Recently, a number of commercial ventures have been launched that offer social robots as personal home assistants, perhaps eventually to rival existing smart-home assistants.
(A)
They might be motorized and can track the user around the room, giving the impression of being aware of the people in the environment. Although personal robotic assistants provide services similar to those of smart-home assistants, their social presence offers an opportunity that is unique to social robots.
(B)
Personal robotic assistants are devices that have no physical manipulation or locomotion capabilities. Instead, they have a distinct social presence and have visual features suggestive of their ability to interact socially, such as eyes, ears, or a mouth.
(C)
For instance, in addition to playing music, a social personal assistant robot would express its engagement with the music so that users would feel like they are listening to the music together with the robot. These robots can be used as surveillance devices, act as communicative intermediates, engage in richer games, tell stories, or be used to provide encouragement or incentives.
