Lenovo unveils an AI-powered 3D avatar to support dementia care

Chinese-American multinational technology company, Lenovo, in collaboration with UK-based community interest company (CIC), Innovations in Dementia, has launched Alzheimer’s Intelligence, an innovative proof-of-concept project featuring a photorealistic 3D avatar designed to assist individuals diagnosed with dementia and Alzheimer’s. The AI-based avatar, named “Liv,” offers a 24-hour conversational resource that provides curated advice grounded in real-life experiences, prioritizing accuracy, privacy, and compassionate interaction.

This pioneering application leverages Lenovo’s comprehensive technology solutions, combining generative AI, large language models (LLMs), and advanced visual AI. Liv’s persona is created from a composite of images and experiences of 10 people living with dementia, enhanced through generative AI to form a responsive, realistic avatar capable of unscripted, natural conversations.

The knowledge base for Liv is built from first hand advice and entries from Innovations in Dementia’s “Dementia Diaries project”, as well as panel interviews. Users interact with Liv using speech-to-text input, and responses are tailored using sentiment analysis, which guides the avatar’s facial expressions for a more empathetic experience.

Liv allows users to ask questions about daily challenges, new hobbies, or discussing their condition with family members, drawing from authentic lived experiences rather than scripted medical advice. The tool is designed for ease of use, requiring minimal tech expertise and mimicking familiar, natural conversations.

Currently in trial with controlled user testing, the project aims for wider availability in the future, while ensuring clear guardrails to prevent medical misinformation. The development utilized Lenovo’s AI-ready solutions, including workstations and cloud services, and involved tech partner Kaleida.
