A design approach for integration of the HMI to multiple driver systems
The INTEGRATE project tackled the problems that are likely to arise from the introduction of multiple driver systems each generating their own separate driver inputs and system outputs (i.e. high driver workload, impaired usability of systems and subsequent implications for safety and customer acceptance). This paper reports the results of the project, namely a structured human factors design approach for integrated system design. No other such design process has been documented in the publicly available literature, nor within automotive R&D departments in the UK. The content of the process is a response to the industry requirements identified within the project. Each stage of the process contributes to the main activities of: system definition, identification of potential conflicts and their likely impact, and resolution of these conflicts through good human-machine interface (HMI) design. The paper concludes with results of industry consultation on the implications the approach has for current design processes in the automotive industry.
