The digital human-machine interaction – the experience of how to operate a machine and how to receive relevant information is one of the biggest challenges in the area of customer satisfaction. User Interface Design and User Experience Design (UI/UX Design) are both design disciplines, which have to be considered carfully when user centric thinking plays a key role. Designing a holistic user experience, it is particularly important to us to ensure that both – product design and user interface design – merge seamlessly into one another. It is about making processes visible and understandable in an aesthetically pleasing way, not only making operation easier, but also making it a joyful experience. We develop UI/UX design as an integral part of smart products or as Apps for smartphones or tablets.
