Abstract
In this paper, Time-Command Fuzzy Information and a method of presenting the information are proposed to support human's operation of dynamic system. The concept of Time-Command Fuzzy Information is time-axis-extension of Fuzzy Instruction, which is a fuzzy set of control input candidates and their membership value. Time-Command Fuzzy Information is presented by utilizing melodious expression based on functional harmony. In order to examine the support performance of proposed method, a train driving training system which supports trainee by presenting Time-Command Fuzzy Information is constructed. The results of the experiment demonstrate that proposed method is effective in human-vehicle interaction.
