User Interface for metal detectors

Intuitive user interface

The metal detector INTUITY by Sesotec GmbH is employed in the field of food industry. It guarantees with a high accuracy the detection of magnetic and nonmagnetic metals. Hereby the quality of the final product is secured and the damaging of machines can be avoided. The graphical visualization of the products being detected shows in real-time if metals are found.

The user interface INTUITY CONTROL developed by defortec. INTUITY CONTROL features a new and self-explanatory handling. The lightly and friendly appearance refers to the corporate design of the company Sesotec.

Logic of handling and structure

At first the whole logic of handling of the existing user interface was analyzed by flow charts. In cooperation with Sesotec innovative ideas were formed and a new design of an improved user interface was generated.


Beside the intuitive logic of handling the whole icons of INTUITY CONTROL were developed. The new icons have a self-explanatory character without disregarding already learned symbols and structures. There exist three states of buttons to give the user a clearly feedback: active, pushed and non-active buttons.


The interaction of a coherent corporate design, new developed functions and an innovative logic of handling are decisive for a new benchmark in the market sector of metal detectors.

"User interface design"

Design and functional development of a user interface. Interface is a part or an act, in which a person makes contact with a machine or a product. The simplest example therefore is a light-switch: it‘s not part of the person, neither part of the machine (light), but an interface between. For being useful and important for persons, the interface should be based on human needs and skills. If you look at it systematically user interface belongs to the „Man Machine System“ (MMS): Man  ↔ Man-Machine-Interface ↔ Machine. Different sciences are focused on that theme, e.g. informatics, the Cognitive Science research and psychology. The basic knowledge for user-friendly interface design is developed in design and ergonomics. The specific field of activity is Cognitive Ergonomics, System Ergonomics and Software Ergonomics (usability engineering).
