A Unified Look at Cultural Heritage: Comparison of Aggregated Scanpaths over Architectural Artifacts

Abstract

The paper contributes to scanpath bundling methods. We propose an analytical approach for statistical comparisons of aggregated scanpath visualizations by means of second-order gaze analysis metrics. The present study explores differences in attention distribution and cognitive processing over architectural objects between architects, art historians, and non-experts. The results show between-group differences in attention dynamics of the aggregated scanpaths. The aggregated scanpaths of both expert groups were focal, while non-experts' scanpaths were ambient. Experts also paid more attention to and tended to remember better the architectural details and their location. The discussion explores the scalability of the proposed approach for Human-Computer Interaction and accessibility technologies designed to enhance the experience of cultural heritage.
