Interaction design courses can help you learn user research techniques, prototyping, usability testing, and the principles of visual design. You can build skills in creating user personas, designing wireframes, and conducting A/B testing to refine user experiences. Many courses introduce tools like Sketch, Figma, and Adobe XD, that support creating interactive prototypes and visual assets. You'll also explore methods for gathering user feedback and iterating on designs to enhance usability and engagement.
