In a society that is becoming ever more digitally oriented, our interactions, both personally and professionally, are changing dramatically. The development of technology such as artificial intelligence, 3D rendering, and natural language processing is advancing our capacity to produce virtual entities that are more responsive and lifelike. Presenting AI avatars and digital humans, two of the most exciting new developments that are revolutionizing virtual interaction.
Although AI avatars provide sophisticated and scalable interfaces for digital communication and customer service, digital humans surpass realism by accurately simulating human emotions, actions, and facial expressions. When taken as a whole, they are influencing how consumers will interact with services, companies, and even each other in virtual spaces.
Will digital humans or AI avatars become prominent in how humans interact with digital systems? Let’s focus on the primary differences between AI avatars and digital humans. And explore the technologies behind them, their uses, and why they will shape future virtual communication.

What are AI Avatars?
AI avatars are digitally created personalities. They are brought to life by artificial intelligence. These avatars are different than static images or simple animations. Designed to mimic the facial expressions, emotions, and behaviors of human beings, they are becoming increasingly popular.
AI avatars use machine learning and sophisticated algorithms to understand and respond to inputs. These can be voice, text, or even facial expressions. They are able to replicate discussions in real time, adjust to various situations, and offer customized interactions. AI avatars are essentially the next wave of virtual friends, fusing personality and technology to produce distinctive, captivating online encounters.
Firms in this specific segment are developing creative concepts to reshape the AI avatar era. At the AVANT Special Forces Summit in October 2024, for instance, RAVATAR debuted their Interactive AI Avatar technology. A lifelike, dynamic 3D image of AVANT CEO Ian Kieninger was unveiled as the first-ever AI Avatar Keynote Speaker. The promise of AI-driven communication in producing captivating and perceptive presentations was demonstrated by an AI avatar, which shared the stage with its real-world counterpart.
What Are Digital Humans?
Artificial intelligence (AI)-driven virtual entities known as ‘digital humans’ are made to look and act like actual people and are intended to communicate in ways that are both natural and human, so fusing technology with human emotion.
In contrast to chatbots or basic avatars, digital humans:
- Behaving and looking just like you, with lifelike facial expressions and gestures.
- During conversations, pay attention to what you’re saying and observe the nonverbal clues you use.
- Modify their answers in light of the overall message you provide to make the discussion interesting and personal.
- They do more than just chat; they nod, smile, and act in ways that give the conversation a genuine sense.
- These virtual entities might have several shapes.
- Some are digital twins; exact duplicates of real people that capture their distinct characteristics and actions. Others, created by AI to create new characters, are completely fictitious.
- Regardless of their place of origin, digital persons are here to give our digital interactions a human touch and make them feel as authentic as possible.
What Technologies do AI Avatars and Digital Humans Use?
Both AI characters and the numerous interwoven technologies that support them are highly advanced.
Did you know that NVIDIA made its Avatar Cloud Engine (ACE) generative AI microservices publicly available at COMPUTEX in June 2024? With the help of these microservices, companies in the gaming, healthcare, and customer support sectors will be able to create, animate, and maintain lifelike AI avatars more quickly. Dell Technologies, ServiceNow, and Perfect World Games are among the early adopters using ACE to improve user interactions with digital agents that are human-like and responsive.
This brings us to some fascinating technologies that are enabling firms such as NVIDIA to thrive in this field:
Machine Learning
These algorithms are used to train any artificial intelligence. They provide the AI with the ability to think for itself and develop intelligence. In order to enable the digital human to learn and adjust over time, many of these algorithms should also operate while the person is in use.
Natural Language Processing
The technology known as natural language processing, or NLP, enables an artificial intelligence (AI), in this case, the digital human, to comprehend and interpret written or spoken language and provide pertinent and insightful answers.
Speech Synthesis
Speech synthesis is also a major factor in the realism of the AI since a lifelike AI digital human also need a lifelike voice. Text-to-speech and even speech-to-speech technologies are likely familiar to you. The general term for all of these technologies and many more is speech synthesis.)
Rendering Engine
For a virtual human to look realistic, 3D modeling software is required. The difficulty here is that rendering and displaying the character in real-time requires a substantial amount of processing power, similar to what video game engines require.
Animation & Movement AI
Digital humans in AI movements depend on a variety of cutting-edge technologies. These include of deep learning models trained on human motion, physics-based simulations, and procedural animation systems. When used in tandem, these algorithms allow for realistic gestures, facial emotions, and body language in real time, reacting dynamically to the AI’s speech, ideas, and even interactions. After processing this data, rendering engines bring the virtual character to life.
Computer Vision
Computers can utilize cameras to recognize and react to motions and facial expressions, even if they can’t ‘see’ the way humans do.
You’re not alone if it sounds complicated! Consider it analogous to writing a symphony, in which a variety of components must come together in perfect harmony to produce a seamless experience.
Benefits of AI Avatars and Digital Humans
AI avatars and digital humans can bring several useful benefits to your business. Here are a few key ones:
- Always available: They don’t need sleep or breaks, so they’re ready to help customers 24/7.
- Cost-effective and scalable: As your business grows, they manage more interactions. This means you save money without hiring extra staff.
- Better customer experience: They understand facial expressions and tone. This makes chats feel natural and personal.
