基于眼动追踪的陶瓷产品造型设计评价方法

Ceramic Product Modeling Design Evaluation Method Based on Eye Tracking

目的为了提高传统陶瓷产品造型设计评价的有效性,提出一种基于眼动追踪的陶瓷产品造型评价模型。方法为了将用户对陶瓷产品造型的评价量化为数据,使用Tobii Glasses 2眼动仪和其配套软件Tobii Pro Lab,收集二十名被试对四件陶瓷产品造型评价活动中的多项眼动指标数据,并获取被试打分值;以注视总时间、首次注视持续时间、注视点数目、瞳孔直径等指标数据为输入,采用SVM算法,建立以眼动数据为输入,评价值为输出的造型设计评价模型,并使用测试集数据验证及分析模型。结论基于眼动追踪的评价模型具有合理性,有利于充分发挥陶瓷造型设计评价环节的重要作用,为陶瓷产品造型评价提供了新思路。

The work aims to propose a ceramic product modeling evaluation method based on eye tracking,in order to improve the effectiveness of traditional ceramic product modeling design evaluation.In order to quantify the user’s evaluation of ceramic product modeling as data,Tobii glasses 2 eye tracker and its supporting software Tobii Pro lab were used to collect the eye movement index data of twenty subjects in the modeling evaluation activity of four ceramic products and obtain the score of each subject.With total fixation time,first fixation duration,fixation points and pupil size as input,support vector machine(SVM)was used to establish the design evaluation model with eye movement data as input and scoring value as output and the test set data were used to verify and analyze the model.The evaluation model based on eye tracking is reasonable,which is conducive to giving full play to the important role of ceramic modeling design evaluation,and provides a new idea for ceramic product modeling evaluation.
