Description

BACKGROUND
• Communication with electronic user devices has become a large part of everyday life. For many people, user devices such as mobile telephones, laptops, and tablet computers are an integral part of their life. Also, many people are often recipients of broadcast content provided by television and radio networks, cable companies, internet web sites, and a variety of closed circuit systems. Broadcasters of content typically strive to improve communication with recipients for a wide variety of reasons and use a wide variety of tactics to effect the desired communication improvements. Similarly, recipients of a content broadcast may desire a better content receiving experience. For example, television broadcasters may want to improve viewer reception of advertisements, while viewers may want to receive more highly relevant content from advertisements. Many systems are presently available for optimizing the available communication channels and communication techniques have been implemented by broadcasters of content, however, the current content delivery methods employed in the prior art may be further improved as presently disclosed.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
• The present disclosure relates in general to a communication system and, in particular, to a system, methods, and apparatus for communication using sonic signaling. Briefly, in an example embodiment, a system is provided which transmits a message from a traditional broadcast to a user device using wireless communication. For example, a television wirelessly sends data to a user and a mobile phone using sonic signaling. In one example embodiment, the sonic signaling may include a signal portion that is within a frequency range that is inaudible to a typical human, but can be understood by the mobile phone. It should be appreciated that humans above the age of eight are generally unable to sense sounds above approximately 18 kHz, but microphones in user devices can typically detect frequencies of up to 22.05 kHz or 24 kHz. Also, broadcast device speakers, even cheaper commodity speakers or stock speakers, can typically produce sounds above 20 kHz. Accordingly, the sonic signaling may include an audible portion for humans and an inaudible portion recognizable by machines but not within the normal hearing range of a typical human.
• In an example embodiment, the broadcast device (e.g., a television) may be playing an advertisement which is part of the programming content (e.g., a television show), and the sonic signal broadcast by a speaker includes an audible track, such as music and a voiceover, and an inaudible data signal which is received by a microphone of a user device (e.g., mobile phone). The user hears the audible track and the user device performs an action based on the received inaudible machine signal, such as displaying a text message, providing rewards points to the user, accessing a web page, or storing a coupon. In a preferred embodiment, a machine signal intended for reception at the user device is entirely inaudible to humans. As further discussed below, it should be appreciated that the disclosed sonic signaling communication provides many benefits to content providers and broadcasters of content as well as recipients of broadcasted content.
• A high level block diagram of anexample communication system100 is illustrated inFIG. 1. The illustratedexample communication system100 includes a plurality ofcommunication devices101, including abroadcast content server102, abroadcast device104, auser device106, and auser content server108.

Abroadcast content server102 may be configured according to a particular operating system, application, memory, hardware, transmitter, etc., and may provide various options for managing the execution of broadcasting programs and applications, as well as various administrative tasks.
• Abroadcast device104 may be, for example, a television, a radio or stereo system, a movie theater system, a closed circuit video and/or audio system, a desktop computer, a laptop computer, a tablet computer, a smartphone, etc. Abroadcast device104 typically receives data representing an audio and/or visual broadcast via a signal (e.g., radio frequency signal, cable signal, satellite signal, IPTV signal) or a computer readable medium (e.g., CD, DVD, memory card). Abroadcast device104 broadcasts content for user consumption, typically including video content and/or audio content. For example, a television may display programming images from a network broadcaster or a DVD, while also actuating one or more speakers for an audible portion of the programming. A user110 may watch the visual portion of the programming and listen to the audible portion of the programming. It should be appreciated that abroadcast device104 may include multiple components (e.g., screen, set top box, digital video recorder, speakers), typically connected with wires. It should also be appreciated that data received as a broadcast signal may be temporarily stored on a computer readable medium (e.g., random access memory).
