Train stations are meant to be navigated efficiently. How easily recognizable spaces are within a station can help or hinder its navigability. To improve them, we first seek to understand how people perceive space.
Using computer vision, we map the distinctivness of Gare de Lyon and Gare Saint Lazare, train stations in Paris. We collected half a million geo-tagged 360° images and fed them through a model that told us how confident it was in identifying the space. For Gare Saint Lazare, humans validated the model's decision making.
Compare the decision-making of the model to humans for spaces inside Gare Saint Lazare.
Explore the images below and their corresponding spaces on the map to see how the model and humans differed in distinguishing the space. Participants pointed to the features in the images that most helped them determine the space. The resulting point image is converted into a heatmap to compare with the model's decision-making heatmap.
Test your ability to distinguish these spaces at SpaceMatch, a short image-based survey, and find out how you score.

An exploration of how digital technologies can enhance passenger experience.
This Senseable project, in collaboration with SNCF, shows changes in the perceptual shape of France based on how fast passengers can reach different parts of the country.
