Zusammenfassung
Pokémon Go has received unprecedented media coverage for a location-based
game that uses augmented reality techniques. The game has been commonly
associated with greater access to public spaces, increasing the number of
people out on the streets, and generally improving health, social, and security
indices. However, the true impact of Pokémon Go on people's mobility patterns
in a city is still largely unknown. In this paper we perform a natural
experiment using data from mobile networks to evaluate the effect of Pokémon
Go on the pulse of a big city: Santiago of Chile. We found a significant effect
of Pokémon Go on the floating population of Santiago: up to 13.8\% more
people being outside at certain times, even if they do not seem to go out of
their usual way. These effects at specific times were found by performing
several regressions using count models over snapshots of the cell phone
network. The effect is significant after controlling for land use, daily
patterns, and points of interest in the city. Particularly, we found that, in
business days, there is more people on the street at commuting times, meaning
that people did not change their daily routines but slightly adapted them to
play the game. Conversely, on Saturday and Sunday night, people indeed went out
to play to places nearby their homes. Even if the statistical effects of the
game do not reflect the massive reach portrayed by the media, it still allowed
the streets to become a new place for people to spend time in. This is
important, because results like these are expected to inform long-term
infrastructure investments by city officials, jointly with public policies
aimed at, for example, stimulating pedestrian traffic or suggesting alternative
routes. Our work supports the notion that location-based games like Pokémon
Go have benefits for the life in the city.
