What are digital humans, and why are they important? Here's the Ultimate Guide to Digital Humans with all the answers. From healthcare to gaming, discover the many use cases for this innovative technology.

In today's digital age, technology has revolutionized communication between businesses and customers. One exciting development in this area is the creation of digital humans. Computer-generated characters that sound and look like real people and can interact with users in real time. This article explores the concept of digital humans, the technology behind them, their potential use cases, and the steps to create them.

What are digital humans?

Digital humans are AI-powered virtual representations of people that mimic real-life individuals using advanced artificial intelligence and natural language processing (NLP) technologies. They interact with users in real time, providing a more realistic and engaging user experience across various digital channels. With the increasing popularity of the Metaverse and new technology advancements, digital humans play a crucial role in shaping the future of virtual interactions. Digital humans can take the form of chatbots, virtual assistants, or avatars, offering various levels of interaction, functionality, and visual representation. They cater to a wide range of use cases, such as customer support, social media brand ambassadors, healthcare providers, and more. By integrating conversational AI, digital humans can understand user inputs, respond intelligently, and create a personalized customer journey. As digital human technology continues to evolve, the line between real people and their virtual counterparts is increasingly becoming blurred. High-quality digital humans look and sound like real people and can learn and adapt to user preferences, thanks to advanced AI algorithms and extensive training datasets. These digital beings enhance customer experience across digital channels and can even contribute to improved conversion rates and overall brand reputation.

What is the tech behind digital humans?

At the core of digital human technology are three main components: natural language processing (NLP), computer vision, and text to speech synthesis. Natural language processing (NLP) enables digital humans to understand and interpret human language in real time. This AI-powered technique uses algorithms to process text input, extract meaning, and generate appropriate responses. NLP is essential for creating an engaging, human-like conversation between users and digital humans. Computer vision is another crucial aspect of digital human technology. It involves using AI algorithms to create, analyze, and manipulate visual representations of human beings. Advanced computer vision techniques help generate realistic avatars, facial expressions, and body movements that closely resemble those of real people. These realistic visuals create a more immersive user experience and enhance interactions within the Metaverse and other digital channels. Text to speech synthesis is the technology that converts the text generated by NLP algorithms into natural-sounding human speech. By employing AI-powered voice synthesis solutions, digital humans can produce a wide range of speech patterns, accents, and voice tones, making their interactions with users even more authentic. In addition to these core technologies, digital humans also rely on integration with APIs, SDKs, and other AI tools to enhance their capabilities and enable seamless integration with various platforms and applications. Providers like Microsoft, OpenAI (ChatGPT), and Uneeq offer state-of-the-art technology solutions that help businesses and individuals create high-quality digital humans tailored to their needs and demographics.

Potential use cases and integrations for digital humans

  • Virtual assistants: Digital humans can act as intelligent virtual assistants that can help users navigate various tasks, such as scheduling appointments, answering FAQs, and providing personalized recommendations.
  • Video games: AI technology can create more realistic non-playable characters (NPCs) in video games. By incorporating natural language processing (NLP) and machine learning algorithms, these characters can respond to speech and player actions in real time, enhancing the overall gaming experience.
  • Customer support: Digital humans can also be integrated into customer support systems to handle simple queries and provide efficient assistance. For example, a retail brand might use a digital human as a chatbot on its website to answer questions about products, track orders, and provide information about the brand.
  • Healthcare: Digital avatars can provide patients with information about their medical conditions and even offer therapy. For instance, a mental health clinic might use a virtual therapist to help patients manage their symptoms.

The steps for creating a digital human

Determine what the digital human needs to do

As a first step, identify the primary tasks and goals your digital human should accomplish. Consider the specific use cases and industries it will serve.

Understand with whom the digital human will interact

Next, you need to consider the demographics of the users who will interact with the system. What are their needs and preferences? What tone of voice will resonate best?

Choose the right platform for creation

There are many platforms available for creating digital humans, each with its own strengths and weaknesses. Some popular options include Uneeq, Microsoft, and ChatGPT. Choosing the right platform is essential as this can affect the quality, capabilities, and integration of the resulting digital human.

Design conversation flows

The conversation flow is the backbone of the digital human's interactions with users. It's important to design a conversation flow that is natural and intuitive, incorporating conversational AI and NLP to create a seamless user experience.

Avoid the common mistakes of digital human implementation

Finally, it's important to avoid the common mistakes of digital human implementation. These include inadequate testing, unrealistic expectations, and poor integration with existing systems. Additionally, it's crucial to ensure that the digital human's tone of voice and language are consistent with your brand identity.
