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
