Visualizing users' function-execution history of software to support function discovery

摘要

We are conducting a research on sharing usage knowledge of software functions according as the functions that are needed by users who use the same software for similar purpose are similar. In this paper, we propose a visualization method of histories of function executions collected in long period. The proposed method enables users to identify functions that are unaware of by them. We evaluated the proposed method adapting the method to MS Word and PowerPoint. Experimental result shows that all subjects can discover functions unaware and that the 34.5 functions out of discovered functions of PowerPoint are useful for the subjects.
