Claim One:
1. A method for controlling a virtual interactive surface in a scene, wherein the virtual interactive surface comprises a surface for displaying information and one or several virtual sensors positioned with respect to the surface, wherein a virtual sensor comprises data representing a geometric form, data representing a position in the scene and data representing one or several trigger conditions, the method comprising: capturing a first data representation of the scene; generating point cloud data representing surfaces of objects of the captured scene, the point cloud data comprising data representing non-empty points of a first volume area corresponding to the captured first data representation and respective associated position in the first volume area; and determining whether one or several of the virtual sensor trigger conditions is/are fulfilled based on an analysis of the captured first data representation in a volume area corresponding to the geometric form and position of each virtual sensor, wherein for a first virtual sensor said analysis comprises comparing a number of non-empty points whose position falls in the volume area corresponding to the geometric form and position of said first virtual sensor is greater to a triggering threshold.
