基于Silverlight互动学习RIA平台的研究与实现

为了解决目前Web学习平台的表现力不足和互动性差等问题,本文在分析RIA基本工作原理的基础上,结合RIA客户端具备丰富的媒体元素描述能力的技术特点,提出了互动学习RIA平台总体框架和体系结构。利用Silver-light技术,在Web环境中实现了手写技术,并结合WCF技术,解决了Web环境中手写识别问题;利用RIA在客户端实现呈现逻辑控制的特点,实现了对象拖动与碰撞检测等功能,并运用到互动学习RIA平台的系统设计中。手写、手写识别等技术不但丰富了学习平台的交互体验,而且该技术也可用于远程办公、在线互动游戏的开发中。

Research and Implementation of an Interactive Learning RIA Platform Based on Silverlight

To solve the problems of inadequate expression and poor interaction of the current WEB learning platforms,based on the analysis of RIA (Rich Internet Application) and combines with the technical characteristics of the RIA clients with the ability to describe many media elements, an interactive WEB learning platform and the related overall architecture are presented. The handwriting and handwriting recognition method in the WEB environment are realized based on Silverlight and the WCF technology. By exploiting the logic control properties of RIA on the client, the object dragging and collision detection functions are carried out, and these functions are used to design the RIA platform for interactive learning systems .The handwriting and handwriting recognition technology not only enhance the interactive experience of learning platforms, but can also be used for remote office and on line interactive game development.
