HCIL-93-12

I, Ben Shneiderman, declare as follows:

1. I am a Professor in the Department of Computer Science and Head of the Human-Computer Interaction Laboratory at the University of Maryland at College Park. My background and qualifications are detailed in my declaration of March 30, 1990 that previously was filed in this action.
2. I am making this supplemental declaration to provide further examples of design alternatives referred to in my prior declarations and to further identify the arrangement that is unique to Apple and that makes the overall appearance of the Lisa/Macintosh interface widely recognizable.
3. The Macintosh "Look and Feel." To understand the distinctive appearance of the Macintosh interface, known as the Macintosh "look and feel" or "the Macintosh look", one needs to consider not only the individual elements that make up the appearance of the interface but also the way those elements are arranged and interact with one another to create the consistent and distinctive Macintosh interface. One way to describe that look and feel is by reference to the folowing main features of the Macintosh interface. The alphanumeric designations appearing in bracket correspond to items from Apple's list of similarities.
