Shingo Kinoshita, Senior Vice President, Head of Researchand Development Planning, NTT Corporation▼Abstract

In 2023, NTT Group announced its new medium-term management strategy: “NewValue Creation & Sustainability 2027 Powered by IOWN.” To execute this strategy,
NTT laboratories are committed to pursuing the world’s best research anddevelopment (R&D) under the following guiding principles: keep researchers
motivated and excited, research and develop powerful technology to benefit society
in a scalable and sustainable manner, create the future rather than predict it, andnurture intuition and be creative. We interviewed Shingo Kinoshita, NTT senior vicepresident, head of Research and Development Planning, about the strengths ofNTT’s R&D and his mindset as a top executive.

FleEven a seasoned baseball pitcher has difficulty throwing a ballto the same location repeatedly. Such movement variability is
assumed to come from neural noise, which causes the muscle
activity’s amplitude to fluctuate between movements. We
explored an alternative source of noise, namely the variability
in the muscle activity’s timing. We constructed acomputational model of a shoulder controlled by two muscles
then varied the muscle activity’s amplitude and timing
independently to predict their effect on the shoulder’s force.
These predictions were then tested by recording the muscle
activity from human participants who used their shoulder toproduce periodic forces. The force’s variability was explained
more accurately by timing noise, suggesting that variablemotor timing could play an important role in determining
movement precision.
