An interface is the link between a person and a designed object. The interface communicates how that object is to be used, and how it creates an experience for its user. Interaction design is the process of creating interfaces that define the behavior of the designed object, encompassing both usability and aesthetic dimensions of the artifact. In this course, we will explore issues that pertain to the design of visual, multimodal and tangible interfaces. The class will focus on elements of the larger interaction design process including basic design principles, information architecture and navigation, planning and brainstorming methods, and techniques for developing rapid sketches and prototypes. Course requirements: Fundamentals of Communication Design or equivalent course work are a required pre-requisite for this course. Students are expected to have prior experience using a variety of design and programming tools. Please speak with the instructor if you have questions regarding these prerequisites. Note: Students outside of HCII can sign up on the waitlist for this class, in the event that seats become available.
