Use emotion recognition (Sightcorp)

When to use this

Use emotion recognition to analyze the emotional state of faces detected by the DeepSight Toolkit. This feature detects seven emotions and helps you understand customer engagement and sentiment in your physical spaces.

Steps

1. Ensure you are running DeepSight Toolkit 7.0 or later.
2. Enable the Sightcorp emotion recognition feature in your Displai settings.
3. View emotion scores for each detected face. The system reports seven emotions: neutral, anger, disgust, fear, happiness, sadness, and surprise.
4. Each emotion receives a score between 0 and 1, and all seven scores always add up to 1.0 at any point in time.

Verify

Check that emotion scores appear in your analytics dashboard. Verify that all seven emotion scores for a given face sum to 1.0.

Interpreting emotion scores

Report the dominant emotion

Report the highest average emotion score as the dominant emotion only if that average exceeds 0.5. For example:

• neutral = 0.0 (avg)
• anger = 0.1 (avg)
• disgust = 0.1 (avg)
• fear = 0.1 (avg)
• happiness = 0.5 (avg)
• sadness = 0.1 (avg)
• surprise = 0.1 (avg)

In this case, report the person as “happy” because happiness = 0.5.

Handle ambiguous results

If all scores are low or too close to each other, categorize the person as “neutral”. For example:

• neutral = 0.2 (avg)
• anger = 0.1 (avg)
• disgust = 0.1 (avg)
• fear = 0.1 (avg)
• happiness = 0.2 (avg)
• sadness = 0.2 (avg)
• surprise = 0.1 (avg)

Report the dominant emotion as “none (neutral)” because no single emotion clearly dominates.

Accuracy considerations

Head pose and lighting affect emotion detection accuracy. For best results:

• Only use emotion estimations for faces detected within ±15 degrees of pitch and yaw (frontal faces).
• Exclude faces with extreme angles or poor lighting from emotion analysis.

If it doesn’t work

• Emotion scores seem inaccurate: Verify that faces are within ±15 degrees pitch and yaw. Check lighting conditions in your space.
• No emotion data appears: Confirm DeepSight Toolkit version is 7.0 or later and that Sightcorp integration is enabled.
• Privacy or compliance concerns: Contact support to discuss emotion recognition data handling and retention policies.
