Techniques to visualize occluded graph elements for 2.5D map editing

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

We propose an interface with two novel techniques to visualize occluded graph nodes and edges that help the user edit map data with a 2.5D geographical structure (e.g., multi-floor indoor maps). We first design a visualization technique -Repel Signification- that employs micro-animation to signify the graph elements that are overlapping with each other (and potentially erroneous). We also design a technique that enables the user to edit the occluded components with Expansion Interaction, which simultaneously visualizes both in-floor and across-floor occluded connections between the map elements. The combination of the two methods would enable the map editors (non-experts) to effectively find and fix erroneous data in 2.5D maps without changing the operation manner from the existing 2D map-editing interface.
