This Summary section is provided merely to introduce certain concepts and not to identify any key or essential features of the claimed subject matter. Other features of the inventive arrangements will be apparent from the accompanying drawings and from the following detailed description.
The patent or application file contains at least one drawing executed in color. Copies of this patent or patent application publication with color drawing(s) will be provided by the Office upon request and payment of the necessary fee.
The inventive arrangements are illustrated by way of example in the accompanying drawings. The drawings, however, should not be construed to be limiting of the inventive arrangements to only the particular implementations shown. Various aspects and advantages will become apparent upon review of the following detailed description and upon reference to the drawings.
While the disclosure concludes with claims defining novel features, it is believed that the various features described herein will be better understood from a consideration of the description in conjunction with the drawings. The process(es), machine(s), manufacture(s) and any variations thereof described within this disclosure are provided for purposes of illustration. Any specific structural and functional details described are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the features described in virtually any appropriately detailed structure. Further, the terms and phrases used within this disclosure are not intended to be limiting, but rather to provide an understandable description of the features described.
This disclosure relates to computer-based interactive applications, and more particularly, to interactive applications that use digital humans. In accordance with the inventive arrangements described herein, example methods, systems, and computer program products are provided that are capable of developing and rendering an interactive digital human having human-like attributes. As defined herein, “digital human” means is a computer-generated entity that in a visual rendering has a human-like appearance and includes, or is coupled to, an artificial intelligence (AI) for interpreting user input and responding to the input in a contextually appropriate manner. The AI can be accessed by the digital human via an API that connects to services either internal to the digital human or external to the digital human. The digital human is capable of interacting intelligently with a human user, developing a human-like memory, and displaying human-like behaviors, emotions, and personality.
One aspect of the inventive arrangements disclosed is a digital human development platform capable of generating a broadcast-ready digital human in response to and in accord with user specifications. The tool enables the user to specify a dialogue for the digital human to vocalize and behaviors for the digital human to display while engaged in the dialogue. As defined herein, “dialogue” means communication between a digital human and at least one actual human, in which the digital human communicates by voice, text, or gesture, regardless of whether an actual human communicates. In some scenarios, the dialogue is a two-way communication with, for example, the digital human answering or providing information in response to an actual human's query. Indeed, as disclosed herein, the digital human can engage in an interactive exchange or conversation with one or more actual humans. In other scenarios, the dialogue is a one-way dialogue or soliloquy, with the digital human providing instructions or information. In one aspect, the providing of information may be performed in response to detecting the presence of a human but without an express communication of the actual human. In each scenario, however, the digital human not only communicates in words but also in behavior, such as facial expressions, eye movements, and/or gestures that enhance the human-like quality of the dialogue.
The development tool enables the user to fine-tune movements, gestures, and facial expressions for the digital human to display while engaged in the dialogue. In contrast to conventional development tools, the inventive arrangements provide a unified platform combining capabilities for generating an interactive dialogue, digital human behaviors corresponding to the dialogue, and the background against which the digital human is visually rendered.
Another aspect of the inventive arrangements is a digital human interactive platform capable of generating the digital human, which in accordance with a user-specified dialogue, engages in an intelligent conversation (e.g., question-and-response dialogue) and displays behaviors (e.g., facial expressions, gestures) that mimic moods, emotions, and memory of an actual human.
Still another aspect is a digital human display assembly. In certain aspects, the digital human display assembly can provide a life-size image of the digital human. One or more sensors (e.g., camera, microphone, fingerprint reader, card reader) can be mounted to the digital human display assembly. The digital human may interact with an actual human based on sensor data generated by the sensor(s). A Light Emitting Diode (LED) array also can be connected to the digital human display assembly.
Yet another aspect is a communicative light system that activates and controls an LED array connected to the digital human display assembly. The communicative light system is capable of controlling the LED array to further communicate information to the actual human.
Further aspects of the inventive arrangements are described below in greater detail with reference to the figures. For purposes of simplicity and clarity of illustration, elements shown in the figures are not necessarily drawn to scale. For example, the dimensions of some of the elements may be exaggerated relative to other elements for clarity. Further, where considered appropriate, reference numbers are repeated among the figures to indicate corresponding, analogous, or like features.
