Facial Coding

Facial Coding Technology

Facial coding is a technique that measures human emotions by analyzing facial expressions. It is based on the idea that some facial expressions are universal and reflect basic emotions, such as happiness, surprise, anger, sadness, engagement, disinterest and more. Facial coding uses computer algorithms to detect and classify facial movements, called action units, that correspond to different emotions.

Facial Coding: Introduction

Facial Coding AI, also known as facial expression analysis, is a technology that uses artificial intelligence to interpret and analyze human emotions through facial expressions. It achieves this through computer vision and machine learning techniques that recognize and categorize specific facial movements and expressions into different emotions.

"Facial coding is a method of measuring and analyzing the micro-expressions and subtle movements of the face to understand and interpret human emotions and behavior. By capturing and decoding the unconscious and often fleeting signals that the face sends, we can gain a deeper understanding of what people are truly feeling and thinking, and how they respond to various stimuli in their environment." - Paul Ekman, psychologist and Pioneer in the field of facial coding and emotions.

Don’t make it complicated!

Think of Facial Coding AI as a digital translator where you can read facial cues and translate them into emotions like happiness, sadness, or surprise. It can do this by detecting small changes in your facial features, like the way your eyebrows move or your lips curve.

How Facial Coding AI Works?

The science behind this is quite simple; it works by capturing facial expressions & movements of facial muscles. The process is based on Paul Ekman's FACS (Facial Action Coding System), which describes all visually discernible facial movements and breaks down facial expressions into individual components of muscle movement referred to as Action Units (AUs).

According to Amy Cuddy, social psychologist, and expert in body language.
“FACS is a groundbreaking tool for decoding emotions and improving our understanding of human behavior. It has the potential to revolutionize the way we interact with each other and the world around us."

By leveraging FACS, you can operate Facial coding in three stages for a comprehensive human emotion analysis.

  • Image Acquisition: In this stage, you will capture the image through various sources such as webcams, USB cameras, or CCTV cameras.
  • Facial Landmark Detection: The next step involves the detection of facial landmarks, including eyes, eye corners, brows, mouth corners, and nose tips. Advanced algorithms can detect these landmarks and create a simplified face model, which accurately reflects the actual face but only includes the features necessary for coding.
  • Coding and Insight Extraction: The final stage of the process involves the application of machine learning algorithms to analyze facial landmarks. These algorithms translate the landmarks into Action Unit codes, which are then statistically interpreted to yield metrics for facial expressions. The combination of Action Units provides a comprehensive analysis of the emotions displayed on the face.

Why Do You Need Facial Coding?

Facial Coding Helps in Data-Driven Decision-Making Process
Facial coding helps researchers, marketers, and anyone looking to gain insights into how people are feeling to make decisions. It provides a quick and easy way to turn a person's facial expressions into quantifiable data, which you can use to gain a deeper understanding of their emotions.

For example, a retailer might want to know if a new store design will be well-received by shoppers. Now, by showing the designs to shoppers and recording their reactions, the retailer can use Facial Coding AI to quickly determine which designs are likely to be popular and which ones are likely to be met with negative reactions.

Facial Coding Has Practical Applications
One example is Mars, a confectionery and pet food company, that employs facial coding in market research. They utilize this technology to assess emotional reactions to their ads, such as the "Snickers" and "M&M's" campaigns and identify the most effective and resonant elements. By examining viewers' facial expressions, Mars can adjust its advertising strategies to increase engagement. Furthermore, Mars applies facial coding to evaluate product packaging designs and collect data on consumer preferences.

Facial Coding Generates Accurate Insights
According to the Greenbook studies, facial coding can identify all emotions with an accuracy rate of over 90%. This implies that facial coding can offer better insights than traditional research methods like surveys or interviews that rely on self-reporting, which may not fully capture people's emotions. By precisely detecting and analyzing facial expressions, facial coding can provide a more accurate understanding of people's emotions and attitudes towards products, services, or messaging objectively.

Compliances and ethics of facial coding

Compliance and ethics play a crucial role in facial coding, which involves gathering and evaluating individuals' facial expressions to determine their emotions and attitudes.

“Facial coding studies must be conducted in a way that ensures the safety and well-being of research participants, and that respects their privacy and dignity." - World Association for Public Opinion Research (WAPOR)

From a compliance standpoint, it is vital to ensure that the collected data through facial coding is obtained lawfully and ethically, with participants providing informed consent. This may include obtaining consent, safeguarding the data from unauthorized access through secure storage, and adhering to privacy regulations such as the GDPR in the EU.

From an ethical standpoint, it's essential to consider the potential impact of using facial coding and to ensure its responsible and non-discriminatory use. For instance, you should not make significant decisions affecting individuals, such as employment or promotion, without additional validation and transparency about its usage and utilize the technology in a way that may perpetuate bias or reinforce stereotypes.

Future of facial coding

According to Forbes, "Facial coding technology is advancing rapidly and will play an increasingly important role in the fields of market research, psychology, and human-computer interaction in the future."

The future of facial coding AI looks promising as it projects to grow at a compound annual growth rate (CAGR) of around 20% between 2022 and 2027, driven by the increasing demand for more accurate and sophisticated methods of measuring and understanding human emotions and behavior.

This growth is further bolstered by the increasing interest in using facial coding technology in fields such as artificial intelligence, virtual reality, and human-computer interaction, with researchers and developers working on creating new and innovative applications that will enable us to better understand and interact with our digital devices and environments. However, there are also concerns around privacy and ethics to be addressed as the technology continues to develop. Despite these concerns, the future of facial coding appears promising and probably grow.
