UX and Interface Design for Embedded Systems is the first of three classes in the Embedded Interface Design (EID) specialization, an online version of the on-campus EID class taught in graduate embedded systems design. This first course is focused on user experience (UX) and the related methods, practices, and principles that will help ensure your embedded interface designs for devices and systems are what your users both need and want. The class includes an introduction to UX, and then a four phase breakdown of a typical UX design process, including planning, user research, design methods, and testing for verification and validation. Much of the content provides generally applicable UX techniques, but particular focus is included for considerations in developing embedded devices. The class includes practical projects that let you try some of the key methods in a thorough interface design process.
Introduction to UX and UI
-An introduction to User Experience (UX), User Interface (UI), and usability concepts and definitions as they relate to embedded systems and interface development in particular and in general. Includes a comparison of formal UX studies vs. the discount methods reviewed in the class for practical work on UX in design projects. Also a look at some human characteristics that impact the design of embedded interfaces.
UX Analysis and Planning
-A walk through early planning and analysis stages for UX projects: why the planning matters, methods that can be used. Introduces the Work Breakdown Structure (WBS) as a key approach to scope project tasks. Also includes an early look at potential interface components that may be used in embedded designs.
-Focus for this module is on user research - understanding who the users are, what are they trying to accomplish, how can your interface design support and delight them. We review a number of approaches to structuring, performing, and documenting user research, including a special focus on personas of different types and on use cases, both in text and in UML (Unified Modeling Language) graphical formats.
-This module looks at integrating user needs, tasks, and concerns into our UX and UI design work. Standard methods for UX design will be presented, with a particular focus on usability heuristics, a proven approach to assessing and improving an interface design, and on various forms of sketching, an important design tool for every design engineer's toolkit.
UX Verification and Validation
-This final module looks at ways to verify the embedded interface designs we've created are acceptable and valid to our users. A number of common testing and related UX methods are reviewed, with some detailed looks at the use of industry standard surveys, like the SUS (System Usability Scale), and the application of statistics to support qualitative UX work with some quantitative measures where needed.
