While working on research for one of my classes for my Master's, I came across this article. It lists 10 examples of body language the author uses to assess the feelings of his program users. As I was reading the list, I realized these are many of the examples of body language I use to assess how students are doing with new content/knowledge. You can check out the article here: Full article
Or read the list I am referencing below:
1. Frowning. If a user is frowning, it can be a sign of a necessity to concentrate, displeasure, or of perceived lack of clarity
2. Brow Raising. When users raise their brows, it can be a sign of uncertainty, disbelief, surprise, and exasperation. While surprise isn’t always negative, we don’t necessarily want our users to be surprised or uncertain of the experience on our platform
3. Gazing Away. When a user gazes away from the screen, they may feel deceived, ashamed, or confused. They could also very possibly be bored with what is on the screen in front of them
4. Smiling. A smile is a sign of satisfaction in which the user may have encountered something satisfying or joyful
5. Compressing the Lip. Seeing a user compress their lips is a sign of frustration and confusion. I see this a lot when a user intends to do something, but it does not work, causing frustration and anxiety
6. Moving the Mouth. If the user is speaking to themselves, trying to understand or complete a task, this indicates them feeling confused or lost in the experience
7. Expressing Vocally. Vocal expressions such as sighs, gasps, coughs, as well as the volume of the expression, the tone or quality of the expression may be signs of frustration or deception.
8. Hand Touching the Face. If a user is touching their face during the interview, they could be tired, lost, or confused. This can also indicate a high level of concentration and frustration with a task.
9. Leaning Back on the Chair. When a user (or anyone, really) leans back in a chair, it is an indication they are having a negative emotion and would like to remove themselves from the situation. This generally shows a fairly high level of frustration
10. Forward Leaning the Trunk. Leaning forward and showing a sunken chest may be a sign of difficulty and frustration with the task at hand. At this point, the user may be close to giving up on a task or experience.
