In addition, given the rotation that exists in the use of a machine, any new operator must be able to comprehend how to interact with it in a very basic and clear manner. As a result, we worked hard to create an experience that was both clear and intuitive. Web usability patterns were extended to touch displays during the UX phase. And we achieved that in a variety of ways, such as by making larger elements with more space between them, defining a clickable area that was larger than the symbol design itself, and adding pull downs and menus to the navigation.
Subsequently, the wireframes were examined to see where they could be improved. International users — Americans, Australians, and Japanese – were also tested remotely to ensure that the screens operated successfully in all markets.
Once the adjustments detected in the tests were made, the screens were designed. All of the machines' icons were also designed, resulting in a UI Kit and a design system that had to be consistent in terms of colors, body, fonts, icons, and interactive elements, with only minor changes (coming from the device is touch or click).
The project was presented to the development team in a technical session, during which we also provided them with our advice for which screen type they should implement to make the most out of the new designed experience, with all of its functions.
