Usability (UI / UX Design)
The greater the mechanical complexity of a system, the greater the requirement in the development of a user interface that offers a simple, intuitive and amusing experience.
User Interface Design (UI Design)
Based on the usability study carried out, design of the user interface is created according to the brand concept and appealing to the user. This stage of the process involves the design of all iconography, signage, buttons and other elements that may become part of the system.
User Experience (UX Design)
The Usability Experience results from the concept defined in Usability and relates to all (ideally positive) sensations that the user takes when using a particular system (website or application, for example). These sensation may be the responsiveness of the touch, the texture, the sliding effect with which a message appears on the screen, among many other possible shapes.
