Based upon the detected input being unrecognized, the appliance may create a new user profile associated with the detected input and modify operation of a burner according to the detected input.

Description:
TECHNICAL FIELD 
     The present specification generally relates to smart appliances that facilitate user interaction through audio and/or motion input and, more specifically, to smart appliances that are customizable to specific users through repeated interaction, including users that utilize client devices to interact with smart appliances, and media and methods of use for such appliances. 
     BACKGROUND 
     Users have traditionally utilized buttons and knobs to control appliances such as stoves. These appliances have not provided for hands-free operation, such as through voice or motion/gesture control. If a user&#39;s hand was covered in sauce, for example, the user may have had the choice of either getting sauce on knobs, or else risk burning what is on the stove while taking time to clean their hands. Further, these appliances have not been customizable to specific users. 
     Accordingly, a need exists for an appliance that provides customizable hands-free operation for specific users, and media and methods of use of such appliances. 
     SUMMARY 
     A method for hands-free use of an appliance, comprising detecting input from a hands-free user, the detected input being voice or gesticular. The method further compares the detected input to known inputs and retrieves the user&#39;s profile based on the detected input corresponding to a known input. The method also, based upon retrieval of the user&#39;s profile, outputs recognition of the user input and modifies operation of a burner according to both the user input and the retrieved user profile. Further still, the method, based upon the detected input being unrecognized, creates a new user profile associated with the detected input and modifying operation of a burner according to the detected input. 
     In another embodiment, an appliance provides hands-free operation. The appliance comprises a burner, memory, a processor coupled to the memory, and a detection unit. The detection unit is configured to detect input from a hands-free user, with the detected input being voice or gesticular. The detection unit is further configured to retrieve the user&#39;s profile based on the detected input corresponding to a known input. The detection unit, based upon retrieval of the user&#39;s profile, is also configured to output recognition of the user input and modifies operation of a burner according to both the user input and the retrieved user profile. The detection unit, based upon the detected input being unrecognized, is also configured to create a new user profile associated with the detected input and modify operation of a burner according to the detected input. 
     In yet another embodiment, a non-transitory computer readable medium embodies computer-executable instructions, that when executed by a processor, cause the processor to detect input from a hands-free user, the detected input being voice or gesticular. The medium also, when executed by a processor, compares the detected input to known inputs and retrieves the user&#39;s profile based on the detected input corresponding to a known input. Based upon retrieval of the user&#39;s profile, the medium also, when executed by a processor, outputs recognition of the user input and modifies operation of a burner according to both the user input and the retrieved user profile. Based upon the detected input being unrecognized, the medium further still, when executed by a processor, creates a new user profile associated with the detected input and modifies operation of a burner according to the detected input. 
     These and additional features provided by the embodiments described herein will be more fully understood in view of the following detailed description, in conjunction with the drawings.

     Turning now to  FIG. 2 , a flowchart  200  for user authentication and hands-free appliance control is depicted, through which embodiments of the disclosure can be implemented. At  202 , the appliance detects and/or receives input from a user. The input may be any suitable type of audio or motion detected from a user. Examples of user-produced audio include spoken word(s), singing, humming, whistling, grunting, groaning, shrieking, gargling, or any other suitable type of detectable sound produced by a user. Motion produced by a user may be any type of detectable movement, and may include any type of movement a user&#39;s limbs/digits (or partial limbs/digits, such as due to amputations or other health issues), head, torso, or any portion of the user&#39;s body capable of exhibiting detectable movement. Some embodiments also utilize motion detection for objects under direct control of the user, such as hand-held objects. Other embodiments may include motion detection of objects not directly in contact with the user, such as objects being thrown or juggled. In some embodiments, the appliance may provide feedback indicating a response to received input. Some embodiments provide for visual biometric authentication, such as through a retinal scan, a fingerprint scan, etc. Appliance feedback may include any suitable type of output through, for example, output devices/displays  104 , which may be visual (such as a screen, etc.), audio (via a speaker, etc.) that may include spoken output, or any other suitable type of output. The appliance  100  may provide output/feedback to a user in various embodiments described herein. 
     At  202 , the appliance receives and/or detects input from the user. In various embodiments, detection component  120  provides audio and/or motion detection. Detection component  120  may utilize input detected by input device  106 , such as a microphone or motion-sensor, and analyze the input utilize processor  102 . User input, as discussed above, may be either audio or motion detected from the user. In this example, a user provides a spoken phrase and/or an arm gesture. 
