SCREEN WITH MAGNETIC OBJECT LOCATING

摘要

This screen comprises: a locating device (12) for locating a mobile permanent magnet that can be moved directly by hand by a human being in front of a tile (102), said device comprising: a network of magnetometers comprising N triaxial magnetometers (Mij) mechanically linked to each other without any degree of freedom in order to retain a known distance between each of said magnetometers, where N is a whole number greater than or equal to five, an electronic processing unit capable of determining the position and/or orientation of the permanent magnet from measurements of the magnetometers of said network, and a unit (112) capable of controlling a photon generating layer (106) to modify the display on the basis of the position and/or orientation determined by the locating device.
