The driver has a limited attention budget.

At speed, attention is expensive.

The driver is processing braking points, traffic, grip, balance, flags, temperatures, lap information, and what the car is doing beneath them. A control interface should reduce that workload, not add to it.

This is why racing hardware has to be designed around human behavior rather than simply around available space.

Touch matters.

A driver should not need to visually identify every control.

Button shape, rotary position, detent strength, paddle travel, and spacing all contribute to a mental map of the interface. Gloves make these distinctions even more important.

Good tactile design allows a driver to confirm an action through feel.

Information needs hierarchy.

Displays create the same challenge in another form.

Showing more data is easy. Showing the right data at the right moment is harder.

A driver should be able to recognize critical information in a glance rather than read a dashboard like a spreadsheet.

That means thinking about size, contrast, page structure, alerts, and what actually deserves space in the driver’s immediate field of view.

The VANDAL DSP was developed around this principle, placing critical vehicle data directly within the driver’s natural field of view.

Software should support the hardware.

Configuration matters because different cars, drivers, and racing environments need different information.

Where VANDAL hardware integrates CANchecked technology, CANchecked serves as our firmware partner and configuration is handled through the CANchecked App.

The purpose of that software layer is not to make the interface feel complicated; it is to let the physical controls and display be configured around the application.

The technology should adapt to the driver, not the other way around.

Design disappears when it works.

The highest compliment for a racing interface may be that the driver stops noticing it.

Controls fall naturally under the fingers. Information appears where expected. Inputs behave consistently. Nothing requires unnecessary thought.

That is driver-centered engineering.
