Before computers were digital, they were people who performed calculations by hand for scientific research. Starting as a cottage industry, this practice continued into the 1950s, even as human computers were replaced by the machines we use today. Human Computers is a long-duration performance where thirteen performers calculate by hand over a period of eight hours something trivially easy for the computer to do: decode a single image PNG file. Inspired by historical examples as well as office culture and the automation of labor, this performance is the physical enacting of a technology that is pervasive and difficult to understand.
Performers sit at custom furniture and slowly decode the file (printed as spiral-bound books) using paper worksheets; resulting pixels are assembled from CMYK transparencies, stapled to worksheets, and hung. The image (a screenshot from Google Streetview of the street outside the gallery) is resolved over approximately eight hours: office meets regimented dance. This project reveals the histories/affordances that a single file format encapsulates and suggests that slowness and collaboration can be a form of knowledge-production.
This project also included a limited-edition flowchart poster, showing the decoding process used in the piece (download a copy).
