1. Field of the Invention
This invention relates generally to earcons, and more particularly to a method for providing intelligent consumer earcons to mobile and fixed landline communication subscribers.
2. Description of the Related Art
Earcons are auditory icons. Earcons are sounds or tones used to represent a specific event, item, or object. An earcon can be parameterized by specific attributes of the item or event. Earcons also employ sound cues about the content and organization of information. Earcons are generally not auditory caricatures of the signified item or event, that is, they are abstract rhythmic/melodic patterns rather than everyday sounds.
The utilization of earcons or non-speech audio with various user-interfaces is becoming increasingly popular due to the potential benefits earcons offer. An earcon is a useful complement to visual output, because earcons can increase the amount of information communicated to the user, or reduce the amount of information the user has to receive through the visual channel. Earcons make use of the auditory senses, which is powerful but under-utilized sense in most current interfaces.
Earcons are commonly utilized in automobiles, consumer electronics, computers, and communication applications. For example, the sounds a driver hears when leaving the car lights on or the key in the ignition are earcons. Further examples of earcon usage are user audio prompts, such as when a person is prompted to leave a message after the “beep”, interactive and automated phone services, or to withdraw their cash at an automated transaction machine with auditory cues.
Embodiments of the present invention include a method for utilizing earcons, the method includes: forming a database of earcons; forming a user profile and preferences database; monitoring user audio content; monitoring the user environment; playing a series of earcons from the database of earcons on a user's communication device; wherein the series of earcons are chosen from the database of earcons based on the user profile and preferences database; and wherein the playing of individual earcons from the series of earcons is based on the monitored user audio content and environment.
In one aspect of the invention, the database of earcons is comprised of at least one of the following: company, product, service, retail location, and earcon length information, the user profile and preferences database is comprised of user and observationally supplied user profile information, and the user profile and preferences database is comprised of user biometric data, wherein the user biometric data comprises gender of the user; age of the user; accent of the user; native language of the user; dialect of the user; socioeconomic classification of the user; educational level of the user; and emotional state of the user. In addition, the user profile and preferences database is comprised of user preferences, wherein the user preferences comprise the types of companies, products, services the user wants to receive earcons about; and wherein the user preferences further comprise specified audio levels, lengths, and points in the usage of the communication device and the conversation for playing the earcons.
In another aspect of the invention, the monitoring of user audio content comprises using a speech recognition system to detect and interpret conversational content; wherein based on the interpreted conversational content earcons are chosen for playback on the user's communications device. In addition, the monitoring of user audio content is used to determine pauses in the user's conversation, and wherein based on the determined pauses and their respective length, earcons are chosen for playback on the user's communications device.
In another aspect of the invention, the monitoring of the user environment comprises tracking the location of the user, wherein the tracking of user location comprises the use of at least one of the following: global positioning system (GPS) satellites and related electronic device chip sets within the communication devices, cellular phone infrastructure, and Internet gateways. Wherein based on the user location an earcon is chosen for playback on the user's communications device.
In another aspect of the invention, the communication devices comprise cellular phones, fixed landline phone, mobile computing devices, and desktop computers, wherein the cellular phones, the mobile computing devices, and the desktop computers are configured with voice over Internet protocol (VOIP).
As a result of the summarized invention, a solution is technically achieved for a method and system for utilizing intelligent consumer earcons (ICE) that detect the audio surroundings of a user on a communications device, and based on detected audio information plays earcons of companies and businesses.
The subject matter that is regarded as the invention is particularly pointed out and distinctly claimed in the claims at the conclusion of the specification. The foregoing and other objects, features, and advantages of the invention are apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
The detailed description explains the preferred embodiments of the invention, together with advantages and features, by way of example with reference to the drawings.
Embodiments of the invention provide a method and system for utilizing intelligent consumer earcons (ICE) that detect the audio surroundings of a user on a communications device, and based on detected audio information play earcons related to companies and businesses. In an exemplary application of an embodiment of the invention, when a user is discussing a company, product, or service offered by the company on their communications device, a speech recognition system detects and interprets the conversational content, and plays a sound that will remind the user of the company. However, it is important to note that the sound played does not interfere in the user's conversation and acts as a quiet advertising reminder. In embodiments of the invention, control of the introduction of earcons to the user's conversation may be accomplished by creating a user profile (e.g., age, sex, income and preferences for volume levels and which companies the user wishes to receive advertisements from. In embodiments of the invention, earcons may also be created to inform the user of information related to both their discussion and the company from which they are receiving advertisement. For example, if a user is on their communication device discussing a new consumer device, the ICE system may play a company earcon informing the user of a newer consumer device just released, by playing an earcon the user can identify as “new product available.”
