AI That Understands Your Body Language


Ubiquitous sensing, paired with machine learning, can amalgamate all of the signals we give off--from the timbre of our voice to the dilation of our pupils--to detect signs of conditions, such as Alzheimer's disease, years before a traditional diagnosis. Emerging "empathetic technology" sounds a bit scary to people who don't like the idea of machines reading our feelings. We want to think we can mask how we're feeling by controlling our faces, voices, and body language--and we don't entirely trust what machines do with this data. True, this is a thorny topic. But the potential for empathetic technology to improve our health and lives makes dealing with the uncomfortable questions worthwhile.
