全自动驾驶汽车是一项新兴技术，对于那些以前因无法操作传统汽车而处于不利地位的视障人士来说，这项技术可能具有巨大的移动潜力。然而，先前的研究表明，这些消费者对这项技术的可及性及其有效互动的能力有很大的担忧。我们介绍了一项准自然主义研究的结果，该研究在公共道路上进行，有20名视障用户，旨在测试自动驾驶车辆的人机界面。这个原型系统ATLAS是在与视障人士合作的参与式研讨会上设计的，目的是满足盲人和低视力用户的体验需求。我们的结果显示，在与原型互动后，参与者对自动驾驶汽车技术的信任增加，对其可能的可用性更有信心，购买意愿增加，对操作失败的恐惧减少。这些发现表明，即使是与模拟的自动驾驶汽车互动，也可能足以减轻人们对这项技术的不信任感，而且现有技术适当结合在一起，在解决类似情况下视障人士的体验需求方面是有希望的解决方案。
Fully autonomous or "self-driving" vehicles are an emerging technology that may hold tremendous mobility potential for individuals who are visually impaired who have been previously disadvantaged by an inability to operate conventional motor vehicles. Prior studies however, have suggested that these consumers have significant concerns regarding the accessibility of this technology and their ability to effectively interact with it. We present the results of a quasi-naturalistic study, conducted on public roads with 20 visually impaired users, designed to test a self-driving vehicle human-machine interface. This prototype system, ATLAS, was designed in participatory workshops in collaboration with visually impaired persons with the intent of satisfying the experiential needs of blind and low vision users. Our results show that following interaction with the prototype, participants expressed an increased trust in self-driving vehicle technology, an increased belief in its likely usability, an increased desire to purchase it and a reduced fear of operational failures. These findings suggest that interaction with even a simulated self-driving vehicle may be sufficient to ameliorate feelings of distrust regarding the technology and that existing technologies, properly combined, are promising solutions in addressing the experiential needs of visually impaired persons in similar contexts.