DHDP 100, in response to system user input 108, is capable of generating scene data 110 that can be loaded on and executed by a separate device (e.g., local or cloud-based server). Executing scene data 110, the separate device visually and audibly presents a digital human on the display. The digital human engages in a dialogue with an individual who, positioned adjacent the display, interacts with the digital human.
Scene data 110, in some arrangements, comprise instructions that control the actions of the device having or operatively coupled with the display with which the digital human is visually and audibly presented. In other arrangements, scene data 110 comprise one or more audio-visual files that execute on the device. In each of the various arrangements, executing scene data 110 on the device enables the digital human to engage in the interactive dialogue with the individual adjacent the display on which the digital human is presented. The digital human vocalizes information, provides instructions, responds to queries, or otherwise interacts with the individual in the context of a specific dialogue. While engaged in the dialogue, the digital human expresses mood and emotion through voice inflections, facial expressions, bodily gestures, and the like—all of which are aptly suited for the specific context at each stage of the dialogue. The moods and emotions demonstrated by the digital human are responsive to the words and/or actions of the individual who engages in the dialogue with the digital human. The words and/or actions of the individual engaged in dialogue can be detected by a microphone and/or camera operatively coupled with the display on which the digital human appears. The digital human's spoken words and behavior, generated with the previously generated scene data 110, are responsive to the detected words and/or actions of the individual.
Scene data 110 is generated in response to, and based on, system user input 108 received by DHDP 100 via a user interface generated by user interface generator 102. In certain arrangements, user interface generator 102 generates a graphical user interface (GUI).
With digital human selector 104, the system user can select the digital human and set a resolution for the image of the digital human. The digital human selected can be chosen from multiple, preconfigured digital humans each having a distinct look, or visual appearance. The preconfigured digital humans can be electronically stored, for example, in database 112. Database 112, in some arrangements, is stored on the same device (e.g., computing node) in which DHDP 100 is implemented. In other arrangements, database 112 is stored on a separate device, such as a remote server (e.g., a cloud-based server).
Digital human editor 106 receives system user input 108 via the user interface generated by user interface generator 102. System user input 108 can specify a dialogue for the digital human, as well as one or more behaviors of the digital human corresponding with one or more portions of the dialog. Digital human editor 106 can align the dialogue and one or more behaviors corresponding to the one or more portions of dialog. Scene data 110 is generated by digital human editor 106 merging the one or more behaviors with one or more portions of the dialogue based on times of the one or more behaviors and the one or more portions of the dialog on a timeline.
Specific aspects of the dialogue and corresponding one or more behaviors can be generated based on system user input 108 to digital human editor 106. System user input 108 can specify attributes that contribute to the “look” and “mood,” wherein the look is defined by facial features of the digital human and “mood” corresponds to the digital human's facial expressions.
In certain embodiments, digital human editor 106 includes voice editor 114, dialogue editor 116, and behavior editor 118. Voice editor 114 enables the user to select a voice type (e.g., sympathetic, stern, business) and/or tone.
Dialogue editor 116 enables the system user to specify specific words to be spoken by the digital human in response to one or more predetermined cues during an interactive dialogue with an individual. For example, in an airport scenario, the interactive dialogue may entail the digital human providing flight information to an individual in response to the individual specifying a desired destination. In a shopping scenario, for example, the dialogue may include the digital human recommending a particular type or brand of cosmetic in response to an individual's request for makeup information. In various other scenarios, the dialogue may comprise an instructional, informational, or other soliloquy type vocalization (e.g., a news presentation) solely by the digital human without either input or interaction with a viewing user who is watching and/or listening to the digital human.
Using dialogue editor 116, the system user is able to specify specific speech attributes of the digital human when speaking the dialogue. The speech attributes can include, for example, stress on certain words for emphasis, word inflections, tone of voice, and the like. The dialogue specified by system user input 108 is aligned on a timeline by digital human editor 106. Dialogue editor 116 enables the user to specify, based on the timeline, the duration and speed of the dialogue.
Optionally, dialogue editor 116 can enable the user to select one of a plurality of different languages for the digital human to speak. DHDP 100 can include a translator (not explicitly shown) that translates user input (text and/or voice-to-text) in one language to another language.
