Eye tracking evaluation of human-machine interface layout based on Vague set

In order to realize accurate and objective evaluation of human-machine interface layout, an eye tracking evaluation method of human-machine interface layout based on Vague sets was proposed. First of all, four parameters including track, point of fixation, fixation time, and pupil diameter were taken to build the evaluation index system of human-machine interface layout. Then, on the one hand, the qualitative indexes were transformed into Vague values by uncertain linguistic evaluation form; on the other hand, based on the optimal matrix to obtain the support, oppose and neutral index sets of the layout schemes, the quantitative index would be expressed as Vague values, the Vague set evaluation matrix was built. Finally, the evaluation method based on the distance of Vague values and the optimal and inferior point method were put forward to sort the human-machine interface layout schemes. By taking the human-machine interface layout scheme evaluation of driller console on drilling rig as an example, the practicability and validity of the proposed method was verified.
