The client needed a mobile tablet app to serve as a bridge between the technician and the machine. To achieve this, I collaborated with a team of industrial designers to develop a streamlined workflow and interface. This guided users through the entire process, from initial test setup and profile management to facility map handling and final report generation. We defined the necessary steps for completing the test after sample collection by consulting with the company’s science advisors and software developers. Our initial handwritten notes and diagrams evolved into wireframes, which I enhanced with stylized GUI elements aligned with their branding. Given that the CERTUS brand was still in its early stages, we had the opportunity to influence the graphic design, including the use of color gradients, icon styles, and integrating elements of their logo as supportive graphics in the GUI and other materials.
