Description
Technical Field
The present invention relates to a method and a system for controlling a stove.
Background
In modern kitchens it is currently known to control devices by means of speech recognition. In this case, the required voice commands have to be very technical and detailed in order to generate the corresponding control signals from these voice commands.
Thus, there is a disadvantage in that it is difficult for the user to perform this type of voice control on the device.
Disclosure of Invention
The task of the present invention is therefore to create a solution that allows a simple control of the stove.
The invention is based on the following knowledge: this task may be solved by determining the context in which the voice instructions that are intuitively used by the user are typically related.
According to a first aspect, the invention relates to a method for controlling a stove. The method is characterized in that the method comprises the following steps:
the object to be detected is a sample of the object,
information about the object is determined and,
the voice command is detected and the voice command is detected,
processing the detected voice instruction using at least a portion of the determined information, an
The stove is controlled based on the result of the processing.
Controlling the stove refers in particular to setting a heating level or a heating duration of one or more cooking zones of the stove. Controlling the stove may also be referred to as steering.
The method according to the invention comprises the step of detecting the object. The object is preferably detected by an optical detection unit, e.g. a camera. Preferably, the entire stove is monitored by the detection unit in this step, and thus a plurality of objects are also detected if necessary. Preferably, a cooker is used as an object in the method according to the invention.
A further step of the method according to the invention is to determine information about the object. Information about the object may be used in particular for introducing the object into the context. For this purpose, information about the object itself is preferably determined and environmental information about the object is preferably also determined.
Detecting a voice command refers in particular to receiving an acoustic voice command at an acoustic receiving unit. Preferably, detecting the voice command further comprises converting the acoustic voice command into command data. For example, instruction data in the form of words that may be digitally stored may be generated from acoustic voice instructions.
In a further step of the method according to the invention, the detected voice command is processed using at least a part of the determined information. The processing may include comparison and/or assignment. In particular, the processing may include comparing with stored information.
The stove is controlled based on the result of the processing. For example, a heating level and/or a heating duration of the cooking zone is set based on the processing result.
According to the present invention, by taking into account information about objects in addition to a user's voice command when controlling a stove, a context-dependent control can be created. In particular, the voice control can thus be performed more simply, more naturally and intuitively.
According to a preferred embodiment, the step of detecting the object comprises performing object recognition. In particular, at least one object may be identified from the detected image by object identification. Object recognition may be performed by means of an algorithm which compares, for example, a previously marked and stored image with a current image detected by a detection unit, e.g. a camera. Upon object identification, an object may be identified, for example, as a cooker and identified as a cooker.
According to one embodiment, determining information about the object includes detecting at least one object attribute. The object of the detected object attribute is the object detected and preferably identified in the detecting step. In particular, a property or state of an object is referred to as an object property.
By taking into account at least one object attribute in addition to the voice command when controlling the stove, the voice command of the user can be more simply assigned to a specific object.
Object properties that may be detected for an object representing a cookware are, for example, the position, content and/or type of the cookware and/or the status of the content. As a type of cooker, for example, a saucepan or pan may be detected. The position of the cookware refers in particular to the position of the object on the stove. In particular, the position of the cookware may be the position of the cookware on the cooking area of the stove. The contents of the cooker represent the cooked food that should be prepared in the cooker. Additionally or alternatively, the state of the content of the cookware may also be detected as an object property. In this case, for example, the boiling of water in the boiler can be detected.
The object properties may preferably be detected by means of an algorithm in which, for example, a currently detected image is compared with stored object properties.
By detecting the object properties, the user's voice commands can be assigned to the object more accurately, and here the requirements for technical specifications in the voice commands can be reduced at the same time. In addition, at least part of the object properties, in particular the position of the cookware, can also be used as information when controlling the stove.
According to another aspect, the step of determining information about the object comprises detecting at least one operating state of the stove. In particular, the degree of heating or the level of heating of the cooking zone in which the object to be detected is located can be detected in this step. This may be done, for example, by a sensor or by wireless communication between the stove and the detection unit.
According to a preferred embodiment, the step of determining the information comprises combining at least two object properties. The combination of object properties may represent the context of the object. For example, the context "a boiler with water" may be generated from the information "boiler" and "water".
According to one embodiment, the step of processing the voice command with the determined information may comprise identifying the object by comparing with a stored allocation of voice commands to information about the object.
