Description

Title of the invention: METHOD FOR CONTROLLING A HOUSEHOLD APPLIANCE Field of invention

[0001] The present invention relates to the field of household appliances, and more particularly to domestic household appliances.

[0002] The invention relates more particularly to a method for controlling such a household appliance by means of a human-machine interface adapted to control said household appliance in response to a gesture made by at least one hand of a user. State of the prior art

[0003] Domestic household appliances, such as cooking plates, domestic cooking ovens, washing machines or even dishwashers, etc. generally have a main casing housing components allowing the household appliance to perform its function, and a human-machine interface which can be arranged in a plane parallel to the front face of the household appliance, that is to say in a plane parallel to the front face of the casing.

[0004] This human-machine interface can, in a known manner, be controlled with or without contact from a user. In other words, a user can control a human-machine interface by pressing buttons provided for this purpose such as buttons defined on a touch screen, or can perform a gesture remotely which will be detected by the human-machine interface.

[0005] For example, document CH700524 describes a domestic appliance comprising a contactless input unit configured to distinguish different trajectories of a user's hand and to generate different signals depending on the trajectories.

[0006] Document EP2806334 is also known, which describes a method of operating a user interface controlled on the basis of a gesture.

[0007] Thus, with such solutions, a user can control his domestic household appliance without having to touch this domestic household appliance.

[0008] However, a disadvantage of such solutions is that the contactless input unit may be required to detect trajectories of a user's hand which would correspond to noise coming for example from a person passing nearby and making a movement without actually wanting to control the device. household appliances, or a child making gestures in front of the contactless entry unit.

[0009] Furthermore, it may prove complex for some users to control such a domestic household appliance because comparing a trajectory carried out by a user's hand with a trajectory generating a signal may prove difficult to carry out if the trajectory carried out includes complex movements.

[0010] Furthermore, it may prove useful to limit certain control functions depending on the user who will control the device, for reasons of authorization or even security.

[0011] There is therefore a need to provide a solution for optimizing the control of such domestic household appliances, and in particular for simplifying the remote, or contactless, control of such domestic household appliances, by limiting unwanted or unauthorized uses. Statement of the invention

[0012] The invention aims to remedy at least in part the drawbacks mentioned above relating to the techniques of the prior art.

[0013] To do this, the invention relates to a method for controlling a household appliance by means of a human-machine interface adapted to control said household appliance in response to a gesture made by at least one hand of a user, said human-machine interface comprising: - an acquisition module configured to detect a gesture performed by said at least one hand, said gesture being composed of at least one movement performed in at least a given time, and configured to compare said detected gesture with a plurality of predetermined sequences, each of said predetermined sequences corresponding to a respective control instruction of said household appliance, each of said predetermined sequences comprising at least one predetermined movement to be performed in a predetermined period of time; - a control module configured to deliver said respective control instruction to said household appliance if said detected gesture is performed in a predefined detection zone and if said detected gesture corresponds to one of said predetermined sequences.

[0014] According to the invention, said plurality of predetermined sequences comprises a first group of predetermined sequences and a second group of predetermined sequences. Furthermore, said human-machine interface is adjustable between at least three detection levels: - a first detection level in which said control module is deactivated, said human-machine interface not delivering a control instruction for said household appliance; - a second detection level in which said control module is activated, said human-machine interface being capable of delivering a control instruction for said household appliance if said detected gesture corresponds to one of said predetermined sequences of said first group of predetermined sequences, and - a third detection level in which said control module is activated, said human-machine interface being capable of delivering a control instruction for said household appliance if said detected gesture corresponds to one of said predetermined sequences of said first group of predetermined sequences and / or of said second group of predetermined sequences.

[0015] Thus, the solution proposes a new approach and invention making it possible to resolve at least in part some of the drawbacks of the prior art.

[0016] In particular, such a solution makes it possible to simplify the remote, or contactless, control of such domestic household appliances, by limiting unwanted or unauthorized uses.

[0017] For example, the proposed solution allows only certain users to access the gestures of the second group, when the household appliance is at the first or second level.

[0018] Implementing these levels also adds a level of security because if one wishes to disable the detection of particular gestures or gestures for a given time, one can set the human-machine interface to the first level. This avoids the risks of detecting trajectories of a user's hand that would correspond to noise coming, for example, from a person passing nearby and making a movement without wanting to control the domestic appliance, or a child making gestures in front of the contactless input unit. For example, for a hob, a parent can set the human-machine interface to the first level so that if a child passes nearby and makes a gesture that could have been interpreted as a control gesture, no control instruction is issued.

