At least one of video, audio, and image analytics of electronically sensed data is performed to determine a presence of the second user at a third system. When the second user is determined to be present at the third system, the second user is provided with a first indication indicative of the first signal, the first indication being provided via a pervasive communication application in execution on the third system and other than the first communication application.

## Background
This application claims the benefit of U.S. Provisional Patent Application No. 61/370,509, filed on Aug. 4, 2010, the entire contents of which are incorporated herein by reference.


FIELD OF THE INVENTION
The instant invention relates generally to telecommunication methods and systems, and more particularly to a method and system for completing a communication request by a first user based on a sensed presence of a second user at a remote location.
BACKGROUND OF THE INVENTION
Telecommunication technologies allow two or more parties to communicate almost instantly, even over vast distances. In the early part of the last century, landline telephones became essentially ubiquitous in developed countries. More recently, cellular wireless telephone networks have emerged, allowing two or more parties to communicate with one another from virtually anywhere within a cellular network coverage area.
Videoconferencing has also emerged recently as a viable alternative to voice-only communication. A videoconference is a set of interactive telecommunication technologies, which allow two or more parties to interact via two-way video and audio transmissions simultaneously. Webcams are popular, relatively low cost devices that can provide live video streams via personal computers, and that can be used with a suitable software client for videoconferencing over the Internet.
Voice over Internet Protocol (VoIP) software clients, such as for instance Skype®, support voice-only and/or videoconferencing communication between two or more parties. During use, the VoIP application is in execution on a computer or on another suitable device that is associated with a first party. The VoIP application, and other similar applications, typically provides a list of user names associated with other parties, including an indication of the current status of each of the other parties. Accordingly, a first user can determine when another user is online for a Skype to Skype (VoIP) chat or call, unless the other user wishes to remain hidden. When a second party appears to be available, the first party may attempt to initiate a communication session with the second party. For instance, the first party selects from the list a user name associated with the second party, and then selects an option for initiating a “call” to the second user. The VoIP application that is in execution on a computer or on another suitable device associated with the second party causes an alert to be issued, such as for instance playing a “ringing” sound via a speaker of the computer or other suitable device. In response to the alert, the second party answers the “call” originating from the first party.
Unfortunately, it is not possible to initiate a communication session when the VoIP application is not in execution on the computer or other suitable device that is associated with the second party. In a prior art system, when the VoIP application is not in execution, the first party merely receives a message indicating that the second party is not available, and is invited to leave a voice message for the second party. Of course, the second party does not receive the voice message until the next time the VoIP application is launched. Often, by the time the second party receives the voice message the first party is no longer interested in establishing a communication session.
It would be advantageous to provide a method and system for making video calls that overcomes at least some of the above-mentioned limitations of the prior art.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
The following description is presented to enable a person skilled in the art to make and use the invention, and is provided in the context of a particular application and its requirements. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the scope of the invention. Thus, the present invention is not intended to be limited to the embodiments disclosed, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
FIG. 1 is a simplified block diagram of a system according to an embodiment of the instant invention. A first user system 100 is provided in communication with a second user system 102, via a communication network 104. For instance, the communication network 104 is an Internet Protocol (IP) network. The first user system 100 is associated with a first user and the second user system 102 is associated with a second user. At least the second user system 102 comprises an electronic sensor 106 for sensing data within a sensing area of the second user system 102. For instance, the electronic sensor 106 is one of an audio sensor for sensing audio data and an image sensor for sensing image or video data. Optionally, the first user system 100 also comprises an electronic sensor 108 for sensing data within a sensing area of the first user system 100. Some specific and non-limiting examples of suitable image sensors include one of a web cam and an IP camera, either of which may be provided in communication with the second user system 102 or the first user system 100 via a USB port or via a wireless communication interface. Optionally, the image (or video) sensor is designed to operate in one or more of the visible and infra-red regions of the electromagnetic spectrum. Optionally, in order to support bidirectional audio and video communication between the first user and the second user, the first user system 100 and the second user system 102 each comprise both an audio sensor and a video sensor, as well as audio and video output devices, such as for instance a display screen and speakers, respectively. By way of a specific and non-limiting example, the first user system 100 and the second user system 102 each comprise a microphone and a web cam or another type of video camera. Optionally, one or both of the microphone and the web cam are external peripheral devices of the first and second user systems. Optionally, one or both of the microphone and the web cam are integrated devices of the first and second user systems.
