HMI requirements creation, as the collaboration work of human and machine in the safety-critical system

Abstract

In the safety-critical system, the Human-Machine Interface (HMI) is tightly coupled with system requirements; the functional requirements and the non-functional requirements. As the human has some limitations in his cognitive work, we cannot generate the HMI from the requirements of the complex system in the simplistic way. In this paper, we propose the HMI abstract model from the provisional system requirements, maintaining the simplicity of HMI. We do not intend to create HMI model from the final system requirements but rather traverse the both sides with keeping the safety property. In order to show our idea clearly, we use several examples in the automobile field.
