18. How INFO 6410 Fits into the Computer Science Curriculum Most courses teach underlying technology –compilers, operating systems, databases, etc. INFO 6410 concerned w/ design & evaluation –technology is simply a tool to evaluate designs by prototyping –build skills that will be important upon graduation design & evaluation creating complex systems working on large teams communicating results CSE441 - Spring 2013Advanced User Interface Design, Prototyping, & Evaluation 18