• Auser device106 may be, for example, a mobile device, such as a cellular telephone, a personal digital assistant or PDA, a smartphone, a laptop, a tablet computer, or a desktop computer, as well as any other user devices. Theuser device106 is used by a user110 for any of a wide variety of tasks or functions, including business uses and recreational uses. Theuser device106 typically includes, for example, a display, a speaker, and a microphone. Typically, a microphone would receive voice signals from a user or some other sonic signals which a user would wish to record. Theuser device106 may have a connection to one or more communications channels such as the Internet or some other voice and/or data network, including, but not limited to, any suitable wide area network or local area network.
• Auser content server108 may be, for example, a web server that receives a shortened uniform resource locator (“URL”) and serves a web page to a user110 by processing the shortened URL to return a web page. For example, a customized web page may be provided to a user110 based on identifying information from theuser device106 which allows theuser content server108 to provide a customized experience for the user110. Also, for example, a user content server may generate an email message or SMS text message to the user110. Auser content server108 may be a high end computer with a large storage capacity, one or more fast microprocessors, and one or more high speed network connections. Auser content server108 may be configured according to a particular operating system, application, memory, hardware, network, etc., and may provide various options for managing the execution of programs and applications, as well as various administrative tasks. Auser content server108 typically stores one or more of a plurality of files, programs, databases, and/or web pages in one or more memories for use byuser devices106.
• It should be appreciated that theexample communications system100 is illustrated using a single device for each stage of the communication system, however, the illustrated devices may be representative of a plurality of devices. For example, thecommunications system100 may include a plurality of differentbroadcast content servers102, a plurality ofdifferent broadcast devices104, a plurality of different auser devices106, and/or a plurality of differentuser content servers108. For example, a singlebroadcast content server102 may communicate withmany broadcast devices104, and asingle broadcast device104 may communicate with manybroadcast content servers102 and/ormany user devices106. Likewise, for example, asingle user device106 may communicate withmany broadcast devices104 and/or manyuser content servers108, and a singleuser content server108 may communicate withmany user devices106. Further, for example, abroadcast content server102 and auser content server108 may communicate with each other. In an example embodiment, a single server system may perform the functions of thebroadcast content server102 and theuser content server108.
• A detailed block diagram of the electrical systems of anexample communication device101 is illustrated inFIG. 2. In this example, thecommunication device101 includes amain unit202 which preferably includes one ormore processors204 electrically coupled by an address/data bus206 to one ormore memory devices208,other computer circuitry210, and one ormore interface circuits212. Theprocessor204 may be any suitable processor, such as a microprocessor from the INTEL PENTIUM® family of microprocessors. Thememory208 preferably includes volatile memory and non-volatile memory. Preferably, thememory208 stores a software program that interacts with the other devices in thecommunication system100 as further described below. This program may be executed by theprocessor204 in any suitable manner. Thememory208 may also store digital data indicative of documents, files, programs, web pages, etc. received from acommunication device101.Other computer circuitry210 may include a wide variety of hardware components including ASICs, or other specialized circuitry for manipulating data in a specific format, such as streaming video data.
• Theinterface circuits212 may be implemented using any suitable interface standard and/or protocol including, for example, an ATSC interface, a WiFi interface, a Bluetooth interface, an Ethernet interface and/or a Universal Serial Bus interface. The interface circuits may interact with one ormore communication networks213, as well as one or more local components. It should be appreciated thatmany communication devices101 may have multiple interface channels which may be used simultaneously or alternatively used. One ormore input devices214 may be connected to theinterface circuits212 for entering data and commands into themain unit202. For example, theinput devices214 may be a keypad, keyboard, mouse, touch screen, track pad, track ball, isopoint, remote controller, and/or a voice recognition system.
• One or more speakers, displays, printers, and/orother output devices216 may also be connected to themain unit202 via theinterface circuits212. The speaker may include a single speaker or a multi-speaker system. The display112 may be a liquid crystal display or any other type of display. The speaker and display may generate an audio-visual content for a user110 or administrator during operation of thecommunication devices101. For example, theoutput devices216 may act as a user interface that provides one or more web pages received from acommunication device101. A user interface may also include prompts for human input from a user110 viainput devices214 including links, buttons, tabs, checkboxes, thumbnails, text fields, etc., and may provide various outputs in response to the user inputs, such as still images, videos, audio, animations, and text.
