In connection with the description of the drawings, similar reference numerals may be used for similar components.

[0039] In describing the present disclosure, if it is determined that a specific description of a related known function or configuration may unnecessarily obscure the gist of the present disclosure, a detailed description thereof will be omitted.

[0040] Additionally, the following embodiments may be modified in various other forms, and the scope of the technical concepts of the present disclosure is not limited to the following embodiments. Rather, these embodiments are provided to further faithfully and completely convey the technical concepts of the present disclosure to those skilled in the art.

[0041] The terminology used in this disclosure is for the purpose of describing specific embodiments only and is not intended to limit the scope of the rights. Singular expressions include plural expressions unless the context clearly dictates otherwise.

[0042] In this disclosure, expressions such as “has,” “can have,” “includes,” or “may include” indicate the presence of a corresponding feature (e.g., a component such as a number, function, operation, or part), and do not exclude the presence of additional features.

[0043] In this disclosure, expressions such as “A or B,” “at least one of A and / or B,” or “one or more of A or / and B” can include all possible combinations of the listed items. For example, “A or B,” “at least one of A and B,” or “at least one of A or B” can all refer to (1) including at least one A, (2) including at least one B, or (3) including both at least one A and at least one B.

At this time, the external device may communicate with the electronic device (100) and the server through multiple communication interfaces.

[0096] And, the external device on which the remote control application is installed may be a smartphone, but this is only one example, and the application may be implemented through various devices on which the application can be installed, such as an AI speaker.

[0097] In addition, the electronic device (100) can be connected to an external device via a communication interface (110) or an input / output interface (125) via wires / wireless, and the electronic device (100) can receive an audio signal for a user's voice from the external device.

[0098] According to one or more embodiments of the present disclosure, the electronic device (100) can acquire a user voice to switch the operating state of the electronic device (100) or the input state of the electronic device (100) through a microphone (135) or an external device.

[0099] The projection unit (140) is a configuration that projects an image externally. According to various embodiments of the present disclosure, the projection unit (140) may be implemented using various projection methods (e.g., CRT (cathode-ray tube) method, LCD (Liquid Crystal Display) method, DLP (Digital Light Processing) method, laser method, etc.).

[0100] Meanwhile, the projection unit (140) may include various types of light sources. For example, the projection unit (140) may include at least one light source among a lamp, an LED, and a laser.

[0101] The projection unit (140) can output images in a 4:3 screen ratio, a 5:4 screen ratio, or a 16:9 wide screen ratio depending on the purpose of the projector (100) or the user's settings, and can output images in various resolutions such as WVGA (854*480), SVGA (800*600), XGA (1024*768), WXGA (1280*720), WXGA (1280*800), SXGA (1280*1024), UXGA (1600*1200), Full HD (1920*1080), UHD (3840*2160), etc. depending on the screen ratio.

[0102] The projection unit (140) can perform various functions for adjusting the output image under the control of the processor (160). For example, the projection unit (140) can perform functions such as zoom, keystone, quick corner (4 corner) keystone, and lens shift.

[0103] Specifically, the projection unit (140) can perform a zoom function to enlarge or reduce an image depending on the distance from the screen (projection distance).

[0104] The method of performing a zoom function can be divided into a hardware method that adjusts the screen size by moving the lens and a software method that adjusts the screen size by cropping the image. When the zoom function is performed, the focus of the image needs to be adjusted. Focus adjustment can be performed using a manual focus method or an electric focus method. The manual focus method refers to a method of focusing manually. The electric focus method refers to a method of automatically focusing using a motor. The projector (100) can selectively provide a digital zoom function or an optical zoom function.

[0105] The projection unit (140) can also perform a keystone correction function. If the height is not right for frontal projection, the screen may be distorted upwards or downwards. The keystone correction function refers to the function of correcting a distorted screen. For example, if distortion occurs in the left and right directions of the screen, it can be corrected using horizontal keystone, and if distortion occurs in the up and down directions, it can be corrected using vertical keystone. The quick corner (4 corner) keystone correction function is a function that corrects the screen when the center area of ​​the screen is normal but the corner areas are not balanced. The lens shift function is a function that moves the screen as it is when the screen is off the screen.

[0106] The projection unit (140) can automatically analyze the surrounding environment and projection environment and provide zoom / keystone / focus functions even without user operation. Specifically, the projection unit (140) can automatically provide zoom / keystone / focus functions based on the distance between the projector (100) and the screen (e.g., a wall or floor) detected by the sensor (155), information about the space where the projector (100) is currently located, information about the amount of ambient light, etc.

[0107] Additionally, the projection unit (140) can provide a lighting function using a light source. In particular, the projection unit (140) can output light using a light source such as one or more LEDs.

