Furthermore, enhanced network capabilities to perform various advanced operations may provide additional benefits to device users, but may also place increased demands on the control and management of various network components. For example, an enhanced electronic network that effectively supports streaming video may benefit from an efficient implementation because of the large amount and complexity of the digital data involved.
Due to growing demands on network resources and substantially increasing data magnitudes, it is apparent that developing new techniques for implementing and utilizing electronic networks is a matter of concern for related electronic technologies. Therefore, for all the foregoing reasons, developing effective techniques for implementing and utilizing electronic networks remains a significant consideration for designers, manufacturers, and users of contemporary electronic devices.
SUMMARY
In accordance with the present invention, a system and method for effectively implementing a personal assistant in an electronic network are disclosed. In one embodiment, the personal assistant (PA) is initialized on a main personal computer (main PC) that is connected to an electronic network that also includes one or more additional local devices. During initialization, various input devices are typically initialized, and user metadata, command metadata, and content metadata are loaded.
The personal assistant initially detects a user by utilizing any effective means. For example, the personal assistant may utilize various motion detection, facial recognition, and voice recognition techniques. The personal assistant then executes one or more recognition algorithms to investigate the identity of the detected user. The personal assistant then determines whether the detected user is affirmatively recognized. In accordance with the present invention, the personal assistant may detect and recognize a user at the main PC. In addition, the personal assistant may also detect and recognize a user remotely through any of the local devices.
If the detected user is recognized, then the personal assistant loads a corresponding user profile from stored user metadata. In addition, the personal assistant loads the particular user screen and menu to display a personal assistant user interface (PA UI) that is associated with the recognized user. The personal assistant then waits for a user command to be issued by the current user.
However, if the detected user is not recognized by the personal assistant, then the personal assistant creates a new user in the user metadata. In certain embodiments, a new user may only be created if the new user has appropriate security authorization. The personal assistant then loads a default user screen and menu to display a PA UI to the newly-created user. The personal assistant then waits for a user command to be issued by the current user.
The user provides a command to the personal assistant by utilizing any effective means. For example, the user may provide a verbal command to the personal assistant. In response, the personal assistant accesses stored command metadata to perform a command recognition procedure. The personal assistant determines whether the command is affirmatively recognized. If the command is not recognized, then the personal assistant communicates with the user to interactively perform a command clarification procedure. However, if the command is recognized, then the personal assistant determines whether the current command involves content. If the command does not involve content, then the personal assistant executes the command, and updates the user metadata and the command metadata to reflect executing the command. If it is unclear whether the command involves content, then the personal assistant questions the user regarding the content, and receives the user's response.
However, if the command does involve content, then the personal assistant accesses appropriate user metadata and content metadata. The personal assistant then determines whether the particular content is currently available from an accessible content source. In certain embodiments, the personal assistant may determine whether the content is stored on a local device, whether the content is available from a remote device, or whether the content is a live TV program.
If the content is not available from a content source, then the personal assistant questions the user regarding the content, and receives the user's response. However, if the content is available from a content source, then the personal assistant accesses the content. The personal assistant next performs a target identification procedure to identify a target location or target device for receiving the content.
The personal assistant then streams the content to the identified target location or target device. Finally, the personal assistant completes executing the current command if any unfinished command tasks remain, and also updates the user metadata and the command metadata to reflect executing the command. The personal assistant command procedure may then terminate. The present invention therefore provides an improved system and method for effectively implementing a personal assistant in an electronic network.

Referring now to FIGS. 7A-7B, a flowchart of method steps for utilizing a personal assistant to perform a command execution procedure is shown, in accordance with one embodiment of the present invention. The FIG. 7 example is presented for purposes of illustration, and in alternate embodiments, the present invention may utilize steps and sequences other than certain of those steps and sequences discussed in conjunction with the FIG. 7 embodiment.
