The aim of this project was to design the interface of the controls systems used while driving the Uniti electric vehicle (EV).  The technologies included in the vehicle are a full-screen augmented reality heads up display and a steer by wire system, this resulted in a new interface layout developed by Uniti AB. This layout differs substantially from the traditional layout found in most cars and consequently a new design for the driver operated control systems was needed.

Usability was key for the project’s development due to its direct implications upon the success a user can have while performing a task within the interface. Usability was improved by testing the solutions through formative evaluations, which provided an idea of what users were experiencing while trying the interface. It was essential for the project to meet the functional requirements of the control systems while taking in consideration regulations and legislations, but without forgetting the company’s goal of providing a futuristic user experience.

The solutions that integrate the final iteration are focused on providing significance to the user based on their previous experience and pattern recognition. The interface is based on the general outline developed by Uniti AB and adds nine interactive elements to it:  two haptic touch panels located on the sides of the console, a button in the central part of the console, two sliders on the sides of the steering controllers, two buttons on the upper part of the steering controllers, and two haptic touch panels in the upper surface of the steering controllers.
