Body: <p>People could be sad, happy, depressive, angry, nervous, calm, relaxed, bored, etc. I don't know how to express all of these feelings and emotions in English terms (I'm not an English native speaker), which would enable me to search for research papers about this topic (e.g. in IEEE Xplore, Scopus, or ScienceDirect).</p>
  <p>So, is there any research on the identification/recognition of a person's feelings/emotions using facial expressions, heartbeat, body temperature, sweating, or nervous behavior (using one or all of them)?</p>

  Yes, there is research on this topic. The field that studies it is known as [**affective computing**](https://en.wikipedia.org/wiki/Affective_computing) (AC). [Emotion recognition](https://en.wikipedia.org/wiki/Emotion_recognition) seems to be a specific problem in affective computing, i.e. the recognition of emotions, while AC is also concerned with giving machines the ability to convey emotions (in fact, [this paper](https://www.sciencedirect.com/science/article/pii/S037872061500018X) differentiates the two). There's also [*sentiment analysis*](https://en.wikipedia.org/wiki/Sentiment_analysis), which refers to the analysis of the sentiment of people e.g. in social media (e.g. in comments) using natural language processing techniques, which doesn't seem exactly what you are looking for. These fields/tasks are all very related/similar, but I don't think they are exactly synonymous (although I'm not an expert in this topic).
