Each visualization has a similar foundation which portrays passive data (i.e., background information gathered by the phone’s sensors). This information includes: localization, weather, noise, steps, photos, battery and internet connection.
So, by comparison methods, when we analyse someone else’s artwork, we are able to understand that the person in question walked more or less in a certain day of the month, or that a certain day was colder or warmer than other, for example.
The visualizations become more complex and personal as the active data is mapped, i.e., non-standard data, gathered through questions. This questions are set by the user and are asked several times a day — e.g. “how many coffees did you drink today?”, “who are you with right now?”.
All this information is represented through a system of symbols. Each type of possible answer (token, yes/no, multiple choice, person or number) has a specific graphic representation.
Thanks to the combination of standard and non-standard data, it is easy to recognize when 2 different artworks belong to 2 different people.
The following pictures show 4 different artworks from 4 different people.
