Technical Capabilities

What We Work With

End-to-end HMI expertise from Figma wireframes to production-optimised embedded GUI firmware across every display and input technology.

We design and implement HMIs that operators actually enjoy using combining clean UX design with low-level display driver expertise to deliver smooth, responsive interfaces.

Why Invest in HMI

Why Invest in Custom Embedded HMI?

A well-designed HMI reduces operator errors, shortens training time, and differentiates your product — often being the first thing customers notice.

01
Operator Efficiency

Task focused layouts reduce interaction steps, training time, and human errors measurable improvements in productivity and safety.

02
Low-Resource Rendering

LVGL delivers smooth 60fps animation on MCUs with as little as 64KB RAM and 1MB Flash no application processor required.

03
Custom Branding

Your colour palette, icon set, fonts, and animations pixel-perfect to your brand guidelines, not a generic widget library.

04
Multi-Language & RTL

Unicode, right-to-left Arabic/Hebrew, CJK character sets, and runtime language switching for global product deployment.

05
Safety-Critical Compliance

IEC 62366 usability engineering principles for medical devices, industrial equipment, and automotive driver displays.

06
Native & Web Options

Deploy as an embedded native HMI or Web HMI on embedded Linux same logic layer, different presentation layer.

How We Work

Our HMI Design Process

From operator research to performance-optimised embedded GUI a design first process that ensures your HMI is right before a single line of code is written.

01
UX Research & Wireframing

Operator workflows mapped, screen hierarchy designed, Figma wireframes created and reviewed.

02
Visual Design & Prototype

Colour palette, typography, icons, and animations designed and previewed in the LVGL or Qt simulator.

03
Framework Setup & Theme

LVGL/Qt theme created, custom fonts embedded, display and touch drivers integrated.

04
Screen & Widget Development

All screens coded, transitions animated, input events handled, and data bindings wired up.

05
Performance Optimisation

Frame rate profiling, memory usage tuned, display tearing eliminated, and touch latency minimised.

User Testing & Delivery

Real-user testing, final refinements, source code, assets, and documentation handed over.
