运用感性工学的相关理论和方法评估保温饮水器的形态设计，进而探索得出一种产品形态设计的合理方法。通过眼动追踪设备捕捉被试者观察试验图片时的眼动数据，并利用划分兴趣区的方式分析被试者对于不同产品形态区域的关注度，以及不同产品形态区域对于产品形态设计的影响。结合眼动数据分析和问卷访谈调研两个方面对保温饮水器形态进行设计评价。试验分析得到保温饮水器的外观形态与其杯身的倾斜程度、杯盖的造型、商标的位置存在的关联。在上述产品形态区域中，商标最受到被试者的注意；当商标位于容器下方时其美观程度高于位于上方位置；杯盖的造型设计为带有卡扣、较为复杂精致的结构时，其美观程度复变高于简单的旋盖结构；当保温饮水器身越趋向于垂直时，保温饮水器的美观程度更高。聚焦用户对保温饮水器的视觉认知规律，验证了眼动实验对产品形态设计评估的有效性。“,”The appearance design of thermal-insulated drinking water containers was evaluated based on the theory and method of Kansei engineering, and then a reasonable method for product appearance design was explored. Eye movement data were captured by an eye movement equipment when testees were observing test pictures. The attention of testees to different product morphology regions and the influences of different product morphology regions on the product appearance morphologies were analyzed by using the method of dividing AOI(area of interest). The appearance design of thermal-insulated drinking water containers was evaluated from both eye movement data and questionnaire evaluation. The relationships between the appearance and the inclination of the containers’ body, the shape of the lid and the position of the trademark were obtained. The trademark is the most noticed by the testees. When the trademark is printed on the low area of the containers’ surface, its aesthetic level is higher than that is printed on the high area. When the shape of the cup cover is designed with a snap and a more delicate structure, its aesthetic level is higher than that with a simpler rotating cover structure. When the inclination of a container body tends to be vertical, its aesthetic level is higher. The visual cognition of users to thermal-insulated drinking water containers was highlighted, and the effectiveness of the eye movement test on product appearance design evaluation was verified.