     At  204 , the appliance attempts to authenticate the user. In this example, the user speaks a command or password. A user may be identified through voice analysis performed by the detection component  120 . The user may also be identified based on a specific word or phrase, which may or may not involve authenticating based on the voice itself. Other embodiments utilize input in the form of motion and/or gestures. For example, a user may wave an arm or extend a hand, which may become uniquely associated with the user. In another embodiment, the appliance includes a visual detection device  120  such as a camera (motion, still, infrared, etc.) to visually authenticate the user. Any type of visual authentication may be utilized, such as iris scanning, finger-print scanning, etc. The appliance stores users profiles in memory ( 108 ,  110 ,  116 , etc.), remotely, such as in a network  114  (cloud-based storage, etc.) and/or on a remote device  118 . In some embodiments, if the user was previously authenticated at the start of the current session (e.g., a series of interactions with a user within a time period that may or may not have a time limit, such as a session timeout), the user authentication at  204  may be skipped. 
     At  206 , if a user cannot be authenticated (e.g., there is not profile associated with the user), in some embodiments the appliance denies access to the user, thereby returning to  202 . This may be, for example, because the owner of the appliance is away and does not want anyone (such as a child) playing with the appliance and possibly creating harm. Some embodiments may allow basic functionality such as turning on a burner in a restricted-functionality mode and/or restrict other features such as using a timer. In some embodiments, certain profiles may have restricted access, such as a child&#39;s profile. If a user cannot be authenticated, the appliance may create an anonymized (i.e., an anonymous user) profile. In some embodiments, an anonymized profile may store any suitable data about the user, include usage statistics. If the appliance allows unauthenticated users to operate the appliance, then the appliance may perform requested functions at  210 . Some embodiments also distinguish between multiple users, such as only accepting input from one user while ignoring inputs from other users (e.g., if there is a group of people gathered near the appliance  100 ). 
     Returning to  204 , if the user is authenticated, then at  208  in this example the appliance checks to see whether the user input is directed towards updating the user&#39;s profile. Examples of user input to update their profile includes, for example, updating contact information and/or a listing of other people that the user has indicated are permitted to utilize the appliance. Other examples of updated profile information may include new authentication information (new phrase, new motion, etc.) or new commands (new voice commands, new motion commands, etc.). In some embodiments, an authenticated user may grant access to other users (authenticated or unauthenticated) indefinitely or for a fixed time duration. Other embodiments may grant such access for a session, which may last until the user affirmatively ends the session through input, or after a period of time (which may be customizable in some embodiments). If the input in this embodiment is directed towards updating the user profile, then the appliance updates the user profile at  212 . Once the profile is updated, the appliance checks for more input at  214 . 
     If the user input is not directed towards updating the user profile, the appliance proceeds to  210  to perform the requested function. In some embodiments, a function that cannot be performed (such as requesting an appliance such as a stove to freeze food) may result in feedback indicating that the function cannot be performed. Some user requests may result in confirmation from the appliance, such as the duration and temperature at which to cook food. Some input may then require further input, such as a request to cook food resulting in the appliance requesting more information such as the type of food, the food&#39;s current temperature, the food&#39;s weight, the food&#39;s desired cooking temperature, the duration of the cooking, etc. In some embodiments, as discussed above, the detection component  120  may weigh objects (such as food placed upon a stove) where the input device senses weight (such as with a scale). Food weight may be utilized to calculate various meal options for a user. Once the requested function is performed, the appliance checks for more input at  214 . If more input is received/detected from the user, the appliance receives the input at  202 . 
       FIG. 3A  is a depiction  300 A of gesture-based selection of a burner  308 A of appliance  304 A, through which embodiments of the disclosure can be implemented. In this embodiment, a user may utilize a hand-gesture  302 A to select a burner  308 A, where the number of extended fingers corresponds to the desired burner (three fingers for burner number three for example). Any number of burners or any type of burner may be utilized herein for any example, including a mixture of different burner types for a single appliance. Continuing with this embodiment, selection of the burner may result in output from the appliance  304 A indicating the burner  308 A has been activated. Examples of such output may include indicator lights, verbal feedback, or a tone/music. Other burners  306 A,  310 A and  312 A may be activated as well. Any type of gesture, movement, or audio input may be utilized to interact with burners in the embodiments depicted in  FIGS. 3A-3C . 
       FIG. 3B  is a depiction  300 B of gesture-based activation of a burner  308 B of appliance  304 B, through which embodiments of the disclosure can be implemented. In this embodiment, a hand rotating gesture  302 B turns on a burner  308 B, where the burner was previously selected in  FIG. 3A . Other embodiments may provide for immediate activation without first selecting a burner. Some embodiments may allow a generic gesture, such as no fingers needed (a general hand rotation) once the burner has already been selected (such as with three fingers). 