The first user system 100 further comprises a processor 110 and the second user system 102 further comprises a processor 112, the processors 110 and 112 being for executing machine readable code for implementing at least one of an email application, a social networking application (such as Facebook®), a Voice over Internet Protocol (VoIP) application such as for instance Skype®, an instant messaging (IM) application, or another communication application. Furthermore, the processor of at least one of the first user system 100 and the second user system 102 is for analyzing data that are sensed using the sensor 106 of the second user system 102. In particular, the analysis comprises at least one of audio, image (such as based on a still image, or such as based on a frame or a set of frames of video data) and video analytics of the sensed data. More particularly, the analysis comprises comparing the sensed data with template data relating to the second user. For video data, an image database and search tools are employed for performing the analysis. Still more particularly, the second user is identified uniquely based on determining a match between the template data and the sensed data. Optionally, the electronic sensor 106 of the second user system 102 is an edge device that is capable of performing the at least one of audio, image and video analytics of the data that are sensed thereby.
During use, the first party uses a first software application in execution on the first user system 100 to initiate a communication session between the first party and the second party, via the communication network 104. For instance, the first party uses the Skype® software application or another similar Voice over Internet Protocol (VoIP) software client to select the second party from a list of usernames. A first signal is transmitted from the first system 100 for delivery to, or for initiating a communication session with, the second party via a second software application, such as for instance the Skype® software application or another similar VoIP software client.
When the second software application is not in execution on the second user system 102, then at least one of audio, image and video data is sensed within a sensing area of the sensor 106 of the second user system 102. For instance, by way of a specific and non-limiting example, video data is sensed within a field of view (FOV) of the sensor 106. The sensed video data, in the instant example, is analyzed subsequently in order to determine a presence of the second user at the second user system. Optionally, audio and/or image analytics of sensed audio and/or image data, respectively, is performed either in place of or in addition to the video analytics of sensed video data.
In one implementation, at least one of video, image and audio analytics of the sensed data is performed using at least a process in execution on the processor 112 of the second user system 102, or on a processor of the sensor 106 when said sensor 106 is an edge device that is capable of performing on-board analytics processing. The processing that is performed locally to the second user system 102 optionally is for detecting at least one of i) motion (relatively simple analytics), ii) the presence of a person (medium relative difficulty analytics), or iii) unique identification of a specific person (highest relative degree of difficulty). Optionally, the processing that is performed locally to the second user system 102 tracks a time property of the sensed data, such as for instance whether i) a specific person is passing by the second user system 102, or ii) the specific person is seated at the second user system 102, etc. Further optionally, the sensed data are partially analyzed locally to the second user system 102, such as for instance to detect motion or to detect a person, and the sensed data are subsequently transmitted to another system, such as for instance the first user system 100 to undergo an analytics process of higher relative difficulty, such as for instance identifying uniquely the second user based on the sensed data. Optionally, the higher relative difficulty analytics comprises determining facial characteristics of the sensed person, and/or comparing the sensed data to a database of known faces, etc.
In a second implementation, the sensed data is transmitted initially via the communication network 104 to the first user system 100 and at least one of video, image and audio analytics of the sensed data is performed using a video analytics process in execution on the processor 110 of the first user system 100.
Optionally, transmitting video data between the second user system 102 and the first user system 100, via communication network 104, comprises streaming the video data, or alternatively it comprises “trickling” individual non-adjacent frames of video data as is described in United States Provisional Patent Application 61/249,384 entitled “Video Analytics Method and System,” the entire contents of which are incorporated herein by reference. Optionally, video analytics and/or audio analytics processing is distributed to a plurality of other first user systems, such as for instance user systems of a plurality of other Skype® users in a peer-to-peer approach
When a result of the video analytics is indicative of the second user being present at the second user system 102, a first indication is provided to the second user via a pervasive communication application that is in execution on the second user system 102. The pervasive communication application is other than the second communication application, which during use is not in execution on the second user system. Accordingly, in the instant example the second user receives an indication via a software application other than the Skype® software application, informing the second user that the first user has attempted to establish a communication session. Optionally, the first indication prompts the second user to launch the second software application on the second user system. Some non-limiting examples of the applications other than Skype® include social networking applications (such as Facebook®, e-mail, gmail, instant messaging (IM), gtalk, AIM, MSN Messenger, etc.).
