Thought-detection: AI has infiltrated our last bastion of privacy

Our thoughts are private – or at least they were. New breakthroughs in neuroscience and artificial intelligence are changing that assumption, while at the same time inviting new questions around ethics, privacy, and the horizons of brain/computer interaction. Research published last week from Queen Mary University in London describes an application of a deep neural network that can determine a person's emotional state by analyzing wireless signals that are used like radar. In this research, participants in the study watched a video while radio signals were sent towards them and measured when they bounced back. Analysis of body movements revealed "hidden" information about an individual's heart and breathing rates.
