Display and HMI Design
Human-machine interfaces designed as one system: the display, the controls, the electronics behind them and the firmware that makes them feel responsive.
An interface is where users decide whether a product feels finished. We design custom HMIs for products and equipment, from control panels and handheld devices to consumer appliances, covering display selection and integration, touch and tactile controls, and the embedded GUI that runs on them.
What this includes
- LCD, OLED and e-paper display selection and integration
- Capacitive touch design and controller tuning
- Rotary encoders, dials, buttons and tactile controls
- Embedded GUI development on microcontrollers
- Control panels and front panels for equipment
- Enclosure, cover glass and front panel mechanical design
Hardware, firmware and UX under one roof
Most HMI problems sit between disciplines. A display that looks good on the bench but lags in use, a touch panel that misfires when the enclosure is fitted, or a control that feels cheap because the mechanics and firmware were tuned separately. Our electronics, firmware and mechanical engineers work on the same project, so the display, the controls, the enclosure and the software are designed against each other from the start.
Display selection and integration
We integrate LCD, OLED and e-paper displays, and choose between them on readability, power, lifetime and supply risk rather than habit. That covers interface and driver design, backlight and power control, optical bonding and cover glass choices, and checking that the part will still be available for the life of your product. E-paper suits low-power and always-on readouts; TFT LCD suits rich graphics; OLED suits high contrast in compact products.
Touch, tactile and physical controls
Not every product should be a touchscreen. Gloved hands, wet environments and eyes-free operation often call for physical controls, and we design both: capacitive touch with controller tuning for the real enclosure and cover material, and tactile controls such as rotary encoders, detented dials, buttons and faders where precision and feel matter. Our Njori Dial work is an example, a patented removable rotary dial with 240 distinct positions that controls a cooker through a sealed glass surface.
Control surfaces for broadcast, audio and live events
Our team includes engineers with backgrounds in radio broadcast equipment design and live event production. We understand how operators use control surfaces under pressure, why latency and reliable feedback matter more than visual polish, and how equipment has to integrate with existing audio, lighting and DMX control systems. If you are developing a control panel, controller or interface product for these markets, we can bring that operational context to the design.
Embedded GUIs that stay responsive
We develop the graphical interface that runs on the device, sized to the microcontroller or processor it runs on. Responsiveness is designed in through frame budgets, input debouncing and acceleration, and partial screen updates, so the interface feels immediate rather than laggy. Where power matters, the display and GUI are part of the power budget from the start rather than an afterthought.
Common questions
Can you design a complete HMI, hardware, software and enclosure?
Yes. We design the display and control electronics, write the firmware and GUI, and design the front panel or enclosure around them. You get one team responsible for how the whole interface works rather than three suppliers pointing at each other.
Are you a display or AV integrator?
No. We do not install displays or AV systems in buildings or venues. We design displays and controls into products: equipment, devices and control panels that you then manufacture and sell. We can also manufacture short runs of those products for you.
Touchscreen or physical controls?
It depends on who uses the product and where. Touchscreens are flexible and cheap to change in software; physical controls are faster, work with gloves and wet hands, and can be used without looking. Many good products combine both. We will recommend what suits your users rather than defaulting to a screen.
