HMI/UX Development

As a service provider with many years of design and development experience, we cover the entire UI/UX process. From the concept stage, which can be experienced at an early stage, to mature prototypes and the final product: we accompany you on the way to a successful product.

This is what sets us apart:

User centricity
Iterative approach
Consistent safeguarding

Our know-how for your interface!

UI/UX

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

Human Centered Design Process
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
