When designing a vehicle cockpit, the three disciplines concerning engineers and/or work scientists, designers and psychologists consist of different tasks. The vehicle interface system cockpit with its interface modules based on interface elements, i.e. control elements, can be regarded as work example. If, for example, a control element is considered as element of the module electrical seat adjustment, the following approaches and/or requirements of the three afore-mentioned disciplines can be identified. The engineer arranges the control element within the grab area and designs the shape of the control element in such a way that, with the correct grab type, the comfortable control forces and moments and the correct control movement, the operating element, e.g. the backrest, can be moved as intended. In contrast, the designer deals with the formal design of the control element. For example, how does the control element fit into the entire formal cockpit design? In this design, the proportions, centrings and symmetries are important design rules. Here, the designers very often follow the integrative up to the integral approach. This approach is often opposed to the ergonomic and thus functional design. The psychologist, however, considers the perception-psychological aspects and thus the multimodal requirements for the cockpit design. The information flow is divided in multimodal perception, cognition and behaviour. Due to the fact that the electric seat adjustment during driving is a multimodal operation, this approach must not be neglected. The major problem of this interdisciplinary task is not only the linguistic barrier but also the apparently opposite requirements. Due to ergonomic reasons, it is formally very difficult to integrate a convex shape into the total design and its meaning and, therefore, the sequence of actions are cognitively misunderstood. In order to better control this magic triangle in an all-embracing approach, objective interlinked criteria allowing an early evaluation of the interface module concept are required. By means of the transparent evaluation system, all engineers, designers and psychologists participating in the three disciplines can understand the approach so that mostly subjective and timeconsuming discussions are avoided. The functional and ergonomic part is calculated by means of a usability-factor. Criteria having a formal-factor as a result are used for the formal investigation. Subsequently, the evaluation of the module location in the primary, secondary and tertiary area and the assignment to a multimodal category of the interface element are completed by a psychological evaluation of the perception.
