“Early detection of age-related illnesses is essential,” says Hidenori Fujiwara, a Fujitsu spokesperson. “If docs can use motion-capture information, they’ll intervene earlier and assist individuals stay energetic for longer.”

In the meantime, researchers at Waseda College are growing AIREC, a 150kg humanoid robotic designed to be a “future” caregiver.

“It requires full-body sensing and adaptive understanding – easy methods to alter for every individual and scenario,” he says.

Emotional help can be a part of the innovation drive.

Poketomo, a 12cm tall robotic, will be carried round in a bag or can match right into a pocket.
