Abstract
We propose a Drawing-Frequency based Layered (DFL) Canvas approach to reduce a synchronization delay in collaborative web applications. The synchronization delay consists of a network delay and a drawing delay. The network delay is well-argued topic by various researches. We focus on the drawing delay, which is a primary bottleneck of Canvas objects synchronizations. We introduce the DFL Canvas approach in order to solve the drawing problem. The DFL Canvas divides Canvas objects by drawingfrequency. We implemented a collaborative paper editing support system with the DFL Canvas. Users can edit the same document and share Canvas objects on papers in real-time on web browsers. We present an evaluation result that indicates the approach is suited for collaborative paper editing support systems.

Summary
We have developed a collaborative paper editing support system.[1] On the system, users edit papers and synchronize Canvas objects, defined in HTML5. We propose a Drawing-Frequency based Layered (DFL) Canvas approach for collaborative web applications. The DFL Canvas reduces a delay of Canvas synchronizations and we apply the DFL Canvas to the collaborative paper editing support system. A paperless environment is recently an attempt to distribute, manage, or read digital documents. Documents or papers are made as digital documents. More and more digital documents are distributed in conferences. Companies can decrease the cost and optimize the work by promoting paperless. The maintenance can become much easier with the use of efficient search and structure in paper-based filing system