Behavior editor 118 enables the system user to specify the behaviors in which the digital human engages while vocalizing the dialogue and/or at other times when not engaged in dialog (e.g., while awaiting input from a user). Behaviors can include, for example, movements of the digital human's mouth (e.g., smile, frown, moving in coordination with speaking), eyes (e.g., looking up, down, left, right, or forward), head (e.g., turning, tilting to the side), and/or hand gestures. The facial features of the digital human can include, for example, a pleasant smile when conveying a greeting, a furrowed brow connoting concern or intense interest when receiving information from an individual, a wide-eyed look to denote surprise, or other expression given a particular interaction with the individual. In different arrangements, each distinct behavior can be implemented by preconstructed animated video of the behavior and/or computer-executable instructions (software code) that executes on a computer system integrated in or operatively coupled with the display that presents the digital human.
In addition to dialogue track 208, GUIs 200a, 200b, 200c, and 200d also include behavior track 218, which enables the system user to track user-specified behaviors (described below) on timeline 210, which is common to both the dialogue track 208 and behavior track 218. Fine tuning track 220 enables the system user to fine tune the user-specified dialogue on dialogue track 208. Fine tuning track 222 enables the system user to fine tune (also described below) the user-specified behaviors on behavior track 218. Aligning the dialogue and one or more corresponding behaviors to common timeline 210 enables the system user to visualize the overlap between the two, essentially allowing the system user to see what behavior the digital human performs as the digital human vocalizes specific portions of the dialogue. The alignment further enables the system user to fine tune the digital human's behaviors with words spoken so that each word has just the right emphasis or inflection, and so that each word spoken occurs with just the right tone, emotion, gesture, facial expression, and/or eye movement.
In one or more examples, the system user may initiate playback of the digital human to audition the dialog rendering in combination with the specified behaviors. The digital human may vocalize the dialog in combination with animating the behaviors in the window displayed within the example GUIs while a play head advances through the timeline showing the exact position in time on the timeline during the auditioning or playback of the dialog and behaviors by the digital human.
At block 502, the system enables a system user to select a digital human. The system, at block 504, can receive user input specifying a dialogue for the digital human and one or more behaviors for the digital human. The one or more behaviors correspond with one or more portions of the dialog on a common timeline. At block 506, the system can generate scene data by merging the one or more behaviors with one or more portions of the dialogue based on times of the one or more behaviors and the one or more portions of the dialog on the common timeline.
The system, in certain embodiments, enables the system user to select a visual representation of the digital human from a plurality of visual representations corresponding to different digital humans electronically stored in a database communicatively coupled with the system. In certain arrangements, different digital humans can be electronically stored on a remote server or other computing node communicatively coupled (e.g., via a data communications network) with the system. Optionally, the system also can enable the system user to select a voice type corresponding to the digital human for audibly rendering the dialogue specified by the system user input.
The system also optionally can enable the system user to select a language corresponding to the digital human for audibly rendering the dialogue on a display device. The system, moreover, can include a translator to automatically convert the dialogue into the selected language in the event that the dialogue based on system user input is in a different language than that selected.
In certain embodiments, the merging performed with the system comprises determining individual time segments of the timeline, during which distinct portions of the dialogue are rendered, and editing at least one of the one or more behaviors within each of the individual time segments. The one or more behaviors can include one or more facial expressions rendered by the digital human. Each facial expression may be timed based on the timeline to correspond to a time interval during which a select portion of the dialogue occurs or an absence of dialogue between two consecutive portions of the dialogue occurs. The one or more behaviors additionally, or alternatively, can include one or more gestures made by the digital human, each gesture corresponding to a select portion of the dialogue or an absence of dialogue between two consecutive portions of the dialogue.
In certain embodiments, the system enables the system user to edit the dialogue. The editing can modify words, phrases, and the like according to the system user's specification. The editing can provide an inflection, a stress, a speech rate, and/or a tone of one or more words of the dialogue. In certain other embodiments, the system in response to system user input can generate a background against which the digital human appears when visually rendered on a display. The system can, in response to system user input, position the digital human against the background when the digital human is presented on the display.
