OCR stands for "Optical Character Recognition". The OCR-B font, designed by Adrian Frutiger and easily recognizable by both AI and humans, is deformed to different sizes and tilts, distributed from the upper left to the lower right of the image, and masking is applied to the thermograph printed on the mirror, which has been used for many years as a daily commodity since ancient times. The masking process is performed. Characters that have undergone this process are not recognized as contiguous blocks in the OCR process and cannot be read as characters. On the other hand, humans can correct and interpolate these distributed "fluctuations" and recognize them as continuous numbers, such as 36.6. The day will come when humans will no longer be able to win. We all fear somewhere that it will mean the end of chess. ...At that time, all we have to do is change one rule, and the elucidated answer will be far away, and a new question will come up again." -Baku Yumemakura, Takeru Kaido, and Yusuke Kishi, "Document Den-Ou Sen" (2013) from Zenji Hanyu Meijin's statement Hirasawa is a great master of AI and Hirasawa draws a boundary in the ambiguity between AI and humans, which he has been exploring, by skillfully manipulating the relationship between AI and humans by combining "Characater" and "Character" and "recognition of 'person' by optics" in this way.