• One ormore storage devices218 may also be connected to themain unit202 via theinterface circuits212. For example, a hard drive, CD drive, DVD drive, and/or other storage devices may be connected to themain unit202. Thestorage devices218 may store any type of data, such as image data, video data, audio data, tagging data, historical access or usage data, statistical data, security data, etc., which may be used by thecommunication device101. Astorage device218 may be manufactured as a mass produced item, be custom generated and/or be modified by acommunication device101.
• Thecommunication device101 may also transmit, receive, or exchange data withother network devices220 via acommunication network213. Anetwork device220 may be adifferent communication device101 as illustrated inFIG. 1, or any other device accessible via acommunication network213.Network devices220 may include one ormore servers226, which may be used to store certain types of data, and particularly large volumes of data, for example, video data stored in one ormore data repository222. However, aserver226 may include any kind ofdata224 including programs, files, libraries, configuration data, index or tagging data, historical access or usage data, statistical data, security data, etc. Aserver226 may store and operate various applications relating to receiving, transmitting, processing, and storing the large volumes of data. It should be appreciated that various configurations of one ormore servers226 may be used to support and maintain thecommunication system100. Also, certain data may be stored in acommunication device101 which is also stored on theserver226, either temporarily or permanently, for example inmemory208 orstorage device218. The network connection may be any type of network connection, such as a cellular or wireless connection, an Ethernet connection, digital subscriber line, telephone line, coaxial cable, etc. Access to acommunication device101 can be controlled by appropriate security software or security measures. An individual users'110 access can be defined by thecommunication device101 and limited to certain data and/or actions. Accordingly, users110 and/or administrators of thecommunication system100 may be required to register with one ormore communication device101. For example, registered users110 or administrators may be able to manipulate data, such as by storing, editing, tagging, uploading, transmitting data or video content, rating content, suggesting content to other users110, etc.
• As noted previously, various options for managing data located within acommunication device101 and/or in aserver226 may be implemented. A management system may manage security of data and accomplish various tasks such as facilitating a data backup process. A management system may be implemented incommunication device101 and/or in anexternal server226. Accordingly, the management system may update, store, and back up data locally and/or remotely using any suitable method of data transmission, such as the Internet or anyother communication network213.
• FIG. 3 is a flowchart of anexample process300 for providing sonic signaling communication. Although theprocess300 is described with reference to the flowchart illustrated inFIG. 3, it will be appreciated that many other methods of performing the acts associated with theprocess300 may be used. For example, intervening processes or sub-processes may occur, the order of some of the blocks may be changed, and some of the blocks described are optional.
• Theexample process300 may begin with receiving, at a broadcast device, data representative of a sonic signal including an audible signal component having primary information and an inaudible signal component having secondary information (block302). For example, a television receives a radio frequency (“RF”) signal including video and audio components, the audio component including the audible portion of the television programming and an inaudible portion with additional information for reception by a user device. Typically, abroadcast device104 may automatically demodulate and/or decode data which was previously modulated and/or encoded by a broadcaster of content or content distributor to broadcast the content to users110. It should be appreciated that a television, or anyother broadcast device104, may receive signals to broadcast content using any one of a variety of standard formats or protocols including signals received via cables from a computer readable medium instead of via RF communication. The primary information may include any audible content which may be presented to the user, while the secondary information may include any additional content which may be received by theuser device106. For example, secondary information could include a text string, a URL, a shortened URL, or any other type of message only subject to the amount of data being delivered in the secondary information, which may be bound by technical considerations. It should be appreciated that a message may be broken down into subparts to be communicated as secondary information over time.