Illustratively, DHIP 600 includes interactive application 602, foundry 604, vault 606, digital human database 608, user database 610, and real-time reality-based response (R3) sub-system 612. Foundry 604, vault 606, digital human database 608, user database 610, and R3 sub-system 612 can each be implemented in hardware (e.g., dedicated hardwired circuitry), software (e.g., program code executed by one or more processors), or a combination thereof. For example, DHIP 600 in certain embodiments is implemented in a device, such as device 2400. Accordingly, in certain embodiments, DHIP 600 comprises program code that is electronically stored in a memory, such as memory 2404, and executes on one or more processors, such as processor(s) 2402 of device 2400 (
Interactive application 602 comprises a front end of DHIP 600. Supported by the other elements of DHIP 600—foundry 604, vault 606, digital human database 608, user database 610, and R3 sub-system 612—interactive application 602 is the vehicle or interface via which the digital human generated by DHIP 600 interacts with a human individual, the user. Thus, the user sees, hears, and speaks with the digital human through interactive application 602. In various arrangements, interactive application 602 is integrated with the other elements of DHIP 600 in the same device, such as a kiosk display, computer (e.g., desktop, laptop), or mobile device (e.g., smartphone). In other arrangements, interactive application 602 can be implemented, for example, in Java Script, HTML, or other platform-agnostic software that executes on a display kiosk, computer, smartphone, or other device which operatively couples with a local, remote, or cloud-based server in which foundry 604, vault 606, digital human database 608, user database 610, and R3 sub-system 612 are implemented.
Foundry 604 electronically stores data, such as machine-executable instructions and/or video files, corresponding to attributes described above pertaining to the digital human. Thus, attributes of the digital human generated with data electronically stored in foundry 604 can include the digital human's facial features, mood, tone of voice, language, and the like. Vault 606 electronically stores related meta-data pertaining to the digital human. Digital human database 608 provides a list or menu of different digital humans available for engaging in an interactive dialogue. User database 610 electronically stores data specific to a user that engages in a dialogue with the digital human. As described in greater detail below, user data electronically stored in user database 610 can include, for example, certain user preferences and/or information that the digital human references during an on-going dialogue or in separate dialogues at different times.
In certain arrangements, user data can be data that relates to a one-time interaction between the user and the digital human. An example one-time interaction is a scenario in which the user approaches a kiosk capable of displaying the digital human agent, which is configured to respond to a user request for information. The information request, for example, can be a request for flight information if the digital human is displayed on an airport kiosk. For example, the information request can be a request for information concerning a product if the digital human is displayed on or adjacent a product counter. User database can cache information as the dialogue proceeds. For example, in a scenario described below in which the digital human engages with the user in a dialogue concerning makeup, the digital human asks what the user's skin tone is. The user's response is cached in user database 610 and referenced by the digital human as the dialogue proceeds as the digital human describes different aspects of different products suited to the user's specific skin tone.
In other arrangements, user database 610 can electronically store data pertaining to a user who repeatedly engages in one or more dialogues with the digital human. For example, the user data can comprise dates and scheduling information, based on which the digital human conveys at predetermined time an unsolicited reminder to the user. Scene data 110, for example, can generate a dialogue in which the digital human, based on user data electronically stored in user database 610, reminds the user that the user has an important appointment scheduled for a certain time on a specific day. If the DHIP 600 is configured to also interact with other devices (e.g., appliances) through an Internet-of-Things (IoT) architecture, for example, the dialogue can entail the digital human asking the user at a prespecified time electronically stored in user database 610 whether the user is ready for the digital human to start a coffee maker to make the user's morning coffee.
R3 sub-system 612 comprises the back end of DHIP 600. R3 sub-system 612 generates the visual and audible presentation of the digital human (e.g., on a kiosk display, smartphone, or computer). In rendering the digital human as the digital human engages in an interactive dialogue with an individual through interactive application 602, R3 sub-system 612 executes scene data 110 generated with DHDP 100 as described above.
R3 sub-system 612 illustratively includes neural rendering engine 614, xform 616, and audio-to-keypoints (A2KP) 618. Neural rendering engine 614 renders the visual images and audible speech of the digital human based on scene data 110, generating the audio and images in each frame rendered on the display. The fine tuning of the digital human's dialogue and/or behavior (e.g., facial expression, eye movement, gestures) done with digital human editor 106 is implemented by xform 616. Xform 616 can run on top of A2KP 618. A2KP 618 produces keypoints from audio rendered by an electronically stored audio file or text converted to audio. Keypoints are visual representations of the digital human, such as facial features. Keypoints can provide anchors for the digital human's facial expressions, which can be driven by audio or behavior of the digital human. Keypoints can have a one-to-one correspondence with an output frame. The digital human's behavior can be described as, or correspond to, a sequence of keypoints. Accordingly, keypoints can be created for distinct image frames that correspond to portions of audio for rendering the audiovisual display of the digital human. For example, a keypoint can correspond to the digital human's pursing of the lips in saying a word like “Hello” or moving the eyes to look in a certain direction giving a greeting.
