Abstract:

Usability evaluation is an important technology used to ensure the interface quality. We use rough grey relation analysis to quantize the fuzziness question of UI evaluation and build an evaluation model of UI.We propose a new method and an experimental paradigm to valuate complex UIs by resolving a complex interface into multiple subinterfaces.The new assessment model and method are applied for objective assessment.Experimental results show that this method can be used for UI evaluation and optimization of multiple complex UIs,and its validity is proved by ERP experiments.
