Rolls-Royce Marine is currently developing a semi-autonomous cargo vessel. The semi-autonomous cargo ship operation is a supervisory control task, in which the human operator is receiving information from a remote semi-autonomous vessel and instructing it through supervisory control interfaces. Thus, it is necessary to have supervisory control interfaces to carry the operation. But, the design guidelines for the interfaces are unclear, because of the lack of semi-autonomous cargo ships.
The thesis presents design guidelines for developing supervisory control interfaces for the semi-autonomous cargo vessel. The research question answered in this thesis is: “How to design a supervisory control interface for remote semi-autonomous cargo vessel system to enable intuitive and precise instruction of the course plan?” The author answers the question through a research and design process that consists of the problem and solution spaces.
The problem space suggests design requirements through a literature review and experts interviews. The literature review gives contextual and theoretical knowledge to design supervisory control interfaces. The expert interviews with video gamers and autonomous ship experts present potential user needs and design considerations. The findings from the problem space combine and formulate design requirements.
The solution space ideates and prototypes a supervisory control interface prototype by applying the design requirements. The prototype has been evaluated in usability tests with sailors and autonomous ship expert. The findings from the usability tests are linked to the design requirements to evaluate how the designed solution fulfils design requirements.
The thesis contributes to the design of semi-autonomous cargo vessel supervisory control interfaces by answering to the research question. In the conclusion part, the author answer to the research question by suggesting three design themes, which are synthetics of the design requirements and analysis. The design themes are: providing situation awareness, intuitive manipulation, and collaborative control.
With these design themes designers will be able to develop supervisory control interfaces, which present intuitive and precise course planning capability to the operators. At the same time, the findings of the thesis will provide several directions for further research, such as researching an unmanned surface vehicle supervisory control interface
