abstractions: abstracting a social system
The project began by considering the social system of deciding to sit or stand on the subway. A Cheerio system was devised to record and map that social system and was tested around a public park bench.
The analysis and results were then used to propose a social intervention in Sara D. Roosevelt Park using a series of canopies with musical instruments and a system of seats that were limited, forcing social interactions similar to the choice of sitting or standing on the subway.
