Information presentation based on estimation of human multimodal cognitive load

Our goal is the implementation of an adaptive system for presenting information in a high cognitive load environment. High cognitive load environment users include car drivers, aircraft pilots and plant operators. We examined models for estimating a user's cognitive load for planning and creating a great variety of information presentation formats, and developed three numerical hypotheses related to cognitive load. It is necessary to examine the tendency of cognitive load for each combination of information presentation formats and each information presentation format as the first step to verify which of three hypotheses is correct. This paper describes an experiment to measure subjects' response to various combinations of information presentation formats. The results suggest that the combination of information presentation format influences the subjects' ability to recognize them and that there is a possibility that each of the three hypotheses is valid.
