Objective: This study aims to examine explanation effects on users" subjective responses focusing on a driving style and risk severity in autonomous driving. Background: An autonomous vehicle can distract users" attention to the hazardous situation. Previous researchers have emphasized a feedback system to support situation awareness. However, the negative effects on user experience can be induced from an explanation without both environmental context and users" driving style. Method: The experiment was conducted to explore the effects on users" subjective responses among three factors: explanation type, risk severity, driving style. First, we classified driving styles into aggressive and defensive styles via clustering method. Second, we tested the statistical significance of the three factors. Results: First, aggressive users showed more positive responses when they received only "why" information. Defensive users showed more positive responses when they received both "why" and "how.’ Second, users in the high-risk situation preferred the explanation about ‘why.’ users in the low-risk situation preferred the explanation about both ‘why" and "how.’ Conclusion: According to the results, we conclude an explanation considering users’ driving style and risk severity can increase user experience on the autonomous vehicle. Application: Therefore, this study has an implication to suggest a guideline for a personalized interface on autonomous vehicles.
