INTRODUCTION: The importance of possessing the proper skills "to see the course" ("Toni" Sailer) is well known. In this study, an attempt to evaluate visual 3D perception different factors to the results of the virtual skiing is presented. METHOD: For experiments using next-generation of visual-force training complex, described in [1] and its improved version [2]. We study the following factors: 1. Traditional 3D stereo vision based on the binocular parallax 2. Effects of visibility - fog, light absorption, snow, spectral filters 3. Vision accommodation To solve the problems of synchronization and augmentation of physical adequacy and realism of 3D scene rendering is used the real alpine skiing video. RESULTS: In the experiments, the contribution of the above factors on the virtual ski descent time is estimated. A large part of the vision accommodation in the right perception of the 3D course is revealed. DISCUSSION: Effect of 3D stereo vision based on binocular parallax is comparable to the role of accommodation. To study the effect of accommodation proposed simulator device of the turning pole visualization. This device reproduces the change of the wave front, on the basis of spherical flexible mirror or liquid crystal adaptive lenses. CONCLUSION: Designed visual-force training complex allows the study of 3D perception of ski course in the laboratory. It would be interesting to examine more closely the impact of vision accommodation on the skiing (e.g., the role of myopia and hyperopia).
