In this paper, a psychophysical investigation to improve a visibility of a transparent display is presented. A new illuminance measurement method for the transparent display, named eye illuminance, is proposed. Through a psychophysical experiment, it is found that the eye illuminance is strongly related with the visibility of the transparent display regardless of its background condition. This paper finds out the optimum emission luminance range of the transparent display under various illuminant conditions. Also, the contrast ratio for visibility is analyzed and it is found that a higher contrast ratio is not needed to provide a visually better image under a brighter ambient environment. In conclusion, our findings will contribute to an auto brightness control technology to improve the visibility of the transparent display for augmented reality devices.

研究如何在各种环境条件下提高透明显示器对增强现实的可见性。

在本文中，提出了一种心理物理研究来提高透明显示器的可见性。提出了一种新的透明显示器照度测量方法，称为眼睛照度。通过心理物理实验发现，无论背景条件如何，眼睛的照度都与透明显示器的可见度密切相关。找出了在各种光源条件下透明显示器的最佳发光亮度范围。而且，分析了用于可见性的对比度，并且发现在更高的周围环境下不需要更高的对比度来提供视觉上更好的图像。结论，
