A new technology called "human augmentation" is attracting attention. Rather than simply using hi-tech machinery to assist with activities and daily life, it will need to give humans the feeling that they themselves are actually operating a machine or device, while also providing the sensation that their actions are influencing their surroundings. The key point is computer-mediated interaction between one human and another, or between humans and society. Scientists say that, if humans' ability to operate machinery based on this approach increases, it might one day be possible to engage in completely different endeavors than has been the case until now, even in the fields of health and nursing care.
