HMI/UX Development

Digitalization has radically changed the interface between humans and machines. We now operate and control more and more products in different ways. While touch displays have become a common feature of everyday life, interaction using natural language as well as gestures and facial expressions opens up completely new opportunities for designing a human-machine interface.

The human-machine interface forms precisely this link between human beings and technology and has the function or transferring information and commands using different operating modalities. Whether they need to operate a washing machine, a vehicle, or even an industrial process control system, users today are continually confronted with new tasks.

Flexible and user-friendly control elements help to successfully master this complexity. The key task of an HMI is to facilitate communication between humans and machines. In order to develop a user-friendly human-machine interface, it is crucial to consistently place the user at the centre of the development process.

For that reason, user-centered design has been at the core of the HMI development process at Bertrandt right from the beginning.

From the development of the initial concept right through to series-production support and further development – our services cover the entire process.

UI/UX

Many years of interdisciplinary design experience for the individual interface of your product:

Systematic approach based on the user-centered design process
Detailed concept specification
Design
Pixel perfect graphics
Text management and translation
Creation of specifications
Transfer to the final product

Bertrandt User Interface Design: the optimum balance between design and functionality.

Prototyping

The concept status that can be experienced early on is the basis for your further decisions:

Simulative representation in software for quick management decisions
Low-fidelity and mature high-fidelity prototypes
Individual hardware models as subsystems or table-top superstructures through to real vehicles or driving simulators
Implementation of a functional overall experience consisting of HMI, ergonomics and design
The ideal basis for immersive usability testing
Stand-alone operation or in test environments or driving simulators - at your premises or worldwide for your key markets

Bertrandt User Interface Prototyping: early tangibility for well-founded concept decisions.

User Research

What do your customers want? We'll find out!

Preparation, implementation and evaluation of user studies
Acquisition of test subjects (also with own pool of test subjects)
Online surveys, interviews, focus groups, driving simulation, real driving...
Standardized procedures such as lane change, driver distraction studies (AAM, NHTSA)
Individual setups as well as development and creation of customized methods and measurement technology (e.g. hardware for recording specific data, eye tracking, physiology)

Bertrandt User Research: A variety of methods for your questions.

Implementation

Conversion of concepts into executable program code:

Implementation on the target
Apps for smartphones (Android, iOS) and wearables
Use of established tools and in-house developments: flexible toolchain from Protopie to Unity, KANZI and Unreal to QT
Creation of "pixel perfect" graphics
Coordination of function and milestone planning, error correction process, requirements analyses
Performance defense & color/contrast adjustments

Bertrandt implementation: we bring your concepts to the target.

Verification

We manage the protection of your systems from planning to release recommendation:

Safeguarding all modalities in the HMI
Certified testers & test managers, independent approach along the test process (ISTQB)
From test planning & control to implementation
Automated and manual testing
On the test track and in the vehicle, also in shift operation if required
Analysis of test results & derivation of recommendations for action
Support of the error correction process

Bertrandt verification: conscientious validation of your products.
