Real-time sentiment analysis. Understand how your audience responds to your content, topics and products.
With AI‑powered video analytics, knw. measures the emotions, attention, and engagement of your attendees - fully anonymized, GDPR‑compliant, and in real time. For the first time, you gain a clear understanding of which content actually resonates and why.
What Is Sentiment Analysis?
The sentiment analysis provided by knw. delivers precise, data‑driven insights into your audience’s interest, attention, and emotional engagement.
This is made possible through advanced camera technology, AI‑driven image analysis, and proprietary algorithms that process all information in a fully anonymized way.
This gives you, for the first time, objective and reliable data on which topics, content, or product features truly capture your audience’s interest - from emotional responses to changes in attention over time, all the way to engagement and activation levels.
You also receive detailed sentiment scores for individual speakers, sessions, or the entire event, making intuitive impressions finally measurable.
What You Achieve With Sentiment Analysis
Objective product feedback: Identify which products or product groups generate the highest customer interest - even down to individual product features.
Better content & messaging: Validate your themes and communication strategies based on real audience reactions.
Higher attendee engagement: Use real‑time data to dynamically adjust your content and enhance the overall experience.
Maximum relevance: Identify top performers across topics, speakers, presentations, or exhibits.
Strategic optimization: Make decisions that are data‑driven, evidence‑based, and proven to be effective.
How the Technology Works
Video frames from cameras are processed in real time and instantly transformed into fully anonymized datasets.
The raw image is never stored at any point.
The AI‑powered knw. algorithms then analyze the contextual correlations - second by second..
They detect how many people are present, assign age and gender only in aggregated form, and measure two key sentiment parameters: Experience, the overall positivity of audience perception, and Emotional Activation, which reflects how intensely the audience responds emotionally.
Data processing is fully GDPR‑compliant - without exception.
No personal data is ever captured, as each camera frame is immediately overwritten.
All generated datasets are stored exclusively in a certified EU‑based cloud, where they are securely and anonymously processed.
