论文摘要
语音助手最近取得了杰出的商业成功。但是，这些设备的当前一代通常只能仅反应性相互作用。换句话说，交互必须由用户启动，这在某种程度上限制了其可用性和用户体验。我们建议，下一代此类设备应该能够在正确的时间以正确的方式主动提供正确的信息，而不会被用户提示。但是，实现这一目标并不简单，因为存在危险，它可能会中断用户的工作太多，从而使其分心甚至令人讨厌。此外，它可能不知不觉地向第三方揭示敏感/私人信息。在本报告中，我们讨论了开发主动启动相互作用的挑战，并为设备进行干预时提出了一个框架。为了验证我们的设计假设，我们首先描述了我们如何构建功能正常的原型，其次，在有主动的语音助手的情况下，进行了用于评估用户的反应和反思的用户研究。该预印刷总结了截至2018年秋天的积极主动设备的状态，思想和进步。
Voice assistants have recently achieved remarkable commercial success. However, the current generation of these devices is typically capable of only reactive interactions. In other words, interactions have to be initiated by the user, which somewhat limits their usability and user experience. We propose, that the next generation of such devices should be able to proactively provide the right information in the right way at the right time, without being prompted by the user. However, achieving this is not straightforward, since there is the danger it could interrupt what the user is doing too much, resulting in it being distracting or even annoying. Furthermore, it could unwittingly, reveal sensitive/private information to third parties. In this report, we discuss the challenges of developing proactively initiated interactions, and suggest a framework for when it is appropriate for the device to intervene. To validate our design assumptions, we describe firstly, how we built a functioning prototype and secondly, a user study that was conducted to assess users' reactions and reflections when in the presence of a proactive voice assistant. This pre-print summarises the state, ideas and progress towards a proactive device as of autumn 2018.
