Attention & Emotions - measured online

Have you heard about algorithms that can automatically recognize emotions just by measuring facial expressions? This tool, called face coding, is becoming popular because of its ability to expand our understanding of emotions, based on people’s facial expressions. By tracking facial expressions in real-time, researchers can capture moments of engagement, joy, or even frustration. Fascinating!

What is Facial Coding?

Facial coding is a process that quantifies emotional responses to digital content. It's deeply rooted in Paul Ekman's research, uses software and webcam capture to interpret complex human emotions through facial expressions. Dr. Ekman's research has identified six basic emotional expressions that are universally recognized across cultures. 

These expressions are: 

• Anger, 
• Happiness, 
• Surprise, 
• Disgust, 
• Sadness
• Fear,

And they are distinguished by different facial muscle movements. This highlights the universality of emotions through facial expressions, making facial coding technology an important tool in market research all over the world.

In 1978, Ekman and Friesen released the Facial Action Coding System (FACS), which maps the movements of facial muscles. Facial Action Coding System decays the facial behavior into 46 so-called action units. What are precisely action units? As we wrote in previous article „They are defined as contractions or relaxations of one or more facial muscles. The FACS manual has over 500 pages and describes all action units along with their meaning according to Ekman’s interpretation”.

The Facial Action Coding System has changed how emotional responses are interpreted. This approach has improved the accuracy of facial coding, making it a great technique for ad and video testing among research and advertisement agencies. By tapping into consumers' emotional responses, researchers can gain deeper insights into how people react to stimuli. This, in turn, enables companies and agencies to create more effective marketing campaigns and products that resonate with their target audience.

How Facial Coding Technology Works

The science behind facial coding is relatively simple. It records facial expressions via webcam and analyzes them using facial coding software.

The process of face coding typically involves these steps:

1. Stimulus presentation: Participants are exposed to stimuli, such as an advertisement, product, or experience.
2. Facial expression and emotions recording: The participant's facial expressions are recorded using a camera or webcam that track tiny movements of facial muscles. With RealEye, this can be done remotely using the participant's own device, so you don't need any extra equipment.
3. Facial coding analysis: Now, the software analyzes the recorded facial expressions frame by frame to identify specific emotions and movements of facial muscles. This process is known as coding. The algorithm seeks to determine the emotional responses' type, intensity, and duration.
4. Interpretation and reporting: The results of the face coding analysis are interpreted to deliver insights into the participant's emotional reactions. 

Face coding is often used with other research methods, such as surveys or eye-tracking. It provides insights into user experience, marketing, and product development strategies.

In What Types of Research Facial Coding is Used?

Facial coding has revolutionized the way we understand basic emotions. This amazing research tool can be used in many industries. 

Automated facial coding is very popular in marketing and consumer research. Marketers love face coding! They use trackers like RealEye to measure emotional responses to their campaigns. This research technique provides moment-by-moment emotional and cognitive metrics, allowing for optimized marketing strategies and more effective ad campaigns.

Facial coding can also help with your market research. One effective way to gather insights into customers' feelings about your products is to conduct market research using face coding. This can help you find areas for improvement and make adjustments before your products hit the store shelves. You can also proactively handle any negative feedback that may come your way.

Is Face Coding the Same Thing as Face Recognition?

That’s a great question! If you need a TLDR type of answer, it’s a short: no. The terms „face coding” and „face recognition” are related concepts but serve different purposes. 

The coding process typically doesn't involve identifying specific individuals but focuses on interpreting basic emotions and reactions based on facial expressions. It also utilizes the previously mentioned Facial Action Coding System (FACS) to categorize and analyze facial movements.

Face recognition, on the other hand, was created to verify individuals' identities based on their facial features. It's a process that involves comparing a person's face with a database of known faces to see if there's a match. It has applications, e.g., in security systems, access control, law enforcement, and digital authentication.

What Are The Pros of Facial Coding?

You already know a lot about face coding and its use on the market. What are the top strengths of this tool?

• Facial coding integrates data from eye-tracking, emotion recognition, and declarative surveys in just one tool.
• It’s easy to use. Participants take the test in the comfort of their own homes, so they get to experience a natural, non-corrupted laboratory environment. This allows them to fully concentrate and perform to the best results.
• In order to compare how different target groups perceive an ad, you can easily filter the answers. For example, you can filter by gender or age, or you can create your own tags to filter results by survey answers.
• Sometimes, participants may not realize that they liked a piece of content or may not have wanted to admit that they liked it. This type of study helps us understand the actual behavior of participants rather than just their verbal responses.
• Before launching your ad campaign, you can allocate a higher budget to ads with the highest score and save some money.
• You receive the results immediately after the study.

The Future of Facial Coding

It's exciting to see how facial coding changes how technology interacts with human emotions.

Emotion AI Integration: In 2018, Gartner's Top Predictions Report predicted that by 2022, 10% of devices would possess emotion AI capabilities. In 2019, Gartner further predicted that by 2024, AI's ability to identify emotions would seriously impact over half of the online advertisements users experience.

Transformational Impact: When used ethically, facial coding possesses the remarkable ability to improve consumer interactions, redefine entire industries, and positively impact people's lives. 

Ethical Issue: As more companies use facial coding, it's important to manage issues around privacy and consent. Responsible implementation and transparency are essential for the benefit of everyone involved. 

The world is in a constant change, and technology never stops to amaze us. To keep up with the competition, it is wise to use the latest tools and metrics that the market offers. Facial coding can help businesses recognize emotions, but many are unaware of its importance.
