Perceptual Maps: Mapping the visual perception oftravelers in a city using google street view as sensor Keywords: Psychogeography, computer vision, Art, Flaneur/Baudelaire Each geotagged panoramic image = visual sensor of the area What if I use every google street images of a city (e.g. Paris) and analyze specific visual perception/feature to create perceptual maps?
Example: Claustrophobia Map - sensing the“openness” of urban spaces.Question: Where are the most open spaces in Paris? how much sky can I perceive if I travel there? People perception angle when traveling
Mapping the perceptionEach colored point on the maprepresents the degree of “openness” ofan area (computed for each associatedgoogle street view image) Dark area = Average openness= Orange/Red point (yellow point)

Level of green perception inthe network of Paris(Perceptual GPS: I want a “green” travel,guide me using such a map!)
unachieved personal research projectTODO• Exploring other visual features (e.g. mapping the “colourfulness” of an area), detecting specific textures (e.g. mapping architectural styles in a city)• Perceptual GPS: programming travels in a city according to visual perceptions (see also “random GPS” /“serendipity in a physical network” project)---- What is the goal of such kind of maps?”- just the pleasure to explore new maps: mapping the visual perception of travelers in a city. (not enough time to explore fully the concept)Contact: firstname.lastname@example.org (nicolas maisonneuve)