• Once the data representative of the sonic signal has been received, theexample process300 may continue with generating, at a broadcast device, a sonic signal including an audible signal component including primary information and an inaudible signal component including secondary information (block304). For example, a television may demodulate the received RF signal to generate a sonic signal including an audible portion below 18 kHz and an inaudible portion in the range of 18 kHz to 22 kHz. It should be appreciated that an inaudible portion as used herein refers to a sonic signal that is generally inaudible to typical human being over the age of eight years old. A signal may be inaudible because it is of a frequency which is not within the typical hearing range, or because the amplitude of the signal is too low, or a combination of these factors. To the extent that a human would be able to hear the machine signal which carries the secondary information, it is preferable for many applications that the noise heard would be minimally noticeable so as to not destroy the user's110 ability to receive the primary information provided in the sonic signal. In an example embodiment, a user110 may be able to hear a machine signal which includes secondary information and is generally audible. However, there are a variety of techniques which may be employed to provide the secondary information inaudibly, as discussed in further detail below. Also, it should be appreciated that demodulation of RF signals or other inputs to a television may follow various standards and protocols. Typically, an audio signal is generated or converted into in a standard format which is useable by a television. An audio signal may be stored in any format including, for example, MP2, MP3, AC-3, AAC, or HE-AAC.
• Theexample process300 may continue with transmitting, from a broadcast device, a sonic signal including an audible signal component and an inaudible signal component (block306). For example, a single television speaker produces the audible portion and the inaudible portion of the sonic signal. It should be appreciated that a sonic signal is typically transmitted by actuating a speaker to propagate the sonic signal through the air to a receiver (e.g., human ear, microphone). A single television speaker may be a commodity speaker, or stock speaker, which is included in the television. Alternatively, more than one speaker may be used, for example, current televisions are typically used with multiple speakers and may provide a stereo or other multi-speaker surround sound arrangement. For example, a television may transmit the received visual and audio signals of a programming signal from a network broadcast company in the standard manner, for example, by demodulating and/or decoding data which has been modulated and/or encoded in an RF signal for display on a screen and transmission through a speaker.
• Next, theexample process300 may continue with receiving the primary information in the audible portion of the sonic signal (block308). For example, a user110 hears the audible portion of an advertisement. The primary information may be any information which would normally be presented in audible form to a user110 listening to thebroadcast device104.
• In response to the transmission of the sonic signal, theexample process300 may continue with, receiving the inaudible portion of the sonic signal at a user device (block310). For example, a microphone of a mobile phone detects the inaudible portion of the sonic signal, for example, during an advertisement. The inaudible portion of the sonic signal may then be stored and deciphered in the mobile phone. In an example embodiment, the inaudible sonic signal may be provided during normal program content as opposed to a commercial break, for example, in relation to a product placement.
• The mobile phone may have an application which periodically polls the microphone to check for the presence of sound waves, for example, in the 18 to 22.05 kHz range. If found, the software may demodulate and/or decode the inaudible portion of the sonic signal in reverse to the prior modulation and/or encoding of the secondary information as the inaudible sonic signal. For example, the secondary information may be modulated using spread spectrum techniques, such as frequency-hopping spread spectrum (FHSS) or direct-sequence spread spectrum (DSSS). Using spread spectrum techniques may allow for weaker signals to be received by using a wider bandwidth. In an alternative example embodiment using spread spectrum techniques, one or more frequencies below 18 kHz may be used in the inaudible signal component of the sonic signal. It should be appreciated that, even though these frequencies are audible to most humans, the use of spread spectrum techniques may mask the machine signal. For example, using spread spectrum techniques may allow for use of lower power levels than would be perceivable by a human who is simultaneously listening to an audible signal.
