    • In general, techniques are described for locating a user using an ultrasound mesh. The techniques may be performed by an interactive system comprising one or more processors. The processors may be configured to determine an amplitude of a first ultrasound signal emitted by one or more transducers and received by a microphone. This first ultrasound signal may be of a first frequency. The processors may then determine an amplitude of a second ultrasound signal emitted by the one or more transducers and received by the microphone. The second ultrasound signal may be of a second frequency different from the first frequency. The processors may be further configured to determine a location of the microphone relative to the one or more transducers based at least on the determined amplitude of the first ultrasound signal and the determined amplitude of the second ultrasound signal.
    • 通常,描述了使用超声波网格定位用户的技术。 这些技术可以由包括一个或多个处理器的交互式系统来执行。 处理器可以被配置为确定由一个或多个换能器发射并由麦克风接收的第一超声信号的幅度。 该第一超声信号可以是第一频率。 处理器然后可以确定由一个或多个换能器发射并由麦克风接收的第二超声信号的幅度。 第二超声信号可以是与第一频率不同的第二频率。 处理器还可以被配置为至少基于所确定的第一超声信号的幅度和确定的第二超声信号的幅度来确定麦克风相对于一个或多个换能器的位置。

    • Systems and methods for determining location based on audio fingerprinting are disclosed. An extraction component extracts a set of interest points from an audio signal associated with an audio announcement. Then a matching component determines if the extracted set of interest points matches a set of interest points representative of an audio fingerprint in a data store comprising audio fingerprints. In an aspect, the audio fingerprints in the audio fingerprint data store represent announcements for underground transportation systems. A location component further determines location information associated with the audio fingerprint based in part on the set of extracted interest points matching the set of audio interest points representative of the audio fingerprint in the data store.
    • 公开了基于音频指纹识别位置的系统和方法。 提取组件从与音频通知相关联的音频信号中提取一组感兴趣点。 然后,匹配组件确定所提取的感兴趣组是否与包括音频指纹的数据存储器中的表示音频指纹的一组感兴趣点匹配。 在一方面,音频指纹数据存储器中的音频指纹代表地下运输系统的公告。 位置组件还部分地基于与代表数据存储器中的音频指纹的音频兴趣点集合匹配的提取的兴趣点集合来确定与音频指纹相关联的位置信息。
