论文摘要
已经大量精力致力于从图像序列中自动提取有关面部作用的信息。在人类计算机相互作用（HCI）的背景下，我们可以区分允许表达旨在识别的系统。面部动作处理中的大多数工作都是针对自动识别面部动作影响的。相比之下，对故意面部动作做出反应的面部手势界面受到了相对较少的关注。本文回顾了几个基于视觉界面的项目，这些项目依赖于有意的HCI面部动作。引入了几个领域的应用程序，包括针对运动障碍用户的文本输入，艺术和音乐表达以及辅助技术。
Considerable effort has been devoted to the automatic extraction of information about action of the face from image sequences. Within the context of human-computer interaction (HCI) we may distinguish systems that allow expression from those which aim at recognition. Most of the work in facial action processing has been directed at automatically recognizing affect from facial actions. By contrast, facial gesture interfaces, which respond to deliberate facial actions, have received comparatively little attention. This paper reviews several projects on vision-based interfaces that rely on facial action for intentional HCI. Applications to several domains are introduced, including text entry, artistic and musical expression and assistive technology for motor-impaired users.
