Development of Mapping Function between Variable Value and Object Properties for Program Behavior Visualization Tool TEDViT

Abstract

TEDViT is a program behavior visualization system that can reflect explanatory intentions of a teacher by visualizing it in a target world. This system can dynamically reflect changes in variables caused by program behavior in terms of numerical values on objects. However, it is difficult to map the variable values to the position, size, and color of the object. In this study, we implemented a function in TEDViT to dynamically map variable values to object properties. We report an experimental evaluation using 10 subjects.
