摘要:

调查促使人类信任自动驾驶汽车(AV)的因素将在采用此类技术方面发挥重要作用。用户形成AV的心理模型的能力,这对于建立信任至关重要,取决于有效的用户-车辆通信;因此,人机交互(HMI)的重要性将增加。在这项工作中,我们提出了一种方法来验证AV的用户体验的基础上收集的生理信号的连续,客观的信息,而用户沉浸在一个虚拟现实为基础的驾驶模拟。我们将这种方法应用于平视显示器界面的设计,提供有关车辆的感官和规划系统的视觉提示。通过这种方法,我们获得了定性和定量的证据表明,一个完整的图片的车辆的周围环境,尽管较高的认知负荷,有利于减少压力的经验。此外,在接触了更多信息的界面后,参与研究的用户也更愿意测试真正的AV。所提出的方法可以通过调整模拟环境、HMI和/或车辆的人工智能模块来扩展,以深入研究用户体验的其他方面。

英文摘要:

The investigation of factors contributing at making humans trust Autonomous Vehicles (AVs) will play a fundamental role in the adoption of such technology. The user's ability to form a mental model of the AV, which is crucial to establish trust, depends on effective user-vehicle communication; thus, the importance of Human-Machine Interaction (HMI) is poised to increase. In this work, we propose a methodology to validate the user experience in AVs based on continuous, objective information gathered from physiological signals, while the user is immersed in a Virtual Reality-based driving simulation. We applied this methodology to the design of a head-up display interface delivering visual cues about the vehicle' sensory and planning systems. Through this approach, we obtained qualitative and quantitative evidence that a complete picture of the vehicle's surrounding, despite the higher cognitive load, is conducive to a less stressful experience. Moreover, after having been exposed to a more informative interface, users involved in the study were also more willing to test a real AV. The proposed methodology could be extended by adjusting the simulation environment, the HMI and/or the vehicle's Artificial Intelligence modules to dig into other aspects of the user experience.
