Growing neural gas for information extraction in gesture recognition and reproduction of robot partners

One of the great problems of the aging of society is the increased number of elderly people who live alone and separate from their children. Such elderly people often do not even experience daily conversation, and this can lead to cognitive decline and a high risk of dementia. Human-friendly robots can be used to support the mental and physical care for elderly people. Robotic conversation can activate the brain of such elderly people and improve their concentration and memory abilities. However, voice recognition is not enough in the daily conversation, the recognition of human gestures is also important in order to perform smooth communication. In this paper growing neural network is applied for information extraction in gesture recognition and reproduction by robot partners.
