon, at least one virtual sensor trigger condition associated with the volume area, and at least one operation to be triggered when said at least one virtual sensor trigger condition is fulfilled.

Abstract: Systems and methods for controlling a virtual interactive surface in a scene include a surface for displaying information and one or several virtual sensors positioned with respect to the surface. The virtual sensor includes data representing a geometric form, data representing a position in the scene, and data representing one or several trigger conditions. A data representation of the scene is captured and a determination whether a virtual sensor trigger condition is fulfilled is made, based on an analysis of the captured data representation in an area corresponding to the geometric form and position of the virtual sensor.

Abstract: Methods and systems for detecting activation of a virtual sensor in a scene are proposed, wherein the virtual sensor comprises data representing a geometric form, data representing a position in the scene and data representing one or several trigger conditions. A data representation of the scene is captured, and a determination of whether a virtual sensor trigger condition is fulfilled is made, based on an analysis of the captured data representation in an area corresponding to the geometric form and position of the virtual sensor.

Abstract: According to one aspect, the invention relates to a system for determining the movements of an object from a stream of images of said object. The system includes, in particular, a computer having a memory and a central processing unit, said central processing unit including: a reading unit (12) for recording each image of the stream of images in an input buffer memory (22); a processing unit (13) making it possible to determine, for each image, a change in the position and/or in the deformation of said object relative to the image immediately preceding said image in the stream; the reading and processing units being synchronized such that the processing of each of said images of the stream of images is carried out either simultaneously at the time of the reading of an image following said image in the stream of images, and of the recording thereof in the input buffer memory (22).
