Iwata Asks," a series of articles in which Nintendo president and CEO Satoru Iwata interviews colleagues about their recent work, Shigeru Miyamoto finds himself discussing the origins of Wii Fit. Much like Pikmin and Nintendogs before it, the popular balancercise board has its roots in Miyamoto's everyday life. After a hectic work schedule heaped pressure and extra pounds onto the renowned designer's body, he swapped smoking for swimming and steadily grew more conscious of his body and his weight.
Next came a special diet which required frequent measurement and recording of body weight. "Personally, I quite enjoy doing things that become habitual, as if it was daily routine work," explains Miyamoto. "I put the scale and graph paper in the bathroom, and after continuing the pattern for a month, it became like a ritual before getting into the bath. I wasn't able to relax without doing it!" Transforming the habitual measurement into something fun was the next step, one that preceded months of prototyping and "upending the tea table" -- a reference to Miyamoto's tendency to make last-minute decisions and cause a panic right before a deadline.
