Study on Human-machine Interface Design of Rotary Drilling Rigs

In response to the irrational design of various module elements in the digital display interface of rotary drilling rigs, ergonomic design principles such as consistency principle, information visual feature organization principle, information encoding principle, and color perception principle were considered, and the human-machine interface of rotary drilling rigs was improved by combining the actual requirements of information presentation and functional module design. A two-factor [display interface (before and after the improvement) × task type (five functional modules)] intragroup experiment was designed. The usability and cognitive load of the improved interface were validated and evaluated by measuring the physical parameters of eye movement, the operating time, and the subjective questionnaire score. As revealed by the study results, the improved human-machine interface of rotary drilling rigs exhibits higher usability and lower cognitive load. This study provides a reference for the reasonable layout and design of the human-machine interface of complex construction machinery.
