下一代显示技术需要自然的3D显示。我们已经证明，当大量定向图像（3D场景的正交投影）以非常小的角度投影到相应的方向时，会引起调节反应。我们还构建了一个三维显示器，将64幅定向图像显示在不同的水平方向上，水平角俯仰为0.34°。使用高密度的定向图像，而不是视差图像（3D场景的透视投影），除了适应唤起外，还可以获得非常平滑的运动视差。在本研究中，我们开发了一种新的三维显示器，用于调查日本总务省委托的自然三维显示条件。采用128个小液晶面板，可同时显示128个方向图像。水平视角为29.6°，水平显示角度间距为0.23°。屏幕尺寸为13.2英寸。3D显示器由16台PC组成的PC集群控制。我们还在开发能够测量双眼调节、辐角和瞳孔直径动态响应的设备。该设备将用于研究最佳的3D显示条件。
A natural 3D display is required for the next-generation display techniques. We have already demonstrated that the accommodation responses are evoked when a large number of directional images, which are orthographic projections of 3D scenes, are projected into the corresponding directions with a very small angle pitch. We have also constructed a three-dimensional display which displayed 64 directional images into different horizontal directions with the horizontal angle pitch of 0.34°. With high-density directional images, not parallax images (perspective projection of 3D scenes), very smooth motion parallax is obtained in addition to the accommodation evocation. In this study we develop a new 3D display which is used to investigate the natural 3D displaying conditions on commission of the Japanese ministry of internal affairs and communications. It can display 128 directional images simultaneously by using 128 small LCD panels. The horizontal viewing angle is 29.6° and the horizontal display angle pitch is 0.23°. The screen size is 13.2 inches. The 3D display is controlled by a PC cluster consisted of 16 PC’s. We are also developing equipment which can measure the dynamic responses of the accommodation, the vergence, and the pupil diameters of both eyes. This equipment will be used to investigate the optimum 3D display conditions.
