This driving simulator study extended knowledge on user experience using a strategy to mitigate distraction resulting from the use of in-vehicle information systems (IVISs). It examined the impact of system restrictions on users' needs, emotions and consequences of users' experience in terms of psychological reactance. In a repeated measures design, we asked 53 participants to perform secondary tasks with an IVIS while driving. Three versions of the system varied with respect to the number of operable functionalities. The more functionalities that were disabled while driving, the more negatively users rated the systems. Multilevel regression analyses of at least n = 155 data points revealed that drivers' need fulfilment predicted their emotions. Reactance depended on users' need fulfilment and emotions. Experienced autonomy mediated the relation between functional limitations and reactance. When developing interactive systems, one should focus on needs and be aware of potential unwanted consequences such as psychological reactance. Practitioner Summary: This driving simulator study highlights the importance of considering need fulfilment and users' emotions when developing an interactive system that provides high user experience. System restrictions could have negative consequences as users might show psychological reactance.
这项驾驶模拟器研究通过采用一种策略来减轻因使用车载信息系统（IVIS）而产生的干扰，从而扩展了关于用户体验的知识。它从心理抗拒的角度研究了系统限制对用户需求、情绪以及用户体验后果的影响。在一项重复测量设计中，我们让53名参与者在驾驶时使用IVIS执行次要任务。系统的三个版本在可操作功能的数量上有所不同。驾驶时禁用的功能越多，用户对系统的评价就越负面。对至少n = 155个数据点进行的多水平回归分析表明，驾驶员的需求满足情况可以预测他们的情绪。抗拒取决于用户的需求满足情况和情绪。体验到的自主性在功能限制和抗拒之间起中介作用。在开发交互式系统时，应该关注需求，并意识到潜在的不良后果，如心理抗拒。从业者总结：这项驾驶模拟器研究强调了在开发提供高用户体验的交互式系统时，考虑需求满足和用户情绪的重要性。系统限制可能会产生负面后果，因为用户可能会表现出心理抗拒。