A specific example is provided in order to facilitate a better understanding of the operation of the system of FIG. 1. According to the example, the first user launches the Skype® software application on the first user system 100 and selects the second user from a list of contacts. The first user initiates a call to the second user by clicking on the “call” button within the Skype® user interface. Although the second user is present at a location of the second user system 102, the Skype® software application is not in execution on the second user system 102. Since the “call” cannot be connected as requested by the first user, a Skype® server of the communication network 104 provides a message to the first user via the Skype® software that is in execution on the first user system 100. Upon receiving the message from the Skype® server, a video analytics process in execution on the first user system 100 begins receiving captured video data from the second user system 102 via communication network 104. The video analytics process retrieves stored template data for the second user from a not illustrated memory device of the first user system, or from a memory device located at a centralized location. Based on a comparison of the captured video data with the template data, the second user is identified uniquely and is determined to be present at the location of the second user system 102. The first user system 100 provides an indication via a pervasive communication application that is in execution on the second user system 102, such as for instance a social networking application (such as Facebook®), e-mail, gmail, instant messaging (IM), gtalk, AIM, MSN Messenger, etc., the indication being indicative of the attempt by the first user to establish the Skype® call with the second user. Upon receiving the indication, the second user launches the Skype® software application on the second user system 102, logs in, and completes the Skype® call with the first user.
Optionally, instead of identifying the second user uniquely, video/image/audio analytics is performed to detect “a” person within a sensing area of the electronic sensor 106, after which a prompt is provided via the pervasive communication application requesting the detected person to provide a unique identification (such as speak a user name, password, employee number, etc.) or provide a biometric sample such as a voice sample or high-quality facial image. Unique identification of the detected person as the second user, in this implementation, is based on a combination of the result of relatively less difficult analytics processing and user identification data that is provided by the detected person.
FIG. 2 is a simplified block diagram of a system according to an embodiment of the instant invention. A first user system 200 is provided in communication with a second user system 202, via a communication network 204. For instance, the communication network 204 is an Internet Protocol (IP) network. A third system 206 is also in communication with at least one of the first user system 200 and the second user system 202 via the communication network 204. The first user system 200 is associated with a first user and the second user system 202 is associated with a second user. The first user system 200 comprises a processor 208 and the second user system 202 comprises a processor 210, the processors 208 and 210 are for executing machine readable code for implementing at least one of an email application, a social networking application (such as Facebook®), a Voice over Internet Protocol (VoIP) application such as for instance Skype®, an instant messaging (IM) application, or another communication application.
An electronic sensor 212 is co-located with the second user system 202. In the instant example, the electronic sensor is, for instance, a network (IP) camera capable of streaming video data to the third system 206 via the communication network 204, or it is a cellphone camera that provides data over a cell phone or Wi-Fi network, etc. Optionally, the image (or video) sensor is designed to operate in one or more of the visible and infra-red regions of the electromagnetic spectrum. In this example, the electronic sensor 212 is not in communication with the second user system 202. For instance, the electronic sensor 212 is a security camera that is dedicated to providing video data to the third system 206, which is for instance a video analytics server or a server farm having in execution thereon at least one video analytics process for performing video analytics of video data that is received from the electronic sensor 212. In one particular implementation, the electronic sensor 212 captures video data continuously and the video data is streamed to the third system 206 in response to receiving a request from the third system 206. Optionally, the electronic sensor 212 senses one or more of audio, image and video data, and uses that as a “trigger” to initiate data transfer. Optionally, one or more of audio, image and video analytics of the sensed data is performed. In another implementation, the electronic sensor 212 is an edge device that is capable of performing the one or more of audio, image and video analytics of the data that are sensed thereby. According to at least one implementation, analysis of the sensed data comprises comparing the sensed data with template data relating to the second user. More particularly, the second user is identified uniquely based on determining a match between the template data and the sensed data.
Optionally, the first user system 200 and the second user system 202 also comprise not illustrated audio and video sensors for supporting bidirectional audio and video communication between the first user and the second user, as well as audio and video output devices, such as for instance a display screen and speakers, respectively. By way of a specific and non-limiting example, the first user system 200 and the second user system 202 each comprise a microphone and a web cam or another type of video camera. Optionally, one or both of the microphone and the web cam are external peripheral devices of the first and second user systems. Optionally, one or both of the microphone and the web cam are integrated devices of the first and second user systems.
