移动学习就是通过移动设备实现在任何时间、任何地点进行的学习;然而移动设备间的差异性很大,处理平台的异构性可使不同的移动设备支持不同课程资源显示格式。为了使移动设备可以像PC机一样获取网络课程资源,适应异构的移动计算环境,作者重点讨论了如何利用Agent技术建构设备自适应系统模型,实现资源格式的自动转换。 Mobile learning is a learning process that takes place on mobile devices anytime, anywhere. However, the differences between mobile devices are so great that dealing with the heterogeneity of platforms makes it possible for different mobile devices to support the display of different course resources. In order to enable mobile devices to acquire online course resources like PC, and to adapt to heterogeneous mobile computing environment, the author focuses on how to use agent technology to build a device adaptive system model and realize the automatic conversion of resource formats.
