Spreadsheets have become very popular tools for analyzing and visualizing data from business and science. To better understand human-spreadsheet interaction, we explore readers’ information models, but in contrast to most studies we focus on spreadsheet readers rather than spreadsheet authors. We conducted a study using the repertory grid technique and analyzed the result with the help of a Generalized Procrustes Analysis yielding a deeper understanding of human’s information model of spreadsheets. Based on this we envision new human-spreadsheet interactions to increase the readibility and thus, usability of spreadsheets.