[0108] The projection unit (140) may output a light source using a surface-emitting LED, depending on the implementation example. The surface-emitting LED is an LED having a structure in which an optical sheet is placed on the upper side of the LED so that light is evenly distributed and output.

[0109] The projection unit (140) may also provide the user with a dimming function for adjusting the intensity of the light source. Specifically, when the user inputs a command for adjusting the intensity of the light source through various operation interfaces such as a touch screen, button, dial, etc., the projection unit (140) may control the LED to output light with an intensity corresponding to the user command. Alternatively, the projection unit (140) may provide a dimming function based on content analyzed by the processor (160) without user input. Specifically, the projection unit (140) may control the LED to output the intensity of the light source based on information about the currently provided content (e.g., content type, content brightness, etc.).

[0110] The projection unit (140) can also control the color temperature under the control of the processor (160).

[0111] The laser (145) is configured to project light externally. The camera (150) is configured to capture images. Since the laser (145) and the camera (150) have been described with reference to FIG. 1, a duplicate description will be omitted.

[0112] The sensor (155) is configured to detect changes in the inclination of the electronic device. The sensor (155) can detect changes in the pitch angle, roll angle, or yaw angle of the electronic device (100). The sensor (155) may be implemented as a tilt detection sensor, a motion sensor, an acceleration sensor, or a gyro sensor, but is not limited thereto.

[0113] The processor (160) can control the overall operation and function of the electronic device (100). Specifically, the processor (160) is connected to the configuration of the electronic device (100) including the memory (105), and can control the overall operation of the electronic device (100) by executing at least one command stored in the memory (105) as described above.

[0114] The processor (160) may be implemented in various ways. For example, the processor (160) may be implemented as at least one of an application specific integrated circuit (ASIC), a logic integrated circuit, an embedded processor, a microcomputer (Micom), a microprocessor, hardware control logic, a hardware finite state machine (FSM), and a digital signal processor (160).

[0115] In particular, the processor (160) may include one or more processors. Specifically, the one or more processors may include one or more of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), an Accelerated Processing Unit (APU), a Many Integrated Core (MIC), a Digital Signal Processor (DSP), a Neural Processing Unit (NPU), a Main Processing Unit (MPU), a hardware accelerator, or a machine learning accelerator. The one or more processors may control one or any combination of other components of the electronic device, and may perform operations related to communication or data processing. The one or more processors may execute one or more programs or instructions stored in a memory. For example, the one or more processors may perform a method according to an embodiment of the present disclosure by executing one or more instructions stored in a memory.

[0116] When a method according to one or more embodiments of the present disclosure includes multiple operations, the multiple operations may be performed by one processor or by multiple processors. That is, when a first operation, a second operation, and a third operation are performed by a method according to one or more embodiments, the first operation, the second operation, and the third operation may all be performed by the first processor, or the first operation and the second operation may be performed by the first processor (160) and the third operation may be performed by the second processor (160).

[0117] One or more processors may be implemented as a single-core processor (160) including one core, or may be implemented as one or more multi-core processors (160) including multiple cores (e.g., homogeneous multi-cores or heterogeneous multi-cores). When one or more processors are implemented as a multi-core processor, each of the multiple cores included in the multi-core processor may include internal processor memory, such as cache memory or on-chip memory, and a common cache shared by the multiple cores may be included in the multi-core processor. In addition, each of the multiple cores (or some of the multiple cores) included in the multi-core processor may independently read and execute a program instruction for implementing a method according to one or more embodiments of the present disclosure, or all (or some) of the multiple cores may be linked to read and execute a program instruction for implementing a method according to one or more embodiments of the present disclosure.

[0118] When a method according to one or more embodiments of the present disclosure includes a plurality of operations, the plurality of operations may be performed by one core among the plurality of cores included in a multi-core processor, or may be performed by the plurality of cores. For example, when a first operation, a second operation, and a third operation are performed by a method according to one or more embodiments, the first operation, the second operation, and the third operation may all be performed by a first core included in the multi-core processor, or the first operation and the second operation may be performed by a first core included in the multi-core processor, and the third operation may be performed by a second core included in the multi-core processor.

[0119] In embodiments of the present disclosure, the processor (160) may mean a system on a chip (SoC) in which one or more processors and other electronic components are integrated, a single-core processor, a multi-core processor, or a core included in a single-core processor or a multi-core processor, wherein the core may be implemented as a CPU, a GPU, an APU, a MIC, a DSP, an NPU, a hardware accelerator, or a machine learning accelerator, but embodiments of the present disclosure are not limited thereto.

