摘要： Methods and systems for dynamically providing content complementary to a content being rendered on mobile devices based on determining a context of the device based on identifying an encoded unique audio identifier. The transmission and playback of the complementary content is synchronized with the currently rendered content by dynamically taking into account the context of a user operating the mobile device. The context of a user may be built from considering a piece of currently rendered content, characteristics of a profile of a vendor, characteristics of the individual user and/or the user's individual profile, date, time of day and/or further additional information. The context may further take into account the current position and/or location of the user as acoustically triangulated based on sending and/or receiving unique audio identifiers as a high frequency audio signal.

摘要： The present disclosure describes an efficient computer-implemented near-field communication system and method based on broadcasting audio signals for dynamically providing context-related additional content to a mobile device. In embodiments of the present invention, the additional content is mapped to specific audio watermarks and/or triggering commands which are encoded together into a digital signal. Based on continuously scanning the received background noise, an exactly defined frequency range and volume is dynamically selected for broadcasting the signal. Hence, the encoded digital signal is further modulated into an audio signal in the exactly defined frequency range. In embodiments of the present invention, the selected exactly defined frequency range for transmitting the audio signal may preferably be located in the ultrasound and/or infrasound frequency range. In case of transmitting infrasound signals, gyrosensors of the mobile device may be employed as audio signal receivers in embodiments of the present invention. Moreover, in further embodiments of the present invention, audio signal receiver of a mobile device such as gyrosensors or microphones may be switched on by transmitting a command via a wireless network such as Wifi or Bluetooth. Also the information about the selected frequency range and volume for broadcasting the audio signal may be provided to the mobile device via a wireless network in embodiments of the present invention. In response, an audio signal receiver of the mobile device may be tuned to the selected frequency range. The received audio signal is further processed on the mobile device so that the context-related additional content may be displayed and/or rendered.
