Big Brother Is Watching You - Now in a Doubleplusgood Way

摘要

This paper reports on the progress made with our X Marks The Spot (XMTS) system. In XMTS we make a fundamental change to the compositing operation in a desktop manager, storing all text-display events and their related raster-draw events. This means we can provide the user with a search interface that allows them to go back in time and view how their desktop used to look. Because XMTS is aware of what text was drawn into which window and at what position, the provided snapshot is semi-interactive in that the user can bring individual windows forwards and backwards, and copy text from them. In previous work we demonstrated the approach is technically feasible. In this paper we detail infrastructural advances we have made and showcase its new search interface.
