The internal relationship between eye movement characteristics and control tasks

To explore the intrinsic relationship between the controller's eye movement features and the control tasks and to compare the sensitivity of different modes which can reflect different difficulty of the control tasks,the intrinsic link between the eye movement indicators and regulatory tasks and the sensitivity of the difficulty of different tasks on reflecting the task difficulty were explored in this paper through experimental design and clustering results.The difference of task difficulty among the subjects under different task difficulty,instructions number,instruction types and related eye movement indicators in the process of control clustering were categorized.The results showed that the eye movement index was more sensitive to the change of task difficulty,and the eye movement index had a one-to-one correspondence with the type of instruction issued by the subjects.By dynamically linking of the eye movement index and the instruction type,the change of different task's difficulty can be more clearly and accurately reflected.
