Automotive Infotainment System Design
Project Overview
Many OEMs introduce infotainment systems with outdated graphics and poor user experience, often misaligned with the car's overall design. As a result, users frequently rely on third-party systems like CarPlay or Android Auto to get a more modern and intuitive interface.

One of my main goals was to design a built-in system that feels up-to-date and visually timeless, eliminating the need for external solutions.
The focus was not only on aesthetics but also on user experience, ensuring that interactions are seamless, ergonomic, and safe.

In a world where physical buttons in cars are being increasingly replaced by touchscreens, I aimed to create an infotainment UI that is both modern and familiar, resembling the devices we use daily. By prioritizing clarity, efficiency, and minimal distraction, the system enhances usability without compromising safety on the road.
My Contributions
I designed a UI kit that defined typography, iconography, and visual components, ensuring consistency across the system. Based on this foundation, I created layouts for each app, from navigation to media playback and phone connectivity,  prioritizing simplicity and accessibility. Given the shift away from physical buttons, I focused on minimizing cognitive load by optimizing UI placement and interaction flows.

A key aspect of the design was the adaptive home screen, where widgets resize dynamically based on context. For example, navigation takes priority while driving, keeping maps large and visible, while secondary functions like media shrink to avoid distractions. I also rethought the menu structure to simplify navigation, ensuring that key features are accessible with minimal steps.
The project began with an in-depth study of which functions should be developed for the car’s interface and which should remain as physical controls for safety reasons, for example, climate controls and volume adjustments. The next step was to prioritize these functions based on their relevance to the driver and their impact on safety.

With this hierarchy established, I moved on to sketching the interface on paper at real-life dimensions and testing it directly in my car. This hands-on approach ensured that buttons were properly sized, easy to reach, and intuitively placed.

Once the core layout was validated, I transitioned into designing the UI components and refining the visual system, maintaining a balance between clarity, ergonomics, and modern aesthetics.

The result is a driver-centric infotainment system that is both intuitive and distraction-free, aligning with contemporary UX standards while keeping the driver’s focus where it belongs: on the road.
