Study 7/0: Error-Generated Animation

Study 7/0 visualizes the positioning errors of a static GPS receiver. It was motivated by the idea of cognitive mapping as a configuration of individual, non-linear, and discontinuous spatiotemporal experiences, and their outcomes. We use technical flaws and/or imperfections as generators of conceptual source material for further creative processing and expression, unlike glitch art, which typically uses errors as the aestheticised frontline layer. With Study 7/0, we explore the effective approaches to emergence in generative art, where a simple initial setup of a complex system can produce surprising phenomena.

We secured a GPS receiver to a desk, powered it up, and let it run a draw track function for 7 days, 7 hours, 16 minutes, and 11 seconds. While the ideal GPS plot for an immovable object is a single point, this setup recorded 8438 positions on a 34.7km long path covering an area of 2.1km2. The path is a consequence of the limited precision of a GPS receiver operating inside a building under changing weather, combined with the inaccuracy of GPS infrastructure.

Taking all the recorded time-stamps and 3D positions, we animated the horizontal locales (long./lat.). In the first animation we isolated the current 2.25% (780m) section of the path, revealing the error-generated dynamics. In the second one, we followed the current 2.25% of the building to draw a complete route. Each animation is about 5 minutes long and displays all the values from the dataset.
