UI/UX HMI Design, Seat Automotive, Barcelona (ES)
Project collaboration between SEAT Automotive and Altran technologies working hand-to-hand with designers, developers, and engineers on advanced human-machine interfaces (HMIs) for confidential electric vehicles. Head-up displays or in-vehicle HMIs, are powerful graphical interfaces that enable the user/driver to stay connected with the vehicle. The UI/UX design role consisted of conducting multiple user-tests, optimizing graphics through weekly software-based simulations and hardware-prototypes, gathering weekly across different teams, fixing specific graphic issues or applying new graphic requirements according to usability principles, safety, and industry legalities. These included specific usability tests such as driving under real conditions both at Seat’s Infotainment center in Barcelona, and at VW's development center located in Braunschweig (Germany).
The UI/UX HMI development process included the following stages: (1) Brief delivery by VW with a set of specific graphic hierarchies and software specifications to Seat. / (2) Design development: the graphical user interface is prototyped and tested by using Elektrobit Guide Studio software and generated simulator builds. Newcoming issues are evaluated and solved across different teams. / (3) HMI behavior, usability, responsiveness, legalities, and layout are tested independently in all screen levels. / (4) New design requirements are validated and created for further improvements. / (5) Design meets both legal and technical demands.
