Fig. 1 is a schematic diagram of a method for controlling an electrical home device according to an embodiment of the present disclosure, and in combination with fig. 1, the embodiment of the present disclosure provides a method for controlling an electrical home device, including:

and S11, projecting an operation interface to the ground by the target household appliance, wherein the operation interface comprises a plurality of operation areas, the operation areas are respectively associated with different operation instructions, and the operation instructions are used for controlling the operation of the target household appliance.

And S12, if the target user exists in the projection area of the operation interface, determining the target operation area where the target user is located from the plurality of operation areas.

And S13, obtaining the operation instruction related to the target operation area and controlling the target household appliance.

The household appliance in the embodiment of the present disclosure may be a mobile device, an intelligent home device, or the like, or any combination thereof. In some embodiments, the smart home devices may include, for example, air conditioners, refrigerators, televisions, washing machines, and the like, or any combination thereof.

In step 11, the target household electrical appliance projects an operation interface including a plurality of operation areas to the ground, so that the user can operate the operation interface projected to the ground when the user needs to control the target household electrical appliance.

The target household appliance can be a control panel operated device, such as a washing machine, an air conditioner and the like; alternatively, the target home device may be a key-operated device, such as a refrigerator, a television, or the like.

In addition, the operation on the household appliance in the embodiment of the present disclosure may be a simple power on/off operation, and may further include other operations. Taking the target household appliance as a washing machine as an example, other operations can be embodied as: if the washing machine is provided with the projection module, an operation interface can be projected on the ground at the corresponding side of the projection module, so that a user can select the washing mode of the washing machine on the operation interface, or set the washing parameters on the operation interface, and the like. Wherein, the washing parameters comprise water temperature, running time and the like.

In step 12, it is determined whether the user is present in the projection area of the operation interface, so as to determine whether the user currently controls the target home appliance. When the user exists in the projection area of the operation interface, the target operation area where the user is located can be determined according to the position where the foot of the user is located. For example, when the target household appliance is a refrigerator, and the user exists in the projection area of the refrigerator, the operation area where the foot position of the user is located is determined as the target operation area. Therefore, the current control purpose of the user can be judged more accurately, so that the household appliance equipment can obtain an accurate control instruction.

In the embodiment of the disclosure, whether the user controls the target household appliance device can be determined by sensing whether the user exists in the projection area. For example, the presence of a user within the projected area may be sensed by infrared sensing techniques or ultrasonic reflection techniques.

In the embodiment of the present disclosure, the positions of the sensing area and the projection area may be preset according to actual conditions. The specific positions of the sensing area and the projection area can be the same or different.

In step 13, a control command associated with the target operation area can be determined and the target home device can be controlled according to the control command. The household appliance control method provides a more convenient household appliance control mode for a user, and is convenient for the user to use.

By adopting the method for controlling the household appliance provided by the embodiment of the disclosure, the problem that the household appliance cannot be controlled when a user uses an operation panel inconveniently at hand can be solved, and a more convenient household appliance control mode is provided for the user.

Optionally, in order to prevent the operation instruction from being recognized when the user passes through the projection area without the operation purpose, and thus causing the device to operate incorrectly, the embodiment of the disclosure may further determine the target operation area according to the stay time of the target user in the projection area. That is to say, when the target user is determined to be located in the projection area, the staying time of the target user in the projection area can be obtained, and when the staying time reaches the first preset time, the operation area where the target user is located is determined as the target operation area.

According to the scheme, the accuracy of identifying the operation intention of the user can be ensured, the operation event which is not intended by the user is avoided, the equipment misoperation caused by the error identification can be effectively prevented, frequent operation instruction identification is avoided, and the equipment processing resource is saved.

Optionally, determining a target operation area where the target user is located from the plurality of operation areas includes:

and S21, obtaining the environment parameter variation of a plurality of operation areas.

And S22, determining the operation area with the environment parameter variation not lower than the preset value as the target operation area.

Fig. 2 is a schematic diagram of a method for determining a target operating region according to an embodiment of the present disclosure. Referring to fig. 2, in step S21, the variation of the environmental parameters of the multiple operation areas is obtained by collecting the initial environmental parameters and the current environmental parameters of the multiple operation areas. Wherein the environmental parameters include: light brightness values and/or ultrasonic reflection values. In step S22, in the case where the amount of change in the environmental parameter reaches the preset value, the current operation region is determined to be the target operation region.

Determining that the current operating region is the target operating region includes at least the following three cases: the light brightness value variation in the current operation area exceeds a preset value, the super-radio wave reflection value variation in the current operation area exceeds a preset value, and the light brightness value variation and the super-radio wave reflection value variation in the current operation area both exceed preset values. When any one of the three situations occurs, the current operation area is determined to be the target operation area. The target operation area is determined through the environmental parameter variation, the control intention of the target user can be accurately obtained, the accuracy of the control instruction is ensured, and the accuracy of target operation area identification is improved.

Optionally, in order to save the power consumption of the device, the target household appliance may be triggered to project the operation interface to the ground when operation control is required. As an example, the target home device may project an operation interface under the trigger of the user. For example, by a human perception technology, when it is determined that there is a user with an operation intention (for example, it is sensed that there is a user around the device, and the user resides around the device for a specified time), the projection operation interface may be triggered; or, the target household appliance device is configured with a trigger key, and when the trigger key is determined to be operated by the user, an operation interface can be projected.

As another example, the target home device may perform active detection to determine whether the user interface needs to be projected.

For example, a change in the weight of the target home appliance device body may be used as a trigger condition for projecting the operation interface. Particularly, the operation interface can be projected to the ground under the condition that the weight of the main body of the target household appliance is increased, so that the use by a user is facilitated.

