The Purdue RVL-SLLL ASL Database is "an extensive database of American Sign Language (ASL) motions, handshapes, words and sentences." This document describes the structure and workings of the web user-interface to the database.
Two additional documents provide important information on the data contained in the database. The technical report [1], lists each handshape and paragraph contained in the database and gives instructions on how to use the graphical user interface (GUI). The paper by Martinez et al [2] gives further details of how the images were obtained, including the lighting conditions and the background of the signers. Both documents are recommended to anyone working with the database.
The database is accessed primarily through a java applet which runs on the client side. This applet connects to a custom JDBC server (the "ASL Server"). This server performs queries to the database on request from the applet and creates a new webpage for the main query. The applet then directs the user's browser to this new page.
