UX Research
It is specifically dedicated to learning about and gaining insights into a product’s users, they are involved in a project at the earliest stages of the design process. This is when they will conduct a comprehensive investigation of a product’s users and create reports about the user pain points and user insights.
UI Design
UI design focuses on the user’s visual experience. It determines how a user interacts with an interface—be it an app, a video game or a website. It’s all about how the user navigates from A to B via different visual touch points. Think tapping a button or swiping through pictures.
Prototyping and Testing
Generating an interactive final version of the product, which is either clickable or tangible. Testing of a product is taking feedback from user that product is understandable or not, and then feedback is gathered based on their natural response rather than explicit questioning and reworking on it.
