Abstract
A method for displaying an image onto a relief projection surface using a projection system includes the automatic measurement, using a fixed camera, of the distance separating virtual reference frame points projected onto the projection surface, from real reference frame points produced on a three-dimensional screen to set the projection system, acquisition, by the same fixed camera as that used during the setting of the projection system, of an image of a rear face of the three-dimensional screen, identification of the position of a finger in contact with a front face of the three-dimensional screen in the acquired image, and control of an appliance according to the identified position of the finger.
