PhotoScope, a novel visualization, visualizes the spatiotemporal coverage of photos in a construction photo collection. It extends the standard photo browsing paradigm in two main ways: visualizing spatial coverage of photos on floor plans, and indexing photos by a combination of spatial coverage, time, and content specifications. This approach enables users to browse and search space- and time-indexed photos more effectively. We designed PhotoScope specifically to address challenges in the construction management industry, where large photo collections are amassed to document project progress. These ideas may also apply to any photo collection that is spatially constrained and must be searched using spatial, temporal, and content criteria. Design choices made when developing PhotoScope are also described.
Civil, mechanical and electrical engineers, and professionals from construction management validated the visualization mechanisms and functionalities of PhotoScope in a usability study. Empirical findings on the cognitive behaviors of participants are also discussed in this thesis.
