"Pockets Full of Memories" is an interactive installation that consists of a data collection station where the public takes a digital image of an object, adds descriptive keywords, and rates its properties using a touchscreen. The data accumulates through-out the length of the exhibition. The Kohonen self-organizing map algorithm is used to organize the data, moving the images of the objects into an ordered state according to similarities defined by the contributors’ semantic descriptions. The archive of objects is projected large-scale on the walls of the gallery space showing various visualizations such as the objects positioned in the 2D matrix, their movement over time, and textual descriptions. The audience can also interact with the data online to access descriptions of the objects and to contribute comments and messages to each object from anywhere in the world.
At the start of the exhibition, the database is empty but grows through the public’s contributions. The algorithm organizes the data throughout the exhibition to arrive at a final ordered state at the end of the exhibition. The phenomenon of proceeding from small local actions (each contribution) to arrive at a final ordered state is called emergence as the order is not determined beforehand but emerges over time through the local interactions generated by the algorithm each time a new object enters the database. In this sense, the system has been defined as 'self-organizing'.
