Effective product selection in electronic catalogs

Product catalogs are crucial for electronic commerce on the Internet, but it is still a challenging task for casual users to perform effective product selection. Recently, a promising technique for product selection has been proposed: Incremental restriction on interactive tables. It allows customers to build complex queries with a few mouse clicks, but still to browse the available products at any stage. This paper describes effective and ineffective strategies of users working with this technique. These strategies were identified in a study with casual users.
