Our emotions profoundly shape our actions and outcomes. This fundamental aspect of human nature supports the rapidly evolving field of emotional AI, sometimes called affective computing or artificial emotional intelligence, where advanced computation meets human psychology.
In this dynamic field, there’s a clear emphasis on deciphering and addressing human emotions, leading to a profound transformation in human-machine interaction.
As we witness the increasing integration of AI into our daily lives, the development of emotionally intelligent machines becomes a crucial step towards a future where machines not only follow our commands but also understand our feelings.
Now, let’s explore how artificial intelligence uses human emotions in this changing dynamic.
What is Emotional AI?
Emotional AI, sometimes called emotion AI, focuses on machines and systems recognizing, understanding, and reacting to human emotions. This enhances human-machine interactions and fosters natural and intuitive communication.
Emotional AI blends various scientific fields, including computer science, psychology, cognitive science, and linguistics. This interdisciplinary approach helps machines better grasp and respond to human emotions.
These AI systems work together to understand emotions by analyzing facial expressions, vocal cues, and physiological signals, allowing them to estimate a person’s emotional state.
How Does Emotional AI Work?
Emotional AI, similar to conversational AI chatbots that leverage large language models (LLMs) for generating responses, also relies on extensive datasets. However, the difference lies in the nature of the data it employs.
To better understand how emotional AI works, let’s look into its inner workings:
1. Data Collection
In the initial stage, emotional AI models collect data from a multitude of sources, covering not only text but also various other forms:
- Voice data: This can originate from recorded customer service calls, videos, and other similar sources.
- Facial expressions: Obtained through methods like capturing expressions using phone video recordings.
- Physiological data: Metrics like heart rate and body temperature are measured to assess the emotional state.
It’s important to note that the type of data used by emotional AI models may vary depending on their specific applications. For instance, a call center may not require visual or physiological data, unlike healthcare scenarios where such data proves highly valuable.
2. Emotional Recognition
The approach to understanding emotional states depends on the type of data:
- Text analysis: Techniques like sentiment analysis and NLP interpret written text, identifying keywords, phrases, or patterns indicative of emotional states.
- Voice analysis: Machine learning algorithms analyze voice characteristics such as volume, pitch, tone, and speed to infer emotional states.
- Facial expression analysis: Computer vision and deep learning methods analyze facial expressions, recognizing both basic emotions (happiness, surprise, anger, sadness, etc.) and subtle “micro-expressions.”
- Physiological analysis: Some emotional AI systems analyze physiological data to determine emotional states, typically used in research or healthcare with specialized sensors.
The specific functioning of emotional AI varies based on its intended application, but most models employ at least one of the mentioned techniques.
3. Generating Responses
In the final step, the AI model responds in a manner appropriate to the determined emotional state. The nature of this response depends on the AI’s purpose, which could involve alerting a call center agent to an upset caller or personalizing app content.
The potential applications of emotional AI are vast, and organizations are already finding diverse uses.

Emotional AI in Education
Emotional AI initially found its place in education by assisting children with special needs. However, today, there’s a growing interest in integrating affective computing into various educational scenarios.
For instance, Entropik, a human insights company from India, relies on eye tracking and facial coding algorithms, analyzing emotional triggers and user journeys.
During student sessions, it records and processes data through the eye-tracking API, producing critical metrics for engagement, attention, and fatigue for both students and tutors.
These metrics are invaluable tools for the tutoring platform, pinpointing content improvement areas and enabling proactive measures to boost student engagement and attention span, ultimately elevating the quality of education.
Emotional AI in the Automotive Industry
In the automotive industry, ongoing research explores emotional AI’s potential in driving assistance. It acknowledges that despite the emphasis on safety outside the vehicle, internal distractions can also jeopardize safety.
Imagine a car equipped to detect a driver’s heightened blood pressure during an argument with a passenger and adjust the speed accordingly. Picture a sensor that subtly guides the steering wheel to center the car in the lane when a sleep-deprived driver unknowingly veers towards the curb.
For instance, Affectiva’s emotional AI technology is making significant strides in this area. Their AI has the capability to identify a driver’s emotional state by analyzing facial expressions and voice, contributing to safety by alerting drivers when they may be distracted or drowsy.
Affectiva’s automotive AI service goes beyond this; it monitors the driver’s state and the occupants’ experiences to enhance road safety and overall satisfaction.
