多模态交互(MMI)正在被广泛实施,特别是在增强现实(AR)系统等新技术中,因为它被认为支持更自然的,高效,灵活的互动形式。然而,研究了MMI在AR中的正确应用。更具体地说,在AR中MMI期间组合不同输入和输出模式的效果仍未完全理解。因此,本研究旨在研究典型AR任务中不同输入和输出模式的独立和综合效应.20名年轻人参加了一项对照实验,在该实验中,他们被要求使用AR设备在不同的输入(语音,手势,多模态)和输出(VV-VA,VV-NA,NV-VA,NV-NA)条件。结果表明,输入和输出模式对任务绩效的影响存在差异,工作量,感知的适当性,和用户偏好。在这项研究中,输入和输出条件对绩效指标的交互作用也很明显。这表明,尽管多模态输入通常是用户首选的,它应该谨慎实施,因为它的有效性受到系统输出的处理代码的高度影响。这项研究,这是同类中的第一个,揭示了MMI在AR系统中应用的几个新含义。
Multimodal interaction (MMI) is being widely implemented, especially in new technologies such as augmented reality (AR) systems since it is presumed to support a more natural, efficient, and flexible form of interaction. However, limited research has been done to investigate the proper application of MMI in AR. More specifically, the effects of combining different input and output modalities during MMI in AR are still not fully understood. Therefore, this study aims to examine the independent and combined effects of different input and output modalities during a typical AR task. 20 young adults participated in a controlled experiment in which they were asked to perform a simple identification task using an AR device in different input (speech, gesture, multimodal) and output (VV-VA, VV-NA, NV-VA, NV-NA) conditions. Results showed that there were differences in the influence of input and output modalities on task performance, workload, perceived appropriateness, and user preference. Interaction effects between the input and output conditions on the performance metrics were also evident in this study, suggesting that although multimodal input is generally preferred by the users, it should be implemented with caution since its effectiveness is highly influenced by the processing code of the system output. This study, which is the first of its kind, has revealed several new implications regarding the application of MMI in AR systems.
