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.