In an interactive exchange of dialogue between the digital human and a user, interactive application 602 can determine a contextual response to a user input. The contextual response can be dictated in accordance with a dialogue prespecified by scene data 110 generated by DHDP 100 and loaded to a device that implements interactive application 602. The user input can be a request or a question. For example, the user can request flight information or ask a question about a certain type of product. The user input can be in the form of text, voice, or gesture. In certain arrangements, the user input can be received from a user device such as a computer or smartphone that is communicatively coupled (e.g., via a wired or wireless connection) through a voice or data communication network with a device (e.g., local or cloud-based server) in which DHIP 600 is implemented. In some arrangements, interactive application 602 can execute on the user's device and can communicatively couple with the other elements (foundry 604, vault 606, digital human database 608, user database 610, and R3 sub-system 612) of DHIP 600, which runs on a device, such as a local or cloud-based server. In other arrangements, interactive application 602 executes on a display structure having processing capabilities and that implements the other elements of DHIP 600 or operatively couples with a device such as a local or cloud-based server that implements the other elements of DHIP 600. The display structure in various arrangements can include various operative elements (e.g., camera, microphone, scanner) for receiving the user input.
R3 sub-system 612 generates a digital human based on the data electronically stored in foundry 604. Foundry 604 stores the digital artifacts required to represent a digital human such as machine learning models for different components (e.g., neural rendering engine, xform). Depending on the nature of the contextual response, the digital human also can be generated using data electronically stored in vault 606, which stores information corresponding to user-digital human interactions including user preferences and past interactions to further personalize the interactions. The contextual response to the user input is conveyed by a digital human. In accordance with a dialogue specified by scene data 110, the digital human conveys the contextual response with one or more behaviors (e.g., facial expression, eye movement, gesture) that correspond to the textual response. Optionally, R3 sub-system 612 can include digital human database 608 to electronically store data for generating different digital humans for conveying the contextual response, and user database 610 to electronically store other user-specific data.
Optionally, as illustrated in
Interactive dialogues between a digital human and a user can be conducted via speech, text, or a combination of both. Voice-based interactive dialogues with a digital human can be conducted, for example, by the user speaking to a microphone-endowed digital human display assembly (described below) or computer or another microphone-endowed device (e.g., smartphone). Alternatively, or additionally, an interactive dialogue can be conducted by text messaging over a device (e.g., smartphone, laptop) or touching the screen of a digital human display assembly. Using camera-endowed device, an interactive dialogue can be conducted by gestures (e.g., sign language) between the digital human and user. In various arrangements, an interactive dialogue can be conducted via voice, text, and/or visual gesturing.
At block 1102, the interactive system determines a contextual response to a user's input. The user input can comprise audible input. The interactive system, in certain arrangements, can capture the audible input using a microphone operatively coupled with the interactive system. The interactive system can determine from the audible input one or more words spoken by the user. Additionally, or alternatively, the user input can comprise visual input. In certain arrangements, the interactive system can capture visual input using a camera operatively coupled with the interactive system. Based on the visual input, the interactive system can determine one or more body movements by the user. The interactive body movements can include facial expression and gestures. In certain arrangements, the interactive system can infer a mood (e.g., surprise, joy, anger) of the user based on user input (e.g., spoken or written words, facial expressions, gestures).
At block 1104, the interactive system generates a digital human, and at block 1106, conveys with the digital human the contextual response. The contextual response can be conveyed by the digital human to the user in real time. The interactive system can configure the digital human to convey the contextual response with a predetermined behavior corresponding to the contextual response. The predetermine behavior can convey a mood or emotion of the digital human and can include one or more facial expressions, eye movements, and/or gestures.
In some embodiments, rectangular display panel 1202 and glass covering 1204 are enclosed within frame 1206. Frame 1206 can include top portion 1208, side portions 1210a and 1210b, and bottom portion 1212.
