Familiar Strangers  Urban Infrastructural Responsive Installation

Interactive digital media transforms overlooked underpass into a "space for conversation."


Like many underpasses or underused public spaces, the existing condition deters usage, and lack of usage sometimes makes these spaces harder to salvage. The Calgary underpass was one that needed TLC.

When surveying the communities, users of the space commented that the underpass was unusable. It was an "old, deteriorated" place that "needed attention." In its current state, pedestrians felt "stuck once you enter," and felt it was unsafe to walk there at night.

How do we integrate urban design strategy and public art to revitalize urban infrastructure and transform it into a welcoming and safe public space for pedestrians and local residents?

Can technology embedded spaces help cities be more intuned with their residents?

Technology Embedded Cities

A custom detection technology software was developed by INVIVIA that analyzes and creates an abstract representation of pedestrian movements, encouraging interaction among the ‘familiar strangers’ that the daily commuters pass by everyday.


Citizen Interactions 

This media-integrated underpass is designed to encourage a new experience of urban social interaction. It allows passerbyers  to see with clarity the manner and rhythm of their own walk, moving in the opposite direction as if their reflection were a passerby - an another urban stranger.
