Edo: A Participatory Data Physicalization on the Climate Impact of Dietary Choices

People

Abstract

A participatory data physicalization, or PDP, is a physical visualization that allows people to physically participate in the creation of the visualization, by directly encoding their data. PDPs offer a way to engage a community with data of personal relevance that otherwise would be intangible. However, their design space has only begun to be explored, and most prior work shows relatively simple encoding rules. Therefore, we present a design exploration of different ways of faceting contributed data: by week, day, or person. Specifically, we designed Edo, a PDP that allows a small community to contribute their data to a physical visualization showing the climate impact of their dietary choices. In this pictorial, we elaborate on the design process of Edo and reflect on the findings of a three-week deployment of different layouts of Edo.

Figures

A poster explaining the encoding used in Edo and showing a size comparison in the top right corner to illustrate one's total carbon budget for a 5-day work week, assuming one aims for no more than 2 tons CO2eq per year.

We explored three different layouts. Shown here is the third one which has one budget circle per person and which shows underneath the main circle how many meals were added (note that some people got sick that week and didn't fill in data for all their lunches). See the paper for more details on the other two layouts.
