Abstract

Smartphones have become ubiquitous in recent years and offer many useful services to their users, such as notifications about incoming calls and messages, or news updates in real-time. These notifications however do not consider the current user's and phone's context. As a result, they can disturb users in important meetings or remain unnoticed in noisy environment. In this paper, we therefore propose an approach to infer the phone's context based on its vibration motor. To this end, we trigger the phone's vibration motor for short time periods and measure the response of its environments using the built-in microphone and/or accelerometers.Our evaluation shows that leveraging accelerometers allows to recognize the current phone's context with an accuracy of more than 99%. As a result, our proposed solution outperforms our previous work based on played and recorded ringtones in terms of classification performance, user annoyance, as well as potential privacy threats.
基于收集环境对振动电机驱动的响应来推断智能手机的位置
近年来,智能手机变得无处不在,并为用户提供了许多有用的服务,例如来电和消息通知,或实时新闻更新。然而,这些通知并不考虑当前用户和手机的上下文。因此,它们可能会在重要会议中打扰用户,或者在嘈杂的环境中不被注意。因此,在本文中,我们提出了一种基于手机振动电机来推断手机上下文的方法。为此,我们在短时间内触发手机的振动马达,并使用内置麦克风和/或加速度计测量其环境的响应。我们的评估表明,利用加速度计可以识别当前手机的上下文,准确率超过99%。因此,我们提出的解决方案在分类性能、用户烦恼以及潜在的隐私威胁方面优于我们之前基于播放和录制铃声的工作。
