What are AI Digital Humans? How Do They Work?

AI Digital Humans have emerged as a groundbreaking technology that combines the best of AI, computer graphics, and natural language processing.

It’s now possible to create nearly lifelike figures who can perform realistic gestures, actions, and deliver real-time animated movements. Motion-based and emotion-expressive avatars are becoming increasingly popular and human-like.

What are AI Digital Humans?

AI Digital Humans are computer-generated characters that look, speak, and behave like real humans. They are designed to engage in natural, lifelike conversations and interactions, mimicking the nuances of human communication.

Unlike traditional chatbots or virtual assistants, which are often limited to text-based interactions, AI Digital Humans have a realistic visual appearance, complete with facial expressions, gestures, and lip-syncing.

These virtual beings are powered by sophisticated artificial intelligence algorithms that enable them to understand and interpret human language, recognize emotions, and provide context-aware responses.

Their fluency includes open-ended conversations, answering questions, providing information, and even offering personalized recommendations.

What Do Digital Humans Do?

Through lifelike expressions and natural conversations, digital humans build stronger relationships with viewers than traditional video or text. The goal is to closely recreate a sense of human connection, on an emotional level.

Organizations are jumping on the train by creating 'mascots' or personalities that provide a digital face for their brand.

Kind of like Amazon's Alexa.