• Next,example process300 may proceed with theuser device106 taking an action based on the secondary information of the inaudible portion of the sonic signal (block312). For example, the mobile phone determines the secondary information is a URL and uses the URL to access a web site that relates to the advertisement the user is listening to via a cellular network. Theuser device106 may be programmed to take a wide variety of actions, including displaying a visual or audible message to the user110 immediately or at a later time, opening or accessing an application, storing data in local or remote memory, etc. Theuser device106 may take an action without communicating with any other device, for example, theuser device106 may simply display a text message to the user110. In an example embodiment, theuser device106 does not display anything to the user110, but may update a user account, such as a rewards points account. For example, if a user watches a television program, awards points or rewards points may be awarded during the television programming. In an example embodiment, the points may only be awarded if the user device receives the secondary information from the sonic signal which is provided during commercial advertisements. Also, it may be preferable to broadcasters of content that viewers or listeners receive the programming in real-time. In an example embodiment, the secondary information may need to be received by theuser device106 in real-time in order to provide any benefit to the user110.
• It should be appreciated that theexample process300 may be ongoing continuously or intermittently. For example, sonic signal components including secondary information may be sent occasionally during the course of a television program. In an example embodiment, each commercial advertisement may have secondary information which is transmitted during the advertisement. It should be appreciated that the duration of the transmission of the secondary information may be based on the amount of data sent and other factors. For example, a message may be sent many times within a short period of time to ensure theuser device106 can reliably receive the message.
• A high level block diagram of an example communication system400 is illustrated inFIG. 4. The illustrated example communication system400 includes a plurality ofcommunication devices101, including a networkcontent server system402, atelevision set406, amobile phone410, and a usercontent web server414.
• The networkcontent server system402 could be a television broadcast station server storing television programming including commercial advertisements, promotional material, and the like. The networkcontent server system402 may include servers storing content and programming data, equipment for modulating and transmitting a broadcast signal with video and audio signal components, for example, including an encoder and a broadcast antenna. It should be appreciated that video and audio data can be transmitted using standard RF communication formats and protocols which are known in the industry.
• The networkcontent server system402 may add the audible portion of a program to a data signal which includes secondary information. For example, the secondary information is a message for a user110, which may include a character string which is digitally encoded as a series of bits, which is modulated as an inaudible signal. Encoding and/or modulating of secondary information may be performed using a black box service. A URL which may be encoded and modulated according to a predefined protocol and added to an audible signal with primary information, to form a sonic signal which when reproduced by abroadcast device104, such astelevision set406, will transmit an audible portion including primary information and an inaudible portion including secondary information. A black box service might begin its processing by shortening a URL using a service such as Bit.ly™. The resulting shortened URL may be converted into a binary format which may be modulated according to any of a variety of techniques to generate an audio file. A spread spectrum modulation technique may be preferred for certain applications, because increased security may be attainable with reception of relatively weaker signals. Accordingly, the audio file may include one or more ultrasonic frequencies and may be stored in a variety of formats. A black box service may be provided, for example, entirely by a third party, performed on a third party server, or may be performed entirely within the networkcontent server system402. Once the networkcontent server system402 has generated a signal to transmit, the signal may be transmitted as anRF signal404.
• Thetelevision set406 may receive and process RF signal404 using standard techniques and processes. For example, theRF signal404 may be demodulated to provide video and audio components. It should be appreciated that an RF signal may be transmitted via a variety of mediums (e.g., air, fiber optic cable, coaxial cable). It should also be appreciated that a television signal may be a digital data signal that is not an RF signal (e.g. TCP/IP data packets, FiOS). Thetelevision set406 may display the video signal on a screen and produce asonic signal408 using a speaker. Thesonic signal408 may include an audible portion which may be heard by a user110, and an inaudible portion which may be received by amobile phone410. Thetelevision set406 may supplement or modify the inaudible sonic signal component received by the networkcontent server system402. For example, if the inaudible sonic signal includes secondary information which is customizable, thetelevision set406, or anyother broadcast device104, may insert or embed additional data into the inaudible sonic signal prior to transmission to themobile phone410, or anyother user device106. If an inaudible sonic signal includes a variable which allows for custom information to be inserted, and no custom information is available, a stock message may be provided in the inaudible sonic signal. Also, thetelevision set406 may insert an inaudible signal component if no inaudible sonic signal component is received from the networkcontent server system402. For example, an advertisement for the television brand or manufacturer may occasionally be transmitted via an inaudible sonic signal.
