A robotic seal has helped to improve the quality of life of dementia sufferers.
Researchers claim that interacting with a therapeutic robot companion made people with mid to late-stage dementia less anxious and also had a positive influence on their lives.
The robot is fitted with artificial intelligence software and sensors that allow it to respond to touch and sound as well as show emotions. It can respond to frequently used words.
The pilot, on 18 participants in Australia, showed that the robots had a clinically meaningful influence, including increased levels of pleasure and reduced anxiety.
