In-Depth Information
awkward conversation and facilitate meaningful exchange by allowing users to select
to engage other users with interest characteristics especially meaningful to them.
The user nodes will display the ratio of interest within a topic by the length of up to
12 colored beams (representing subgenres) and the amount of knowledge of the topic
by the size of the gray circle (Fig. 1). The colors of the beams are selected based
on the PCCS (Practical Color Co-ordinate System), and the beams are placed clock-
wise around the node starting with red at 12 o'clock, with intervals between beams at
360
[no. subgenres] degrees. In the case of music, the ratio will be [no. plays within
genre]
/
[total no. plays].
In addition to visualization of user interests, integrated presentation of information
from Wikipedia, Amazon, YouTube, o
/
cial sites, and more during conversation will
help facilitate meaningful exchange. This system will o
er two operation modes, ”trace
mode” and ”timeline mode.” Trace mode will allow users to find queries to search for
information they feel they needed during conversation with other users, based on the
visualized interest information of other users. Timeline mode displays information on
the query clicked in chronological order. This function enables users to view videos of
interest, encyclopedias, or shopping sites while remaining on the website, and to have
other users recommend new content to them. Timeline visualization is proven to be
useful for displaying integrated events with chronological information[14], but in this
project it will be used to search for information on graphical content while communi-
cating with multiple users.

Structure of Proposed System
3.1
System Structure
The proposed system consists of a data input section, a database section, and a data
output section. The data input section will receive user input and RSS information from
web services. The database section will structure data and export it in XML format. The
data output section will analyze the XML and visualize the information (Fig. 2). The
interface consists of: the main panel, which displays interest information(1); the infor-
mation panel, which displays detailed interest information(2); the picture panel, which
displays video sharing website YouTube(3); the icon panel, which displays the pages
of encyclopedia website Wikipedia and shopping website Amazon(4); and the com-
munication panel, used to communicate with other users(5) (Fig.3). The main panel
will display information in either trace mode or timeline mode (Fig.4). The information
panel gives the user detailed information such as top 10 favorite works or chronologi-
cal tables. The communication panel allows the user to communicate with other users,
