本文提出了一种新的桌面显示命名为“桌面”，可以发射不可感知的元数据沿着的桌面图像。实际上，我们的系统在桌面上显示一个视觉图像，其像素包含元数据作为专用接收器的位模式。由于位模式被嵌入为高速闪烁，用户不会察觉到隐藏在图像后面的信号。然而，我们可以通过在桌面上放置独立的接收器来读取元数据。由于隐藏信号独立地嵌入在每个像素中，因此可以根据桌面上的位置绘制不同的元数据。我们的系统的优点是，它可以隐藏的元数据，这是强烈相关的图像内容在一个不可感知的方式。本文介绍了详细的设计和几个应用。
This paper proposes a novel tabletop display named "EmiTable" that can emit imperceptible metadata along with the tabletop image. Actually, our system displays a visual image on the tabletop whose pixels contain metadata as bit patterns for dedicated receivers. Since the bit patterns are embedded as high-speed flickers, the users would not perceive the hidden signal behind the image. However, we can read out the metadata by putting stand-alone receivers on the tabletop. Since the hidden signal is embedded independently in each pixel, different metadata can be drawn according to the position on the tabletop. The advantage of our system is that it can superimpose metadata which are strongly related to the image content in an imperceptible way. This paper presents the detailed design and several applications.