[0019] According to a particular aspect of at least one embodiment of the invention, said predefined detection zone has a pyramidal shape extending between a top carried by said human-machine interface and a base located at a normal distance to the top of between 30 and 70 cm, preferably 50 cm, the base extending over a length of between 20 cm and 40 cm, preferably 30 cm, the base extending over a width of between 20cm and 40cm, preferably 30cm, the base being centered on the normal to the man-machine interface.

[0020] According to a particular aspect of at least one embodiment of the invention, said acquisition module is configured to transmit to said control module said predetermined sequences detectable as a function of said adjustment of the detection level of said human-machine interface.

[0021] According to a particular aspect of at least one embodiment of the invention, in said second detection level and third detection level, the control module is activated following the detection of a gesture corresponding to a predefined adjustment request sequence, said gesture being performed by said at least one hand in said predefined detection zone.

[0022] According to a particular aspect of at least one embodiment of the invention, said predetermined adjustment request sequence comprises: - a first part of detected gesture in which the movement consists of an approach towards said human-machine interface from a normal distance to said human-machine interface greater than 200mm to a normal distance to said human-machine interface of between 8mm and 200mm, then - a second part of detected gesture in which the movement consists of a separation of said human-machine interface up to a normal distance to said maximum human-machine interface less than 200mm in a time between 50ms and 750ms, then - a third part of detected gesture in which said movement consists of an approach towards said human-machine interface up to a normal distance to said minimum human-machine interface greater than 8mm in a time between 50ms and 750ms, then - a fourth part of detected gesture in which the movement consists of a separation of said human-machine interface from a distance normal to said human-machine interface from a distance between 8mm and 200mm to a distance normal to said human-machine interface greater than 200mm.

[0023] According to a particular aspect of at least one embodiment of the invention, the first group of predetermined sequences comprises predetermined sequences in which the at least one predetermined movement is exclusively rectilinear and comprises a separation of said human-machine interface by a distance normal to said human-machine interface of between 150mm and 350mm and / or a bringing together of said human-machine interface by a distance normal to said human-machine interface between 150mm and 350mm and / or a rectilinear movement in a plane parallel to said human-machine interface.

[0024] According to a particular aspect of at least one embodiment of the invention, said first group of predetermined sequences comprises: an emergency function of the household appliance; a power level setting; a time setting; a setting of a parameter; a choice of program; a command interface operation; a selection of an item of household appliance.

[0025] According to a particular aspect of at least one embodiment of the invention, the second group of predetermined sequences comprises predetermined sequences in which the at least one predetermined movement is at least partially rotary relative to an axis normal to said human-machine interface at a distance normal to said human-machine interface of between 150mm and 300mm.

[0026] As a result, the second group of predetermined sequences may include more complex predetermined sequences with combinations of rotation and rectilinear movements, which allows for a greater number of commands of the household appliance.

[0027] According to a particular aspect of at least one embodiment of the invention, said second group of predetermined sequences comprises said first group of predetermined sequences and further comprises: a parameter change to be adjusted; a timer setting. a choice of program for using the household appliance.

[0028] The invention also relates to a human-machine interface intended to implement a method for controlling a household appliance according to one of the aforementioned embodiments, adapted to control said household appliance in response to a gesture made by at least one hand of a user, said human-machine interface comprising:

[0037] [Fig-1] is a schematic view of a human-machine interface according to a mode of realization of the invention;

[0040] [Fig.4] is a schematic representation of a gesture to be detected to deliver a control instruction corresponding to a parameter setting.

[0041] Detailed description of an embodiment of the invention

[0042] Identical elements shown in the above-mentioned figures are identified by identical numerical references.

[0043] The invention relates to a method 100 for controlling a household appliance 9.

[0044] This household appliance, or domestic household appliance, may in particular belong to the group comprising: - a cooking table; - an oven; - a washing machine; - a dishwasher; - a hood.

[0045] The method 100 for controlling a household appliance is therefore carried out by means of a human-machine interface 90 adapted to control this household appliance 9 in response to a gesture made by at least one hand of a user.

[0046] This control of the household appliance is done without contact between the user and the human-machine interface 90.

[0047] In other words, this control of the household appliance is done remotely, that is to say with a non-zero distance between the hand of a user and the human-machine interface 90.

[0048] It should be noted that according to alternative embodiments, the household appliance can however retain part of the controls that can be activated by contact between the user and control means provided on the human-machine interface.

[0049] Such a human-machine interface 90 may comprise, as illustrated in [Fig.l], an acquisition module 900, a control module 901, and a storage module 902.

[0050] The acquisition module 900 is configured to detect a gesture performed by at least one hand, to compare this detected gesture with a plurality of predetermined sequences.

