Designing interfaces for connected vehicles involves dealing with a very specific context: users are on the move, their attention is divided, and in many cases, they can't interact with the interface the way they would with a mobile phone or computer. Therefore, UX/UI design in this field must be guided by a series of fundamental principles that guarantee safety, efficiency, and usability.
Visibility and legibility
Visual elements should be clear, contrasting, and visible in different c level contact list lighting conditions (such as direct sunlight or night driving). Font sizes, icons, and colors should be carefully selected so they can be interpreted at a glance, without requiring excessive eye aversion.
Reducing cognitive load
Information should be organized in a hierarchy and simplified. The fewer decisions or actions required to achieve a goal, the greater the user's safety. The design should avoid cluttered screens or complex sequences that could cause confusion while driving.
Safe interaction (minimal distraction)
Each gesture or interaction should be able to be performed in a few steps and without requiring sustained attention. It's essential to design for minimal distraction, favoring quick actions, immediate feedback, and easily identifiable tactile elements, such as sensitive areas with raised surfaces or vibrations.
Multimodal design (voice, touch, gestures)
Current systems allow for the combination of multiple forms of interaction. Designing interfaces that integrate voice, touch, and, in some cases, gestures or eye gaze control improves accessibility and efficiency. The challenge lies in coordinating these channels coherently, allowing the user to switch between them intuitively.
Connected Interface Use Cases
Connected vehicles offer a wide range of features that transform the driving experience into something more comprehensive, interactive, and personalized. Each of these features represents a use case that requires specific UX/UI design approaches. Below, we review some of the most relevant ones:
Smart navigation
Navigation systems are no longer limited to displaying a map and calculating routes. They now integrate real-time information on traffic, weather, accidents, and low-emission zones. The design of these interfaces must offer clear and adaptive guidance , with well-synchronized visual and audible prompts, and maps that dynamically adapt to the context, without cluttering the screen with information.
Multimedia control and voice assistant
Music playback, podcasts, or calls must be manageable without diverting attention from the road. Voice assistants play a key role here, and the design must make them easy to activate, offer simple visual feedback, and allow the user to confirm actions without distraction. Furthermore, touch controls must be large, accessible, and consistent with common gestures.
