Abstract

Methods and technologies exist to capture a sharp digital reflection of a city and to track its evolution with a decreasing delay, but decision makers will not benefit from our ability to feel the pulse of a city unless we provide them with tools to visually perceive emerging patterns and observe their dynamics. This keynote reports on a two year long experience in feeling the pulse of Milan with CitySensing. This system–developed by Politecnico di Milano and Telecom Italia–allows fusing and visually making sense of social media streams and privacy-preserving aggregates of Call Data Records. The effectiveness of CitySensing was demonstrated during Milan Design Week 2013 and 2014 by realising a visual analytics dashboard for event managers and a public storytelling installation.

The Milan Design Week is a city-scale event held yearly in Milan. It features around 1,200 events in more than 500 places spread across the city and it attracts about half a million people from all over the world.

The vocabulary actually contains more terms, e.g., Grid and Cell, but in this short description we preferred a simplified description where the term Pixel is often used instead of Cell. We invite interested readers to check out [2] for more details.

Nowadays, this term is often used in the design of App interfaces, but the term roots back to user interface design in the late ’90s [12]. In this research, we adapt the methodology proposed in [12] to visual data analytics.
