According to Nature, researchers from Vilnius Gediminas Technical University and Vilnius Municipality collected 879 million data points on depersonalized passersby’s emotional, affective, and physiological states between November 2017 and January 2023. Using sophisticated equipment including infrared cameras, facial expression analyzers, eye trackers, and heart rate monitors deployed across eight locations in Vilnius, the study developed the Multimodal Property Video Neuroanalytics (MOVE) system to analyze how human emotions correlate with property values. The research found that emotions significantly impact investment decisions, with models explaining up to 99.7% of variance in emotional states and revealing that a 1% decrease in average wind speed increases happiness by 0.09%. The study demonstrates that emotional data from random passersby can serve as a valid proxy for property valuation decisions. This groundbreaking research opens new possibilities for understanding the emotional economy of urban spaces.

The Science Behind Emotional Metrics
What makes this research particularly compelling is its methodological rigor in an area traditionally dominated by subjective assessments. The researchers employed multiple validation techniques including inter-rater reliability measures and sophisticated correlation analysis to ensure their findings weren’t statistical artifacts. The use of FaceReader software, which has been validated across thousands of studies, adds credibility to their emotional state measurements. More importantly, the scale of data collection—879 million data points over five years—provides statistical power that previous studies in this domain have lacked. This isn’t just tracking whether people smile in certain locations; it’s creating quantifiable emotional profiles of urban spaces with unprecedented precision.
The Ethical Implications of Emotional Surveillance
While the researchers emphasize that data was depersonalized, the study raises important questions about the boundaries of public surveillance. The equipment deployed—including electromagnetic respiration sensors and eye trackers—represents a significant advancement in our ability to monitor public emotional states without direct interaction. This creates a potential slippery slope where what begins as academic research could evolve into commercial emotional surveillance. The observer bias concerns mentioned in the study are just the tip of the iceberg when it comes to ethical considerations. As cities become smarter and more connected, we need clear frameworks governing how emotional data can be collected and used, particularly when it influences economic decisions like property valuations.
Market Implications for Real Estate
The practical applications for real estate investors and developers are substantial. The study’s finding that emotional states can explain differences in perceived rental value—such as the gym needing to increase from €84/m² to €139.43/m² to achieve optimal emotional valence—suggests a new dimension in property valuation. Traditional metrics like location, foot traffic, and demographic data now have an emotional counterpart. This could lead to the development of emotional premium pricing models where properties in emotionally positive environments command higher rents and sale prices. The involvement of Vilnius Gediminas Technical University lends academic credibility that could accelerate adoption by institutional investors seeking data-driven approaches to property valuation.
The Future of Urban Planning
This research represents a paradigm shift in how we think about urban design and development. The correlation between environmental factors like pollution levels, magnetic storms, and emotional states suggests that cities could be designed not just for functionality but for emotional well-being. The finding that weather patterns and pollution levels have measurable impacts on public emotions provides urban planners with new tools for creating happier, more productive urban environments. As cities compete for talent and investment, emotional analytics could become a key differentiator. The challenge will be balancing data-driven design with the organic, unpredictable nature of urban life that often creates the most memorable and valuable city experiences.
Methodological Considerations and Limitations
While the study’s scale is impressive, several methodological questions remain. The assumption of statistical independence between observations may not fully account for the complex social dynamics of urban environments. The research was conducted in a single European city with specific cultural and climatic characteristics, raising questions about generalizability across different geographic and cultural contexts. Additionally, the focus on passersby rather than actual tenants or buyers, while justified by the researchers, leaves room for further validation. Future research should explore whether emotional states of temporary passersby truly correlate with the decision-making processes of long-term property occupants.
The Road Ahead for Emotional Analytics
The successful application of this methodology suggests we’re at the beginning of a new era in urban analytics. As sensor technology becomes more sophisticated and AI analysis more refined, we can expect emotional metrics to become standard in real estate development and urban planning. The next frontier will likely involve real-time emotional mapping of cities, allowing for dynamic responses to emotional trends. However, the commercial application of these technologies must be accompanied by robust ethical frameworks and transparent data practices. The value of understanding urban emotions is clear, but preserving public trust and privacy will be essential for this field to reach its full potential.
