    • A method and system for tracking an activity is described. A location tracking engine tracks a user's location, determines a direction by identifying a plurality of angles ahead of the current location on the path, and conveys navigation information to the user. A filter module receives a location update from a location tracking engine. The filter module performs at least one test on the location update. The filter module adds the location update to a queue of recently received location updates in response to passing the test. The stop detector module determines that the user is stopped and sets the current status to stopped and sets a time of a stop detection change to the later of the last time that of the stop detection change and a timestamp of the oldest location update in the queue if a previous status is moving.
    • 描述了用于跟踪活动的方法和系统。 位置跟踪引擎跟踪用户的位置,通过识别路径上的当前位置之前的多个角度来确定方向,并将导航信息传送给用户。 过滤器模块从位置跟踪引擎接收位置更新。 过滤器模块至少对位置更新进行一次测试。 过滤器模块将位置更新添加到最近接收的位置更新的队列中,以响应通过测试。 停止检测器模块确定用户停止并将当前状态设置为停止,并将停止检测更改的时间设置为停止检测更改的最后一次以及队列中最旧位置更新的时间戳 如果以前的状态正在移动。
