Definitions

  • the present invention relates to a method and a system for controlling a hob.
  • a disadvantage is therefore that this type of voice control of the devices is difficult for the user.
  • the object of the present invention is therefore to create a solution that allows a simple control of a hob.
  • the invention is based on the finding that this object can be achieved by determining a context to which the spoken instructions intuitively used by the user usually relate.
  • the invention relates to a method for controlling a hob.
  • the method is characterized in that the method comprises the following steps:
  • the method according to the invention includes the step of detecting an object.
  • the object is preferably captured by an optical capture unit, such as a camera.
  • the entire cooktop is preferably monitored by the detection unit and a plurality of objects may also be detected as a result.
  • a cooking utensil is preferably used as the object in the method according to the invention.
  • a further step of the method according to the invention is the determination of information about the object.
  • the information about the object represents, in particular, information through which the object can be placed in a context.
  • information relating to the object itself and preferably also environmental information relating to the object are preferably determined.
  • capturing a voice instruction also includes converting the audible voice instruction into instruction data.
  • instruction data in the form of words can be generated from an acoustic spoken instruction, which can be stored digitally.
  • the recorded voice instruction is processed with at least part of the information determined.
  • the processing may include comparison and/or matching.
  • the processing can include a comparison with stored information.
  • the hob is controlled on the basis of the processing result.
  • the heating level and/or heating duration of a cooking zone is set on the basis of the processing result.
  • the step of detecting an object includes carrying out object recognition.
  • object recognition can be carried out using an algorithm which, for example, compares previously marked and stored images with the current image captured by a capture unit, for example a camera.
  • the object can be identified as cooking utensil, for example, and recognized as such.
  • determining information about the object includes detecting at least one object attribute.
  • the object whose object attributes are detected is the object detected and preferably recognized in the detection step.
  • a property or a state of the object is referred to as an object attribute.
  • Object attributes that can be detected for an object representing a piece of cooking utensil are, for example, the position, the content and/or the type of cooking utensil and/or the state of the content.
  • a pot or pan for example, can be recorded as the type of cooking utensil.
  • the position of the object on the hob is referred to as the position of the cooking utensil.
  • the position of the cookware can be a position of the cookware on a cooking zone of the hob.
  • the content of the cooking utensil represents the food to be cooked that is to be prepared in the cooking utensil.
  • the state of the content of the cooking utensil can also be recorded as an object attribute.
  • the boiling of water in a pot can be detected.
  • the object attributes can preferably be detected using an algorithm in which, for example, a currently detected image is compared with stored object attributes.
  • the user's voice instruction can be assigned to an object more precisely, and at the same time, the requirement for the technical information in the voice instruction can be reduced.
  • at least some of the object attributes, in particular the position of the cooking utensil, can also be used as information when controlling the hob.
  • the step of determining information about the object includes detecting at least one operating state of the hob.
  • the degree of heating or the heating level of the cooking zone on which the detected object is located can be detected in this step. This can be done, for example, via sensors or via wireless communication between the hob and a detection unit.
  • the step of determining the information includes combining at least two object attributes.
  • the combination of object attributes can represent the context of the object. For example, the context “pot with water” can be generated from the information “pot and “water”.
  • the step of processing the voice instruction with the ascertained information can be performed by identifying an object by comparing a stored association of the voice instruction with information about the object.
  • the context “water in pot” can be associated with both a voice instruction “egg water” and "noodle water”. If an object is currently detected whose object attributes include “water in a pot” and the user gives the voice instruction "boil pasta water", the relevant object, in particular the pot with water, can be easily identified by checking the stored assignment and the corresponding instruction regarding this pot should be carried out.
  • control of the hob represents the actuation of the cooking zone on which the identified object is located.
  • the cooking zone on which the pot with water is located can be controlled to bring the water to a boil.
  • the voice instruction represents a target statement of a cooking process.