In embodiments of the invention ICE systems are also utilized to assist a consumer in locating a store or company location by using the global positioning satellite (GPS) system. For example, if a user is on a communication device discussing a brand of coffee, the coffee brand earcon will play, and then an earcon indicating that the brands coffee shop is nearby will follow. Embodiments of the invention have earcons that may be adjusted to the user's preferences. The user can be informed with a simple “beep” when a store is near, or various different sounds, with different rhythms that may indicate direction and proximity. The user's location is tracked using GPS and then correlated with the nearest company or store the user is discussing.
In another embodiment of the invention, the ICE system may be utilized to search for another person. People often identify their location by using local stores or companies as landmarks. The ICE system can help people find each other and also provide valuable advertising opportunities. For example, if a person is looking for a friend who says they are near a certain store in a busy urban intersection. The ICE system recognizes the name of the store and plays the store's earcon, and then a subsequent earcon that indicates the proximity of the nearest store.
User profiles and databases (blocks 104, 108) for requesting and controlling earcon content may be resident on the individual communication devices (102, 104, 124, 126) or stored within the server 122 or cellular base station 112. The software for running the intelligent earcon system (block 120), and a database of available earcons (block 118) may be resident on the server 122 or cellular base station 112.
Location information for implementing positional aspects of the intelligent earcon system may be obtained via global positioning system (GPS) satellites 116 and related electronic device chip sets within the mobile communication devices (102, 104), or via terrestrial infrastructure such as the cellular phone system (112, 114), or Internet gateways. Methods such as triangulating an RF transmission between cell sites (112,114) have proven effective in locating a transmitting device. In a wireless local area network (WLAN), the Internet gateway and the associated Internet protocol (IP) address may be used to locate the mobile communication devices (102, 104).
An example of utilizing the exemplary system 100 for implementing an intelligent earcon system is as follows. A first subscribing user places a call with their mobile communication device 102 to a second subscribing user with mobile communications device 106. Both of the subscribing users have their own user profile and database (blocks 104, 108), which contain information on the user's preferences for earcons and basic information on the user. The first subscribing user (represented by mobile communications device 102) may only wish to receive earcons from a specified service provider, and wishes to be informed of new products and store locations regularly. The second subscribing user (represented by mobile communications device 106) may only wish to receive earcons from a specified coffee provider and wishes to be informed of store locations and exact directions by earcon when prompted through speech recognition. The ICE system 120 is linked to both users (102, 106), and actively monitors their conversation in order to include appropriate earcons from the earcon database 118, based on the individual user profiles (104, 108). The users (102, 106) are tracked using GPS 116 to facilitate the ICE system 120 in informing the user of store locations with the appropriate earcon.
The database of earcons (block 202) contains information about the various earcons within the earcon system, and tracks which earcon corresponds to which company and their products and services. The service agreement database (block 208) contains information about which company allows the use of their earcons. The service agreement database (block 208) also contains information about privacy and legal conditions. The identification of earcons (block 212) identifies pertinent earcons based on audio/video (A/V) data and positional data (block 200) and service agreement (block 208) from the database of earcons (block 202). The appropriate context for presenting the earcon is determined by the identifier of context (block 216) based on the interpretation of the data (block 214). The identification of the earcon communication channel (block 218) is based on the determined context (block 216). For example, earcons may be communicated via ring-tones. The identifier of the communication channel (block 218) determines when earcons may be communicated (during natural pauses and silence, or as background music). The identification of current earcon (block 220) identifies earcons that fit a given situation by duration, context and by the user profile. Finally, the earcon is played (block 222) for the user.
The semantic analyzer (block 300) defines a general category where the given semantic content occurs. For example, if the semantic content is relating to a question/answer such as: “I love to drink cola?” “We need to stop and buy it”—the situation category can be expressed as “DRINKING.” Similarly any phrases about love, meetings with girlfriends, etc. may be expressed as the situation “SEX.” Phrases about children, wife, husband, mother or father may be expressed as the situation “FAMILY” or the content may be more in-depth, such as FAMILY-MEETING-YEAR-1996 in a given year (e.g., was 1996 a very significant year from the perspective of family life). The semantic representation of the phrase is used to define conversational pauses. For example, semantic representations may define that the topic of the conversation is switched. If there is also a prolonged silence then this means that this silence coincides with the end of one topic of conversation and a new topic is not yet started. The semantic analyzer (block 300) is capable of recognizing such phrases as “Please, wait, I will find a telephone number”. This creates a natural conversation pause.
In addition, the identification of conversational pauses/silence (block 302) may also be accomplished with a tonal and inflection analyzer that analyzes speech to detect ends of sentences (punctuation), and assists in the identification of conversational pauses.
