Evaluation of Colorimetric Characteristics of Head-Mounted Displays

In order to determine if four HMD offer characteristics that are sufficient for applications that require precise control of colors displayed, we use a method inspired by two tests extensively used for screening of deficiencies in color vision: the Farnsworth Munsell D-15 and the Lanthony test, which are both based on the arrangement of fifteen color caps so as to reduce the color difference between two neighboring caps. After performing colorimetric characterization of the HMD, patches that match for the Farnsworth and Lanthony cap colors are created, and the color differences between two patches are measured in the CIE Lab space. We find out that, for some of the devices, differences in color may become very slight, and reach the perception threshold. It is deduced that these devices would fail to display the color characteristics of an image with a sufficient level of accuracy.
