HMI/UX Development

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

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
