由于很难从连续的媒体对象（如视频和音频）中找到合适的内容，我们需要开发适当的索引方法。在本文中，我们将讨论的方法，利用“行动历史视图”检索适当的内容，从连续的媒体对象。在屏幕上显示的用户动作的历史记录为符号形式的称为“动作历史”的列表，并且动作历史的每个元素由时间戳标记。动作历史视图机制处理在屏幕上观察到的这种动作历史。当连续媒体对象与动作历史同步生成时，我们可以使用它们来搜索连续媒体对象的适当部分。可以选择满足指定条件的记录动作序列，并与相应的连续媒体对象一起同步回放。在本文中，我们将讨论基本机制及其应用于远程教育。
As it is very difficult to find proper contents from continuous media objects such as videos and audios, we need to develop appropriate indexing methods. In this paper we will discuss methods utilizing "action history views" for retrieving proper contents from continuous media objects. Histories of users' actions shown on a screen are recorded as lists called "action history" in a symbolic form and each element of an action history is marked by a time stamp. The action history view mechanism deals with such histories of actions observed on screens. When continuous media objects are generated synchronizing with action histories, we can use them to search proper portions of continuous media objects. Recorded sequences of actions satisfying specified conditions can be selected and played back together with the corresponding continuous media objects synchronously. In this paper we will discuss basic mechanisms and their applications to distance education.
