摘要

我们提出了一种新的显示技术,以不同的可见性向多个用户呈现信息。该系统通过投影仪前面的旋转线性偏光镜将信息投射到屏幕上,并通过用户视点前面的另一个偏光镜显示信息。观测到的信息的亮度根据两个偏振器之间的偏振轴的相对角度降低,从而允许应用程序通过控制旋转偏振器的角度为每个用户提供不同任意亮度水平的信息。通过对实现样机的亮度值进行测量,验证了该方法的有效性。然后,我们描述了几个示例应用程序,展示了该技术的优点:为特定用户隐藏和分类信息。此外,我们还描述了一个娱乐应用程序和展示的有形偏光器的示例。

Visibility control using revolving polarizer
We propose a novel display technique that presents information with different visibility to multiple users. The system projects information on a screen through a revolving linear polarizer in front of the projector, and it shows information through another polarizer in front of the userpsilas viewpoint. The brightness of the observed information is reduced according to the relative angle of the polarization axes between the two polarizers, thereby allowing applications to provide information at different arbitrary levels of brightness for each user by controlling the angle of the revolving polarizer. By measuring the brightness values of an implemented prototype, we demonstrate that the proposed method is effective. We then describe several example applications showing the benefit of the technique: concealment and classification of information for specific users. In addition, we describe an example of an entertainment application and a tangible polarizer on display.
