Teddy bear upgraded with an embedded system to react on feelings

摘要

This paper introduces an embedded system placed inside o teddy bear, aiming to implement an intelligent toy. Both parents and children will be benefited from its operations, as it provides emotional observation and paternal monitoring of the child. It is consisted of the Beagleboard-xM single board computer, having a webcam and a speaker connected on it. The webcam is responsible for live streaming video, which is analyzed by a personal computer, trying to detect the child's facial expressions and finally put a song on playback to keep the child happy and mentally awaken and the parent not worrying. The beagleboard can be replaced by any other ARM based single board computer executing Linux and this whole autonomous, embedded system can, from now on, be the pole star to all toys.
