Abstract

The multi-surface interactive display projector (MSIDP) is a steerable projection system that transforms non-tethered surfaces into interactive displays. In an MSIDP, the display image is directed onto a surface by a rotating mirror. Oblique projection distortions are removed by a computer-graphics reverse-distortion process and user interaction (pointing and clicking) is achieved by detecting hand movements with a video camera. The MSIDP is a generic input/output device to be used in applications that require computer access from different locations of a space or computer action in the real world (such as locating objects). In particular, it can also be used to provide computer access in public spaces and to people with locomotive disabilities.
使用可操纵的投影仪和摄像机将表面转换为交互式显示器
多表面交互显示投影仪(MSIDP)是一种可操纵的投影系统,它将非系绳表面转换为交互式显示。在MSIDP中,显示图像通过旋转镜定向到表面上。斜投影失真通过计算机图形反向失真处理去除,用户交互(指向和点击)通过视频摄像机检测手部运动来实现。MSIDP是一种通用的输入/输出设备,用于需要从空间的不同位置进行计算机访问或在现实世界中进行计算机操作(例如定位对象)的应用程序。特别是,它还可以用于在公共场所和残疾人士提供电脑访问。
