Life-like Agent Interface System on a User-tracking Active Display

我们开发了一个具有纹理映射的逼真3D面部的逼真代理界面系统，称为VSA-II （Visual Software agent - ii）。由于真实的3D人脸是由一张照片生成的，所以很容易添加一些代理角色，而不需要任何特殊的艺术技巧。一个活生生的背景形象提高了拟人化代理人角色的生活感。代理可以控制ie浏览器呈现任何文本和视觉信息，同时代理通过合成语音与用户对话。它通过一个用户跟踪主动显示器与用户协同交互，这是一个电机驱动的TFT显示器，它会自动将屏幕转向用户的脸。显示器屏幕可以随着用户的移动摆动300度以上的角位移，然后代理角色可以与在屏幕周围走动的用户保持目光接触。它可以将用户从电脑前的座位上解放出来，这为人机交互开辟了新的可能性。它还可以作为选择性交互的测试平台系统；也就是说，与在屏幕上走动的其他用户之间的指定用户的交互。

We have developed a life-like agent interface system with a texture-mapped realistic 3D face, called the VSA-II (Visual Software Agent-II). Since the realistic 3D face is generated from a single photograph, it is easy to add some agent characters without any special artistic skill. A live background image raises the life-likeness of the anthropomorphic agent character. The agent can control the Internet Explorer to present any text and visual information, while the agent talks with users by synthetic voice. It interacts with users cooperatively by means of a user-tracking active display, which is a motor drive TFT monitor that automatically turns the screen to the user's face. The monitor screen can swing more than 300 degrees angular displacement along the user's movement, then the agent character can keep eye contact with a user walking around the screen. It can release the user from a seat in front of a computer, which opens new possibilities for human-computer interaction. It also works as a test-bed system for selective interaction ; that is, the interaction with the specified user among other users walking around the screen.
