The study of visual illusion has been ignoring the awareness or qualia of illusion. However, the perception of visual illusion is based upon the awareness of illusion (Tanaka, 1998, 2000). If observers are not aware of the discrepancy between the physical feature and the appearance of an object, the distorted image is not at all illusion. Qualia are also related to illusion. Actually, illusory figures give several pieces of qualia specific to illusion, e.g. "beauty" (Noguchi & Rentschler, 1999) or "motion feeling". Yet the transmission of the qualia to other people might be difficult since qualia are just subjective. Thus, those who try to study illusion in terms of consciousness need not only abilities of art and science but also the ability of "rhetoric".
