一句话:提出 VITAS,用引导式基于模型的方法对 VPA 应用的 VUI 进行测试,以应对其不可见、单模态等问题。
虚拟个人助理(VPA)服务(如 Amazon Alexa 和 Google Assistant)日益流行,用户通过语音应用(如 Alexa skills 和 Google Assistant actions)与其交互。与具有可见且直观 GUI 的桌面和移动应用不同,VPA 应用仅通过语音用户界面(VUI)以纯口头方式传递信息;VUI 具有不可见、单模态和对用户注意力要求高等局限,可能导致 VPA 应用在可用性和正确性方面出现多种问题。为应对这些问题,论文提出 VITAS,一种引导式、基于模型的 VUI 测试方法。摘要仅介绍了 VPA/VUI 的背景与测试动机,未给出具体技术或实验结果。
Virtual personal assistant (VPA) services, e.g. Amazon Alexa and Google Assistant, are becoming increasingly popular recently. Users interact with them through voice-based apps, e.g. Amazon Alexa skills and Google Assistant actions. Unlike the desktop and mobile apps which have visible and intuitive graphical user interface (GUI) to facilitate interaction, VPA apps convey information purely verbally through the voice user interface (VUI), which is known to be limited in its invisibility, single mode and high demand of user attention. This may lead to various problems on the usability and correctness of VPA apps.
