Consumption as a Rhythm: A Multimodal Experiment on the Representation of Time-Series

Through Data Visualisation and Sonification models, we present a study of multimodal representations to characterise the Portuguese consumption patterns, which were gathered from Portuguese hypermarkets and supermarkets over the course of two years. We focus on the rhythmic nature of the data to create and discuss audio and visual representations that highlight disruptions and sudden changes in the normal consumption patterns. For this study, we present two distinct visual and audio representations and discuss their strengths and limitations.
