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.

Our competence portfolio

Requirements analysis and competitor research
User-centered development of rough concept and detailed concept, incl. design system
Variant presentation of suitable interaction modalities
Graphics and text (UX writing)
Creation of specifications
Verification

Prototyping

Bertrandt user interface prototyping for early tangibility and well-founded concept decisions:

Simulative representation in software: low- & high-fidelity
Individual models: subsystems, table-top superstructures, driving simulators, real vehicles
Overall experiences from HMI, ergonomics and design
Basis for immersive usability testing
Stand-alone operation, in test environments, in driving simulators - on site or worldwide for your key markets

User Research

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

Preparation, implementation and evaluation of user studies
Acquisition of test subjects (also with own pool of test subjects)
Surveys, interviews, focus groups, driving simulation, real driving..
Standardized procedures such as cognitive walkthrough, studies on driver distraction (NHTSA, AAM)
Individual setups, development & creation of customized methods and measurement technology
Usability and safety-in-use

Implementation

Bertrandt as a partner for the 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 (Protopie, Unity, KANZI, Unreal, QT)
Creation of "pixelperfect" graphics
Performance defense and color/contrast adjustments
Coordination of function and milestone planning, error correction process, requirements analysis

Verification

Bertrandt Verification, conscientious validation of your systems from planning to release recommendation:

Validation of all modalities in the HMI
Certified testers and test managers, independent approach along the test process (ISTQB)
From test planning and control to execution
Automated and manual testing
On the test rack and in the vehicle, also in shift operation if required
Analyzing test results and deriving recommendations for action
Support of the error correction process
