In this paper we present CandyTop Interface, a visualization method with positive attention for growing multimedia documents. Our method is a visualization method for growing documents by allocating changes of multimedia documents according to time line in three-dimensional space. The main feature of our method is to enable provision of positive attention on key changes of multimedia documents by visualizing multimedia documents with priority of changes for multimedia documents. By our method, we can realize multimedia systems providing at-a-glance view for multiple versions of multimedia documents. In this paper, we discuss the feasibility of our method by applications to visualization for growing documents with collaborative editing in virtual spaces and for multi-view video streams of technical meeting.
