The impact of individual differences on the acceptance and usability of an in-vehicle information system touchscreen

Examining and verifying the effects of individual differences on the acceptance and usability of in-vehicle information system (IVIS) touchscreens, and exploring whether there is a potential relationship between the two is of great significance for promoting the diversification of in-vehicle human-machine interaction. In the first stage of this study, 277 valid questionnaires were collected to investigate the effects of gender, age, and education level on the acceptability of IVIS touchscreens. Results showed higher acceptance observed among females, middle-aged individuals, and participants with a master's degree or higher. The second phase of the experiment was used to evaluate the static car test of 36 participants to examine the role of gender and age differences in the acceptance of IVIS touchscreens based on their usability dimensions. Results showed that gender significantly affected the perception of usability of IVIS touchscreens, with males being significantly more efficient than females, but females were more satisfied with IVIS touchscreens than males. Regarding gender differences, technology acceptance positively correlates with subjective usability but does not necessarily indicate better objective usability performance. It can be inferred from this that subjective perception is not entirely dominated by usage experience, but may also be affected by individual differences.
