AI-Generated Avatar
AI-generated avatars let anyone create high-quality video content without needing actors, lighting, or cameras. These “digital humans” powered by artificial intelligence deliver highly realistic, lifelike virtual interactions. They are easier than ever before to create, with the help of top-level platforms, that simply require choosing settings from a menu and adding text-based content to control the avatar’s actions. Modern techniques allow for picking personalized appearances and voice styles ranging from cartoonish to human-like. These AI-generated avatars serve many purposes today across industries and applications for big businesses and amateurs alike.
What Is an AI-Generated Avatar?
An AI-generated avatar can be formed in the image of a real person, a human archetype, or an imaginary character. Artificial intelligence technology is used to:
- Build the appearance of the avatar through user prompts. For example, the ChatGPT image generator can create characters using text input (often combined with a graphics plug-in).
- Animate the avatar according to user instructions. For instance, Canva can transform a static image into a dynamic one simply by choosing from an animation menu in the interface.
- Direct the actions of the avatar according to a script. For example, D-ID enables users to upload a textual knowledge base translated by AI into what the avatar says and does on-screen.
- Interact in real-time with an actual person. Generative AI, combined with a knowledge base, can be used along with other advanced technologies for programming the avatar to understand and reply to queries from a person.
The nature of AI-generated avatars has changed dramatically over the years. Creating one used to require professional animation tools simply to form an image. To convert this into something dynamic, powerful computing platforms were necessary to build a video in what was essentially a frame-by-frame process.
Today, an AI-generated avatar video is built using widely available and relatively inexpensive tools. We mentioned ChatGPT and Canva, but many other technologies can be used, depending on the application.
Applications of AI-Generated Avatars
Any industry that uses video media will find an application for AI-generated avatars and videos. There are essentially two formats:
Interactive – AI avatars that understand questions and deliver responses are used for customer service, gaming, marketing, and sales activities. Some avatars are programmed to react as medical patients to train physicians.
Unilateral – Non-responsive avatars have been designed as content presenters in the form of hosts, narrators, influencers, bloggers, and guides for tourism and hospitality. Similarly, they can be used as actors in a virtual film. In education, avatars can serve as teachers and instructors for students and employees.
How AI-Generated Avatars Work
So, how do you get from the initial idea of an avatar into a moving, speaking character? That’s where sophisticated technologies come into play. These include:
Facial recognition
When actual images of people are used, AI processes the features into something it understands. The details of the eyes, nose, mouth, facial shape, and skin color are processed to be changed and manipulated for duplication and movement. Many facial recognition techniques use 3D modeling to provide essential depth characteristics.
AI animation
The purpose of the avatar is to move and speak. To appear lifelike, it is not enough to lip sync with whatever text is used to determine what the avatar does. Through years of development, experts have analyzed the complex movements of actual people and used this information to “teach” artificial intelligence programs how to behave. A well-rendered avatar will blink naturally, move various parts of its face, and have mouth movements that are highly coordinated with whatever words are being spoken.
Interactivity
Enabling an avatar to receive, process, and respond to queries while maintaining a human appearance requires a whole additional level of technology. These include:
- Machine learning for processing queries
- Retrieval-augmented generation for accessing information from a range of sources
- Generative AI for turning the answers to queries into something that can be understood by a person
- Natural language processing that allows questions and answers to use normal expressions instead of a defined set of terms
How to Create an AI-Generated Avatar
It has never been easier to create and animate a basic avatar. Tools like ChatGPT allow you to build endless iterations simply by adding more definition to your original prompt. Some platforms create an AI-generated avatar from a photo sample on your device or from the internet as long as it meets the right specifications. Some creators even process an actual photo through an AI engine to obtain a result that is part actual and part generated, which gives the appearance of an animated version of a real person.
The level of customization and sophistication depends on the platform. On the one hand, there is DaVinci AI, which focuses on highly artistic visual creations of avatars (among other things), but without animation capability. In comparison, the D-ID Creative Reality Studio provides an intuitive GUI and many menu options to adjust the appearance of a dynamic avatar to your needs. In fact, D-ID invites artists worldwide to create and submit unique avatars, either by using the Studio, or their software. It also supplies AI-generated talking avatars, along with various voice types and the ability to auto-translate the text of the knowledge base.
For those creators who want to take their avatars a step further, two important factors make advanced avatar building into a highly complex operation:
Quality Level
Some creators want avatars that are as close to human-like as possible. This means incorporating extensive facial characteristics, highly lifelike movements, and close attention to very minute details of the eyes and mouth. This level of programming requires special tools and a lot of processing power.
Activity Level
It is similar to the story of how much movement the avatar uses. A “talking head” avatar that sits and verbalizes text will not require complex development. However, a rapidly moving, full-body avatar, complete with clothing, light effects, and detailed background, demands powerful computer systems and a lot of design expertise.
