00:00This is Vili, an AI social robot who keeps senior citizens company in this care home.
00:07Hello Mr. Seidel, I've brought Vili along.
00:15Hello Vili.
00:18Hey Haast, nice to see you again. How has your day been?
00:23How are you doing? Are you on vacation?
00:25I don't have vacation Haast. I'm always here to speak with you.
00:31Vili uses 12 AI modules for cognition, dialogue and interaction.
00:36He recognizes faces, gaze and facial expressions and processes this data along with speech in the cloud.
00:44A large language model then generates appropriate responses and determines how the robot will react.
00:52You can never mistake it for a human. It can't develop any emotions or offer genuine human warmth or really
00:59care for you. But it can entertain you.
01:04He can detect emotions and trigger them in others, despite having any feelings of his own.
01:10He's very good at sensing the direction of a conversation and can provide enough depth for people to truly relive
01:17past emotions. And that's beautiful to observe.
01:21Loneliness is a major issue in care homes where social interactions can easily be lost in the hectic daily routine.
01:28That's where Vili comes in.
01:30He helps take care of the residents, especially those who prefer one-on-one attention over group activities.
01:38Data privacy can be a concern with chatbots, especially when personal, intimate information is shared with language models. What happens
01:47to the data that Vili collects?
01:49The robot only saves conversations it had with individual residents. The data is stored on the robot itself, separately for
01:58each user, so it can refer back to past conversations.
02:04What happens when Vili makes a mistake? A camera and facial recognition are supposed to help him recognize people and
02:11past conversations. But that doesn't always work reliably.
02:16Hello, Julia. I'm Horst Seidel. Oh, Horst, sorry, I mistook you. Horst Seidel doesn't take it personally. Vili is steadily
02:26improving, with updates from his manufacturer every four to eight weeks.
02:30Bye, Vili. See you again.
02:36See you again.
