Photo4Action: phone camera-based interaction for graph visualizations on large wall displays

摘要

We present Photo4Action, a system that integrates mobile devices and large wall display devices for efficient network visualization. Our work allows users to locate a region of a large graph visualization on a wall display by photo taking. An efficient match algorithm is proposed to match the subgraph users select with the full graph. Sets of interaction techniques have been designed to support various graph exploration and visualization tasks. The system also supports interactions for multi-users' collaborative analysis for graphs. We also report the interaction patterns and collaboration behaviors of users during the visual exploration as observed during our study.
