The concept of a virtual human encompasses a range of digital representations, each with unique characteristics and functionalities. Understanding these differences is crucial for a comprehensive comparison.
Simple graphical representations: These are often used for online interactions, primarily focused on representation rather than realism.
Limited functionality: Basic avatars lack complex behaviors or interactions beyond predefined actions.
Examples: Character selection in online games, social media profiles, and some customer service applications.
Highly detailed and photorealistic models: These virtual humans closely resemble human appearance and behavior.
Advanced AI capabilities: They can exhibit complex emotions, react to situations, and even engage in conversations.
Examples: Virtual assistants, digital influencers, and characters in interactive entertainment.
Representations of real-world entities: Digital twins mirror physical objects or processes, allowing for simulation and analysis.
Data-driven modeling: They are continuously updated with real-time data.
Examples: Simulating the performance of an aircraft engine, modeling the behavior of a city's infrastructure, and using medical data to simulate patient conditions.
Creating a virtual human involves several distinct steps, each contributing to the final representation.
3D modeling: Creating the base structure and form of the virtual human.
Texturing and rigging: Adding details and enabling movement.
Animation and facial expressions: Bringing the virtual human to life through motion and emotion.
Natural Language Processing (NLP): Enabling the virtual human to understand and respond to human language.
Machine Learning (ML): Training the virtual human to learn and adapt to different situations.
Interested:
Emotional AI: Giving the virtual human the ability to exhibit and recognize emotions.
User feedback: Gathering input to improve the virtual human's performance and interactions.
Iterative development: Continuously refining the model based on user feedback.
Performance optimization: Ensuring the virtual human's behavior and interaction are smooth and efficient.
The use cases for virtual humans are rapidly expanding.
Interactive games and movies: Virtual humans are used to create believable characters with complex behaviors.
