The invention provides an information display method of an electric appliance. The electric appliance is provided with a projection device for projecting virtual images, and the electric appliance may include: at least one of an air conditioner, a refrigerator, a washing machine, and a water heater. The method comprises the following steps: determining whether virtual image projection needs to be carried out on information to be displayed; and when the virtual image projection is determined to be needed, controlling the projection device to project the virtual image to the information to be displayed aiming at the target user.
Fig. 1 is a method schematic diagram of an embodiment of an information display method of an electrical appliance provided by the present invention. As shown in fig. 1, according to an embodiment of the present invention, the information display method of the electric appliance includes at least step S110 and step S120.
Step S110, determining whether virtual image projection is required for the information to be displayed.
Specifically, determining whether to perform virtual image projection on the information to be displayed specifically may include: detecting whether a user performs a first preset operation, if so, determining that virtual image projection needs to be performed on information to be displayed; and/or detecting whether a user exists in a projection detection zone of the projection device, and if so, determining that the information to be displayed needs to be subjected to virtual image projection. Wherein the first predetermined operation comprises: a first predetermined action and/or a first predetermined voice command. The first predetermined action includes a first preset gesture, for example, a user preset gesture, and the first predetermined voice command, for example, a system set voice command, may be recognized by the voice of the user to determine whether the first predetermined voice command is the first predetermined voice command, or may be a pre-recorded voice command of the user.
Step S120, when it is determined that the information to be displayed needs to be subjected to virtual image projection, controlling the projection device to perform virtual image projection on the information to be displayed for the target user.
Fig. 2 is a flowchart illustrating a step of controlling the projection device to project a virtual image of information to be displayed for a target user according to an embodiment of the present invention. As shown in fig. 2, step S120 may specifically include step S121 and step S122.
And step S121, determining the projection position of the virtual display screen when the virtual image projection is carried out according to the position and the height of the target user.
The target user is a user detected in a projection detection interval of the projection device; and when the virtual image projection is determined to be needed, taking the first user detected in the projection detection zone of the projection device as a target user, or taking the user performing the first preset operation as the target user. For example, when it is detected that a user performs a first predetermined operation for starting a virtual projection function, the user within a projection detection zone of the projection apparatus is detected, and a first user detected within the projection detection zone is taken as a target user, or when it is detected that the user performs the first predetermined operation, the user performing the first predetermined operation is taken as a target user. The projection device can project the projection to the user in the projection detection zone of the projection device. The projection position of the virtual display screen comprises: the height of the center of the virtual display screen from the ground and the position of the virtual display screen in the effective projection interval of the projection device. The effective projection interval of the projection device is an interval which can be projected when the projection device projects the virtual image.
FIG. 3 is a flowchart illustrating steps of determining a projection position of a virtual display screen during virtual image projection according to a position and a height of a target user according to an embodiment of the present invention. As shown in fig. 3, step S121 may specifically include step S1211 and step S1212.
And S1211, determining the height from the center of the virtual display screen to the ground according to the height of the target user.
Specifically, in order to present a better virtual projection effect to the target user, the height of the eyes of the target user and the height of the center of the virtual display screen can be kept horizontal when the virtual image is displayed, so that the height of the eyes of the target user can be determined according to the height of the target user, and the height of the center of the virtual display screen from the ground can be determined according to the height of the eyes of the target user. For example, if the height of the user is detected to be 1.72m, the height of the eyes of the user can be calculated and analyzed to be about 1.6 m.
Step S1212, determining the position of the virtual display screen in the effective projection area according to the position of the target user and a preset distance.
The preset distance may be specifically a preset distance between the virtual display screen and the target user, or a distance between the virtual display screen and the target user determined according to a preset virtual display screen size, for example, a preset virtual display screen size when performing virtual projection according to a user, and a corresponding relationship between the preset virtual display screen size and the distance, to determine a distance between the corresponding virtual display screen and the target user. When the virtual image is projected, the virtual image is projected in an effective projection interval of the projection device, the position of the target user may specifically be the position of the target user in the effective projection interval, and the position of the virtual display screen in the effective projection interval when the virtual image is projected, that is, the position in front of the eyes of the target user and at a preset distance from the user, may be determined according to the position of the target user in the effective projection interval and the distance between the virtual display screen and the target user.
And step S122, controlling the projection device to project a virtual image to the information to be displayed according to the determined projection position of the virtual display screen.