Illustratively, digital human display assembly 1200 also includes base 1214. Base 1214 is capable of supporting frame 1206, as well as rectangular display panel 1202 and glass covering 1204 enclosed therein, in an upright position. Base 1214 illustratively comprises front portion 1216a and back portion 1216b. Backplane 1218 can extend upward from back portion 1216b of base 1214. Horizontal support beams 1220 can connect to rectangular display panel 1202 and backplane 1218 to provide added support.
Digital human display assembly 1200 also includes LED array 1222, comprising multiple LEDs. LED array 1222, as described in greater detail below, is capable of creating visual effects, which among other functions can communicate to the user expressions, emotions, and/or reactions of the digital human displayed interactively on rectangular display panel 1202. Illustratively, LED array 1222 is positioned on one or both sides (only one of which is in view) of digital human display assembly 1200. In other arrangements, LED array 1222 can be positioned along the top border of digital human display assembly 1200. In still other arrangements, LED array 1222 can comprise LEDS positioned along the top border and one or both sides. The bezel width of the LED array can be selected so as to provide greater screen space on rectangular display panel 1202. For example, with a side-positioned LED array, the bezel width can be minimized for maximum screen space.
Digital human display assembly 1200 can include one or more speakers (not explicitly shown). The one or more speakers can be positioned behind sound radiation structure 1224. In some arrangements, sound radiation structure 1224 is formed in the base 1214, specifically in the front portion 1216a. In other arrangements, sound radiation structure 1224 is formed between the base 1214 and a bottom portion of glass covering 1204. Sound radiation structure 1224 in certain embodiments can be positioned within groove 1226 between base 1214 and glass covering 1204. Referring additionally to partial cross-section 1300 of digital human display assembly 1200 in
One or more cameras 1228 can be attached to connector 1230, which illustratively is mounted on frame 1206. Camera(s) 1228 can capture images, movements, facial expressions, and gestures of an individual who interacts face-to-face with the digital human rendered on rectangular display panel 1202. One or more other sensors (not explicitly shown) can also be connected to fame 1206. The sensors can include, but are not limited to, a microphone, a fingerprint sensor, a card reader (e.g., capable of reading a magnetic strip and/or “chip” type of card), and/or near-field communication (NFC) sensor.
In certain arrangements, a computer 1232 operatively couples with rectangular display panel 1202. The computer 1232 can store in memory scene data 110, and one or more processors of computer 1232 can execute scene data 110 (e.g., machine-executable instructions and/or video files) for generating the digital human which exhibits pre-specified behaviors while engaging in an interactive dialogue with a user. Computer 1232 is able to process in real time vocal input of a user. Computer 1232 can also process in real time images of the user's movements, facial expressions, and/or gestures using object recognition. As described in greater detail below, the content and tone of the user's verbal input, as well as appearance and movements, can be processed and used to control LED array 1222. Computer 1232 can be positioned within expanded bottom portion 1234 formed in back portion 1216b of base 1214.
In certain embodiments, digital human display assembly 1200 does not include frame 1206. Instead, rectangular display panel 1202 is covered by a rimless glass covering, which extends over the front side of the rectangular display panel 1202.

CLS 1800 illustratively includes contextualizer 1802, communicative lighting sequence determiner 1804, and LED array activator 1806. Contextualizer 1802, communicative lighting sequence determiner 1804, and LED array activator 1806 can each be implemented in hardware (e.g., dedicated hardwired circuitry), software (e.g., program code executed by one or more processors), or a combination thereof. For example, CLS 1800 in certain embodiments is implemented in a computer system, such as computer system 2312 (
Contextualizer 1802 is capable of determining certain aspects of a user who intends to interact, or is interacting, with a digital human displayed on digital human display assembly 1200. CLS 1800 can determine aspects of the user based on signals generated by one or more sensors 1808, which operatively couple with contextualizer 1802. Optionally, contextualizer 1802 can additionally, or alternatively, base the determination in whole or in part on user preferences and/or settings electronically stored in database 1810. Database 1810 can be electronically stored on the same device in which CLS 1800 is implemented or on a separate device (e.g., cloud-based server) that connects via a wired or wireless connection with CLS 1800 over a communications network (e.g., the Internet or other data communications network). Additionally, or alternatively, CLS 1800 can select one of a plurality of digital humans electronically stored in digital human database 1812. The digital human selected can be selected based on the user aspect. Digital human database 1812 also can be electronically stored locally or remotely.
