Abstract:
The Internet has dramatically brought more and
more together buyers and sellers to the electronic
marketplaces. Despite a rapid growing of interest and
researches on the internet-based online e-commerce
systems, the design of efficient mechanisms for
navigating online product catalogs is still quite
limited, especially for online auctions. This paper
describes an interactively visual interface for
navigating product catalogs of large-scale online
auction sites. We use the ENCCON layout algorithm
to display the entire, as well as a portion of product
hierarchy. The display of the hierarchy is
accommodated with a focus+context viewing
technique for moving the interesting focus of users
around the product hierarchy. We have developed an
online auction prototype to simulate the ordinary
auction activities with the assistance of proposed
ENCCON visual interface.