       FIG. 3C  is a depiction  300 C of gesture-based user heating of a burner  308 C of appliance  304 C, through which embodiments of the disclosure can be implemented. In this embodiment, a hand-raising gesture  302 C raises the temperature of a burner  308 C. Other embodiments may provide for a temperature increase without first selecting a burner, as three fingers in a hand-raising motion may immediately identify the burner as part of the gesture. Some embodiments may allow a generic gesture, such as no fingers needed (a general hand-raise) once the burner has already been selected (such as with three fingers). In some embodiments, the appliance  304 C may provide visual feedback. For example, a display may show the desired/target temperature, which increases as the hand is raised higher and decreases as the hand is lowered. Some embodiments may provide spoken feedback in place of, or combined with, visual feedback. 
     Safety features, such as an immediate shut-off of a burner  308 C, may be accomplished by built-in safety features via the safety component  122 . The safety component  122  may provide, for example, automatic shutoff of one or all burners if a user waves both hands or utters a phrase such as ‘help,’ ‘stop,’ ‘fire,’ etc. The safety component  122  may also utilize, for example, an infrared camera  106  as a safety feature (either on the appliance  304 C or located externally, such as on a remote device  118  as discussed in more detail below). The infrared camera may be utilized to detect smoke particles above a hot burner  308 C and turn the burner off and/or alert the user. 
     Turning now to  FIG. 4 , a diagram of a user with an augmented-reality device with a view of an appliance is shown, through which embodiments of the disclosure can be implemented. In this embodiment, a user  402  is depicted wearing augmented-reality glasses  404 , although any other type of augmented reality device may be used. The location and orientation of the user may taken into account so that the augmented content may be adapted if the user  402  moves around with the glasses  404 . Within the field of vision  406  of the glasses  404 , the user  402  sees an appliance  408  with a hot burner  410 . Continuing with this embodiment, a virtual arm  412  is depicted in the glasses  404  that appears transparent, although the arm may appear solid or have any suitable type of appearance. The virtual arm  412  may correspond to the user&#39;s arm  412  movements, either fully or partially. Other embodiments may display the arm  412  in a manner that does not correspond to the user&#39;s movement in any way. The glasses  404  may have a data connection with the appliance  408 , alerting the glasses to the fact that the burner  410  is hot. Other embodiments may have the glasses  404  detecting the heat from the burner  410  without any type of data connection, instead rely upon direct detection (visual, thermal, infrared, etc.). In this embodiment, the virtual arm  412  touches or overlays upon the real burner  410  that is hot, and provides a warning notification  414  stating “Danger!” in the glasses  404  to the user  402 . Any type of notification may be utilized, including visual, audio, tactile (such as a vibration in the glasses), etc. For example, the virtual arm may virtually touch each burner, yet only provide a notification if a hot burner is touched. Other embodiments may provide simulated conditions related to the appliance, such as hot burners or fires, where no such conditions actually exist. Other embodiments provide that the glasses  404  update the augmented reality conditions based upon user input (audio command, gesture, etc.), data received from other sources (e.g., from over a network, etc.), or any other suitable source. 
     Some embodiments utilize other types of wearable electronics, such as fitness trackers, which are often worn on the wrist. A fitness tracker may be connected to the appliance  408 , which may result in real-time or periodic data communications. Some embodiments provide for the appliance  408  to send an alert to the user when certain conditions are met, such as when a burner is hot or above a certain temperature. In this example, the notification may be defined by the appliance  408  and/or the user  402 . In such embodiments, data relating to the user (such as calories burned within a period of time) can be utilized by the appliance  408  for personalized communications, such as food portion size, if the burner  410  has a scale to weigh food. Continuing with this scenario, the appliance  408  and/or the glasses  404  (if available) may communicate with the user  402 , such as with a personalized message  414  in the glasses  404 , based upon the fitness tracker data. In various embodiments, operation of the appliance  408  may be modified by the appliance&#39;s observation of the user  402 . Some embodiments modify operation of the appliance  408  based upon monitoring data from a fitness tracker and data detected by the appliance  408 . 
     In some embodiments, wearable devices may be utilized to detect a user&#39;s motion. For example, a device worn on the user&#39;s wrist may used to detect movements that can then be used to control the appliance  408 . In other examples, a device worn on one or more of a user&#39;s fingers may be used to detect movement/gestures made with a user&#39;s arm, hand, and/or finger(s). In examples where a user utilizes a wearable device, detected user motion can be transmitted to the appliance  408 , either directly or to any number of intermediate devices (servers, other appliances, etc.). In such examples, the appliance  408  need not have and/or utilize its own detection component  120 , as the wearable device may serve as a detection component. Other examples may have the appliance  408  utilizing input from one or more wearable devices even where the appliance  408  has a detection component  120 . In such examples, the appliance  408  may use motion detection from its own detection component  120 , one or more wearable devices, or any combination thereof. 