During use, the first party uses a first software application in execution on the first user system 200 to initiate a communication session between the first party and the second party, via the communication network 204. For instance, the first party uses the Skype® software application or another similar Voice over Internet Protocol (VoIP) software client to select the second party from a list of usernames. A first signal is transmitted from the first system 200 for delivery to, or for initiating a communication session with, the second party via a second software application, such as for instance the Skype® software application or another similar VoIP software client.
When the second software application is not in execution on the second user system 202, then at least one of audio, image and video data is sensed within a sensing area of the sensor 212 that is co-located with the second user system 202. For instance, by way of a specific and non-limiting example, video data is sensed within a field of view (FOV) of the sensor 212. The sensed video data, in the instant example, is analyzed subsequently in order to determine a presence of the second user at the second user system. Optionally, audio and/or image analytics of sensed audio and/or image data, respectively, is performed either in place of or in addition to performing video analytics of sensed video data. In particular, the sensed data is transmitted from the sensor 212 to the third system 206 via the communication network 204. At least one of video, image and audio analytics of the sensed data is then performed using at least a process in execution on the third system 206. The processing that is performed using the at least a process in execution on the processor of the third system 206 optionally is for detecting at least one of i) motion (relatively simple analytics), ii) the presence of a person (medium relative difficulty analytics), or iii) unique identification of a specific person (highest relative degree of difficulty). Optionally, the processing that is performed using the at least a process in execution on the processor of the third system 206 tracks a time property of the sensed data, such as for instance whether i) a specific person is passing by the second user system 202, or ii) the specific person is seated at the second user system 202, etc. Further optionally, the sensed data are partially analyzed locally to the second user system 202, such as for instance to detect motion or to detect a person, and the sensed data are subsequently transmitted to the third system 206 to undergo an analytics process of higher relative difficulty, such as for instance identifying uniquely the second user based on the sensed data. Optionally, the higher relative difficulty analytics comprises determining facial characteristics of the sensed person, and/or comparing the sensed data to a database of known faces, etc.
Optionally, transmitting video data between the second user system 202 and the third system 206, via communication network 204, comprises streaming the video data, or alternatively it comprises “trickling” individual non-adjacent frames of video data as is described in United States Provisional Patent Application 61/249,384 entitled “Video Analytics Method and System.” Optionally, video analytics and/or audio analytics processing is distributed to a plurality of other first user systems, such as for instance user systems of a plurality of other Skype® users in a peer-to-peer approach.
When a result of the video analytics is indicative of the second user being present at the second user system, a first indication is provided to the second user via a pervasive communication application that is in execution on the second user system 202. The pervasive communication application is other than the second communication application, which during use is not in execution on the second user system 202. Accordingly, in the instant example the second user receives an indication via a software application other than the Skype® software application, informing the second user that the first user has attempted to establish a communication session. Optionally, the first indication prompts the second user to launch the second software application on the second user system 202. Some non-limiting examples of the applications other than Skype® include social networking applications (such as Facebook®, e-mail, gmail, instant messaging (IM), gtalk, AIM, MSN Messenger, etc.).
A specific example is provided in order to facilitate a better understanding of the operation of the system of FIG. 2. According to the example, the first user launches the Skype® software application on the first user system 200 and selects the second user from a list of contacts. The first user initiates a call to the second user by clicking on the “call” button within the Skype® user interface. Although the second user is present at a location of the second user system 202, the Skype® software application is not in execution on the second user system 202. Since the “call” cannot be connected as requested by the first user, a Skype® server of the communication network 204 provides a signal to the third system 206, the signal being indicative of a failure to complete the call. Upon receiving the signal from the Skype® server, a video analytics process in execution on the third system 206 begins receiving captured video data from the electronic sensor 212 that is co-located with the second user system 202 via communication network 204. The video analytics process retrieves stored template data for the second user from a not illustrated memory device of the third system 206. Based on a comparison of the captured video data with the template data, the second user is identified uniquely and is determined to be present at the location of the second user system 202. The third system 206 provides an indication via a pervasive communication application that is in execution on the second user system 202, such as for instance a social networking application (such as Facebook®, e-mail, gmail, instant messaging (IM), gtalk, AIM, MSN Messenger, etc., the indication being indicative of the attempt by the first user to establish the Skype® call with the second user. Upon receiving the indication, the second user launches the Skype® software application on the second user system 202, logs in, and completes the Skype® call with the first user.