A semantic analyzer of the environment (block 304) employs a situation recognition module that uses known recognition technologies in all possible media such as speech recognition, image recognition and pattern recognition. The situation recognition module produces strings of units (labels) that have semantic meaning (like words from speech). A statistical parser that permits the attachment of syntactic structures to these strings processes these strings of units. Then, in the process of interpretation, strings of units get semantic meanings that “explain” situations and environment. Examples of environments that the system may recognize are:
A person speaks in a car
It is very hot summer
This is a conference call where several people participate
a caller is walking on a noisy street, etc.
Examples of a semantic analyzer of environment (block 304) with a situation recognition module are provided in U.S. Pat. No. 6,792,339 entitled “Artificial Passenger with Condition Sensors,” and is also described in patent application publication U.S. 20050192730 entitled “Driver Safety Manager” which are both hereby incorporated by reference herein in their entirety. The in-vehicle applications of the semantic analyzer may be readily extended to other environments.
An identification of environmental impact module (block 306) identifies the impact of environment on a user and their conversation. The identification of environmental impact is done by a set of rules that associate with each situation and environment a set of possible consequences of this environment on the user and their conversation. For example, if a person is driving, there can be natural pauses because the driver pays attention to their driving and not because of their conversation, and therefore the driver should not be distracted with earcons. The preceding example defines a rule to check for driver attention if there is a conversational pause. Driver attention may be defined as found in U.S. Pat. No. 6,792,339 and patent publication U.S. 20050192730A1. If a user is on a noisy street then the rule may either require the suspension of earcon usage, or require the selection of earcons that may be comprehended in noisy environments.
The interpretation of user biometrics (block 308) is based on the detection and definition of user biometrics. Examples of user biometrics include: gender of the user; age of the user; accent of the user; native language of the user; dialect of the user; socioeconomic classification of the user; educational level of the user; and emotional state of the user. The user biometrics may be used to choose an appropriate earcon. For example, the educational level of the user may determine the types of earcons that are targeted for them. The dialect of a user may be used to present earcons oriented to places where user came from. Detection and definition of user biometrics is disclosed in U.S. Pat. No. 6,665,644 entitled “Conversational Data Mining,” and is incorporated by reference herein in its entirety.
The identification of user attention (block 310) is based on the user biometrics as described in U.S. Pat. No. 6,792,339 and patent publication U.S. 20050192730A1.
The identification of a channel and appropriate time period to insert and play an earcon (block 312) is determined from the inputs obtained from the identification of conversational pauses/silence (block 302), the identification of environmental impact module (block 306), and the identification of user attention (block 310), as well as a set of rules. For example, if a long pause is expected while a teenage user speaks over a mobile communication device, and the teenage user is located near a bookstore, and the teenage user is an avid reader of a specific series of books, and there is a new book in that series, an earcon for the new book may be played. The rules can be provided in a form of statistical machine, and have a set of rules for prediction of user behavior and reaction as described in U.S. Pat. No. 4,870,579 entitled “System and Method of Predicting Subjective Reactions”, incorporated by reference herein in its entirety. An advanced technique for prediction of situations is described in U.S. patent application publication 20060190822A1 entitled “Predictive User Modeling in User Interface Design”, incorporated by reference herein in its entirety.
The synchronization block 412 gathers the data from the data sources (blocks 402, 404, 406, 408, 410), and synchronizes the data using time stamps. A relevance determination module (block 414) determines the relevancy of the synchronized data. For example, the relevance determination module (block 414) establishes that video of a car that passes a user and a street noise are related—the noise comes from this car. The synchronization is required for the semantic processing that was described in
Block 502 provides information about earcon time duration. Specifically, short duration earcons that may be played during a few seconds, and long duration earcons that may be played for longer periods of time up to several minutes. Block 504 identifies the relevancy of earcons from the set of earcons (block 500) to a current user situation. Examples of determinations of relevancy include: how relevant the earcons are to the available channel and time period, how relevant the earcons are to the topic that the user is discussing, relevancy of earcons to the environment where the user is located, the expected length of pauses in a conversation, user attitude, etc. Block 506 checks for privacy relevance, and verifies that an earcon that is played does not intrude user privacy. For example, if the earcon has the potential to be overheard by other users, the earcon is checked so that it does not disclose user intent or user interests. Examples of techniques for managing privacy information are given in U.S. Pat. No. 7,234,065 entitled “System and Method for Managing Data Privacy”, incorporated by reference herein in its entirety. Block 508 is an ultimate selector of earcons based on information provided by blocks 502, 504, and 506. The ultimate selector (block 508) chooses the earcon that best matches all restrictions that were identified in blocks 502, 504, and 506. The ultimate selector (block 508) uses scores of importance to rank each factor provided by blocks 502, 504, and 506, and chooses the available earcon with highest score.
