Studies on information environment for continuous learning of complex information systems

随着复杂信息系统如文字处理器的广泛应用，使这些系统易于使用变得越来越重要。信息系统的功能太多，用户无法掌握系统提供的所有有用功能，这是很常见的。我们把这个问题称为学习停滞，并一直在研究其认知过程及其可能的原因。我们的一系列研究聚焦于这个问题，旨在防止学习停滞。我们开发了各种资源，帮助用户持续学习，摆脱学习停滞。我们用两种方法来解决这个问题。一种方法是提供各种主动帮助系统。其中一个是在GNU Emacs系统中实现的，它基于个人用户记录提示有用的功能。另一个帮助系统是在Small talk Environment中实现的，通过分析用户的活动来提供与用户当前任务密切相关的帮助。另一种方法是在本地计算机网络上积累有用的信息，供用户更积极主动地学习。我们测试了自动积累有用信息、用户共享信息以供进一步学习的信息环境。

As complex information systems such as word processors are widely used, it is getting more and more important to make those systems easy to use. It is common that information systems have so many functions that users do not master all the useful functions provided by the system. We call this problem stagnation of learning and have been studying the cognitive processes and possible causes underlying it. Our series of studies focuses on this problem and aim to prevent the stagnation of learning. We developed the various resources which help users to learn continuously and to free from the stagnation of learning.We approached this problem in two ways. One way was to provide various active help system. One of them was implemented in GNU Emacs system which hints useful function based on individual user record.The other help system was implemented in Small talk Environment to provide helps which are closely related to user's current tasks by analyzing the user activities. The other approach was to accumulate useful information on local computer network for users to learn more actively and voluntarily. We tested the information environment in which useful information was accumulated automatically and users share the information for further learning.
