使用移动设备的非常规TV检测
Unconventional TV Detection using Mobile Devices
摘要：
最近的研究表明，电视观看体验正在发生变化，出现了“多屏幕观看”和“连接观众”等趋势。这些趋势描述了在观看电视时使用移动设备（例如平板电脑和智能手机）的电视观众。在本文中，我们利用无处不在的移动设备提供的上下文信息来检测电视的存在和跟踪正在观看的媒体。我们的方法利用现代移动设备中可用的传感器阵列，例如摄像头和麦克风，来检测电视机的位置，它们的状态（打开或关闭）以及它们当前调谐到的频道。我们提出的可行性，建议的传感技术使用我们的Android手机上实现不同的现实场景。我们的研究结果表明，在一个受控的环境中的检测精度为0.978 F-措施可以实现。
英文摘要：
Recent studies show that the TV viewing experience is changing giving the rise of trends like "multi-screen viewing" and "connected viewers". These trends describe TV viewers that use mobile devices (e.g. tablets and smart phones) while watching TV. In this paper, we exploit the context information available from the ubiquitous mobile devices to detect the presence of TVs and track the media being viewed. Our approach leverages the array of sensors available in modern mobile devices, e.g. cameras and microphones, to detect the location of TV sets, their state (ON or OFF), and the channels they are currently tuned to. We present the feasibility of the proposed sensing technique using our implementation on Android phones with different realistic scenarios. Our results show that in a controlled environment a detection accuracy of 0.978 F-measure could be achieved.
