A Dialog Based Interactive Robot
Recently the research in robotics has started to focus on the development of service robots that serve people in natural office or home environments, e.g., robots for household work, as tour guide or for elderly care. Such a robot has to exhibit cognitive capabilities such as to understand human activities and to behave socially. Two of the key issues in realizing these ambitious goals are recognition of user attention and multi-modal dialog management. In the following we are going to take a closer look at these two points with the implementation of the home-tour scenario as example.
