Driver's cab 4.0 - Development of a demand-adaptive user interface for agricultural machinery operators


Motivation:
The increasing automation of work processes gives the driver of mobile machinery the opportunity to focus on other activities. In agriculture in particular, work processes are already being automated using a wide range of technology (precision farming, quality control, etc.) so that the driver can simultaneously take care of farm management tasks while working in the field. However, there is a possibility that the driver may be over- or under-challenged, so a system is to be developed at this point that recommends tasks to the driver for processing or hides unimportant information, depending on his current ability to concentrate.

Project goals:
As part of this project, an adaptive human-machine interface (HMI) is being developed with the help of an occupational psychology research approach, which enables the integration of the driver's workplace of an agricultural machine into other processes of everyday farm life through digital networking. The interface adaptation is based on the user's current stress level. For example, the system supports the user in times of stress peaks by suppressing irrelevant information or enables the user to be activated with additional information and tasks in situations of low stress. Meaningful additional tasks should be generated primarily from the area of farm management in the form of tasks from accounting, fleet management, materials management, etc. or the area of personal tasks such as appointment management, answering e-mails, etc.
The distraction-free and ergonomic processing of these tasks is made possible by an augmented reality environment in the style of a virtual office workstation. Information can thus be projected into the field of vision as required and is no longer tied to displays. Various haptic and visual approaches are available to address the HMI.
