Along with rapid development of human computer interaction system , emotion in speech is a topic that has received much attention during the last few years , in the context of speech synthesis as well as in automatic speech recognition 随着人机交互系统的快速发展,语音信号中的情感信息近年来正越来越受到人们的重视,特别是在语音合成和语音识别等领域。
In desktop computing environment , the style of human computer interaction has been changed from command user interface to multimedia graphical user interface which is a temporary alternative of natural human computer interaction mode 在桌面计算系统中人机接口已从早期的命令字符方式发展到现代的多媒体图形用户交互形式，并成为自然人机交互技术实现之前的一种过渡方式。
In recent years , it shows important application value in many fields include that visual supervise , content - based video retrieval and new human computer interaction and so on . so many people are taking it seriously as an independent problem 近年来，由于其在安全访问控制、视觉监测、基于内容的检索和新一代人机界面等领域的应用价值，开始作为一个独立的课题受到研究者的普遍重视。
The methods of graphics recognition in intelligent human computer interaction are studied thoroughly in this dissertation . some new pattern recognition techniques in recent years are used in my study , and get improved in my application background 本文对智能人机交互中的图形识别方法进行了深入系统地研究，在研究中，应用了近年来模式识别中分类器联合方面以及图像匹配方面的一些新方法，并且结合应用背景对这些方法进行了进一步的改进。
After expounding vr concept and its characters , the necessity and rationality of vr existence and its application in cad / cam , several other aspects are studied : first , the three kinds of stereoscopic display theory are set forth and the research is focused on the theory which is based on parallax and discussed from the aspects such as the physical basis of the third dimension production , the influencing factors of third dimension , the theory and arithmetic of drawing stereoscopic figures etc ; second , the difference among vr , other interaction methods and vr ' s status are studied from the perspective of human computer interaction development , the cognitive psychology model of vr interaction is analyzed and a classification study on vr is done according to different operation missions and metaphors ; third , the concept of virtual design is given out based on the research on its other concepts , then the difference among vr , cad and the realization of virtual design are studied 在阐述虚拟现实的基本概念与特性、存在的必要性与合理性,以及在cad / cam方面的应用的基础上,本文深入研究了: 1 .虚拟现实的三种立体显示原理,着重于基于视差方式的立体显示,从以下几个方面进行了多角度的探讨:产生立体感的生理基础,立体感影响因素,立体图绘制原理与算法等。 2 .虚拟现实的交互原理,从人机交互的发展角度研究了虚拟现实与其它交互方式的异同以及它所处的地位,分析了虚拟现实交互的认知心理学模型,并按作用于对象的任务不同和交互隐喻方式的不同对虚拟现实的交互方式进行了分类研究。 3 .虚拟设计,在研究虚拟设计的各种定义方式的基础上定义了本文中虚拟设计的概念,研究了它相对于传统cad的不同之处,以及虚拟设计的实现规划。
Images containing faces are essential to intelligent vision - based human computer interaction , and research efforts in face processing include face recognition , face tracking , pose estimation , and expression recognition . however , all of these researching directions involve in one problem - face detection and location , in other words , before this face processing , we must know faces " locations and scales 在目前的人脸图象信息处理领域中，包含有人脸识别、人脸跟踪、姿态估计、表情识别等多个研究方向，然而，所有这些研究方向都涉及到一个人脸标识和定位的问题，即必须知道人脸在图象中的位置以及尺寸? ?人脸检测。
Centered around graphics recognition in intelligent human computer interaction , stroke recognition of online graphics using single classifier , stroke recognition of online graphics using multi classifier combination , structure recognition of online graphics , offline graphics recognition and icon semantics association are discussed respectively in the dissertation 本文围绕智能人机交互中的图形识别这个主题，分别讨论了联机图形笔划的单分类器识别、联机图形笔划的多分类器联合识别、联机图形的结构识别、脱机图形符号识别和图形符号语义联想等内容。
Clustering result visualization . information visualization is the precondition for human computer interaction to data mining . because of the data sets extend , it is a hotpot that how to express the high dimensionality data in 2 - dimensionality space , and provide a compact and effective visualization interface for the user 信息可视化是当前人机交互进行数据挖掘的前提，由于数据集合规模的不断扩大，如何将高维数据通过二维空间表示出来，并简洁的、有效的为用户提供一个数据的可视化界面成为研究热点。
