Spatial Objects Indexing and Retrieval for Mobile PowerPoint

Abstract

Different from the traditional office software, due to the limited storage and computational capability of mobile devices, how to support the page editing in a fast and energy efficient manner is fundamental. To address this challenge, we propose an MR*-tree based indexing mechanism for supporting the fast and energy-efficient retrieval of spatial objects in mobile PowerPoint pages. Based on which, techniques are developed to support the operations when editing mobile PowerPoint pages. Prototype has been implemented for supporting the operations of spatial objects in editing mobile PowerPoint pages.
