新一代(第四代)人机交互的概念框架特征及关键技术

人机交互是研究人与计算机之间通过相互理解的交流与通信,在最大程度上为人们完成信息管理,服务和处理等功能的一门技术科学.本文给出新一代(第四代)人机交互的概念框架和其四个标志性特征,即:(1)具有多模感知(听觉,视觉,手势,笔势等)功能的人机交互方式;(2)可进行基于Agent的听、视觉对话,作为人机交互的界面;(3)具有Internet数据仓库和基于内容检索的知识处理能力,作为人机交互内容;(4)可以在二维或虚拟的三维环境中实现人机通信,作为人机交互的环境.文中给出了解决和实现该四大特征的关键技术,描述了实验系统平台的全面功能,可以为同类研究人员作参考.

A Conceptual Model and Features of New Generation (Fourth Generation) Human-Computer Interactive Systems

Human-computer interaction is a complex of technical science,which investigates the interaction and communications through mutual understanding between human and computers to solve problems of information managements,services and processing in maximized degree for human needs.This paper proposed a conceptual model of new generation (fourth generation) human-computer interaction systems and their four major features:(1) the ways for interaction are through multimodel perceptions (hearing,vision, gestures and pen writing); (2) the interface for interaction is through the intellegent agents,who may understand user's requirements and implement all required processing by machine through auditory/visual diologues; (3) the contents for interaction may be performed by techniques of content based text or image/video retrieval; (4) the display environment of interaction may be realized in 2-D or 3D through virtual browsing the 3-D scene of computer graphics reconstructed by 3-D computer vision technique.In this paper the possible solutions and algorithms to implement these four major features are given and the platform of the 4th human computer interative system is also described.
