Supporting a Well-being Society that Integrates the Digitaland Real Worlds▼Abstract
After reviewing the spread of digital technology
in society that has accompanied thedevelopment of information andcommunication technology, this article
introduces a well-being digital-real fusion
society that is necessary today, and the efforts
being made by NTT laboratories to achieve it.

(1) Social well-being
6. Self-transcendence

Altruistic coexistence of individual autonomy and collective
harmony centered on the digitization of society(3) Human digital twins

03: Individual

5. Desire for self-realization
4. Desire for approval
3. Social desire

Support self-actualization andsensory communication basedon the digitization of people

02: Society/group

2. Desire for safety

01: Life/body

1. Physiological desire(2) Lifelong health support

Support lifelong health by visualizing body rhythms basedon the digital representations of the human body(4) Human information science

Maslow’s hierarchy of needs

Understanding and intervening in the essential nature ofwell-being, centered on basic research of humans(a) The hierarchy of well-being(b) Initiatives of NTT laboratories

Communication Science that Adapts to the Changing
Present and Creates a Sustainable Future—Aiming to Create
Technology that Brings Harmony and Symbiosis among
People, Society, and the Environment▼Abstract
NTT Communication Science Laboratories (CS Labs) celebrated its 30th anniversary in 2021. From thebeginning, we have been engaged in research to construct basic theories that address the essence ofhuman and information sciences and develop innovative technologies that can bring about changes insociety. We aim to achieve communication that “reaches the heart” between humans and between humans
and computers. In this article, I present the recent research results at CS Labs and efforts toward futureadvances.
