A Hypersimulation-Based Learnin g Environment : SIMPLE Junich Yoshizawa, Syoichi Muto * Takeo Ueda, Shogo Nishida t Introductio n Hypersimulator SIMPLE is a simulation-base d learning environment (Fig . 1) to enhance operators' understanding of dynamics of comple x systems, such as electric power systems . The hypersimulator is literally a simulator fused with a concept of hypertext . Our system design approac h is an interface-centered approach based on th e characteristics of operators' way of thinking an d cognitive science . Basic Design Requirement s 1. Spatial information : Spatial information, suc h as how loads and generators ar e geographically distributed in power systems , is essential information for operators ' understanding, and also effective for formin g mental models and causal understanding . 2. Qualitative information : Qualitativ e information such as the direction of chang e of the process of power systems is more important than the quantitative one . 3. Multiple views: It is important to provide multiple views of the process, such a s abstract views, hierarchical ones , mathematical ones, etc . Multiple views ar e also effective for avoiding the condition i n which operators' attention focuses only on