• Themobile phone410 may be, for example, the user's110 cellular phone or laptop computer. As discussed above, amobile phone410 may check for an inaudible sonic signal using an application, for example, by periodically polling the microphone. It should be appreciated that similar software may run on anymobile phone410 that has an operating system that allows access to a microphone (e.g., iOS, Android, Blackberry OS, webOS, Windows Phone 7, Symbian). Software running on themobile phone410 may be a native application or a third-party application developed using libraries developed for use with themobile phone410. In the latter case, a “white label” application may be created or a software development kit may be distributed for implementing the system.
• Once an inaudible sonic signal is detected, software on themobile phone410 may attempt to demodulate the inaudible sonic signal using the reverse process of the modulating technique used. If an inaudible sonic signal is successfully demodulated, the resulting signal may represent the binary form of the input information, for example, a shortened URL. If only a unique key portion of a URL has been transmitted, a full URL may be recreated, for example, by prepending a protocol and domain name to the unique key. In order to allow for message customization, the software on themobile phone410 may optionally append unique identifiers to a recreated URL. In an example embodiment, a user ID, a geolocation coordinate, and/or a device ID may be appended to the URL in the form of URL parameters. The full URL may then be sent to a usercontent web server414, for example, as a mobile data connection or a WiFi connection illustrated asRF signal412. Optionally, a request, for example, a URL or shortened URL, may be transmitted using a secure protocol such as HTTPS. Further, in an example embodiment, themobile phone410 may not send any requests to external devices or servers, and may provide a user110 with user content from memory or the data received in an inaudible sonic signal.
• The usercontent web server414 receive a request from amobile phone410, or anyuser device106. For example, the usercontent web server414 may receive a shortened URL, expand the URL, and then return the response to themobile phone410. For example, if a request was made for a website, themobile phone410 may launch a browser to display the website page. In an example embodiment, the resource identified by a URL may be a web service, and the data returned to amobile phone410 may be processed before being displayed to the user110. In an example embodiment, third party applications may be launched by themobile phone410. A usercontent web server414 may perform a wide variety of tasks based on the receivedRF signal412, and accordingly, may be usefully implemented to provide substantial benefits to users110. For example, the usercontent web server414 may provide customized content, for example, rewards points may be credited to a user account and a customized message may be returned to themobile phone410.
• It should be appreciated that if the mobile phone's410 reception of thesonic signal408 is impeded by obstructions between thetelevision set406 and themobile phone410, thesonic signal408 may not be reliably received. For example, themobile phone410 may have trouble receiving the inaudible component of thesonic signal408 if themobile phone410 is in the user's110 pocket. It should be appreciated that the robustness of the system may be modified or adjusted based on the application at hand.
• A high level block diagram of an example communication system500 is illustrated inFIG. 5. The illustrated example communication system500 includes a plurality ofcommunication devices101, including a DVDproduction content system502, astereo system506, alaptop computer510, and a usercontent web server514. Thesecommunication devices101 are similar to the exemplary networkcontent server system402,television set406,mobile phone410, and usercontent web server414, which were described above in relation toFIG. 4.
• The DVDproduction content system502 may produce aDVD504 including content such as movies, music, video games, software, etc. An audio file stored on aDVD504 may have an inaudible signal with secondary information added to the primary audio information. For example, a movie stored on aDVD504 may include an advertisement or message relating to a new sequel. For example, amusic DVD504 may include artist and track information which may be transmitted with the music. Also, aDVD504 may include software which may be run locally at a broadcast device, for adding an inaudible signal to an audible signal as described above. It should be appreciated that the DVDproduction content system502 may produce computer readable media, other thanDVDs504, for performing the disclosed sonic signaling methods.
• Thestereo system506 may receive audio signals from aDVD504 to provide sound for a movie or to play music, or the like. Similar to thetelevision set406 described above, thestereo system506 may process an audio signal to produce asonic signal508, which includes an audible sonic signal component and an inaudible sonic signal component. It should be appreciated that thestereo system506 may additionally or alternatively receive an audio signal from any other data source (e.g., FiOS). Thestereo system506 may supplement or modify the inaudible sonic signal component to customize a message for a user110.