Taking the target home appliance as an example of a washing machine, when a target user adds laundry to the inside of the washing machine to be washed, the weight of the washing machine main body increases. That is, by detecting whether the weight of the washing machine main body is increased, it is possible to determine whether the user has a need to control the washing machine, and thus determine whether to trigger projection of the operation interface of the washing machine. In this example, when the weight of the washing machine main body increases, it may be determined that the user has a need to control the washing machine, and the operation interface may be projected onto the ground, facilitating further operation by the user.

In the actual application process, an operation interface can be projected to the ground on one side of the target household appliance main body, and a user performs operation control based on the unique projection interface; or, in order to facilitate the user operation, the operation interface can be projected on the multi-side ground of the target household appliance main body, and the user can perform operation control on any projection interface according to the use requirement of the user. Correspondingly, when the target household appliance projects the operation interface to the ground, at least one target projection surface can be determined from the plurality of projection surfaces, and the operation interface corresponding to the target projection surface can be projected to the ground.

In the technical solution provided by the embodiment of the present disclosure, when a target home appliance is configured with one projection surface and a projection condition is triggered, the target home appliance projects an operation interface to a corresponding ground. When the target household appliance has a plurality of projection surfaces, the distances between the user and the plurality of projection surfaces can be judged according to the current position of the user, and the surface with the shortest distance is used as the target projection surface. For example, when the home appliance is a washing machine, the washing machine is configured with four projection surfaces, and when a user approaches the washing machine, the distances from the user to the four projection surfaces are determined. The projection surface with the shortest distance from the user to the projection surface is used as the target projection surface, and the operation interface is projected to the target projection surface, so that the user can control the washing machine by operating the projection surface no matter at any position on the peripheral side of the washing machine, and a more convenient household appliance control mode is provided for the user.

For the scheme of projecting the operation interface on the multi-side ground, if the user displaces in the operation process, the target projection surface can be determined according to the position of the user, and operation control is not interrupted no matter the user is in any position. For example, when the user is positioned right in front of the washing machine, the front side wall of the washing machine can be determined as a target projection surface, and an operation interface is projected for the user to perform operation control; if the user moves to the right side of the washing machine after completing the starting control of the washing machine at the position, the right side wall of the washing machine can be determined as a target projection surface to project an operation interface, so that the user can complete the operation control without returning to the front side of the washing machine when performing other operation control, for example, selecting a washing mode, and the use experience of the user is improved. In addition, in order to save the power consumption of the equipment, when the operation interface is projected from the right side of the washing machine, the projection of the operation interface to the front side of the washing machine can be stopped.

Optionally, in order to determine whether the control intention of the target user is changed, it is avoided that the user controls the target device with an original operation instruction in a case where the control intention of the target user is changed. In the embodiment of the present disclosure, the position change of the target user may be determined after the second preset time period. And determining a new target operation area according to the changed position under the condition that the position of the target user is changed. And then the target household appliance is controlled according to the operation instruction associated with the new target operation area.

According to the scheme, after the target operation area is determined, a timer can be started to judge whether the second preset time length is reached. The target device can be effectively prevented from executing the original instruction operation under the condition that the control intention of the user is changed. In addition, the control instructions related to a plurality of target operation areas can be prevented from being triggered simultaneously to cause the error operation of the household appliance equipment and influence the normal use of the target household appliance equipment by setting the second preset time length.

Optionally, the target home device is configured with a distance detection module, and the method for controlling the home device provided in the embodiment of the present disclosure further includes:

and S31, obtaining the distance between the eyes of the target user and the operation interface acquired by the distance detection module.

And S32, adjusting the information displayed in the operation interface according to the distance.

Fig. 3 is a schematic diagram of another method for controlling a home appliance according to an embodiment of the present disclosure, and with reference to fig. 3, in step 31, a distance between a target user and an operation interface is collected through a distance detection module. The distance between the eyes of the target user and the operation interface can be directly detected, or the height of the target user can be detected, and the distance between the eyes of the target user and the operation interface can be obtained according to a comparison table preset by the system (the comparison table preset by the system is the comparison table of the height of the user and the distance between the eyes of the user and the operation interface).

In step 32, the display information of the operation interface is adjusted according to the distance between the eyes of the target user and the operation interface. Therefore, more personalized interface display service can be provided for the user, and the operation experience of the user is improved. The convenient requirement of the user on the control of the household appliance is met. The adjusting of the information displayed in the operation interface may be embodied as adjusting an icon and/or a text displayed on the interface, for example, adjusting a font size, an icon size, display brightness, display color, and the like, which is not limited in this disclosure.

In practical applications, in the case that the target household appliance is a washing machine and the washing machine has a plurality of projection surfaces, the position of the target user is determined. When it is sensed that the target user wants to wash the laundry and approaches the washing machine from the front, it is judged that the distance from the user to the front sidewall is shortest. And the front side wall of the washing machine is used as a target projection surface. And projecting an operation interface including a plurality of operation regions to the ground through the washing machine when the weight of the main body of the washing machine is increased. In this case, various washing modes of the washing machine, such as online washing, air washing, etc., can be displayed in different operation regions of the operation interface. And simultaneously, determining the distance between the eyes of the target user and the ground according to the height of the detected target user, and enlarging the font in the display interface under the condition that the distance between the eyes and the ground is far. And determining a target operation area where the target user is located from the plurality of operation areas. And when the target operation area is air washing, obtaining a control command related to the air washing so that the washing machine performs command operation related to the air washing according to the control command.
