The pilot version was done using about 5000 pictures for cities such as New York, Boston, Linz, Salzburg.


The interface is slightly different from the current version, and the question was also three kinds of "which one seems safe", "which one looks more upstream" or "which is more unique".


The color coding of the map for each question is as follows. Among New York, Manhattan seems to have the impression that it is safer, upper class, and unique than Queens.
