| Abstract: |
| 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. |
