Cyber-Physical Directory with Optimized Visualization

The cyber-physical directory is proposed previously to enhance the effectiveness of current digital directories, which used the tag-cloud representation to make relevant information obviously bigger to users due to their interests. Such customized visualizations can speed up the information search for user social activities at a location. Unfortunately, such visualization poorly utilizes the total area of a directory display by leaving a lot of unused areas. This paper introduces a 3-step optimized visualization framework that solves this problem while preserving the advantages of tag-cloud representations. The proposed framework is successfully implemented for its feasibility, and is proved its high utilization and practicality to users in a real scenario.