[0120] The operation of the processor (160) for implementing various embodiments of the present disclosure may be implemented through a plurality of modules.

[0121] Specifically, data for a plurality of modules according to the present disclosure can be stored in a memory (105), and the processor (160) can access the memory (105) to load the data for the plurality of modules into a memory or buffer within the processor (160), and then implement various embodiments according to the present disclosure using the plurality of modules.

[0122] However, at least one of the plurality of modules according to the present disclosure may be implemented in hardware and included in the processor (160) in the form of a system on chip.

[0123] Alternatively, at least one of the plurality of modules according to the present disclosure may be implemented as a separate external device, and the electronic device (100) and each module may communicate and perform operations according to the present disclosure.

[0124] According to one or more embodiments of the present disclosure, the processor (160) may control the operation of the electronic device (100) described with reference to the drawings below. At this time, the processor (160) may control at least one of the components of the electronic device (100) so that the electronic device (100) performs each operation.

[0125] Hereinafter, the operation of the electronic device (100) according to the present disclosure will be described in detail with reference to the attached drawings.

[0126] FIG. 3 is a flowchart illustrating a method for operating an electronic device (100) according to one or more embodiments of the present disclosure based on an inclination of the electronic device (100).

[0127] Referring to FIG. 3, the electronic device (100) can obtain information about a first angle between the direction in which one side of the electronic device (100) is facing and the ground (S310). Here, the one side may be one side of the main body (10) including the projection unit (140).

[0128] At this time, the electronic device (100) can sense information about the angle between the direction in which one side of the electronic device (100) is facing and the ground (the pitch angle of the electronic device (100)) through the sensor (155).

[0129] In the present disclosure, when one side of the electronic device (100) faces a wall, the angle between the direction in which the one side of the electronic device (100) faces and the ground may be 90 degrees.

[0130] And, when one side of the electronic device (100) faces the ceiling, the angle between the direction in which one side of the electronic device (100) faces and the ground may be 180 degrees.

[0131] And, when the electronic device (100) is fixed to the ceiling and one side of the electronic device (100) faces the floor, the angle between the direction in which one side of the electronic device (100) faces and the ground may be 0 degrees.

[0132] The electronic device (100) can identify whether the first angle satisfies the first condition (S320).

[0133] Here, the first condition may be a condition in which the first angle is a specific angle. For example, the first condition may be a condition in which the first angle is 90 degrees or 0 degrees.

[0134] Alternatively, the first condition may be a condition where the first angle falls within a specific angle range. For example, the first condition may be a condition where the detected angle falls within the range of '80 to 110 degrees' or '-10 to 10 degrees'.

[0135] If the first angle satisfies the first condition (S320-Y), the electronic device (100) can operate in a first state in which an image is projected onto the floor using the projection unit (140) (S340).

[0136] For example, as illustrated in FIG. 4, when the electronic device (100) is placed on the ground (20), the first angle detected may be 90 degrees. In addition, the first condition may be a condition in which the first angle is 90 degrees. At this time, referring to FIG. 4, the electronic device (100) may project an image (400) onto the ground using the projection unit (140).

[0137] The electronic device (100) can identify whether the first angle satisfies the second condition (S330).

[0138] If the first angle does not satisfy the first condition (S320-N) and the first angle satisfies the second condition (S330-Y), the electronic device (100) can operate in a second state in which an image is projected onto a wall using the projection unit (140) (S350).

[0139] For example, when the electronic device (100) is placed on the ground as illustrated in FIG. 5, the detected second angle may be 180 degrees. In addition, the second condition may be a condition in which the first angle is 180 degrees. At this time, referring to FIG. 5, the electronic device (100) may project an image (500) onto a wall surface (21) using a projection unit (140).

[0140] Meanwhile, if the first angle does not satisfy the first condition (S320-N) and the first angle does not satisfy the second condition (S330-N), the electronic device (100) can re-acquire information about the first angle (S310).

[0141] Meanwhile, when a user input for an image projected onto the floor is detected while operating in the first state at step S340, the electronic device (100) can perform a function corresponding to the detected user input (S360).

[0142] Specifically, while operating in the first state, the electronic device (100) can detect user input for an image projected onto the floor.

[0143] At this time, the user input for the projected image may be a user touch input in which the user touches a point of the image projected on the floor, but is not limited thereto, and the user input for the projected image may be received from an external device or obtained through a user interface (120).

[0144] In the present disclosure, the electronic device (100) may operate in a first input state in which it obtains user input through a user touch input. Alternatively, the electronic device (100) may operate in a second input state in which it obtains user input through an external device or a user interface (120).

[0145] The electronic device (100) can obtain information on the input coordinates of a user touch input using a laser (145) and a camera (150).