  • the target statement can be “Please make a hard-boiled egg”. If by detecting the object and the object attributes a pot with water with an inserted egg has been recognized on a cooking zone, the cooking zone on which the pot was recognized can be controlled specifically with this target specification. In addition to a heating level, a heating duration for the cooking zone can also be set by specifying the target.
  • the method includes the step of recognizing a user.
  • the user's voice is used to recognize the user.
  • the hob is preferably controlled as a function of the user. For example, with the instruction “boil an egg”, the cooking state preferred by the user and the associated cooking time can be set automatically.
  • the user can store a user profile. The data relating to the identified user can be read from this user profile when the user is identified.
  • the method can include the step of outputting information to the user.
  • the information can in particular be a question or a confirmation request.
  • a question or confirmation request can be issued if a number of objects are detected on the hob whose object attributes do not permit unambiguous assignment to the voice instruction received. For example, if two pots of water are placed on the hob and the voice instruction "Boil pasta water" is detected, this voice instruction cannot be uniquely assigned to one of the pots.
  • the user can be asked a query in which, for example, the recorded positions of the two pots can be specified for selection.
  • the user's response can be by voice input.
  • the invention relates to a system for controlling a hob, which is characterized in that it is designed to carry out the method according to the invention.
  • the system comprises a detection unit for detecting objects, a determination unit for determining information about an object--in particular the detected object--a receiving unit for detecting a voice instruction and a processing unit for processing the recorded voice instruction with at least part of the information about the Object and a control unit for controlling the hob based on the processing results.
  • the units of the system can be at least partially integrated with each other in a common unit.
  • the units of the system can be implemented at least partially as software.
  • the detection unit for detecting objects is preferably an optical detection unit, in particular a camera.
  • the detection unit can be arranged, for example, on an extractor hood or as a self-sufficient device at a corresponding height above the hob.
  • the detection unit can also be designed to carry out object recognition.
  • the detection unit can be connected to a processing unit in which the object recognition can be carried out.
  • the determination unit for determining information about an object can be part of the detection unit or a processing unit connected thereto for object recognition. Additionally or alternatively, the determination unit can be connected to a control unit of the hob.
  • the receiving unit for detecting a spoken instruction can be provided, for example, on the hob itself, on the detection unit or on an extractor hood.
  • the processing unit for processing the recorded voice instruction with at least part of the information about the object can be integrated in the recording unit.
  • the processing unit can be provided in a separate device that is connected or networked with the detection unit, for example a mobile terminal device or a server.
  • the control unit for controlling the hob serves in particular to generate control information and/or a control signal.
  • the control unit can be integrated in the control of the hob. Alternatively, however, the control unit can also be integrated in the detection unit or a processing unit.
  • the system comprises a storage unit for storing detection results, correlations between voice instruction and object information and/or user profiles.

  • the system can use this to automatically determine the position of the pot, the setting for the hob and the cooking time.
  • Content-related or target-oriented control is thus possible through the screen information from the detection unit, which can represent a networked camera system.
  • An object on the cooktop can be analyzed and categorized by the camera system, and the system according to the invention can thus provide scope for action according to the situation.
  • the invention thus creates a possibility of making the voice input for controlling a hob or possibly also an extractor hood or other devices as simple and intuitive as possible. For this purpose, a context-related control is made possible by the invention.
  • the present invention has a number of advantages.
  • complex spoken instructions such as “set hob plate number 3 to heating level 4”, which are required in the prior art, can be avoided.
  • a simple voice instruction such as "start pasta cooking” suffices.
  • voice control for the kitchen can thus be carried out much more simply, more naturally and more intuitively than with previous solutions, in that the context is known through image processing and is included in the processing of the language.
  • the control of the hob can also be defined by formulating a target state.
  • a voice control can only process individual procedural steps.
  • Previous voice systems, such as in an oven or a coffee machine are sufficient for single command controls and processes. With multiple controls and events (operation of multiple hotplates and cookware), a clear context-related command assignment and processing is the prerequisite to ensure fast and specific control. This is possible with the present invention.
