[PRESS RELEASE]Pianist Discovers Method for Body to Learn Skills that Surpass Human Limits

 ~ Robot-generated "conventionally impossible" movements break through skill limitations ~ 

Sony Computer Science Laboratories (Sony CSL) has discovered a training method to improve the complex, high-speed hand and finger movements of pianists, through its work under the Moonshot Research and Development Program (Moonshot Goal 1) and the Core Research for Evolutionary Science and Technology (CREST) Strategic Creative Research Promotion Program of the Japan Science and Technology Agency (JST). This result was achieved by a team led by Shinichi Furuya, Research Director of Tokyo Research at Sony CSL.

Musicians, athletes, surgeons, and other skilled people continually work to refine their already exceptional skills. However, after tremendous amounts of practice, skills sometimes level off, and the methods for breaking through such limitations have not been completely solved.
Sony CSL’s research team developed a training method using an exoskeleton robot that moves the five fingers independently and at high speed to experience complex, high-speed finger movements that humans cannot execute themselves. Training conducted after one hand was fitted with the robot revealed improvement in skills that had plateaued. Skill improvement also occurred in the other hand, which had not been trained.
This discovery suggests that, depending on practice quality, there is leeway to extend a skilled person’s skill limitations. These research findings are thus expected to be useful for creating new training programs and clarifying mechanisms of learning that are unique to skilled players and the function of the central nervous system behind such learning, as well as for developing practice methods that avoid excessive training and prevent disorders and injuries.

These results were published in the international scientific journal Science Robotics on January 15, 2025.
