语音助手 (VA) – 如 Amazon Alexa 或 Siri – 提供免提/免眼交互，这有利于一系列用户（包括盲人）完成原本困难或无法完成的任务。虽然这些接口对会话交互进行建模以实现简单的任务，但最近有人呼吁 VA 为更广泛的复杂活动建模更多的事务交互。在这项研究中，我们通过盲人和视力正常的机场旅客的混合能力焦点小组，探索了 VA 在室内导航背景下的能力扩展。我们发现盲人和视力正常的旅行者所遇到的困难高度重叠，并且对语音激活旅行助手以改善旅行体验有着共同的兴趣。利用用户提出的建议，我们提出了交互设计示例，展示了不同和多种模式的定制，这些示例共同展示了虚拟助理如何在复杂的任务场景中更广泛地实现事务交互。
Voice assistants (VAs) – like Amazon Alexa or Siri – offer hands-/eyes-free interactions that are beneficial to a range of users, including individuals who are blind, to fulfill tasks that are otherwise difficult or inaccessible. While these interfaces model conversational interactions to achieve simple tasks, there have been recent calls for VAs that model more transactional interactions for a wider range of complex activities. In this study, we explored the extension of VAs’ capabilities in the context of indoor navigation through mixed-ability focus groups with blind and sighted airport travelers. We found high overlap in the difficulties encountered by blind and sighted travelers, as well as shared interest in a voice-activated travel assistant to improve travel experiences. Leveraging user-elicited recommendations, we present interaction design examples that showcase customization of different and multiple modalities, which collectively demonstrate how VAs can more broadly achieve transactional interactions in complex task scenarios.
