A 3D virtual AI assistant is a computer-generated, three-dimensional representation of a personal assistant powered by artificial intelligence. These assistants are designed to understand natural language voice commands and perform various user tasks. They can be integrated with different technologies such as gesture recognition, image/video recognition, speech recognition, and vast dialogue and conversational knowledge base to increase the interaction between humans and machines.One example of a 3D virtual assistant solution is Pinscreen's AI-driven virtual avatars. Their solution is entirely cloud-based and does not require any game engine on the client side. This ensures high-fidelity renderings independent of which device you are using (mobile, desktop, etc.). All you need is an Internet connection.One of the goals of Artificial Intelligence (AI) is the realization of natural dialogue between humans and machines. In recent years, dialogue systems, also known as interactive conversational systems, are the fastest-growing area in AI.
