This document discusses mobile document summarization and browsing applications. It introduces the need for accessing large documents through mobile devices due to increasing mobile internet usage and fast-paced business decisions. Summarization and hierarchical displays are effective methods for browsing documents on small screens by condensing information and allowing users to expand subsections. Several top word processing applications for mobile are also reviewed, including Pages, Google Docs, iA Writer, WPS Office, and Microsoft Word.

Architecture for
Accessing Large

Mobile Devices
Lecture 4

2. Introduction
• Access to the Internet through mobile devices is
growing significantly in recent years.
• Mobile computing should be extended to
decision support in an M-Commerce
organization. With a fast-paced economy,
organizations need access to large documents
or other information sources for fast decision
making.
• As a result, there is an urgent need of a tool for
browsing large documents on mobile devices.

3. Constraints of mobile devices
• Low bandwidth
• Small resolution
• Information overloading
• Visualization of information on small
screen

4. Summarization
• Automatic summarization summarizes a
document for users to preview its major
content.
• Users may determine if the information
fits their needs by reading their
summary instead of browsing each
whole document one by one.

5. Summarization on Mobile Devices
• The document summarization on mobile
devices must make use of a “tree view” or
“hierarchical display”
• Similar techniques have been applied to
Web browsing : an outline processor
organizes the Web page in a tree structure,
and the user clicks the link to expand the
subsection and view the detail.
• Hierarchical display is suitable for
navigation of a large document, and it is
ideal for small area display.

worry about losing service.

with some enticing features for iOS or Android
users. It features a touchscreen keyboard with a
row of special punctuation characters, allowing
more fluid typing and editing.
