Japanese drivers' acceptance investigation of the driver-vehicle interaction system

This descriptive study investigated respondents' acceptance of driver-vehicle interaction systems by modifying the technology acceptance model using user experience concepts. A questionnaire survey including 15 variables was conducted to examine six constructs proposed in the modified technology acceptance model: perceived usefulness, perceived enjoyment, satisfaction, attitude, interactive media, and user interface. 495 samples aged from 21 to 82 years old (48.7 ± 12.5 years) including 279 males and 216 females were collected for data analysis. Confirmatory factor analysis demonstrated the reliability and validity of the model using several indices. Correlations between constructs were proven using path analysis (p < 0.05). Then, the influences of drivers' gender and age on the constructs were analyzed using linear regression analysis. Male drivers had higher perceived usefulness and more positive attitudes than female drivers. However, their perceived enjoyment of the system was lo..., We used a questionnaire survey method to collect respondents' opinions. A questionnaire with 15 variables was designed to present the proposed model, and a Likert scale (1-5) range from ‘strongly agree’ to ‘strongly disagree’ was adopted for all variables.
The ethical committee of the University of Tsukuba approved this study. The approval number is 2021R551-1. Respondents with driving licenses and ages from 20 to 99 can complete the questionnaire., , # Japanese driver's acceptance of driver-vehicle interaction systems

## Description of the data and file structure

We designed a questionnaire with 15 variables. A Likert scale (1-5) ranging from ‘strongly agree’ to ‘strongly disagree’ was adopted to measure all variables. The variables reflect six constructs of a modified technology acceptance model (i.e., PU: perceived usefulness, PE: perceived enjoyment, ST: satisfaction, AT: attitude, IM: interactive media, and UI: user interface. In addition, we collected the respondents' gender and age.

**Description:** 

##### Variables

* Age: Respondents' ages ranged from 21 to 82 years were recorded (Mean = 48.7, Standard deviation = 12.5).
* Gender: coded for Male and female

A Likert scale (1-5) ranging from ‘strongly agree’ to ‘strongly disagree’ was adopted for measuring all of the following variables.
* PU..., This dataset was collected as part of a study approved by the ethical committee of the Institute of System and Information Engineering, University of Tsukuba (Approval No. 2021R551-1). All participants provided informed consent, including consent to share their anonymized responses in the public domain for research purposes.
To ensure de-identification, all personally identifiable information (i.e., educational background and precise geographic locations) was excluded from the dataset. The remaining variables—age, gender, and questionnaire variables on a 5-point Likert scale—do not allow the identification of individuals. Age is represented as a numerical value without any linking identifiers, and gender is included solely for analytical purposes.