In step 714 of the FIG. 7A embodiment, a personal assistant (PA) 316 is initialized on a main personal computer (main PC) 114 that is connected to an electronic network 110 that also includes one or more additional local devices 122 (FIG. 1). During initialization, various input devices are typically initialized, and user metadata 612, command metadata 618, and content metadata 616 (FIG. 6) are loaded.
In step 718, the personal assistant 316 detects a user by utilizing any effective means. For example, the personal assistant 316 may utilize various motion detection, facial recognition, and voice recognition techniques. In step 722, the personal assistant 316 executes one or more recognition algorithms to determine the identity of the detected user. In accordance with the present invention, the personal assistant 316 may detect and recognize a user near main PC 114. In addition, the personal assistant 316 may also detect and recognize a user remotely through any of the local devices 122 (FIG. 1). In step 726, the personal assistant 316 determines whether the detected user is affirmatively recognized.
If the detected user is recognized, then in step 730, the personal assistant 316 loads a corresponding user profile from stored user metadata 612. In step 734, the personal assistant 316 loads the particular user screen and menu to display a personal assistant user interface (PA UI) that is associated with the recognized user. In step 738, the personal assistant 316 then waits for a user command to be issued by the current user.
If the detected user is not recognized in foregoing step 726, then in step 742, the personal assistant 316 creates a new user in user metadata 612. In certain embodiments, a new user may only be created if the new user has appropriate security authorization. In step 746, the personal assistant 316 loads a default user screen and menu to display a personal assistant user interface (PA UI) to the newly-created user. In step 738, the personal assistant 316 then waits for a user command to be issued by the current user.
In step 750, the user provides a command to the personal assistant 316 by utilizing any effective means. For example, the user may provide a verbal command to the personal assistant 316. In step 754, the personal assistant 316 accesses stored command metadata 618 to perform a command recognition procedure. In step 758, the personal assistant 316 determines whether the command is affirmatively recognized. If the command is not recognized, then in step 762, the personal assistant 316 communicates with the user to interactively perform a command clarification procedure, as further discussed below in conjunction with FIG. 8. However, if the command is recognized in foregoing step 758, then the FIG. 7A process advances to step 766 of FIG. 7B through connecting letter “A.”
In step 766, the personal assistant 316 determines whether the current command involves content. If the command does not involve content, then in step 770, the personal assistant 316 executes the command, and updates the user metadata 612 and the command metadata 618 to reflect executing the command. In step 766, if it is unclear whether the command involves content, then in step 798, the personal assistant 316 questions the user regarding the content, and receives the user's response. The FIG. 7B process may then repeat itself with this new information from the user.
In step 766, if the command does involve content, then in step 798, the personal assistant 316 accesses appropriate user metadata 612 and content metadata 616. In steps 778. 782, and 786, the personal assistant 316 determines whether the particular content is currently available from an accessible content source. In particular, the personal assistant 316 determines whether the content is stored on a local device 122 or main PC 114 (step 778), whether the content is available from a remote device 126 (step 782), or whether the content is a live TV program (step 786).
If the content is not available from a content source, then in step 798, the personal assistant 316 questions the user regarding the content, and receives the user's response. The FIG. 7B process may then repeat itself with this new information from the user. However, if the content is available from a content source, then in step 790, the personal assistant 316 accesses the content. In step 794, the personal assistant 316 performs a target identification procedure to identify a target location or target device, as further discussed below in conjunction with FIG. 9.
In step 796, the personal assistant 316 streams the content to the identified target location or target device. Finally, in step 770, the personal assistant 316 completes executing the current command if any unfinished command tasks remain, and also updates the user metadata 612 and the command metadata 618 to reflect executing the command. The FIG. 7 procedure may then terminate. The present invention therefore provides an improved system and method for effectively implementing a personal assistant in an electronic network.
Referring now to FIG. 8, a flowchart of method steps for performing a command clarification procedure is shown, in accordance with one embodiment of the present invention. In certain embodiments, the FIG. 8 procedure may correspond to step 762 of foregoing FIG. 7A. The FIG. 8 example is presented for purposes of illustration, and in alternate embodiments, the present invention may utilize steps and sequences other than certain of those steps and sequences discussed in conjunction with the FIG. 8 embodiment.
