Eyes in the clouds: spatial data analysis with gaze-enhanced point clouds

Abstract Spatial data analysis is essential in domains such as construction, architecture, and geodesy, to check for differences between construction stages of a building. In this context, real-world environments are often digitally recorded as point clouds, providing a basis for digital processing and analysis. Furthermore, aspects of spatial cognition, often measured with eye tracking, are also relevant to many research questions related to how people perceive and understand space and spatial
