摘要： 针对虚拟环境中用户认知负荷较重和资源分配不协调问题，综合分析了人脑认知
活动中信息的显性化表达，提出一种基于分布式认知的信息可视化资源模型。通过计算机感知
虚拟环境中用户动作、行为、任务等信息，依据资源分配方案确定资源和信息之间映射关系，
并以信息表象的形式贮存；通过对信息表象进一步精致化，实现交互界面视觉元素的优化布局；
本文结合眼动追踪设备对VR 系统原型进行可用性评估实验，实验结果表明该可视化模型能够
降低用户认知负荷，改善用户体验。

Abstract: An information visualization resource model based on distributed cognition was proposed
to solve the unequal user cognitive load and resource allation problem in virtual environment, with
the analysis of information explicit expression in human brain cognitive activities. The system obtains
user action, behavior, task and other information in virtual environment based on the computer-aware
technology. Resource allocation scheme was used to optimize the mapping between resource and
information, and stored in the form of information imagery. The information imagery was riched by
imagery library to optimize the visual elements of interactive interface. The usability evaluation
experiment about virtual reality system prototype were carried out on eye tracking equipment. The
experimental results demonstrate that the visualization resource model is realized to decrease user’s
cognitive burden and improves user experience.

Key words: distributed cognition, information visualization, virtual reality, resource model, human-computer interaction