In step 814 of the FIG. 8 embodiment, the personal assistant 316 performs one or more appropriate command recognition algorithms upon an unrecognized command. In step 818, the personal assistant 316 determines whether a command candidate can be located that is similar to a command from command metadata 618 (FIG. 6) or that may be an incomplete portion of a known command. In step 822, the personal assistant 316 offers the command candidate to the user by utilizing any effective means.
In step 826, the personal assistant 316 determines whether the user accepts the command candidate. If the user fails to accept the command candidate, then in step 830, the personal assistant 316 asks the user one or more clarification questions. Finally, in step 834, the user provides an appropriate clarified command to the personal assistant 316, and the FIG. 8 procedure may then terminate.
Referring now to FIG. 9, a flowchart of method steps for performing a target identification procedure is shown, in accordance with one embodiment of the present invention. In certain embodiments, the FIG. 9 procedure may correspond to step 794 of foregoing FIG. 7B. The FIG. 9 example is presented for purposes of illustration, and in alternate embodiments, the present invention may utilize steps and sequences other than certain of those steps and sequences discussed in conjunction with the FIG. 9 embodiment.
In step 914 of the FIG. 9 embodiment, the personal assistant 316 determines whether the current command identifies a target, such as a target location, main PC 114, or a local device 122. If the command does not identify a target, then in step 918, the personal assistant 316 may select a default target (e.g. main PC 114). In certain embodiments, the personal assistant 316 may automatically determine a target device/location by analyzing a source device identifier corresponding to where the current command originated.
In step 914, if it is unclear whether the command identifies a target, then in step 922, the personal assistant 316 questions the user regarding the target, and receives the user's response. The FIG. 9 process may then repeat itself with this new information from the user. In step 914, if the command does specify a target device/location, then in step 926, the personal assistant 316 accesses appropriate user metadata 612 and network device metadata 620. In step 930, the personal assistant 316 determines whether the specified target device/location is found in the stored metadata.
If the target device/location is not found in the metadata, then in step 922, the personal assistant 316 questions the user regarding the target, and receives the user's response. The FIG. 7B process may then repeat itself with this new information from the user. However, if the target device/location is found in the metadata, then in step 934, the personal assistant 316 selects the located target device/location, and the FIG. 9 procedure may then terminate.
Referring now to FIG. 10, a block diagram illustrating the utilization of a personal assistant 316 through a local network device 122 is shown, in accordance with one embodiment of the present invention. The FIG. 10 embodiment is presented for purposes of illustration, and in alternate embodiments, personal assistant may be utilized using various components and configurations in addition to, or instead of, those components and configurations discussed in conjunction with the FIG. 10 embodiment.
In the FIG. 10 embodiment, personal assistant 316 (FIG. 4) is running on main PC 114. In accordance with the present invention, personal assistant 316 may transfer a copy of its personal assistant user interface (PA UI) to any electronic device in the user's network. In the FIG. 10 embodiment, local device 122 displays a copy of the PA UI to a system user 1014. Accordingly, main PC 114 may communicate with system user 1014 through communication paths 1026 and 1030 by using local device 122 as an intermediary. Similarly, system user 1014 may communication with main PC 114 through communication paths 1018 and 1022 by using local device 122 as an intermediary. The present invention therefore provides an electronic personal assistant for any desired type of operating environment. The personal assistant advantageously creates a personal assistant user interface that is supported with artificial intelligence to manage individuals' daily activities by utilizing any of the electronic devices within the operating environment.
The present invention has been explained above with reference to certain embodiments. Other embodiments will be apparent to those skilled in the art in light of this disclosure. For example, the present invention may readily be implemented using configurations and techniques other than those described in the embodiments above. Additionally, the present invention may effectively be used in conjunction with systems other than those described above. Therefore, these and other variations upon the discussed embodiments are intended to be covered by the present invention, which is limited only by the appended claims.
