Embedded Linux offers vast opportunities, yet building high-performance user interfaces for embedded devices demands deep expertise due to:
Embedded GUI development is more than just design – it’s about technical depth and tailored integration.
Building user interfaces for embedded systems means balancing tight hardware limits, diverse platforms, and rising expectations for intuitive UX. Time-to-market pressure adds another layer of complexity.
At Antunes, we bring together deep technical expertise in embedded Linux, low-level integration, and middleware architecture – with a practical mindset for UI/UX. The result: graphical interfaces that are fast, stable, and seamlessly integrated into your system environment.
We design GUIs that match your hardware architecture and screen characteristics – scalable, responsive, and ready for deployment.
We engineer interfaces that run smoothly under limited CPU, memory, and power – without compromising on user experience or reliability.
We bridge the gap between IoT logic and human interaction: intuitive interfaces, clean UI flow, and seamless backend integration.
Our services go far beyond just building interfaces. We design embedded GUI systems that are technically sophisticated, highly performant, and purpose-built to give your product a lasting edge – even under tight hardware constraints.
We don’t follow industry defaults. We challenge them – using modern Microsoft-based frameworks to build future-proof, cross-platform GUI systems for embedded Linux.
Instead of conventional embedded frameworks, we use .NET 8/9 with Uno Platform and MAUI to create highly maintainable and scalable GUI applications.
Uno enables WebAssembly, Skia and native Linux UI layers, ideal for demanding GUI scenarios. MAUI adds mobile and hybrid hardware flexibility.
Result: Long-living, high-performance GUI systems – without vendor lock-in.
Our GUIs are engineered for performance from day one. That means fast rendering, minimal resource use, and zero compromises on stability – even on single-core, low-RAM devices.
Benefit:
We target resource-constrained platforms like battery-powered devices, IoT nodes, and edge controllers:
All GUIs are tested under real-world hardware limits – and designed to remain stable, responsive and efficient throughout their lifecycle.
Embedded UX That Actually Works in the Real World
We design for users, not just screens – with UIs that are readable in sunlight, operable with gloves, and usable without manuals.
Benefit:
We design intuitive UIs for small touchscreens – with pixel precision, responsive layouts, and gesture-optimized interactions.
Whether it’s a 240×360 px wearable or a 4K industry display – we craft UIs for clarity and usability:
Our GUIs are engineered for usability and joy – even on minimal real estate.
Plug-and-Play Integration with Your IoT or Middleware Stack
Our GUI layer is no silo. It’s a fully integrated part of your ecosystem – connecting seamlessly to your device logic, data layer, and cloud backends.
Benefit:
Our GUI solutions integrate cleanly into existing middleware, device protocols, and cloud platforms – while remaining hardware-independent.
Modern GUIs are part of interconnected systems. We focus on:
Your interface becomes the control hub – connected, smart and streamlined for growth.

Learn what really matters when building graphical user interfaces for embedded systems – compact, actionable, and rooted in real-world challenges.
Topics covered:
Whether in aviation, industrial control or smart city applications – our GUI solutions are developed in the challenging intersection between demanding usability requirements and harsh system conditions. We rely on modern frameworks like .NET MAUI and UNO Platform running on Embedded Linux to deliver cross-platform, high-performance, and long-lasting interfaces.
Proven in Harsh Conditions: Certified GUI for Aviation
One of our most demanding projects involved developing a cockpit UI for a helicopter system – running on a 3-inch screen, with limited memory, and no standard network connectivity. Communication had to work via a custom, certified protocol, and the device needed to operate for several hours on battery power – under full load. Despite these constraints, we delivered a fully aviation-certified, highly intuitive interface.
Compact. Energy-efficient. Certified.
Modular and Scalable: GUI Middleware for Industrial Device Management
In an ongoing large-scale project, we developed a scalable middleware UI for managing and controlling a diverse range of field devices – from sensors to actuators, using various industrial protocols. Originally built with .NET Core, the system was migrated to Embedded Linux for enhanced flexibility, better integration, and future-proof scalability. The interface is optimized for clarity, responsiveness, and real-time performance, even under high system load and active data traffic.
Flexible. Real-time capable. Extendable.
Mobile and Intuitive: Smart GUI for Sensor-Based Applications
For mobile use cases like SmartSense, our focus was on seamless UX and real-time feedback. The result: a touch-based app that automatically detects compatible devices, displays sensor data (e.g. temperature, light, humidity) in real time, and allows for custom automation workflows. Energy-efficient background communication (via Bluetooth or WiFi) ensures smooth operation – even across changing environments.
Intuitive. Mobile. Context-aware.
Certified GUI for secure airborne communication
Custom touchscreen interface for helicopter cockpits. Enables telephony and video system control on a 3" display – with flight approval and without classic network dependencies.
Compact. Energy-efficient. Certified.
Scalable middleware GUI for managing connected devices
Modular interface to configure and control heterogeneous field devices using MQTT and other protocols – designed for long-term maintainability in complex industrial environments.
Flexible. Real-time capable. Extendable.
Mobile UI for Smart Home and City devices
App interface for Bluetooth- and WiFi-based sensors – detects compatible hardware, enables custom automations and displays live metrics in a touch-optimized, minimal UX.
️ Intuitiv. Mobile. Context-aware.
Creating effective embedded GUIs takes more than just good design – it requires engineering precision, industry insight, and a deep understanding of the user context.
At Antunes IT Services, we combine all three: from architectural design to seamless deployment on real hardware. Whether it's a touchscreen cockpit interface, a scalable device control system, or a mobile UI for sensor-based applications – our solutions are not just front ends, but reliable, deeply integrated systems built for the real world.

How to contact us:
Every project begins with a targeted analysis of your users’ needs and context. We conduct user interviews, build interactive prototypes, and run usability tests early in the process. This ensures we design interfaces that feel intuitive from the start – not ones that need to be explained.
Yes. We develop cross-platform solutions using frameworks like .NET MAUI, Blazor, and Uno Platform. From the start, we take into account different hardware profiles, screen sizes, and performance classes. We also test on real target devices to ensure a consistent user experience across the board.
We use a modern .NET stack that integrates front end, middleware, and backend in one ecosystem. This reduces friction and speeds up development. Thanks to C# and XAML, we can cover a lot from a single codebase – which positively impacts maintainability, scalability, and overall budget. For UI design, we use Figma; for development, Visual Studio – both fully integrated into our workflow.
From day one, we analyze your existing systems – including APIs, data flows, and expected load. We integrate the GUI via clean APIs and robust protocols, always with performance in mind. We optimize with caching strategies, lazy loading, and real-world load testing. If necessary, we fine-tune at the protocol level to ensure stability even under heavy load.
We define KPIs with you early on, such as user adoption rate, interaction times, or error frequency. Before going live, we conduct User Acceptance Tests (UAT) with actual users. After the rollout, we continue to support you with usage monitoring, feedback loops, and practical improvement recommendations based on real-world usage.