[0051] According to the proposed solution, each of the predetermined sequences corresponds to a respective control instruction of the household appliance 9. Each of these predetermined sequences comprises at least one predetermined movement to be carried out within a predetermined period of time.

[0052] The acquisition module comprises, in the illustrated embodiment, a time-of-flight sensor 9000 and a microprocessor 9001.

[0053] The time of flight (or ToF in English for Time of Flight) sensor can for example comprise a time of flight camera, a Radar system, i.e. by wave detection, or a Lidar system, i.e. by laser detection.

[0054] The storage module 902 is configured to store the different predetermined sequences which will be compared with the gesture detected by the acquisition module.

[0055] As for the control module 901, it is here configured to deliver the control instruction for the household appliance.

[0056] This respective control instruction of the household appliance 9 is delivered if the detected gesture is carried out in a predefined detection zone 8 and if the detected gesture corresponds to one of the predetermined sequences.

[0057] In the embodiment presented, and as visible in [Fig.2], the predefined detection zone 8 here has a pyramidal shape extending between a top 80 carried by the human-machine interface 90 and a base 81 located at a normal distance to the top 80 of between 30 and 70 cm, preferably 50 cm, the base 81 extending over a length of between 20 cm and 40 cm, preferably 30cm, the base 81 extending over a width of between 20cm and 40cm, preferably 30cm, the base 81 being centered on the normal N to the man-machine interface 90.

[0058] In other embodiments, a predefined detection zone could be provided having another shape, such as a cylindrical shape, a rectangular shape.

[0059] A multiple detection zone could also be provided, with a human-machine interface presenting several time-of-flight sensors.

[0060] It should be noted that the gesture performed by the at least one hand has a spatial component which can be two-dimensional or three-dimensional, namely the movement, and a spatial component, namely the given time.

[0061] As illustrated in [Fig.l], the human-machine interface 90 further comprises a display and / or input device 92 for a user, so as to be able to communicate with the user.

[0062] This human-machine interface 90 is adapted to control the household appliance by means of a method 100 for controlling a household appliance 9 in response to a gesture made by at least one hand of a user.

[0063] As illustrated in [Fig.3], in this control method, the plurality of predetermined sequences comprises a first group G1 of predetermined sequences and a second group G2 of predetermined sequences.

[0064] More particularly, in this embodiment, the first group G1 of predetermined sequences comprises predetermined sequences in which the at least one predetermined movement is exclusively rectilinear and comprises a separation of the human-machine interface 90 by a distance normal to the human-machine interface 90 of between 150mm and 350mm and / or a movement closer to the human-machine interface 90 by a distance normal to the human-machine interface 90 of between 150mm and 350mm and / or a rectilinear movement in a plane parallel to the human-machine interface 90.

[0065] In other words, this first group G1 comprises predetermined sequences in which the movement(s) are simple, and comprise one or more rectilinear movements.

[0066] This first group G1 of predetermined sequences comprises here: - an emergency function of the household appliance; - a power level setting; - a time setting; - a setting of a parameter; - a choice of program;

[0067]

[0068]

[0069]

[0070]

[0071]

[0072]

[0073]

[0074]

[0075] - a command interface operation; - a selection of an element of the household appliance. As for the second group G2 of predetermined sequences, it comprises predetermined sequences in which the at least one predetermined movement is at least partially rotary relative to an axis normal to the human-machine interface 90 at a distance normal to the human-machine interface 90 of between 150mm and 300mm. In other words, this second group G2 includes predetermined sequences in which the movement(s) are more complex, and include one or more curved movements. This second group G2 could thus correspond to a group of predetermined sequences for an experienced user, or to a group of sequences linked to less frequent functionalities, while the first group G1 could correspond to a group of predetermined sequences for a beginner user, or to a group of sequences linked to frequently used functionalities of the household appliance. This second group G2 of predetermined sequences here comprises the first group G1 of predetermined sequences, and further comprises: - a parameter change to be adjusted; - a timer setting. - a choice of program for using the household appliance. The examples of predetermined sequences belonging to the first group G1 or to the second group G2 are only non-limiting examples of predetermined sequences for these two groups. For example, one could also plan predetermined sequences involving two hands of a user. A third group could also be provided comprising these predetermined sequences involving two hands of a user. Another group could also be provided to allow a user to learn the gestures for controlling a household appliance. According to the invention, the human-machine interface is adjustable between at least three detection levels: - a first detection level NI in which the control module 901 is deactivated, the human-machine interface 90 not delivering any control instruction for the household appliance 9; - a second detection level N2 in which the control module 901 is activated, the human-machine interface 90 being able to deliver a control instruction for the household appliance 9 if the detected gesture corresponds to one of the predetermined sequences of the first group G1 of predetermined sequences, and - a third detection level N3 in which the control module 901 is activated, the human-machine interface 90 being able to deliver a control instruction for the household appliance 9 if the detected gesture corresponds to one of the predetermined sequences of the first group G1 of predetermined sequences and / or of the second group G2 of predetermined sequences.

