An Akashic Desktop Recorder for Resumption of Works

Abstract

In this study, we developed a system that records the PC user's past work and enables the user to resume a previous task. Previously, we used screenshots to record work processes. However, this method demands a huge storage capacity. Therefore, in the proposed system, duplicate screenshots are deleted through similar-image determination. In addition, screenshots are transformed into a compressed moving image by introducing the H.264 video coding standard. Moreover, we integrate a backup system into our system to help users reach files based on their queries. The information on the user's past work is organized in Research Episode Networks, which are graphs representing relationships among events, tasks, and files. Research Episode Networks make it easier for users to search for target files.