And projecting the virtual display screen with the corresponding size at the corresponding height of the corresponding position of the effective projection interval according to the determined position of the virtual display screen in the effective projection interval, the height of the center of the virtual display screen from the ground and the preset size of the virtual display screen so as to perform virtual image projection on the information to be displayed. For example, in fig. 7, the virtual display screen 4 or 5 is located 0.5m (this value is only an example and can be set according to specific situations) in front of the position of the target user in the effective projection zone, and the height of the center of the display screen is the same as the eye height of the target user.
The information to be displayed includes: key information of the electrical appliance and/or operation information of the electrical appliance; the virtual display screen includes: a key area and/or a display area; the key area is used for displaying key information of the electrical appliance; the display area is used for displaying the operation information of the electric appliance. For example, as shown in fig. 4a, the virtual display screen, taking an air conditioner as an example, includes a key region 1 and a display region 2, where the key region 1 is operable by a user, and for example, the user may perform operations such as turning on and off the air conditioner, adjusting the wind speed, and adjusting the wind sweeping manner (up-down wind sweeping or left-right wind sweeping) in the key region of the virtual display screen. The display area displays current operation information of the air conditioner, such as current temperature, humidity and the like, and the function information refers to functions of the air conditioner, such as voice, image, PM2.5 removal and the like.
The information to be displayed further includes: at least one item of indoor and outdoor environment information, weather information, music playing information and video information; fig. 4b, fig. 4c, and fig. 4d may be referred to for virtual image projection of the information to be displayed, where fig. 4b illustrates an example of a virtual display screen when virtual image projection is performed on weather information according to an embodiment of the present invention; fig. 4c shows an example of a virtual display screen when virtual image projection is performed on music playing information according to an embodiment of the present invention; fig. 4d shows an example of a virtual display screen when performing virtual image projection on video information according to an embodiment of the present invention. When the information to be displayed comprises at least one of indoor and outdoor environment information, weather information, music playing information and video information, controlling the projection device to project virtual images of the information to be displayed for a target user, and matching corresponding virtual display screen display modes according to the type of the information to be displayed so as to project the virtual images of the information to be displayed. The user can control the display of the information to be displayed through the virtual display screen, for example, when the information to be displayed includes video information, the video information is displayed by matching to a corresponding virtual display screen display mode, and the user can perform operations such as picture amplification, definition switching, fast forward, backward, pause and the like on the virtual display screen.

Specifically, a section in which the distance from the installation position of the projection device in a room (in the length, width and height ranges) where the projection device is located is less than or equal to a first predetermined distance and is within an effective projection angle range is determined as an effective projection section of the projection device, wherein the first predetermined distance is the farthest distance that the projection device can project. For example, as shown in fig. 7, in a room where the projection device 3 is located, an angle is within an effective projection angle range of the projection device 3 (i.e., an arbitrary angle position of the interval a1 to a10 shown in fig. 6) with the position of the projection device 3 as the center, and a radius is within 10m as an effective projection interval.
The projection detection zone of the projection device refers to an effective detection judgment range of the projection device, and the projection device can project the projection to the user in the projection detection zone of the projection device. The projection detection interval may be a preset detection interval, and the virtual image projection of the information to be displayed is performed only for the target user detected in the projection detection interval, where the projection detection interval specifically includes a projection detection distance and a projection detection angle range, and the projection detection distance and/or the projection detection angle range is a preset detection distance and/or angle range for detection, and/or a detection distance and/or angle range that can be detected by a device for detecting a user in the projection detection interval, where the projection detection distance and/or the projection detection angle range may be preset according to a maximum distance and/or an effective projection angle range that can be projected by the projection device, for example, the projection detection distance is less than or equal to the maximum distance (first predetermined distance) that can be projected by the projection device, and/or the projection detection angle range is less than or equal to the effective projection angle range. Specifically, a section in which the distance from the installation position of the projection device in the room (in the length, width and height ranges) in which the projection device is located is equal to or less than a second predetermined distance and is within the projection detection angle range is determined as the projection detection section of the projection device, wherein a section in which the distance from the installation position of the projection device in the room in which the projection device is located is equal to or less than the second predetermined distance (projection detection distance) and is outside the projection detection angle range is determined as the projection detection blind area of the projection device. For example, as shown in fig. 7, the projection detection interval is: A. b, C, wherein: a is a small visual angle area, B is a conventional visual angle area, C is a super visual angle area), the A, C interval can detect, but certain error exists in accuracy, and shadow is a projection detection blind area.