Communicative lighting sequence determiner 1804 determines a communicative lighting sequence based on the user aspect. The user aspect can be expressed by a voice signal spoken by the user or a textual input of the user. In some arrangements, as described below, the user aspect can be inferred by a facial expression or gesture of the user. The lighting sequence is directed to the specific user aspect. In various scenarios, the user may wish to obtain information or instructions from the digital human, for example. In other scenarios, the user may wish to engage in a more extensive dialogue (e.g., one-way soliloquy or two-way conversation) with the digital human.
LED array activator 1806 generates the light sequence of an LED array. As noted, the LED array can be an LED array such as LED array 1222 of digital human display assembly 1200.
In some arrangements, the user aspect that is determined by contextualizer 1802 is the user's presence within a predetermined distance of the digital human display assembly to which CLS 1800 is connected. Sensor(s) 1808 can include a motion sensor and/or camera for determining the user's presence (e.g., detecting motion or via object detection that a human being is present). LED array activator 1806 generates a lighting sequence in response to the user's presence. The lighting of the array can indicate the digital human's acknowledgment of the user's presence. Initially, the LED array lighting can indicate that digital human is ready to interact and can change in response to detecting the user's presence. For example, a green color can change to yellow, or one or more blinking LEDs can stop blinking.
In other arrangements, the user aspect is an audible signal voiced by the user. Sensor(s) 1808 can include a microphone that captures the audible signal. Contextualizer 1802 can implement voice recognition to determine, based on audible signals captured, the nature of the intended interaction of the user with the digital human. For example, the audible signal voiced by the user can indicate a request or question posed to the digital human by the user. The audible signal voiced by the user additionally, or alternatively, can be a user response to a question or request posed by the digital human. The communicative lighting sequence determined by communicative lighting sequence determiner 1804 can indicate an acknowledgment that the digital human recognizes the request or question. LED array activator 1806 can initiate the communicative lighting sequence, which can also indicate after the acknowledgement that the request or question is being processed.
Communicative lighting sequence determiner 1804 can determine a different light sequence is needed if the request or question posed by the user, response of the user, is not understood or is incomplete. Accordingly, communicative lighting sequence determiner 1804 can determine a lighting sequence understood by the user to indicate the request or question or response needs to be repeated or rephrased. LED activator 1806 generates the lighting sequence to indicating the user needs to repeat or rephrase the request or question posed or response to the digital human.
In still other arrangements, sensor(s) 1808 can include a camera for capturing images of the user. CLS 1800 can implement one or more recognition algorithms to process images and/or recognize objects and/or persons therein. For example, contextualizer 1802 can determine from an image a facial feature from which CLS 1800 determines that the user is one a limited number of individuals authorized to interact with the digital human. communicative lighting sequence determiner 1804 can determine one lighting sequence to indicate authorization and another to indicate a lack thereof.
Contextualizer 1802, for example, can determine from an image a facial expression of the user. CLS 1800 can implement a recognition algorithm that determines from the facial expression a mood of the user. The mood may be one of satisfaction, frustration, or anger. Communicative lighting sequence determiner 1804 can determine a lighting sequence activated with LED array activator 180 to acknowledge recognition of the user's mood by the digital human.
Communicative lighting sequence determiner 1804 also can determine a lighting sequence that indicates a current status, action, and/or mood of the digital human. LED array activator 1806 generates the determined lighting sequence according to the current status, action, or mood of the digital human. For example, the lighting sequence can indicate a status of the digital human that the digital human is active and/or ready to receive a request or question. The lighting sequence, for example, alternatively can indicate that the digital human is inactive and/or not ready to receive a request or a question. The lighting sequence can indicate a current action of the digital human, such as waiting action when the digital human is waiting for a response or follow-up from the user during an extended interaction. The lighting sequence can indicate a listening action while the digital human is receiving input from the user. The lighting sequence can indicate a speaking or writing action of the digital human as the digital human is responding to a request or a question posed by the user.
