智能设备和物联网（IoT）技术正在以越来越快的速度取代或融入传统设备。使用数字接口与这些设备进行交互已成为世界各地家庭、工作场所和各种行业的常见现象。这些连接设备的最常见接口集中在移动的应用程序或通过智能虚拟助理进行语音控制。然而，随着增强现实（AR）在消费者中变得越来越流行和可访问，空间用户界面有了新的机会，可以无缝地弥合数字和物理启示之间的差距。在本文中，我们提出了一个人的主题研究评估和比较四个智能连接环境的用户界面：凝视输入，手势，语音输入，和一个移动的应用程序。我们评估了参与者的用户体验，可用性，任务负载，完成时间和偏好。我们的研究结果表明，在这些措施之间的接口多个权衡。特别是，我们发现，与语音输入和移动的应用相比，凝视输入在未来的用例中显示出巨大的潜力，而凝视输入和手势在用户中的熟悉度有限。
Smart devices and Internet of Things (IoT) technologies are replacing or being incorporated into traditional devices at a growing pace. The use of digital interfaces to interact with these devices has become a common occurrence in homes, work spaces, and various industries around the world. The most common interfaces for these connected devices focus on mobile apps or voice control via intelligent virtual assistants. However, with augmented reality (AR) becoming more popular and accessible among consumers, there are new opportunities for spatial user interfaces to seamlessly bridge the gap between digital and physical affordances. In this paper, we present a human-subject study evaluating and comparing four user interfaces for smart connected environments: gaze input, hand gestures, voice input, and a mobile app. We assessed participants’ user experience, usability, task load, completion time, and preferences. Our results show multiple trade-offs between these interfaces across these measures. In particular, we found that gaze input shows great potential for future use cases, while both gaze input and hand gestures suffer from limited familiarity among users, compared to voice input and mobile apps.
