Every decision a person makes, what to buy, where to linger, and when to leave, is influenced by emotion. But in physical spaces, those emotional signals often go unnoticed or unmeasured.
Facial emotion recognition software changes that. It gives brands a way to read and respond to human reactions in real time, quiet moments of interest, frustration, delight, or hesitation. In fact, studies show that 70% of consumers who experience a strong emotional reaction to a brand’s messaging are much more likely to buy
At Displai, we help brands turn those insights into action. With Displai’s Visitor InSights emotion recognition technology, you can understand how people feel in your stores, hotels, and venues, and use that knowledge to shape better experiences, smarter signage, and more meaningful engagement.

What Is Emotion Recognition Software?
Emotion recognition software uses Visitors Insights to detect and interpret human emotions by analyzing facial expressions in real time. These tools don’t just see a face; they recognize patterns, movements, and micro-expressions that reflect emotional states.
At its core, this technology captures non-verbal reactions and classifies them into universal emotions like joy, surprise, or frustration. It works through a combination of facial detection, landmark mapping, and deep learning algorithms that translate facial data into emotional insight.
Unlike research-heavy tools, emotion recognition software solutions like Displai’s are designed for physical environments. They deliver fast, anonymous insights that integrate directly with digital signage, CRM, and in-store dashboards. The result: real-time emotional intelligence, no added complexity.
How Facial Emotion Recognition Software Identifies Emotions
Every emotion leaves a trace, a subtle lift of the eyebrow, a tightened jaw, or a wrinkled nose. Facial emotion recognition software captures those signals and uses machine learning to map them to one of seven universal emotions.
These seven emotions, identified by psychologist Paul Ekman, form the foundation of most modern facial expression analysis software:
- Happiness: Raised cheeks, crow’s feet, smiling mouth
- Surprise: Wide eyes, lifted eyebrows, open jaw
- Anger: Furrowed brows, tight lips, intense eye contact
- Fear: Tense eyelids, horizontal mouth stretch, wide eyes
- Sadness: Drooping mouth, arched inner brows, downcast eyes
- Disgust: Nose wrinkle, upper lip raised
- Contempt: Half-smile or one-sided lip raise
To identify these accurately, the software performs three key steps:
1. Detects facial landmarks – Tracks eyes, eyebrows, mouth, nose, and jawline in real time.
2. Measures micro-movements – Analyzes changes in muscle tension, angles, and symmetry.
3. Assigns a confidence score – Each emotion is matched with a real-time probability score, offering clear, actionable insights instead of guesswork.
When built into emotion recognition software solutions like Displai’s, this process happens in milliseconds, with results flowing directly into your signage strategy, testing process, or customer experience dashboard.