The realistic, human-like aspects of the digital human include emotions and mood as well as the digital human's facial expressions. Communicative lighting sequence determiner 1804 in certain arrangements thus determines different lighting sequence that correspond to different moods of the digital human. For example, the digital human's mood can be pleasant upon greeting and/or conversing with the user. Accordingly, the corresponding lighting sequence determined by communicative lighting sequence determiner 1804, for example, can be one of mellow blues or greens with low intensity. To invoke a sense of surprise corresponding to a surprised expression that the digital human can display in response to an incomprehensible user input, for example, the corresponding lighting sequence determined by communicative lighting sequence determiner 1804 can be a bright, flashing orange.
The specific mood of the digital human can be generated, and can change, depending on the mood of the user—a user aspect determined by contextualizer 1802 based, for example, on voice and/or facial recognition or other sensor-generated input. Communicative lighting sequence determiner 1804 also can correlate the lighting sequence with the detected moods, behaviors, and/or gestures of the user, which also determine the mood and expressions exhibited by the digital human in responding to the user. For example, the digital human's mood can be calm and the corresponding lighting sequence soothing (e.g., slowly pulsing blues) to invoke sympathy and understanding in response to an irate or agitated user (e.g., business customer or traveler).
At block 2202, the system determines an aspect of a user based on one or more sensor-generated signals. The system, at block 2204, determines a communicative lighting sequence based on the user attribute, wherein the communicative lighting sequence is configured to communicate to the user a condition of a digital human. At block 2206, the system generates the lighting sequence with an LED array on a digital human display assembly.
In some arrangements, the one or more sensor-generated signals can include a signal generated by a motion sensor indicating that the user is within a predetermined distance of the digital human display assembly. In other arrangements, the one or more sensor-generated signals comprises an image captured by a camera, and the system can determine based on the image a facial feature of the user, the user's facial expression, and/or physical gesture of the user. The one or more sensor-generated signals, in still other arrangements, can comprise an audible signal captured by a microphone, and the system can determine based on the audible signal a request, a question posed, or a response to the digital human by the user.
The lighting sequence initiated by the system can indicate a status of the digital human. The lighting sequence can indicate an active status, a ready status, or an inactive status of the digital human. The lighting sequence can indicate a current action the digital human is engaged in. The action can be a waiting action, a listening action, a receiving action, and/or a speaking action of the digital human. The communicative lighting sequence can indicate a mood of the digital human. The mood of the digital human can be, for example, a neutral mood, a pleasant mood, a joyful mood, a frustrated mood, an angry mood, or a sad mood. As noted above, the digital human's mood can be responsive to the user's mood—a user aspect determinable, for example, based on voice and/or facial recognition, user gestures, or other sensor-generated input. The communicative lighting sequence can be correlated with the mood as part of the expression of the digital human to evoke an appropriate mood in response to the user. For example, the communicative lighting sequence can be one that corresponds to a pleasant greeting upon an initial meeting or final farewell to the user. Or, for example, the communicative lighting sequence can be tailored to a sympathetic or understanding response to an irate or upset user (e.g., customer or traveler).

The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a LAN or a WAN, or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some cases, electronic circuitry including, for example, programmable logic circuitry, an FPGA, or a PLA may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the inventive arrangements described herein.
Certain aspects of the inventive arrangements are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, may be implemented by computer readable program instructions, e.g., program code.
These computer readable program instructions may be provided to a processor of a computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. In this way, operatively coupling the processor to program code instructions transforms the machine of the processor into a special-purpose machine for carrying out the instructions of the program code. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the operations specified in the flowchart and/or block diagram block or blocks.
The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operations to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.
The flowchart and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various aspects of the inventive arrangements. In this regard, each block in the flowcharts or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified operations. In some alternative implementations, the operations noted in the blocks may occur out of the order noted in the figures. For example, two blocks shown in succession may be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustrations, and combinations of blocks in the block diagrams and/or flowchart illustrations, may be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
The corresponding structures, materials, acts, and equivalents of all means or step plus function elements that may be found in the claims below are intended to include any structure, material, or act for performing the function in combination with other claimed elements as specifically claimed.
The description of the embodiments provided herein is for purposes of illustration and is not intended to be exhaustive or limited to the form and examples disclosed. The terminology used herein was chosen to explain the principles of the inventive arrangements, the practical application or technical improvement over technologies found in the marketplace, and/or to enable others of ordinary skill in the art to understand the embodiments disclosed herein. Modifications and variations may be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described inventive arrangements. Accordingly, reference should be made to the following claims, rather than to the foregoing disclosure, as indicating the scope of such features and implementations.
