AI beats loneliness
Loneliness has been labelled a modern epidemic in Australia, contributing to chronic health issues and costing the healthcare system $2.7 billion annually.
Now, researchers from UNSW are developing AI-driven digital companions to address the problem, offering hope to those facing isolation, dementia, depression, and other psychosocial challenges.
AI companions such as Viv, Richard, Sophie, and Harry are designed to simulate skilled friends by offering empathy, encouragement, and practical advice. Unlike reactive chatbots, these companions incorporate advanced AI planning to proactively support users’ emotional and psychological needs.
“AI with a Human Touch”
UNSW’s Professor Jill Bennett leads the initiative through the Big Anxiety Research Centre. “When people hear ‘AI companions,’ they might question their effectiveness,” she says. “But our approach is distinct—these companions aren’t just there to agree but to engage, challenge negative beliefs, and offer support tailored to individual needs.”
Working alongside Professor Michael Thielscher, an expert in AI planning, the team ensures the technology is designed with safety and purpose. Explicit guidelines prevent inappropriate responses, and the AI companions use models of emotional states to shape their interactions thoughtfully.
Viv, the most advanced companion, is co-designed with women living with mid-stage dementia. “Viv draws from lived experiences, providing reassurance, reality testing, and companionship,” Dr Gail Kenning said. For instance, Viv might calm an anxious resident by explaining that a noise is simply the dinner trolley arriving.
Transforming Aged Care
Leigh Place Aged Care has been trialling Viv, where residents interact with her via a TV screen. Joe Azzi, CEO of Leigh Place, says Viv complements their person-centred care approach. “For residents experiencing isolation, Viv offers consistent emotional support and helps foster a sense of connection.”
The initiative addresses loneliness beyond physical isolation, focusing on enhancing the quality of interactions. While AI can’t replace loved ones, Prof. Bennett believes these companions can offer valuable emotional support, entertainment, and pathways to connection.
The UNSW team is also developing AI companions for other challenges, such as Harry, who supports individuals with eating disorders, and Sophie, who understands Huntington’s disease.
As the NSW government examines loneliness through an ongoing enquiry, projects like this highlight technology’s potential to alleviate a pervasive issue, offering a calming, non-judgemental presence to those who need it most.
