SCREEN WITH MAGNETIC OBJECT LOCATING

摘要

A screen comprising a transparent panel and a photon-generating layer in order to form each luminous pixel visible through the transparent panel, this layer being housed behind the transparent panel. There is a human/machine interface able to control the photon-generating layer in order to modify the display of an image by the screen. The interface includes a localizing device for localizing a movable permanent magnet able to be moved directly by hand by a human being in front of the panel, this device comprising for this purpose. The interface also includes a network of magnetometers comprising N tri-axis magnetometers mechanically connected to one another with no degree of freedom in order to maintain a known distance between each of these magnetometers, where N is a whole number higher than or equal to five. There is an electronic processing unit able to determine the position and/or orientation of the permanent magnet from the measurements of the magnetometers of this network and a unit able to control the photon-generating layer in order to modify the display depending on the position and/or orientation determined by the device for localizing.
