摘要:

目的 解决手机—汽车互联产品用户体验评价缺少客观定量数据支撑的问题。方法 提出一种基于用户客观数据的产品用户体验评价方法。以长安汽车手机—汽车互联产品为测评对象，招募20名产品目标用户，使用头戴式眼动仪、面部表情分析系统、手指操作轨迹跟踪分析系统和心理量表，采集用户在完成任务过程中的眼动数据、面部表情数据、手指运动数据以及主观评价值。通过单因素方差分析筛选出与主观评价值相关的客观指标，建立基于客观数据的用户体验评价的回归方程。结论 通过对同类产品的用户体验测评试验对该方法进行验证，模型的准确率为0.886，用户的眼动、表情与手指行为等数据能够客观的反应出产品用户体验的优劣。

Abstract:

It aims to solve the problem of that there is lacking of user objective and quantitative data support for the evaluation of user experience towards phone-vehicle interconnect product. A method of user experience evaluation based on objective data is proposed. The phone-vehicle interconnect product which designed by Changan automobile is used as the evaluation object. 20 target users of the product were recruited. The eye tracker, face reader analysis system, finger motion tracking analysis system and psychological scale are applied to collect the data of users’ eye movement, facial expressions, finger behavior and subjective evaluation during the process of completing tasks. Single factor analysis of variance is used to screen out the objective indexes related to subjective evaluation，then, the user experience evaluation model based on objective data is established. The feasibility of the model is verified through a user experience test of phone-car interconnect product, the accuracy of the model is 0.886. The user's eye movement, facial expression and finger behavior data can reaction out the quality of the user experience of phone-car interconnect products objectively.
