Utilize Eye Tracking Technique To Supplement Traditional User Interface Usability Evaluation Method

Traditional usability evaluation methods of mobile phone interface uses task accomplishing efficiency and error rate to evaluate design effectiveness, and uses conducting time and conducting route to evaluate design efficiencies, and to use subjective judgment to evaluate users’degree of satisfaction. But this type of method has its restrictions for it cannot reveal the users’thinking process, psychological model as well as time, space information in users’searching and processing period when they are interacting with the interface. These data can be utilized by designers to optimize the UI design. On the other hand, Eye Tracking technique can uncover users’eye movements and their psychological models, thus making it meaningful for Eye Tracking Method to supplement traditional usability evaluation methods.This research is based on the combination of Eye Tracking Method and Usability Test, one of the traditional usability evaluation methods, so as to avoid the restrictions of Usability Test. This paper combines these two ways of usability evaluation, integrates two types of evaluation criteria and then conducts twice usability evaluation on the mobile phone interface, thus making sure the usability issues are typical and verify the effectiveness of optimization design.The integration of Eye Tracking Method and traditional usability evaluation method can optimize the system of usability evaluation and make the result more objective and effective. This method is a creative innovative in the usability research domain. It reduces the restrictions of the two while takes advantages of the two, and then make the analysis more convincing, which can provide more diverse data for revealing usability issues and more deep insights for User Centered Design.
