Design Method of Touch Interface Based on Event-Related Potential
The design method of touch interface based on event-related potential is proposed to solve the ergonomic design problems caused by the application of touch screen in civil aircraft cockpit.The visual characteristics of hu-man-machine interface are analyzed.Six touch interfaces are designed from shape and spacing.The experiment is designed based on visual search experimental paradigm.The influence of visual features on performance is explored through event-related potential,response time,accuracy and subjective results.The ergonomics is evaluated based on the fuzzy mathematics method.The experiment finds out that the difference between touch components of different shapes is mainly reflected in P300,and the difference between different spacing is mainly reflected in Nl.Under the condition that the touch components are in the range of spacing 0～3.5 mm,the subjects performed better when the spac-ing is wider.It is feasible to use this method to evaluate the ergonomics of the touch control interface of civil aircraft cockpit.