Specifically, the determining unit 110 determines whether virtual image projection is required to be performed on the information to be displayed, including: detecting whether a user performs a first preset operation, if so, determining that virtual image projection needs to be performed on information to be displayed; and/or detecting whether a user exists in a projection detection zone of the projection device, and if so, determining that the information to be displayed needs to be subjected to virtual image projection. Wherein the first predetermined operation comprises: a first predetermined action and/or a first predetermined voice command. The first predetermined operation includes a preset gesture, for example, a gesture preset by a user, and the first predetermined voice command, for example, a voice command set by a system, may be recognized by the voice of the user to determine whether the first predetermined voice command is the first predetermined voice command, or may be a voice command pre-recorded by the user.
The target user is specifically a user detected in the projection detection zone of the projection device. When the determining unit 110 determines that the virtual image projection of the information to be displayed is required, the control unit 120 takes the first user detected in the projection detection zone of the projection device as a target user, or takes the user performing the first predetermined operation as a target user. For example, when it is detected that a user performs a first predetermined operation for starting a virtual projection function, the user within a projection detection zone of the projection apparatus is detected, and a first user detected within the projection detection zone is taken as a target user, or when it is detected that the user performs the first predetermined operation, the user performing the first predetermined operation is taken as a target user. The projection device can project the projection to the user in the projection detection zone of the projection device. And when the virtual image is projected, the virtual image is projected in an effective projection interval of the projection device. The effective projection interval of the projection device is an interval which can be projected when the projection device projects the virtual image.
Optionally, the control unit 120 is further configured to stop performing virtual image projection on the information to be displayed when a second predetermined operation performed by the target user is received. Wherein the second predetermined operation comprises: a second predetermined action and/or a second predetermined voice command. The second predetermined action includes a second preset gesture, for example, a user preset gesture, and the second predetermined voice command, for example, a system set voice command, may be recognized by the voice of the user to determine whether the second predetermined voice command is the second predetermined voice command, or may be a pre-recorded voice command of the user.
Fig. 10 is a block diagram of an embodiment of a control unit according to an embodiment of the present invention, and as shown in fig. 10, in an embodiment, the control unit 120 includes a projection position determining unit 121 and a virtual image projection unit 122.

Specifically, in order to present a better virtual projection effect to the target user, the height of the eyes of the target user and the height of the center of the virtual display screen may be kept horizontal when the virtual image is displayed, and therefore, the first determining subunit may determine the height of the eyes of the target user according to the height of the target user, so as to determine the height of the center of the virtual display screen from the ground according to the height of the eyes of the target user. For example, if the height of the user is detected to be 1.72m, the height of the eyes of the user can be calculated and analyzed to be about 1.6 m.
The preset distance may be specifically a preset distance between the virtual display screen and the target user, or a distance between the virtual display screen and the target user determined according to a preset virtual display screen size, for example, a distance between the corresponding virtual display screen and the target user is determined according to a preset virtual display screen size when the user performs virtual projection, and a corresponding relationship between the preset virtual display screen size and the distance. The second determining subunit may determine, according to the position of the target user in the effective projection interval and the distance between the virtual display screen and the target user, the position of the virtual display screen in the effective projection interval when performing virtual image projection, that is, the position in front of the eyes of the target user and the distance between the virtual display screen and the target user, where the distance between the virtual display screen and the user is a preset distance.
Correspondingly, the virtual image projection unit 122 projects the virtual display screen with the corresponding size at the corresponding height of the corresponding position of the effective projection interval according to the determined position of the virtual display screen in the effective projection interval, the height of the center of the virtual display screen from the ground and the preset size of the virtual display screen, so as to perform virtual image projection on the information to be displayed. For example, in fig. 7, the virtual display screen 4 or 5 is at a position 0.5m ahead of the position of the target user within the effective projection zone and the height of the center of the display screen is the same as the eye height of the target user, respectively.
The information to be displayed includes: key information of the electrical appliance and/or operation information of the electrical appliance; the virtual display screen includes: a key area and/or a display area; the key area is used for displaying key information of the electrical appliance; the display area is used for displaying the operation information of the electric appliance.

Specifically, a section in which the distance from the installation position of the projection device in a room (in the length, width and height ranges) where the projection device is located is less than or equal to a first predetermined distance and is within an effective projection angle range is determined as an effective projection section of the projection device, wherein the first predetermined distance is the farthest distance that the projection device can project. For example, as shown in fig. 7, in a room where the projection device 3 is located, an angle is within an effective projection angle range of the projection device 3 (i.e., an arbitrary angle position of the interval a1 to a10 shown in fig. 6) with the position of the projection device 3 as the center, and a radius is within 10m as an effective projection interval.
The projection detection zone of the projection device refers to an effective detection judgment range of the projection device, and the projection device can project the projection to the user in the projection detection zone of the projection device.