Optionally, instead of identifying the second user uniquely, video/image/audio analytics is performed to detect “a” person within a sensing area of the electronic sensor 212, after which a prompt is provided via the pervasive communication application requesting the detected person to provide a unique identification (such as speak a user name, password, employee number, etc.) or provide a biometric sample such as a voice sample or high-quality facial image. Unique identification of the detected person as the second user, in this implementation, is based on a combination of the result of relatively less difficult analytics processing and user identification data that is provided by the detected person.
In the examples that are presented above, the first user attempts to initiate a communication session with the second user via a VoIP software application. Alternatively, the first user attempts to communicate with the second user via one of an email application, a social networking application, an instant messaging application or another communication application. When it is determined that the second user has not received the communication attempt, because a corresponding software application is not currently in execution on the second user system, then at least one of audio, image and video analytics of data that are sensed at a location of the second user system is performed to determine a presence of the second user at the second user system. When the second user is determined to be present, then an indication is provided to the second user via a pervasive communication application other than the corresponding software application. The indication informs the second user that the first user is attempting to communicate by one of email, a social networking application, instant messaging, VoIP, etc. Since the second user is identified uniquely based on sensed data, prior to the indication being provided, the indication is always provided to the intended recipient. In other words, the indication is not provided unless the second user is first identified at the second user system. In this way, users are not bothered by indications that are intended for other users.
Referring now to FIG. 3, shown is a simplified flow diagram of a method according to an embodiment of the instant invention. At 300, using a first system, a first signal is transmitted from a first user for delivery to a second user. In particular, the first signal is provided via a first communication application that is in execution on a first user system, for being delivered to the second user via a second communication application. At 302 it is determined whether or not the second communication application is in execution on a second user system that is associated with the second user. When it is determined at 302 that the second communication application is in execution on the second user system, then at 304 the first signal is provided to the second user via the second communication application. When it is determined at 302 that the second communication application is not in execution on the second user system, then at 306 at least one of audio, image and video data is sensed using an electronic sensor that is co-located with the second user system. For instance, a video camera is used to capture video data at a location of the second user system. At 308 it is determined whether or not the second party is identified within the sensed data. For instance, at least one of audio, image and video analytics of the sensed data is performed to identify the second user at the location of the second user system. When it is determined at 308 that the second party is not identified within the sensed data, then the method returns to 306 and additional data is sensed. When it is determined at 308 that the second party is identified within the captured image data, then at 310 an indication is provided to the second user via a pervasive communication application that is other than the second communication application. Optionally, the attempt to provide the indication to the second user is performed in a cascading manner. For instance, a first attempt is made to provide the indication via a social networking application (such as for instance Facebook®), followed by an attempt using Yahoo mail, followed by an attempt using America Online instant messaging, etc. As discussed above, identification of the second user may involve performing one or more of video, image and audio analytics. In addition, identification may be based on distributed analytics processes, such as for instance including analytics performed locally to the second user system, as well as analytics performed at the first user system or a third system (such as an analytics server, an analytics server farm or an analytics broker system). Further optionally, the at least one of video, image and audio analytics may be performed to merely detect motion or the presence of any person, followed by a prompt to the detected person to identify himself or herself
Referring now to FIG. 4, shown is a method of communicating between a first user and a second user according to an embodiment of the instant invention. At 400, using a first system, a first signal is transmitted from the first user for delivery to the second user via a first communication application. At 402 a processor of a second system is used to perform at least one of video, audio, and image analytics of electronically sensed data, to determine a presence of the second user at a third system. At 404, when the second user is determined to be present at the third system, a first indication indicative of the first signal is provided to the second user, the first indication being provided via a pervasive communication application that is in execution on the third system, wherein the pervasive communication application is other than the first communication application. Optionally, the attempt to provide the indication to the second user via the pervasive communication application is performed in a cascading manner. For instance, a first attempt is made to provide the indication via a social networking application (such as for instance Facebook®), followed by an attempt using Yahoo mail, followed by an attempt using America Online instant messaging, etc.
