This publication discusses a user interface method that allows the creation of simple or complex boolean expressions without requiring the user to explicitly type text-based statements with AND and OR operators, special keywords, paired parentheticals, or comma delimiters. This method has been implemented in IBM WebSphere Everyplace Access (WEA) software as part of Everyplace Synchronization Server (ESS), a component of which provides filtering capabilities for client-server synchronization of mail, contacts, tasks, events, and memos. Prior to the implementation of the user interface described herein, the user created these filters by writing boolean expressions. This technique was shown to be extremely error-prone in user interface evaluations, with very few users demonstrating success in creating even a simple filter. Using the technique of this publication, filters were correctly created at a success rate near 100 per cent.
