In some cities, convenience-store employees obtain real-time notifications – a sort of group security internet that may find a lacking particular person inside hours.

Different applied sciences purpose to detect dementia earlier.

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

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

“It requires full-body sensing and adaptive understanding – methods to regulate for every particular person and state of affairs,” he says.

Emotional help can also be a part of the innovation drive.
