This subject imparts knowledge on usability design principles and their role in the design of intuitive and robust user interface (UI) and user experience (UX) applications across a variety of platforms. As a result, students acquire practical experience through the use of wireframes and prototyping that subsequently contribute to the development of effective UX designs. To aid this acquisition of knowledge and skill, this subject employs numerous case studies and showcases many examples of viable UX designs while also addressing the standards that test applications for usability.
