FoodMood [foodmood.in] by Affect Lab, Ai Applied and Jana + Koos aims to communicate a better understanding of global food consumption patterns and their impact on the daily emotional well-being of people.

The treemap captures, in real-time, the foods that people are tweeting about (in English) and how they feel about them. Each recognized food item is represented by a rectangle, of which the size corresponds to the number of times that food has been mentioned, and the colors stand for a range of positive to negative sentiments. More detailed information is provided, such as a country's GDP statistics and obesity levels.

Users can compare an arbitrary number of countries against each other, and filter the data by time, by country or by popularity.

More detailed information about this project has been published as an academic publication (PDF).
