不久，自动驾驶汽车有望普及，但目前，人们手动驾驶汽车仍很常见。驾驶支持代理（DSA）是用来支持驾驶使用的人-代理交互的方法。在以前的研究中，它表明，DSA可以是有用的，通过语音话语来帮助用户。然而，以往的研究集中在DSA话语设计没有比较记录外的策略与其他礼貌策略，明确沟通说话人的意图，它是不清楚的DSA是否应该提供明确的话语给用户。因此，本研究采用了一个基于视频的主观评价实验（n=240）来比较非记录策略、积极礼貌策略、消极礼貌策略和无礼貌策略的直接话语的可接受性。实验结果表明，在与功能性相关的评价项目上，消极礼貌策略的评价显著高于非正式礼貌策略。这一结果表明，当DSA向用户提供驾驶辅助时，提供具有语言考虑（礼貌）的明确指示是有用的。除了上述发现之外，用户的个性特征与DSA的主观评价之间存在若干相关性。具体而言，用户的谨慎程度与直接话语评价值之间存在显著的正相关。在积极礼貌策略和非正式礼貌策略中，不受欢迎程度的评价类别与用户的人格特征之间没有显著相关。这些结果表明，在积极礼貌策略和非正式策略中，由于人格特征引起的消极印象的个体差异很小。
Soon, autonomous cars are expected to become widespread, but at present, it is still common for people to drive cars manually. A driving support agent (DSA) is used to support driving using the human-agent interaction approach. In previous research, it was shown that DSAs can be useful in assisting the user through voice utterances. However, previous studies focusing on DSA utterance design have not compared off-record strategies with other politeness strategies that explicitly communicate the speaker's intentions, and it was not clear whether DSA should provide explicit utterances to the user. Therefore, in this study, a video-based subjective evaluation experiment (n=240) was conducted to compare the acceptability of off-record strategies, positive politeness strategies, negative politeness strategies, and direct utterances without politeness strategies. The results of the experiment showed that the negative politeness strategy was evaluated significantly higher than the off-record strategy on evaluation items related to functionality. This result suggests the usefulness of providing explicit instructions with linguistic consideration (politeness) when DSA provides driving assistance to users. In addition to the above findings, there were several correlations between the user's personality characteristics and the subjective evaluation of the DSA. Specifically, there was a significant positive correlation between the level of conscientiousness of the user and the direct utterance evaluation value. For the positive politeness strategy and off-record strategy, there were no significant correlations between evaluation categories of the dislikeability and users' personality characteristics. These results suggest that individual differences in n egative impressions due to personality characteristics are small in the positive politeness and off-record strategies.