For example, the context "water in a boiler" may be assigned to both the voice command "egg water" and "noodle water". If the object properties of the object currently detected include "water in a boiler" and the user issues a voice command "water for cooking noodles", the object concerned, in particular a boiler with water, can be identified in a simple manner by checking the stored allocation and a corresponding command relating to the boiler can be executed.
According to one embodiment, controlling the stove represents manipulating a cooking zone in which the identified object is located. In the above example, the cooking zone in which the boiler with water is located may be manipulated to boil the water.
According to one embodiment, the voice command represents a target specification of the cooking process. For example, the target specification may be "please cook eggs". If a cooking pot with an egg placed in water on the cooking zone is identified by detecting the object and the object properties, the cooking zone on which the cooking pot is identified can be specifically controlled in the case of the target specification. In addition, the heating duration of the cooking zone may be set by the target specification in addition to the heating level.
According to one embodiment, the method includes the step of identifying the user. Preferably, the user's speech is used to identify the user. Preferably, the control of the stove is performed according to a user. So that, for example, in the case of the instruction "cook eggs" the cooking state preferred by the user and the cooking duration associated therewith can be automatically set. To this end, the user may store a user profile. When a user is identified, data relating to the identified user may be read from the user profile.
According to one embodiment, the method may include the step of outputting information to a user. The information may in particular be a question or an acknowledgement request. In particular, if a plurality of objects are detected on the stove, and the object properties of these objects are not allowed to be explicitly assigned to the received voice command, a question or confirmation request may be output. For example, if two cookers with water are placed on a stove and a voice command "noodle boiling water" is detected, the voice command cannot be explicitly assigned to one of the cookers. In this case, a question can be asked to the user, in which for example the detected positions of the two cookers can be indicated for selection. The user's response may be through voice input.
According to another aspect, the invention relates to a system for controlling a cooking range, said system being characterized in that the system is designed to perform the method according to the invention.
The advantages and features already described and to be described in relation to the method according to the invention, if applicable, are correspondingly applicable to the system according to the invention and vice versa.
According to one embodiment, the system comprises a detection unit for detecting an object, a determination unit for determining information about the object (in particular the detected object), a receiving unit for detecting a voice command, a processing unit for processing the detected voice command with at least a part of the information about the object, and a control unit for controlling the stove based on the processing result.
The units of the system may be at least partially integrated with each other in a common unit. The units of the system may be designed at least partly as software.
The detection unit for detecting the object is preferably an optical detection unit, in particular a camera. The detection unit may be arranged, for example, on a range hood or as a self-sufficient device at a corresponding height above the range. The detection unit may be designed to also perform object recognition. Alternatively, the detection unit may be connected to a processing unit in which object recognition may be performed.
The determination unit for determining the information about the object may be part of the detection unit or part of a processing unit connected to the detection unit for object recognition. Additionally or alternatively, the determination unit may be connected with a control unit of the stove.
The receiving unit for detecting the voice command may be provided, for example, on the stove itself, on the detecting unit or on the range hood.
The processing unit for processing the detected speech instructions with at least a part of the information about the object may be integrated in the detection unit. Alternatively, the processing unit may be provided in a separate device, such as a mobile terminal or server, but connected or networked to the detection unit.
The control unit for controlling the hob is in particular for generating control information and/or control signals. The control unit may be integrated in a controller of the stove. Alternatively, however, the control unit may also be integrated in the detection unit or the processing unit.
According to one embodiment, the system comprises a storage unit for storing the detection result, the correlation between the voice instruction and the object information and/or the user profile.
If the units of the system are not arranged in a common unit, these units are designed to communicate with each other, in particular to communicate wirelessly.
Drawings
The invention is described in more detail below with reference to the drawings.
FIG. 1 shows a schematic block diagram of an embodiment of a system according to the present invention; and
fig. 2 shows a flow chart of an embodiment of the method according to the invention.
Detailed Description
As shown in fig. 1, the system 1 comprises a detection unit 10, a receiving unit 11, a processing unit 12, a determining unit 13, and a control unit 14. In the embodiment of fig. 1, the system 1 further comprises a storage unit 15.
In the embodiment shown in fig. 1, the system 1 is arranged on the range hood 2 or integrated into the range hood 2. In the embodiment shown, the detection unit 10 is arranged on the underside of the range hood 2. The detection unit 10 preferably comprises a camera.
