In turn, this study tries to analyze various ranging requirements of teachers and experts by doing focus group interview in terms of user affordance and try to suggest the way to improve this system for the sustainable use. Henceforth the results of this study, which includes specific problems of physical, cognitive, sensual affordance and a design prototype to improve these problems, can be an important base material for the process of improving Diagnosis Supplement System for Basic Academic Skill with the effective and intuitive system
