These screens have different sizes, shapes, and mutual disposition depending on the form factor of the device. The projections of virtual objects are formed so that the virtual image the user sees looks exactly the same as the image that would see if the virtual object actually existed. In order to display the correct projections of virtual objects, the virtual reality system requires the current coordinates of the observer, namely, the coordinates of the user's eyes.〔 In contrast with stereo displays involving only binocular vision, the MotionParallax3D displays utilize one of the most important principles of human spatial perception—motion parallax. Motion parallax is a displacement of the parts of the image relative to each other with the angular velocity proportional to the distance difference between the parts of the image and a viewer when the relative position of the viewer and the observed object changes.〔〔 The MotionParallax3D displays use this mechanism of perceiving volume by constantly changing the image displayed based on the current coordinates of the user's eyes. Due to this, the virtual objects are shifted relative to each other and relative to the visible real objects according to the laws and principles applying to the real world’s objects. It allows the brain to build the a holistic view of the world containing both real and virtual objects with indistinguishable behavior. Most MotionParallax3D displays are based on stereo displays and display separate images to the left and right eyes. This gives a substantial advantage in building a complete system of virtual reality, but is not necessary for the perception of volume since the motion parallax mechanism alone is enough for the brain to perceive virtual objects as having a definite shape, volume, and a distance from the user’s eyes.〔〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MotionParallax3D」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
