FRIEND Engine: Open-Source Virtual Character Platform
An open-source software platform for building interactive virtual characters that perceive users through sensors like cameras and microphones, engaging in real-time dialogue.
What is FRIEND Engine?
FRIEND Engine is an advanced open-source software platform developed by Anthropic for creating interactive virtual characters with conversational AI capabilities. It allows developers to build virtual agents that can perceive users in real-time through sensors like cameras and microphones and engage with them through natural language dialogue.
Some key features of FRIEND Engine include:
- Integrated speech recognition and natural language understanding pipeline powered by techniques like transformers and self-supervised learning to enable rich conversations.
- Multimodal perception of users by connecting AI sensors like cameras, microphones and more as sources of input.
- Virtual character animation system for generating human-like facial expressions, lip synchronization to speech, gestures and full body motion.
- Tools for defining a character's personality, memory and managing long-term conversations.
- Secure interaction mechanisms built with privacy in mind.
- FRIEND Engine handles all the complex AI so developers can focus on designing unique personalities, appearances and conversational content.
- Compatible with popular VR/AR headsets for creating immersive experiences.
With its capabilities for supporting adaptive long-form interactions, extensibility via Python APIs and integration support for various sensors and devices, FRIEND Engine enables developers to create sophisticated AI virtual characters for applications ranging from digital assistants to metaverse avatars and social companions.
