Digital Human

A "Digital Human" refers to a virtual human that combines advanced AI and CG technology, possessing a natural appearance, voice, expressions, and conversational abilities, much like a real person. It can communicate with humans in real-time, express emotions, and learn, with applications spanning a wide range of fields including customer service, education, healthcare, and entertainment. While AI influencers and VTubers often have specific character traits, digital humans are distinctive in their pursuit of a more human-like, realistic presence.

Why is this term gaining attention now?

Thanks to the dramatic advances in generative AI and real-time rendering technology, the production costs of digital humans have decreased, and their quality has improved to the point where they are almost indistinguishable from reality. This has accelerated the adoption of digital humans by companies looking to enhance customer experience, address labor shortages, and strengthen brand image. Our editorial team has been developing and utilizing digital humans as practice partners for meeting presentations, and we are consistently surprised by their natural responses and changes in expression, feeling as if we are talking to a real person.

Cautions and Misuses

Due to their realism, digital humans can also trigger the "uncanny valley" phenomenon. When introducing them in business, it is necessary to consider not only technical perfection but also the psychological resistance users might feel. When using this term, it should be clearly conveyed that it is not just a "CG character" but an "interactive entity equipped with advanced AI." A misuse would be to excessively emphasize the "human-likeness" of digital humans, and to use expressions that might lead to the illusion that they possess consciousness or emotions. It is important to remember that they are ultimately virtual beings advanced by AI technology.
