Abstract

AfterImage is an interactive wall consisted of light detecting units controlled by microprocessors. Each light-sensing unit determines user proximity through the intensity of the shadow being cast, turning these shadows into bright snapshots portrayed through built-in LED lights. AfterImage extends the concept of memory to a space and location by imitating two unique characteristics of human memory: a lingering afterimage effect for intense stimuli, and a flashback of events that happened in the past. To create a more organic representation of flashbacks, a native data structure was explored. Through the collection and reproduction of geospatial memory, AfterImage attempts to change a user's perception of existence and connection between users across time. This paper discusses the development and production of AfterImage as a piece of public art.
