Emotion AI or affective computing is a subset of artificial
intelligence (AI) that measures, understands, simulates, and
reacts to human emotions. It is also known as artificial emotional
intelligence.
Machines can analyze large amounts of data, such as voice inflections and facial expressions, to recognize when those inflections correlate with stress or anger. For example, natural language processing tools can be used to analyze social media posts and infer how happy or sad a person is feeling at any given time. Over time, this algorithm can even produce a video out of a person’s emotional ups and downs.
