DETAILED DESCRIPTION
The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar elements. While embodiments of the invention may be described, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the elements illustrated in the drawings, and the methods described herein may be modified by substituting, reordering, or adding stages to the disclosed methods. Accordingly, the following detailed description does not limit the invention. Instead, the proper scope of the invention is defined by the appended claims.
Spoken dialog systems (SDS) enable people to interact with computers with their voice. The primary component that drives the SDS may comprise a dialog manager: this component manages the dialog-based conversation with the user. The dialog manager may determine the intention of the user through a combination of multiple sources of input, such as speech recognition and natural language understanding component outputs, context from the prior dialog turns, user context, and/or results returned from a knowledge base (e.g., search engine). After determining the intention, the dialog manager may take an action, such as displaying the final results to the user and/or continuing in a dialog with the user to satisfy their intent.
FIG. 1 is a block diagram of an operating environment 100 comprising a user 105, a server 107, a network 120, and a user device 130. Server 107 may comprise a spoken dialog system (SDS 110, a personal assistant program 112, and/or a search agent 118). SDS 110 may be operative to receive user phrases, queries, actions, and/or action requests via a network 120. Network 120 may comprise a private network (e.g., a corporate intranet), a cellular network, and/or a public network such as the Internet. Operating environment 100 may further comprise a plurality of data sources 150(A)-(C). User device 130 may be operative to provide a displayed image 132 such as that associated with photos, videos, and/or games. User device 130 may be coupled to a camera 135 that may be operative to record user 105 and capture motions and/or gestures made by user 105. User device 130 may be further operative to capture words spoken by user 105, such as by a microphone 136, and/or capture other inputs from user 105 such as by a keyboard and/or mouse (not pictured). Consistent with embodiments of the invention, camera 135 may comprise any motion detection device capable of detecting the movement of user 105. For example, camera 135 may comprise a Microsoft® Kinect® motion capture device comprising a plurality of cameras and a plurality of microphones.
FIG. 2 is a flow chart setting forth the general stages involved in a method 200 consistent with an embodiment of the invention for providing personalization of a user query. Method 200 may be implemented using a computing device 300 as described in more detail below with respect to FIG. 3. Ways to implement the stages of method 200 will be described in greater detail below. Method 200 may begin at starting block 205 and proceed to stage 210 where computing device 300 may receive a plurality of signals from a user. For example, SDS 110 may receive a spoken query and identify a first gesture performed by user 105 by camera 135. For example, user may wave and say a command like ‘hey xbox’.
Method 200 may then advance to stage 220 where computing device 300 may determine whether the signals are directed to the system. For example, user 105 pointing to the screen may comprise an activation gesture while user 105 walking past camera 135 may not. Consistent with embodiments of the invention, user 105 may define any gesture as an associated gesture. If the identified gesture and/or the speech signal is identified as not being directed to SDS 110, method 200 may end at stage 275.
If the signals are directed to the system, method 200 may advance to stage 230 where computing device 300 may retrieve a context associated with a visual display. For example, metadata may be associated with a video stream providing information such as the title, actors, description, ratings, etc. For another example, the context may be retrieved from one of data sources 150(A)-(C). For example, data source 150(A) may comprise a movie information website.
Method 200 may then advance to stage 240 where computing device 300 may translate the received signals into an agent action. For example, camera 135 may capture a pointing gesture of user 105 that may be operative to indicate a subset of the visual display. For example, there may be three actors in a current frame of a movie video, and the camera may identify which of the three actors user 105 is pointing to. This indication may be used to create an agent action in association with a speech query such as “Who is that actor?”. The agent action may thus be able to selectively identify which of the three actors the user is indicating.
Method 200 may then advance to stage 250 where computing device 300 may perform the agent action according to the retrieved context and the received signals. For example, SDS 110 may retrieve a list of all actors in the displayed movie from data source 150(A), narrow the results to the three actors displayed at the time the signals were received, and identify the specific actor according to which one user 105 was pointing at.
Method 200 may then advance to stage 260 where computing device 300 may display a result associated with the performed query to the user. For example, a caption may be displayed on user device 130 providing the result of the query. Method 200 may then end at stage 275.
An embodiment consistent with the invention may comprise a system for providing a user-interaction activation. The system may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to receive a query from a user, retrieve a context associated with a visual display, perform the query according to the retrieved context, and display a result associated with the performed query to the user. The visual display may comprise, for example, a still image, a video, and/or a game image. Being operative to perform the query according to the retrieved context may comprise the processing unit being operative to narrow down a plurality of results to a subset of the plurality of results according to the retrieved context. The processing unit may be further operative to receive a gesture from the user, update the retrieved context according to the gesture (e.g., a pointing gesture), and perform the query according to the updated context. Being operative to update the retrieved context according to the pointing gesture may comprise the processing unit being operative to identify an element of the visual display indicated by the pointing gesture.
Another embodiment consistent with the invention may comprise a system for providing a user-interaction activation. The system may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to receive a request comprising a natural language phrase (e.g., a spoken phrase), retrieve a context associated with a visual display, identify a gesture performed by the user, perform an action associated with the request according to the retrieved context and the identified gesture, and provide a result associated with the performed action to the user. Consistent with embodiments of the invention, a natural language phrase may comprise spoken and/or conversational grammar rather than a specially formatted query. For example “what is that building” may comprise a natural language phrase and may be associated with a visual display of the movie “Inception.” A comparable formatted query such as may be provided to a search engine may comprise “domain:imdb.com title: Inception time: 1:32 ‘identify building’ coordinates: 132,425.” The visual display may comprise an image captured by a recording device associated with the user. For example, the user may take a digital picture with a camera and view the image. The user's gesture may comprise an activation gesture. For example, user 105 may point directly at camera 135 to indicate that user 105 is about to issue a query and/or action.
Yet another embodiment consistent with the invention may comprise a system for providing a user-interaction activation. The system may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to receive a plurality of contemporaneous signals from a user, wherein at least one first signal comprises a speech signal received via at least one microphone and at least one second signal comprises a gesture received via the at least one camera, and determine whether the first gesture comprises an activation gesture plurality of signals are associated with directed to the system. In response to determining that the plurality of signals are directed to the system, the processing unit may be operative to receive a query from the user, retrieve a context associated with a visual display, identify a second gesture received from the user via the camera, translate the plurality of signals into at least one agent action associated with the visual display, wherein the gesture comprises a pointing gesture operative to select a subset of the visual display, perform the query agent action according to the retrieved context and the identified second gesture and display a result associated with the performed query agent action to the user.
