摘要： Coarse location estimation for mobile devices is disclosed for detecting mobile device presence at general locations of interest and switching operating modes and services for one or more location context aware applications. In some implementations, sensor data is received from a plurality of data sources at a location. For each data source, a first probability is estimated that the mobile device is at the location based on sensor data from the data sources. A second probability is estimated that the mobile device is not at the location based on sensor data from the data sources. The first and second estimated probabilities are statistically combined to generate a third estimated probability that the mobile device is at the location.

摘要翻译： 公开了用于移动设备的粗位置估计，用于检测感兴趣的一般位置处的移动设备存在以及用于一个或多个位置上下文感知应用的切换操作模式和服务。 在一些实现中，在一个位置从多个数据源接收传感器数据。 对于每个数据源，估计基于来自数据源的传感器数据的移动设备处于该位置的第一概率。 估计基于来自数据源的传感器数据的移动设备不在该位置的第二概率。 第一和第二估计概率被统计组合以产生移动设备在该位置的第三估计概率。
