How to develop a HMI for an agricultural tractor focusing on the handling of various implements

Abstract

Mobile machines are used in a variety of work scenarios. One of these machines is the tractor in agricultural use. The agricultural tractor operates with a huge number of different implements. These need to be controlled with just one static human machine interface. Consequently, there is a grand difficulty to get all the different scenarios arranged with one compromise interface system solution which is in charge of the possibility that every implement can be operated with. Thus the need of an adaptive human machine interface (HMI) is the initial situation of this research project, called aISA – adaptive Interface Systems in Agricultural tractors. Based on field measurements with an agricultural tractor, surveys and theoretical analysis a method was generated which enables the development of adaptive interface systems. By the example of the HMI of an agricultural tractor the method will be validated. This paper deals with the analysis and the development of the method which leads to first concepts of an adaptive HMI.
