Wall Display with Simultaneous Presentation for Individuals and Crowd

本研究的目的是在一个大规模的墙壁显示器上同时显示个人和人群的内容。大型墙壁显示器不仅用于公共广告，而且还为个人提供个人内容。然而，在传统的显示系统中，公共内容和个人内容是彼此排他的，因为个人内容在用于提供内容的同时占据显示器。所提出的方法使用距离图像传感器和相机来估计在显示器前面的每个用户的位置和方向。用户被分为操作者、观看者和传递者。从用户的位置估计来自观看者的不可见区域，并且操作者的个人内容被操作者的身体隐藏。实验结果表明，该方法可以同时显示公共和个人内容。

This research is aiming at showing contents for both an individual and crowd on a large-scale wall display simultaneously. A large-scale wall display is not only used for public advertisement but also providing a personal content for an individual. However, the public and the personal contents have been exclusive each other in conventional display systems, because the personal content occupies the display while it is used for serving the content. The proposed method uses a range image sensor and a camera for estimating a position and a direction of each user who is in front of the display. The user is classified into an operator, a viewer and a passer. Invisible regions from the viewers are estimated from the position of the users, and the personal content for the operator is hidden by the body of the operator. Experimental results have been demonstrated that the proposed method can display the public and the personal contents simultaneously.
