Together with our customers Eschweiler we have achieved a remarkable paradigm shift in the quality of the user experience of blood analyzers. Equipped with a color touch display the CombiLine III invites to interact in the same manner as we operate with a smartphones. The new concept of the user experience together with a very attractive visual user interface, makes a user manual obsolete. The quality of the graphical user interface characterize three important aspects: One large, clear, visually very tidy structure, the use of color as interactional conductive moment and an icon language that is highly aesthetically developed. Particularly I like to emphasize how holistically the interaction between product - and interface design is. For example if you open a control flap that service instructions are automatically brought up on the display.
