Meet Richard, Lou, Viv, Sophie, Harry, and Willow - the digital companions designed to help older Australians battle social isolation, anxiety and dementia. The six artificial intelligence (AI)-powered companions developed by researchers from the University of NSW can interact with and support people's needs in numerous situations. Interactions between humans and AI technology are commonplace, but Jill Bennett - head of the university's Big Anxiety Research Centre - said these were not just your typical chatbots. "These characters aren't about replacing human interaction, they're about supporting and encouraging people through difficult situations," Professor Bennett said. Professor Bennett said most chatbots were programmed to provide support and affirmation by agreeing with their human companion.

"Let's say someone is lonely ... they're saying, 'I don't want to go out, everybody hates me, life's not worth living. "What you ideally want is someone who can challenge those thoughts and beliefs and open up options." The companions can also offer a sympathetic ear and friendship to those with limited social options. "A lot of people are very lonely in aged care because even though there are loads of people around, they're not [their] chosen friends." The AI companions are programmed to listen to people's thoughts and frustrations. They can also draw on data to offer expert advice for those concerned about their medications or the advice they are receiving. Different companions have been developed to offer support to people in various situations. The most well-developed so far is Viv, who was created in consultation with people with mid-stage dementia. Viv can advise those who feel confused, disoriented, or unaware of their surroundings. "For someone who's recently diagnosed with dementia or has all the concerns that people with dementia have, she's like a friend in the same situation." Richard has been developed to help those who have lost confidence due to a fall. He portrays a blokey former football player who recently had a fall while attending a game. "[He] is proving quite helpful with men who would be kind of mortified in that situation. "They're not going to ask for help; they're certainly not going to sign up for therapy. But this guy can offer tips and good advice." Companions can also offer support for other psychological challenges, including milder cognitive impairments, eating disorders and mental health issues. Viv has been trialled at Leigh Place Aged Care. Chief executive Joe Azzi said Viv had shown the potential to complement the home's person-centred care approach. "For residents who may experience feelings of isolation, Viv provides an always-available conversation partner, helping to alleviate loneliness and support a sense of connection," he said.
