This paper introduces a method for visualizing electromagnetic field distribution using marker-less AR (augmented reality). Visualization of the electromagnetic field is important for understanding its spatial distribution because the field is invisible. In our previous studies, to display the electromagnetic field distribution in three dimensions, multiple 2D distributions were aligned side by side or displaying contour lines were used. In recent years, an AR technology have rapidly spread, and methods for displaying the distribution of electromagnetic fields on a circuit board and around a fluorescent light in three-dimensions have been reported. AR technology usually requires an AR marker which has geometric pattern on it. However, by using the feature points in a monitoring area as a marker, it is possible to display AR objects without special markers. In this study, we introduce a visualizing method which uses the magnetic field meter as an AR marker and visualize a field distribution on a multiple terminal simultaneously. This measurement method is effective not only for exposure assessment purposes, but also as a material for learning electromagnetic field distribution.
