Usability Evaluation Method Using Biological Data

摘要

Usability has been important factor on the design for the interface of product and system. The current evaluation methods used to assess the usability factors are interview and questionnaires. These are based on the subjective approach, therefore certain limitations are encountered. It is difficult to get the data on usability for a long duration, the quality of evaluation depends on the skill of the evaluator and these evaluation approaches are costly and time-consuming. Then, our research team has been studying the objective usability evaluation methods using biological data, some of which are eye movement and fingertip movement during the operations of the target interface. Based on the analysis of the captured data, the interface design can be sufficiently improved. In the keynote, basic idea and specific experiment of the proposed method will be presented.
