Nowadays, the studies on interface and cognition-engineering has become issues of general interest as newly design-methods which analyze the behavior of user on products. However existing studies were mainly done with verbal-centered method which made it difficult for the designer to apply for visual realization. Moreover many mistakes and noises are taken place whenever the designer converts verbal statements and needs of user into visual factors. Therefore the designer needs to analyze visual perception on user and product as visual-centered methods. This study applies the eye tracking method as analysing-instrument and aims to develop the analysis-framework, the concrete techniques of measurement and the application for the product design. At first the nature and the process of visual perception on products are reviewed for developing analysis method. Then the technique of eye tracking and the meaning of fixation and movement are discussed to specify the concrete method. The basic experiment of product can reveal general analysis process, advantage and guideline for the application of eye tracking method. The Study is peformed through the following 4 steps ; to pre-research into product design and visual perception theory ; to identify the concrete experiment method, to measure the fixation/movement data and analyze the raw data, to convert the result of analysis to the visual framework. Finally the major findings and the limits of the study are suggested and summarized.
