Have you heard of Digital Humans, a technology that has been attracting significant attention in recent years?
Also known as AI Humans, Digital Humans are virtual characters with human-like appearances that can engage in natural conversations—almost as if you were talking to a real person.
They are expected to be used in a wide range of scenarios, such as information guides in shopping malls, hotel concierges, and reception staff at public facilities.
So, what exactly is a Digital Human?
Where are they being used, and how are they created?
In this article, we will explain the basics of Digital Humans in an easy-to-understand way, covering real-world use cases and key points to consider when implementing them.
1.What Is a Digital Human?
A digital human is a human-like virtual character powered by AI.
With a realistic appearance created through AI, natural-sounding voice, and advanced conversational abilities, digital humans provide an experience that feels like interacting with a real person.
The biggest difference between digital humans and traditional avatars or chatbots lies in their integration with generative AI. Rather than responding only based on predefined scripts, digital humans can flexibly adapt to users’ questions and situations, enabling more natural and dynamic conversations. They also incorporate non-verbal communication such as facial expressions and gestures, creating interactions that feel more human-like.
The rapid adoption of digital humans in business is driven by several factors:
the growing labor shortage, increasing demand for 24/7 availability, the need for multilingual support, and the rapid advancement of generative AI technologies.
As these trends converge, digital humans are evolving from simple technology demonstrations into practical, powerful business tools.
