摘要

VideoWriter是对将自然用户界面应用于电传书写的一项研究。它使用一台电脑控制的摄像机来捕捉用户书写空间的图像:一张放着各种纸张的桌子。对图像进行处理，从场景中杂乱的物体(包括用户移动的手和笔)中提取当前页面上的书写标记。系统对提取的信号进行压缩传输。该系统成功地提取了用户书写时的标记，并避免了大多数虚假标记的数字化。它包含了处理确实发生的错误标记的更新机制。

The VideoWriter: towards active paper for a natural user interface

The VideoWriter is an investigation into applying a natural user interface to telewriting. It employs a computer-controlled video camera to capture images of the user's writing space: a desk with various pieces of paper. The images are processed to extract the written marks on the current page from the clutter of objects in the scene, including the user's moving hand and pen. The system compresses the extracted marks for transmission. The system is successful at extracting the marks as the user is writing and avoids digitizing most false marks. It incorporates update mechanisms that deal with false marks that do occur.
