Daltonization by spectral filtering

Abstract

Color deficiency tests are well known all over the world. However, there are not applications that attempt to simulate these tests with total color accuracy in virtual reality using spectral color computing. In this work a study has been made of the tools that exist in the market in VR environments to simulate the experience of users suffering from color vision deficiencies (CVD) and the VR tools that detect CVD. A description of these tools is provided and a new proposal is presented, developed using Unity Game Engine software and HTC Vive VR glasses as Head Mounted Display (HMD). The objective of this work is to assess the ability of normal and defective observers to discriminate color by means of a color arrangement test in a virtual reality environment. The virtual environment that has been generated allows observers to perform a virtual version of the Farnsworth-Munsell 100 Hue (FM 100) color arrangement test. In order to test the effectiveness of the virtual reality test, experiments have been carried out with real users, the results of which we will see in this paper.
