VR-test ViKi: VR Test with Visual and Kinesthetic Stimulation for Assessment Color Vision Deficiencies in Adults

Abstract:

Visual color perception in humans is produced in the sensitive cells of the retina, which are called cones. There are three types of cones: those that capture red, green, and blue light. The deficiency of color perception implies that the person sees different colors from other people, and “confuses” or interchanges some of them, or that sees directly in black and white. Some professions such as pilots, surgeons, electricians, dentists, designers, among others, require an accurate perception of color to be able to safely perform their functions. There are several traditional test for diagnosing color vision deficiencies and applications using conventional devices. In this work, we propose a new approach to assess the color vision deficiencies using VR devices. We are developing a visual color test (VR-test ViKi) based on the Ishihara test including visual and kinaesthetic stimulation. It includes a virtual environment, ten 3D objects, a predetermined short path, a bridge, four circular figures with numbers, 3D objects, a hummer modeled on the inside and outside, and a virtual task. Also, the virtual environment shows three conditions: sunny, rainy, and night. Two types of HMDs will be used. Assessment methods will include two questionnaires (SSQ and PQ), the Ishihara test, remember the numbers seen, and time task. Also, we will compare the performance between the Ishihara test and VR-test ViKi. This research will contribute to improve the visual evaluation process in access to aviation schools. We will contribute with a complementary tool to assess color vision deficiency.