[0076] According to the illustrated embodiment, in the second detection level N2 and the third detection level N3, the control module 901 is activated following the detection of a gesture corresponding to a predefined adjustment request sequence, the gesture being performed by at least one hand in the predefined detection zone 8.

[0077] Detecting such a gesture in order to activate the control module makes it possible to add additional security, for example to prevent children from using the household appliance.

[0078] We now present, in relation to [Fig.4], an embodiment of a gesture to be detected to deliver a control instruction corresponding to an adjustment request according to an embodiment of the invention.

[0079] As schematically illustrated in this [Fig.4], the control instruction corresponds to an adjustment request if the detected gesture comprises four parts presented as follows: - a first part PI of detected gesture in which the movement consists of an approach towards the human-machine interface 90 from a normal distance to the human-machine interface 90 greater than 200mm to a normal distance to the human-machine interface 90 between 8mm and 200mm, then - a second part P2 of detected gesture in which the movement consists of a separation of the human-machine interface 90 up to a normal distance to the human-machine interface 90 maximum less than 200mm in a time between 50ms and 750ms, then - a third part P3 of detected gesture in which the movement consists of an approach towards the human-machine interface 90 up to a normal distance to the human-machine interface 90 minimum greater than 8mm in a time between 50ms and 750ms, then - a fourth part P4 of detected gesture in which the movement consists of a separation of the human-machine interface 90 by a distance normal to the human-machine interface 90 from a distance between 8mm and 200mm up to a normal distance to the human-machine interface 90 greater than 200mm.

[0080] In other words, the control instruction corresponds to an adjustment request if the gesture comprises moving closer to a predetermined distance from the human-machine interface, then moving away from the human-machine interface by a predetermined distance within a predetermined period of time, then moving closer to the human-machine interface by a predetermined distance within a predetermined period of time, to end with moving away to a predetermined distance from the human-machine interface.

[0081] It should be noted that, in this embodiment, the acquisition module 900 is configured to detect and transmit to the control module 901 the predetermined sequences detectable as a function of said setting of the detection level of the human-machine interface 90.

[0082] Therefore, if the human-machine interface is set to the first detection level NI, the acquisition module 900 does not detect and does not transmit a detectable predetermined sequence to the control module 901.

[0083] It could however be provided that the first level of adjustment of the human-machine interface includes at least the detection of an emergency gesture so as to issue an emergency extinguishing control instruction.

[0084] If the human-machine interface is set to the second detection level N2, the acquisition module 900 detects and transmits predetermined sequences detectable to the control module corresponding to the first group G1 of predetermined sequences, with therefore predetermined sequences in which the movement(s) are simple, and comprise one or more rectilinear movements.

[0085] If the human-machine interface is set to the third detection level N3, the acquisition module 900 detects and transmits predetermined sequences detectable to the control module corresponding to the first group G1 of predetermined sequences and to the second group G2 of predetermined sequences, therefore with both predetermined sequences in which the movement(s) are simple and comprise one or more rectilinear movements, and predetermined sequences in which the movement(s) are more complex and comprise one or more curved movements.

[0086] Such operation of the human-machine interface allows the acquisition module 900 to filter the gesture detection and thus eliminate unwanted gestures that are not expected at the defined detection level, but also to accept gestures with greater tolerance in the defined low detection levels and tighten the tolerance in the higher detection levels to better discriminate the gestures. The higher the detection level, the greater the number of gestures and the more complex the gestures are to execute. By adjusting the detection level based on the user's dexterity, the system ensures that the command desired by the user is delivered.

[0087] One method for filtering gesture detection is the use of a tolerance margin on the gesture detection. Thus, depending on the detection level of the human-machine interface, a tolerance margin is provided on the precision of the gesture to be performed by a user's hand, with, for example, for each predetermined sequence, a predefined deviation from the theoretical trajectory of the gesture (for example a rectilinear trajectory or a circular trajectory), a predefined margin for the distance to the human-machine interface or the distance in space from the theoretical trajectory and a predefined margin for the predetermined time period. For example, a tolerance margin of between 10 and 25% could be provided if the human-machine interface is set to the second detection level N2, and a tolerance margin of between 0 and 10% if the human-machine interface is set to the third detection level N3.We would thus have a human-machine interface in which the higher the detection level, the greater the number of gestures and the more precise the gestures must be to be able to be properly detected.
