Summary
This study investigates how different information presentation methods influence drivers’ understanding, acceptance, and behavioral intentions regarding advanced driver assistance systems (ADAS) and self-driving vehicles. Motivated by evidence that drivers often possess limited or inaccurate knowledge of in-vehicle technologies due to inadequate consumer education, the research aims to determine which training formats—video, text-only, or text with images—are most effective. The study also examines whether individual characteristics, such as age and baseline technology attitudes, affect acceptance and whether these findings generalize beyond the automotive domain. The researchers conducted an online experiment with 1,238 U.S. adults holding valid driver’s licenses. Participants were randomly assigned to one of three presentation conditions: video-based, text-only, or text with accompanying images. Each group received descriptions of six ADAS examples, including backover prevention and adaptive cruise control. Data collection involved pre- and post-intervention questionnaires measuring baseline technology experience, objective recall of information, perceived ease of understanding, and technology acceptance factors based on the Technology Acceptance Model (perceived usefulness, ease of use, preference, trust, and behavioral intentions). To test generalizability, the experiment included replications in health management and financial technology domains. Results indicated that providing information significantly increased participants’ willingness to try a self-driving car. Video-based presentations were objectively superior for learning; participants in this group demonstrated significantly higher recall accuracy and perceived the information as easier to understand compared to those in text-only or text-with-image groups. While statistical differences in acceptance measures (such as trust or purchase intent) were largely insignificant across methods, a consistent trend showed that the text-only condition yielded the lowest acceptance scores. Conversely, video presentations tended to produce the highest acceptance levels. Correlation analyses revealed that all acceptance factors were strongly interrelated and positively associated with willingness to adopt self-driving technology. Additionally, older participants showed lower baseline technology confidence and lower acceptance of ADAS and self-driving cars, though they performed better in objective recall tasks. The significance of these findings lies in the demonstration that targeted information delivery can enhance public acceptance of autonomous vehicle technologies. The study highlights video as the most effective medium for ensuring comprehension and fostering positive attitudes, suggesting that automakers and policymakers should prioritize multimedia educational materials over text-based instructions. The replication in health and finance domains confirmed that the relationship between information presentation and acceptance is a broader phenomenon, though domain-specific factors like brand recognition may influence the relative effectiveness of different media. Ultimately, the research underscores the importance of addressing the knowledge gap among drivers to maximize the safety and utility benefits of advanced automotive technologies.
Key finding
Video-based information presentations resulted in significantly higher objective recall and perceived ease of understanding compared to text-only or text-with-images formats, while all methods significantly increased willingness to try a self-driving car.
