移动计算的最新进展使用户可以在手持计算机上处理3D交互式图形。尽管计算资源和屏幕分辨率稳步增长，但手持计算机的用户界面并没有发生显着变化。因此，我们设计了一个适合手持计算机特性的新的3-DOF接口。该接口通过分析手持计算机相机的视频流来跟踪用户在屏幕后面保留的目标的运动。目标的位置是通过使用有效算法在其上打印的颜色代码直接推断出的。用户可以在移动设置中轻松实时互动。数据的可视化是良好的，因为目标没有阻塞屏幕，并且交互技术不取决于手持计算机的方向。我们在多个测试应用程序中使用了接口来可视化大图像，例如地图，3D模型的操纵以及3D场景中的导航。这个新的接口有利于手持计算机上2D和3D交互式应用程序的开发。
Recent advances in mobile computing allow the users to deal with 3D interactive graphics on handheld computers. Although the computing resources and screen resolutions grow steadily, user interfaces for handheld computers do not change significantly. Consequently, we designed a new 3-DOF interface adapted to the characteristics of handheld computers. This interface tracks the movement of a target that the user holds behind the screen by analyzing the video stream of the handheld computer camera. The position of the target is directly inferred from the color-codes that are printed on it using an efficient algorithm. The users can easily interact in real-time in a mobile setting. The visualization of the data is good as the target does not occlude the screen and the interaction techniques are not dependent on the orientation of the handheld computer. We used the interface in several test applications for the visualization of large images such as maps, the manipulation of 3D models, and the navigation in 3D scenes. This new interface favors the development of 2D and 3D interactive applications on handheld computers.