A stove 3 is arranged below the smoke exhaust ventilator 2. The detection area of the detection unit is directed in the direction of the stove 3 and is schematically shown by a dashed line in fig. 1. In this case, the size of the area of the detection area in the plane of the stove 3 corresponds to the area of the stove 3. Thus, in the embodiment shown, the detection area of the detection unit 10 covers the stove 3.
If cooking is performed on the stove 3, the detection unit 10 preferably detects the entire cooking process. Here, for example, a video of the entire cooking process is recorded. In this case, in particular, an object in the detection region of the detection unit 10 is detected.
For example, if a boiler is placed on the stove 3, the boiler is located within the detection area of the detection unit 10.
The boiler may be identified as an object by object identification in the detection unit 10 or in an identification unit, not shown. In addition, object properties regarding the boiler may be determined in the determination unit 13. For this purpose, the image detected by the detection unit 10 may be transferred to the determination unit 13. For example, it may be determined in the determination unit 13 what is inside the boiler. The detection unit 10 and the determination unit 13 may be connected to a storage unit 15.
The voice command of the user of the stove 3 can be received by the receiving unit 11. The speech instructions may be processed, in particular converted, in the receiving unit 11 or the processing unit 12. In the processing unit 12, the determined object properties may be utilized for processing the speech instructions. Based on the processing result, control instructions are generated in the control unit 14 and transmitted to the stove 3.
In fig. 2, an embodiment of the method according to the invention is schematically shown as a flow chart.
By means of a camera, preferably arranged in the detection unit 10, the situation occurring on the stove 3 is constantly analyzed and the cookers (pans, saucepans, etc.) and, if necessary, the positions of these cookers are identified. In addition, it is also possible to identify as much as possible what is being prepared in the boiler or pan. These properties are preferably stored consecutively. The system 1 may also query the settings of the stove 3 if the stove 3 has a data exchange/interface. The stored properties and settings of the stove 3 represent the context for speech input, in particular speech instructions. The system knows not only where the boiler is located, but also the context in which the boiler is located. Based on this context, the user may use the simplified voice command.
The combination "position = upper right", "content = pasta + water", "type = saucepan" gives "noodle water" as a simplified context-based phonetic name for the saucepan. For language communication, the user may now use the term "noodle water" instead of the term "upper right boiler". Based on the voice command "noodle water", the cooking zone (in this example: right front) where the saucepan is located can be manipulated so that the heating level of the saucepan is increased.
The invention is not limited to the embodiments shown.
In another scenario, the user issues, for example, an instruction "boil water in a boiler". Based on the context, the system knows where the boiler is located and can operate the stove accordingly. Furthermore, it is now also possible to monitor the boiler and optionally there is the possibility of closing immediately upon boiling of the water.
For example, if the system identifies multiple cookers, the system may request a more detailed description from the user by asking back.
In addition, context-sensitive speech input according to the present invention can also be arbitrarily extended. For example, the user may also put an egg into water and say: please cook eggs. The system can thus automatically determine the position of the boiler, the setting of the stove and the cooking time.
Furthermore, the user profile may be assigned by means of speech recognition, for example with a preferred recipe or cooking level. The following commands can then also be executed: "do my breakfast eggs as usual".
Thus, content-dependent or object-oriented control may be achieved by display screen information provided by a detection unit, which may be a networked camera system. By means of which objects on a stove can be analyzed and classified, and thus an operating space can be provided by the system according to the invention corresponding to a situation.
The invention thus creates the possibility of making the voice input for controlling the stove or, if necessary, the range hood or other device as simple and intuitive as possible. For this purpose, context-dependent control is achieved by the invention.
The present invention has a number of advantages. In particular, the complex voice instructions required in the prior art, such as "set furnace plate No. 3 to heating level 4", can be avoided. In the present invention where the voice command is processed in consideration of the context, a simple voice command such as "start cooking pasta" is sufficient.
The invention can thus be used to control speech for a kitchen more simply, naturally and intuitively than in the solutions hitherto, by knowing the context through image processing and introducing the context into the speech processing. Control of the stove may also be defined herein by tailoring the target state. Without context, speech control can only handle individual method steps.
Heretofore speech systems, such as in ovens or coffee machines, have been adequate for single command control and flow. In the case of multiple control elements and events (running multiple stoves and cookware), explicit context-dependent command distribution and handling is a precondition to ensure rapid and specific control. This can be achieved with the present invention.
