Abstract
This paper presents Pearl, a mixed-reality approach to the analysis of human movement data in situ. As the physical environment shapes human motion and behavior, the analysis of such motion can benefit from the direct inclusion of the environment in the analytical process. We present methods for exploring movement data in relation to surrounding regions of interest, such as objects, furniture, and architectural elements. We introduce concepts for selecting and filtering data through direct interaction with the environment, and a suite of visualizations for revealing aggregated and emergent spatial and temporal relations. More sophisticated analysis is supported through complex queries comprising multiple regions of interest. To illustrate the potential of Pearl, we develop an Augmented Reality-based prototype and conduct expert review sessions and scenario walkthroughs in a simulated exhibition. Our contribution lays the foundation for leveraging the physical environment in the in-situ analysis of movement data.

Supplemental Material
Moreover, we offer recorded human movement data based on our demo room. You can find a detailed README.md within the folder that highlights the files and folders.
We also provide all materials related to the expert review study. This includes 1) a pre-study questionnaire 2) PEARL system introduction slides 3) a guided walkthrough script 4) Envisioning scenario feedback session reading materials 5) Post-Interview questions. You can find a description of our study procedure in Sec. 6.3 of our paper.
Additionally, transcribed expert review study comments are offered. Each session is roughly grouped by the blocks present in the semi-structured interview block.
Lastly, PEARL prototype is openly available on GitHub.
