My project with SIP Communicator as part of the Season of Usability was to evaluate the interface of SIP Communicator, find out how SIP Communicator measured up with competing IM projects, and do an exploratory study to determine priorities for future improvements based on user requirements.

During the course of this project I work with Raphael Wimmer, my usability mentor, and Emil Ivov, creator of the SIP Communicator project, being able to work with both of these individuals helped me get a sense of the impact this work was having and would have for the future of SIP Communicator’s interface.
