Six-axis sensors detecting fluctuations in the axis of the body when walking or playing sports, and the applications will vastly improve the "life performance" of humanity.

I’m Takeshi Hashimoto. I apply gait analysis primarily through motion capture systems to studies on how humans walk, what kinds of problems arise as a result of walking, and what we can do to prevent such problems.

These JINS MEME glasses come with accelerometer and gyroscope sensors. With these sensors, we can find out how much the body wobbles when an athlete walks, or whether their left-right balance is off. If we can figure out how to eliminate or prevent such problems, we can prevent injury and raise sports performance levels. These are two important things that make JINS MEME significant.

In the fields of gait analysis and motion analysis, we have a system for analyzing movements in details by placing reflective markers on a subject for motion capture. Another system is a simplified method of measurement like JINS MEME. Motion capture gets you precise data, but you need very large equipment. It’s not easy to use in everyday situations. In contrast, since JINS MEME is small and can constantly remain on the body, an athlete’s behavior can be tracked 24 hours a day. Thus, you can see how the athlete has behaved in various situations in real time and learn what sort of exercise he or she has done. That’s why I think collecting this data is so important.

The part of the body that moves the least is the head. If you place a sensor there, you can pick up movements with the least amount of interference. The word MEME comes from the word gene. That’s why I want to save a lot of human gait data for future generations while properly ensuring the privacy of test subjects. By passing along the vast data that we can collect through these glasses about what kinds of people develop problems and what kinds don’t for future generations, I believe JINS MEME will be truly fulfilling the function it was meant to serve.

Takeshi Hashimoto

As Associate Professor at the Keio University School of Medicine, Hashimoto graduated from the same school in 1984. In 1986 he completed coursework at National Tokyo Hospital No. 2 (now the Tokyo Medical Center). In 1994-5, Hashimoto studied abroad at the Karolinska Institutet in Sweden as a researcher sent by the Japan-Sweden Foundation. In 1996 he earned academic credit for his Ph.D. in medicine. After serving in such positions as director of orthopedics at Keio University's Tsukigase Rehabilitation Center, Hashimoto has been in his current post since April 2013. His specialties are orthopedics with a focus on leg surgery, the science of shoes and sports medicine.
