| Abstract: |
| This paper explores the interactive design strategy of the infographic on radar interface to reduce users’ cognitive load from the perspective of human-machine cognitive task allocation. This paper analyzed the systematic observation task flow of radar infographic, discussed different human-machine allocation methods of system tasks from the perspective of new human-machine coordination and cooperation, collected and analyzed the task completion time, accuracy rate and the cognitive loads through user performance measurement and NASA-TLX scale, and contrasted the impact of different human-machine task allocation methods on users’ cognitive load. In the design based on the new human-machine task allocation, the users’ completion time and accuracy rate were both greater than those in the initial interface design, and the cognitive load to complete the cognitive task was less than that in the initial interface design. Through rational allocation methods of system cognitive tasks between humans and machines, the information presentation and interactive design of complex information interfaces can give full play to the respective advantages of humans and machines, reduce the cognitive load of operators, and improve observation accuracy and system performance. |
