This smart doll demonstrates a new cheap, privacy-oriented computer vision platform in action. OK, let's get this out the way up top: A robot doll that can sense your child's emotions and change how it behaves accordingly sounds like the kind of high-concept horror movie a Hollywood screenwriter would pitch after binge-watching Westworld and a Chucky marathon. In reality, it describes research being carried out by investigators at the University of Castilla-La Mancha in Ciudad Real, Spain. What they've built as a proof of concept is an artificially intelligent doll that can recognize eight different emotions and runs on an AI chip costing just 115 euros (around $130). Emotion recognition is carried out through facial-recognition technology, via a camera hidden in the doll's mouth.
