基于用户偏好对比的智能车载交互质量评价方法

目的解决智能车载系统评价缺乏针对性、指标权重确定缺乏客观依据、被试对主观问卷理解存在偏差和评分主观性强等问题,提高智能车载系统可用性。方法分析人机交互质量对用户偏好影响机理,建立智能车载系统客观评价指标体系,并运用三角模糊数构建客观评价模型,然后招募30名被试对手机导航和车载导航对比实验,通过客观评价指标数据确定客观评价指标权重由此评价两款产品交互质量,并对所建立模型进行验证。结果分析实验结果表明手机导航的交互设计质量更高。结论本文所述基于偏好的智能车载系统客观评价模型可用于智能车载系统可用性评价,对产品的开发和优化具有指导意义,并为人机界面设计评价体系提供了实践方法和理论体系。

Interaction Quality of Intelligent In-vehicle System Based on User Preference

The paper aims to solve problems such as usability standard is not targeted for interactive evaluation, index weight determination lacks of objective basis and subjects might distort the meaning of questionnaire, so as to improve the usability of intelligent in-vehicle system. The mechanism of user preferences for human-computer interface quality was analyzed. Then, an objective evaluation index system of intelligent in-vehicle system was constructed. And an objective evaluation model of intelligent in-vehicle system was established. Thirty subjects were recruited to set destination using smartphone and in-vehicle information system respectively. Indexes'' weights were determined by the experimental data, and the interactive quality of intelligent in-vehicle system was quantified by this model. By analyzing the data, it was found that interaction quality of smartphone was better than that of the intelligent in-vehicle system. The objective assessment model for preference based in-vehicle systems can be used to assess the usability of intelligent in-vehicle system. It is meaningful for the development and optimization of intelligent in-vehicle systems. It also provides practical method and theoretical system for evaluation system of human-computer interface design.
