Abstract:

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.
