A new visualization method to help users recognize sleep state misperception is proposed based on hypotheses: (1) that a graphical visualization method can help users become aware of sleep state misperception, and (2) that motivation for continued use can be improved by introducing a qualitative visualization approach. In this method, gaps between subjective and objective evaluations are represented using Mondrian-like abstract graphic patterns. To verify these hypotheses, experiments were conducted and the results were analyzed. The findings support both hypotheses. Hence, the proposed method is comparable to traditional methods and offers an advantage in terms of sustained use.
