游艇关键造型特征的眼动追踪研究

Eye Tracking on Key Modeling Features of Yachts

目的为建立眼动数据和感性意象评价之间的数学关系,提出一种基于眼动参数的造型评价方法。方法以游艇为研究对象,通过SMIRED500型眼动仪设备的应用,结合语义差分法进行主观评价,通过眼动追踪记录受试者在观看不同造型风格游艇时的眼动数据,对采集的眼动数据进行单因素方差分析,保留瞳孔直径大小、总注视时间、眼跳到该区域次数及首视点持续时间四项有效眼动数据,并结合主观问卷探讨不同游艇的视觉认知规律,采用多元线性回归方程进行数据建模,明确各项眼动数据对感性评价的影响权重,研究了被视者的眼动追踪数据与主观评价之间的关联关系。结论建立眼动数据与感性评价之间的数学关系模型,并验证了模型的有效性,对产品造型方案评选及产品设计方案改进提供了有力的支持。

The work aims to propose a modeling evaluation method based on eye movement parameters to establish a mathematical relationship between eye movement data and perceptual image evaluation.With yacht as the research object,the eye movement data of the subjects watching different styles of yachts was recorded by eye tracking through the application of SMIRED500 eye tracker and combined with semantic difference method for subjective evaluation.The eye movement data was analyzed by one-way analysis of variance to retain the four effective eye movement data of pupil diameter,total fixation time,eye frequency to the region and duration of the first viewpoint and subjective questionnaires were used to explore the visual cognition rules of different yachts.The multivariate linear regression equation was used to model the data,and the influence weight of variouseye movement data on the perceptual evaluation was clarified.The relationship between the eye tracking data and the subjective evaluation of the subject was studied.The mathematical relationship model between eye movement data and perceptual evaluation isestablished,and the validity of the model isverified,providing strong support for product modeling selection and product design improvement.
