Human-Machine Interface

Introducing the world’s most powerful platform for developing automotive HMI.

Driving HMI innovation with UE5

From General Motors to Lotus, leading automakers are turning to Unreal Engine to power their HMIs. Discover how unmatched visual fidelity, creative flexibility, and performance are driving their decision.

Lotus

Lotus HMIs feature an interactive digital twin of the vehicle: any change made to the physical car, like opening a door, is instantly mirrored by a 3D model displayed on the dashboard.

Why choose Unreal Engine for HMI?

Pole-position visuals

⁠Unreal Engine sets the pace when it comes to HMI visual fidelity. Create beautiful, interactive 3D visuals thanks to best-in-class graphical capabilities and the industry’s leading deferred renderer. Bring the wow factor with a range of powerful tools all on mobile/embedded platforms.

Next-gen dashboard UX

⁠Create captivating in-car experiences with dynamic ambient lighting, an interactive digital twin of the car in the dash, and more. Delight users with downloadable content to customize the look and feel of their UI.

Design-driven development

Designers can contribute directly to the product using Blueprint visual scripting. There’s complete version control support, instant desktop previews, and the ability to customize the engine to your needs with direct access to source code.

Production-hardened tools

UE5 brings fast boot-up and frame rates, a fully optimized pipeline for automotive use cases, seamless integration into your current framework, and profiling tools like Unreal Insights to help hit performance metrics.

HMI features

Unified visualization

Android Single Instance Service 2.0, enables you to run one optimized Unreal Engine HMI instance across multiple in-car displays on Android-based systems. With numerous applications able to access the rendering output of this one service instead of spawning their own 3D rendering, you can shift up a gear when it comes to building modular, efficient, and high-performance automotive UIs.

Best-in-class rendering

Create beautiful, interactive 3D visuals thanks to Unreal Engine’s Deferred Renderer, which enables the seamless integration of rich 3D UI components with 2D HUD elements, superior handling of transparent materials and blending, and more. Anti-aliasing helps balance quality and performance, while Large World Coordinates unlock accurate navigation systems. Screen Space Reflections (SSR) bring realism, depth, and spatial immersion to reflective UI elements.

Enhanced developer efficiency

Unreal Insights helps you profile your system’s performance. Assess frame and rendering efficiency, visualize multi-threading performance, and identify hitches or delays in animated transitions. You can perform these assessments both on a desktop and directly on the vehicle’s System on a Chip (SoC). With APIGear, you can generate code that integrates your front and backend systems, connecting the logic and UI layers of your HMI.

Powerful design pipeline

HMI designers can animate design, prototype, and customize 3D interface elements directly in UE5. Unreal Motion Graphics’ Model-View-Viewmodel (MVVM) framework enables clean, maintainable, and data-bound interfaces. Font DPI Scaling ensures UI and text remain sharp across different screen resolutions. And the Common UI plugin provides a unified framework for building responsive, input-adaptive UI.