In the method of FIG. 4, optionally the second system and the third system are a same system. In this case, the at least one of video, audio and image analytics is performed using the same system that is used to provide the first indication via the pervasive communication application. Alternatively, the second system and the third system are different systems, and the electronically sensed data is transmitted via a communication network from the location of the third system to the second system. For instance, the second system is a video analytics server or a video analytics server farm. Optionally, the second system performs “cloud” processing to provide video analytics services for a plurality of different third systems.
Referring now to FIG. 5, shown is a method of communicating between a first user and a second user according to an embodiment of the instant invention. At 500 the first user is associated with a first system. At 502 the second user is associated with a second system. At 504, using the first system, a first signal is transmitted from the first user for delivery to the second user via a first communication application. At 506, using an electronic sensor, at least one of video, audio and image data is captured at a location of the second system. At 508 the captured at least one of video, audio and image data is compared with template data relating to the second user. At 510, in dependence upon identifying uniquely the second user based on determining a match between the template data and the at least one of video, audio and image data, a first indication indicative of the first signal is provided to the second user, the first indication being provided via a pervasive communication application that is in execution on the second system, wherein the pervasive communication application is other than the first communication application. Optionally, the attempt to provide the indication to the second user via the pervasive communication application is performed in a cascading manner. For instance, a first attempt is made to provide the indication via a social networking application (such as for instance Facebook®), followed by an attempt using Yahoo mail, followed by an attempt using America Online instant messaging, etc.
Referring now to FIG. 6, shown is a method of communicating between a first user and a second user according to an embodiment of the instant invention. At 600 the first user is associated with a first system. At 602 the second user is associated with a second system. At 604, using a first communication application in execution on the first system, a first signal is transmitted from the first user for delivery to the second user via a second communication application. At 606 at least one of video, audio and image data is captured at a location of the second system. At 608 at least one of video, audio, and image analytics is performed to determine a presence of the second user at the location of the second system. At 610, when the second user is determined to be present at the location of the second system, a first indication indicative of the first signal is provided to the second user, the first indication being provided via a pervasive communication application in execution on the second system, wherein the pervasive communication application is other than the second communication application. Optionally, the attempt to provide the indication to the second user via the pervasive communication application is performed in a cascading manner. For instance, a first attempt is made to provide the indication via a social networking application (such as for instance Facebook®), followed by an attempt using Yahoo mail, followed by an attempt using America Online instant messaging, etc.
Referring now to FIG. 7, shown is a method of communicating between a first user and a second user according to an embodiment of the instant invention. At 700 the first user is associated with a first system. At 702 the second user is associated with a second system. At 704, using a first communication application that is in execution on the first system, a first signal is transmitted from the first user for delivery to the second user via a second communication application. At 706 at least one of video, audio and image data are captured at a location of the second system. At 708 the captured at least one of video, audio and image data are transmitted from the second system to a third system via a communication network. At 710, using the third system, at least one of video, audio, and image analytics of the at least one of video, audio and video data is performing to determine a presence of the second user at the location of the second system. At 712, when the second user is determined to be present at the second system, a first indication indicative of the first signal is provided to the second user, the first indication being provided via a pervasive communication application that is in execution on the second system, wherein the pervasive communication application is other than the second communication application. Optionally, the attempt to provide the indication to the second user via the pervasive communication application is performed in a cascading manner. For instance, a first attempt is made to provide the indication via a social networking application (such as for instance Facebook®), followed by an attempt using Yahoo mail, followed by an attempt using America Online instant messaging, etc.
According to the methods of FIGS. 3 to 7, at least one of video, audio, and image analytics of sensed data is performed to identify the second user uniquely. In one implementation, the sensed data is compared with template data associated with each of a group of individuals to result in a 1 of N identification search. Optionally, N is less than 100. Further optionally, N is less than 10.
Further, the first communication application typically, but not necessarily exclusively, is the same as or similar to the second communication application. For instance, in one implementation both of the first communication application and the second communication application is the Skype® software application. In another implementation, the first communication application is a first email application such as for instance “Mail” for the Mac OS X operating system, and the second communication application is a second email application such as for instance “Thunderbird” for the Mac OS X. Of course, alternatively both of the first communication application and the second communication application is the same email application, such as for instance “Mail” for the Mac OS X operating system. A person having ordinary skill in the art may readily envisage various other suitable combinations of the first and second communications applications.
Numerous other embodiments may be envisaged without departing from the scope of the invention.