• Thelaptop computer510 may receive the inaudible sonic signal component of thesonic signal508. For example, thelaptop computer510 provides the user110 with information, such as the artist and track title of a currently playing song. Similar to themobile phone410, thelaptop computer510 may send a request to a usercontent web server514. The usercontent web server514 may receive, via anRF signal512, a request or message from thelaptop computer510. In response, the usercontent web server514 may send a message, web page, data file, or request to open an application to thelaptop computer510, for presentation to a user110. Similarly, thelaptop computer510 may send a response signal to astereo506, or anotherbroadcast device104. For example, the response signal may include a confirmation that an inaudible sonic signal was received by thelaptop computer510.
• In addition to a DVDproduction content system502, or a networkcontent server system402, many content producers may employ the disclosed sonic signaling communication system. For example, closed circuit content providers may provide content in a similar manner as discussed above. For example, in a grocery store or at a bus stop, a dedicated speaker may be providing music or spoken information to users110. These types of content providing systems may provide machine signals touser devices106, including inaudible signals, by supplementing audible signals that are already being transmitted during the normal course of business. Virtually any type of business or service may utilize the disclosed sonic signaling for communication and/or advertising purposes.
• FIG. 6 provides an example user interface600 displaying example user content602 via auser device106. In this example, the example user interface600 is illustrated as text message which displays an advertisement which may include a special offer for the user110. For example, a user110 may be walking through a store when an inaudible sonic signal is transmitted from an overhead speaker which is also playing music. The inaudible sonic signal may provide the illustrated message to the user110. For example, the user content602 may be time limited and may be customized to the user based on a user profile.
• In an example embodiment, an inaudible sonic signal includes a shortened URL, which is used to access a web page which may provide for an increased level of detail, such as images, animations, videos, audio, etc. For example, a coupon including a bar code may appear on a user's110 smartphone, which may then be scanned at the register of a grocery store. In an example embodiment, the user interface600 may display a wide range of messages to the user including, for example, emergency notification information, news bulletins, invitations to events, interesting trivia, donation requests, etc. Typically, a web browser may be used to display a web page on the user interface600. It should be appreciated that a user interface600 may be implemented using a visual display of information, audio communication, or any other output stimuli, as well as allowing a user110 to provide input for an improved user experience. For example, a web page may include an interactive game or allow a user to instantly purchase items, win prizes, interact with a social network, or the like. Also, for example, a printer may print a coupon, directions to a specified location, or some other message for the user110. It should be appreciated that coupon distribution may be performed selectively by targeting specific users110 using various filters or algorithms to determine a coupon distribution.
• It should be appreciated that broadcasters of content, including advertisers, may take advantage of the sonic signaling communication system disclosed herein in a wide variety of ways to increase the effectiveness of marketing, customer awareness and loyalty, and the like. Also, users110 may set controls as to the type of user content602 delivered via auser device106, for example, with settings on theuser device106 or at a web site for controlling content by opting in or opting out of receiving certain user content602. Further, allowing access to third parties may require user110 consent. For example, an inaudible sonic signal which requests that a user access a URL may require user approval, and should the user110 not approve the access of the user content602 at the URL, a text message or other message which may be a subset of the full message may be provided on theuser device106. Additionally, a message for a user may invoke a social media (e.g., Twitter), which may introduce a viral coefficient into the system.
• It will be appreciated that all of the disclosed methods and procedures described herein can be implemented using one or more computer programs or components. These components may be provided as a series of computer instructions on any conventional computer-readable medium, including RAM, ROM, flash memory, magnetic or optical disks, optical memory, or other storage media. The instructions may be configured to be executed by a processor, which when executing the series of computer instructions performs or facilitates the performance of all or part of the disclosed methods and procedures.
• It should be understood that various changes and modifications to the example embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
