Mr. Hara faced many obstacles during the development of QR Code, but overcame them with various ideas. The first problem was that the code could not be read accurately due to ink blotches. The clue to solving this problem came from his childhood love of Go. In Go, it is enough to recognize the location of stones by the color and position of surrounding stones, and it does not matter if a stone is missing or slightly out of position on the board. We thought, "Why don't we blur the boundary between black and white and let the code read the information roughly first, and then fine-tune it to recognize the stones again? We tried it, and it worked. He says that it is important to dare to look at things from a different point of view because one's perspective tends to become narrow when immersed in development.
When we asked Mr. Hara why QR Code has spread so widely throughout the world, he replied that it was because it is license-free. No matter how good the technology is, it is meaningless unless many people use it. I am happy that so many people are using it," said Mr. Hara.
