位置和上下文切换，特别是室内/室外切换，为上层移动的应用提供了必要的和原始的信息。在本文中，我们提出IODetector：一个轻量级的传感服务，它运行在移动的手机上，并检测室内/室外环境中的快速，准确，高效的方式。受能量预算的约束，IODetector主要利用轻量级感测资源，包括光传感器、磁传感器、蜂窝塔信号等。指纹），并且仅使用主流移动的电话所共有的板上传感器。作为一个通用的轻量级服务组件，IODetector使许多基于位置和上下文感知的应用程序受益匪浅。我们在Android移动的手机上对IODetector进行了原型设计，并采用不同的手机型号，在一个月的时间内从19个轨迹（包括84个不同的地方）收集的数据对系统进行了全面评估。我们进一步进行案例研究，我们利用IODetector即时推断GPS的可用性和定位精度在不同的室内/室外环境。
The location and context switching, especially the indoor/outdoor switching, provides essential and primitive information for upper layer mobile applications. In this paper, we present IODetector: a lightweight sensing service which runs on the mobile phone and detects the indoor/outdoor environment in a fast, accurate, and efficient manner. Constrained by the energy budget, IODetector leverages primarily lightweight sensing resources including light sensors, magnetism sensors, celltower signals, etc. For universal applicability, IODetector assumes no prior knowledge (e.g., fingerprints) of the environment and uses only on-board sensors common to mainstream mobile phones. Being a generic and lightweight service component, IODetector greatly benefits many location-based and context-aware applications. We prototype the IODetector on Android mobile phones and evaluate the system comprehensively with data collected from 19 traces which include 84 different places during one month period, employing different phone models. We further perform a case study where we make use of IODetector to instantly infer the GPS availability and localization accuracy in different indoor/outdoor environments.
