ABSTRACT: Usability evaluation is an important method used to ensure the information transmission efficiency of interface. Rough set is used to quantize the fuzziness question of interface usability evaluation, and build an evaluation model of interface usability with rough-set-grey analysis. Then combining with the fighter interface example, this paper expounds the interface usability evaluation method based on the combination of task deconstruction and the behavior performance test. Finally, from the point of cognitive psycho-physiology, the validity of new assessment method has been proved by brain electrophysiology experiment.
