Design of cognitive tools for everyday information-based activities

我们生活在一个知识社会。我们在许多活动领域都严重依赖信息。我们大多数的日常活动都涉及到思想和信息。我们被信息的海啸所淹没。与此同时，人们期望我们比以往任何时候都更有效地开展活动。为了科普，我们需要工具。认知工具（CTs）可以提供帮助。这些软件工具位于我们的大脑和数字信息空间之间的界面，并调解两者之间的互动。CT的例子包括交互式数学可视化软件，决策支持系统和数字图书馆。

We live in a knowledge society. We are heavily dependent on information in many spheres of our activities. Most of our everyday activities involve both the mind and information. We are awash in a tsunami of information. Simultaneously, we are expected to carry out our activities more efficiently than ever before. To cope, we need tools. Cognitive tools (CTs) can help. These software tools sit at the interface between our mind and a digital information space and mediate the interaction between the two. Examples of CTs include interactive mathematical visualization software, decision-support systems, and digital libraries.
