AI and The Science of Facial Emotion Recognition

A simple expression may convey all you mean. One's face is a window into one's thoughts. We can't help but use it as a fundamental means of communicating our feelings and goals with others around us.

Machinery to comprehend and imitate human behavior to serve humans better. TeachingArtificial Intelligence (AI) to understand emotions can elevate human-machine interactions to a whole new level, as robots learn our habits and routines.

Facial Emotion Recognition (FER) is a technology that analyzes facial expressions from both static photos and videos to determine an individual's emotional state. 

How AI Is Revolutionizing Facial Emotion Recognition (FER)

Facial recognition technology has grown deeply integrated into our day-to-day lives, allowing us to do anything from unlocking our phones to get access to sensitive data stored on our computers. Recently, there has been much discussion over technology's use to recognize emotions via facial expressions. When combined with Machine Learning (ML) and Deep Learning, AI is creating software for recognizing facial expressions of emotion. This software will revolutionize various sectors in terms of increased convenience, safety, and the efficacy of AI-based outputs.

 So, how can facial emotion recognition software be used?

Facial Emotion Recognition (FER) Applications

The potential applications of FER span a wide variety of fields; some of these applications are shown here, organized according to the category in which they fall.

Education

The pandemic has made homeschooling a necessity. Virtual learning has observable benefits, but the sector must also cope with its downsides. Learning systems driven by AI can analyze muscle points on students' faces and recognize emotions such as pleasure, sorrow, aggression, and surprise. This can support teachers in understanding a student's grasping ability and designing appropriate teaching.

 In addition to targeting knowledge gaps, the application offers game-like assessments to make learning enjoyable depending on the user's emotional landscape. Artificial intelligence can make the virtual classroom at least as good as the real thing.

In the learning sector, facial emotion detection software can also be helpful to:

●  Identify students' emotional reactions to an educational program and modify the learning process.

●  Create an effective tutoring system

●  Identify online learning participation.

Safety and Security

Facial emotion detection technology can be used by airport security, border control, and police officers to detect possible threats and highlight faces that reflect dishonesty or fear.

In smart automobiles, facial expression recognition can inform the driver of their tiredness, minimizing accidents by a considerable amount.

For public safety, facial emotion recognition software can also be used to: 

●  Lie detector tests and high-tech checkpoints at the border 

●  Predictive scanning of public settings to detect feelings that may pose a terrorist danger

●  Reviewing crime scene footage

Healthcare

Medical workers who work with patients who have difficulty expressing themselves via more conventional channels can find that facial emotion recognition technology is helpful. Because of this, medical professionals can provide superior care to their patients.

In the medical sector, facial emotion recognition can also be beneficial to: 

●  Find out whether someone has autism.

●  To help those who may be suffering from psychosis or depression.

●  Preventing suicide

●  Recognize signs of depression in the elderly

Hiring and HR processes

Several spheres of evaluation and subjectivity can be applied to an interview between an applicant and an interviewer. Because of this subjectivity, it can be challenging to evaluate a candidate's potential for success on the job based on their personality alone. Since there are so many layers of linguistic interpretation, cognitive biases, and context between us and the candidate's true meaning, we can't control the outcome. Here, AI comes into play since it can analyze a candidate's facial expressions to determine how they are feeling and what attributes their personality displays. 

For employment, facial emotion recognition software can also be used to: 

• Assist recruiters in making decisions

• Detect indifferent job applicants during an interview

• Check staff attitudes and concentration

How Facial Emotion Recognition Works

 Since it is a computer-based technology, a facial expression recognition system employs algorithms to detect faces, code facial expressions quickly, and identify emotional states. It utilizes the built-in or external cameras of laptops, mobile phones, digital signage systems, or computers to analyze facial features in still photos or videos. Science acknowledges seven primary feelings: joy, sorrow, surprise, anger, fear, disgust, and contempt. Computer-assisted camera analysis often uses three stages to interpret a person's facial or emotional state.

● Detecting faces

Face detection is the search for human faces in a picture or live video. 

●  Identifying features of the face

The process of gleaning facial data from identified faces. The human face is seen as an inanimate object by the computer, which analyzes its many features like eyebrows, eyes, and lips in terms of their location and tracks their motions. Two examples are identifying facial features' shapes and analyzing the skin's texture. 

●  Understanding and categorizing facial expressions and emotions

Interpreting the meaning of a person's facial expressions by analyzing the way their features move and change in appearance and placing that data into categories such as facial muscle activations (like a smile or frown), emotions (like joy or anger), and attitudes (like (dis)liking or ambivalence). The system then attempts to match the observed facial expression to one of its stored emotional states. 

It's been determined that there is an AU for every feeling (AU). It indicates how our faces move in response to various emotional states is highly correlated.

Accurateemotion identification is an understanding of both artificial intelligence and psychology.

To Sum Up

Even though there are challenges with facial emotion recognition technology, it is a growing industry worth billions of dollars. The only way to know what will happen with this technology is to wait and see. Although facial emotion detection using artificial technology is still difficult, recent machine learning algorithms have demonstrated encouraging results.
