Comparing architectural designs as well as measuring their level of success is a challenging task. Tracking of occupant movements provides objective data facilitating the development of new metrics for evaluating spatial layouts. This paper starts by outlining an overall methodology for Spatial Layout Evaluation based on occupant movements. Then, a platform for acquisition and interpretation of objective data to better understand how space is utilized by occupants is introduced. This platform is the Trajectory Data Processing Framework (TDPF). It supports investigating correlations between occupant movements and problems associated with spatial layouts. Finally, as a proof-of-concept implementation of this framework, a set of tools for analysis of occupant interaction with layouts, called Occupant Layout Interaction Analysis (OLIA), is presented.