     Some embodiments utilize neural networks (i.e., machine learning), which may be distributed over one or more networks  114  and/or with one or more remote devices  118 . For example, data relating to cooking food on a burner  410  can be gathered from any number of users and, based upon the aggregated data, provide useful data to the appliance  408  and/or user  402 , which can be utilized for improved energy efficiency, improved cooking experiences, etc. Updating of appliance  408  operations based on a neural network may be an iterative process, where the appliance  408  sends updated data to the network and receives further data to further modify its operations. Some embodiments provide for more complete control over the appliance  408  from the glasses  404 , such as power options, profile management, setting rules/restrictions, timers, etc. For example, a rule could be set to restrict authenticated users that are less than ten years of age with respect to cooking duration, temperature, or number of burners usable at one time. 
       FIG. 5  depicts a diagram  500  of a user  510  utilizing augmented-reality on a handheld device to simulate conditions with an appliance  502 , through which embodiments of the disclosure can be implemented. In this embodiment, the appliance  502  has an unheated burner  504  underneath an unheated pan  506  which contains uncooked food  508 . The user  510  holds a smartphone  512 , which displays onscreen  514  an augmented reality version of the appliance  516 . On the screen  514  the burner  504  is depicted as a simulated hot burner  518 , along with a simulated hot pan  520  and cooking food  522  accompanied by simulated heat  524  arising. The smartphone  512  may have a data connection with the appliance  502 , and in some embodiments the smartphone  512  can update the augmented reality display to adapt to changing conditions of the appliance  502 . Other embodiments may provide that the smartphone  512  updates the augmented reality conditions based upon user input (audio command, gesture, etc.), data received from other sources (e.g., from over a network, etc.), or any other suitable source. Some embodiments provide for more complete control over the appliance  502  from the smartphone  512 , such as power options, profile management, setting rules/restrictions, timers, etc. Some embodiments provide for recommendations provided to the user  510  from the appliance  502 , smartphone  512 , augmented reality glasses  404 , etc., relating to data specific the user  510  and/or their profile, equipment they are utilizing (glasses  404 , fitness tracker, etc.), and/or appliance  502 . Some embodiments utilize food profiles, which contain motion gestures and/or spoken words identified with the food item, information relating to specific foods, such as allergens, calories, cooking times, indicating combinations with other foods for recipes, all of which may be utilized as data by the user&#39;s smartphone  512 , glasses  404 , and/or appliance  502 . 
     In some embodiments, a user  510  may input any number of criteria to further enhance the augmented reality experience. The user may provide such input on the appliance  502 , or on a separate device  512 , which may be handheld, head-mounted  404 , or be any other type of device (laptop, desktop, etc.). The user-specified data may be utilized to overlay other types of data, in addition to the exemplary overlain data described above (such as  412 ,  522 , and  524 ). Such user-specified overlay data may be output directly as an overlay, or may be utilized in other ways. For example, a user  510  may desire to cook an item, such as sautéed onions. The user  510  may select from among a variety of cooking options (such as sautéed, fried, etc.), where each cooking option may provide a cooking time, and which may also incorporate additional user input such as the weight, type, and/or quantity of onions being sautéed. In another example, the user  510  may provide data, such as a specific amount of time that the onions should be cooked, which may be input by the user (spoken, gestured, and/or provided by finger-based input) to reach a desired outcome (such as sautéed onions). The user&#39;s device  512  may provide notification (visual, audio, vibration, etc.) to the user  510  that an event has occurred, is occurring, or will occur (cooking time reached, time to flip, etc.). In this example, the user  510  and/or the user&#39;s device  512  may turn away from the onions currently cooking. In some examples a notification may occur when, after having left the display  514 , the sautéing onions then return to view on the display  514  (such as when the user&#39;s device pans back around). The notification may display, for example, when the sautéed onions are ready, the amount of cooking time remaining only when the onions appear on the display  514 , when the onions are actually in view (such as via a camera associated with the user&#39;s device), etc. Some examples may allow the user  510  to modify their input (such as cooking type, ingredients), or the input of another user, at any time or during intervals (defined by a user, automatically defined, associated with the food type, etc.). 
     In multiple embodiments, data regarding food preparation may be communicated between an appliance  502  and remote devices  118  such as augmented reality glasses  404 , smartphones  512 , and refrigerators (not shown). For example, a smart refrigerator that keeps track of what types of food are in the refrigerator and/or how long each item has been in the refrigerator may communicate various recipes to the appliance  502  based upon the contents that are in the refrigerator and/or what types of food the user  510  may buy (whether such data is input by the user  510  or inferred from data usage pattern derived from the user&#39;s history and/or the histories of multiple users over a neural network). The appliance  502  may, based on data from a refrigerator, alert the user  510  that the last of a food type is being used and more should be purchased, and/or which food in the refrigerator is currently edible.