[0146] Referring to FIG. 6, the electronic device (100) can project light (610) toward the floor surface via a laser (145) while operating in the first state. At this time, the electronic device (100) can project light (610) toward the floor surface on which the image is being projected. In addition, the electronic device (100) can project light (610) parallel to the floor surface.

[0147] In addition, the electronic device (100) can detect light (620) reflected by the user's hand (630) through the camera (150) included on one side of the main body (10) and perform a function corresponding to the user input position.

[0148] Specifically, light (610) projected by the laser (145) can be reflected by the user's hand (630). The light (630) reflected by the user's hand (630) can be detected by the camera (150). Accordingly, the electronic device (100) can identify the point where the light (610) projected by the laser (145) is reflected as the point where the user's hand (630) touches.

[0149] At this time, the electronic device (100) can identify the coordinates of the point touched by the user. Here, the coordinates may mean the xy coordinates of the point touched by the user in the projected image.

[0150] When the coordinates of the point touched by the user are identified, the electronic device (100) can perform a function corresponding to the coordinates. That is, the electronic device (100) can perform a function corresponding to the user input location.

[0151] For example, the electronic device (100) may project a screen including a plurality of items. In this case, the projected image may include a UI that allows selection of one of the plurality of items.

[0152] When a user input is detected during image projection to select a location where one of multiple items is located, the electronic device (100) may project an image of detailed information about the selected item. For example, if the selected item is content, the electronic device (100) may project an image of the content being played.

[0153] Meanwhile, according to one or more embodiments of the present disclosure, the electronic device (100) can project an image on a curved floor.

[0154] At this time, as illustrated in Fig. 7, when a user touches a curved floor (22), a problem may arise where the light projected onto the laser is not reflected by the user's hand. Accordingly, even when the user touches the floor, the user's touch input may not be detected.

[0155] In this case, the electronic device (100) of the present disclosure can detect a user's touch input by changing the projection height or projection angle at which the laser projects light.

[0156] FIG. 8 is a flowchart illustrating a method for an electronic device (100) according to one or more embodiments of the present disclosure to detect a user's touch input by changing a projection height or projection angle of a laser.

[0157] Referring to FIG. 8, the electronic device (100) can project an image onto a floor surface (S810).

[0158] While an image is projected on the floor, the electronic device (100) can acquire an image of the floor on which the image is projected through a camera (150) (S810).

[0159] The electronic device (100) can identify whether the user's hand is present in the image captured of the floor surface (S830).

[0160] According to one or more embodiments of the present disclosure, the memory (105) may store a neural network model trained to determine whether a user's hand is present in an image when an image is input. Alternatively, the memory (105) may store a neural network model trained to determine whether a user's hand touches a point on the floor when an image is input.

[0161] At this time, the electronic device (100) can input the image captured by the camera (150) into the neural network model stored in the memory (105) to identify whether the user's hand exists in the image captured by the projection surface (S830).

[0162] If the user's hand is not present in the image captured on the projection surface (S830-N), the electronic device (100) can continue to perform the operation of projecting the image on the floor (S810).

[0163] If the user's hand is present in the image captured by the projection surface (S830-Y), the electronic device (100) can identify whether the light projected by the laser (145) is reflected by the user's hand (S840).

[0164] If the light projected by the laser (145) is not reflected by the user's body (S840-N), the electronic device (100) can change the height at which the laser projects the light or the angle at which the laser projects the light (S850).

[0165] Specifically, the electronic device (100) can change the height at which the laser projects light, as illustrated in FIG. 9. Accordingly, the light projected by the laser can be reflected by the user's hand.

[0166] Alternatively, the electronic device (100) may increase the angle at which the laser projects light, as illustrated in FIG. 10. Here, the angle at which the laser projects light may refer to the angle between the direction in which the laser projects light and the ground.

[0167] Accordingly, even when the user touches a curved floor surface, the light projected by the laser (145) can be reflected by the user's hand.

[0168] When the height or angle at which the laser projects light is changed, the electronic device (100) can detect the light reflected by the user's hand through the camera (150).

[0169] When light reflected through the camera (150) is detected, the electronic device (100) can detect a user's touch input (S860). Then, the electronic device (100) can perform a function corresponding to the point touched by the user.

[0170] Meanwhile, the embodiments of FIGS. 9 and 10 described above in step S850 are not implemented individually, and the electronic device (100) may also change the height at which the laser projects light and the angle at which the laser projects light together.

[0171] According to one or more embodiments of the present disclosure, at step S850, the electronic device (100) may provide information guiding the user to reposition the electronic device (100) to a flat surface or a surface with few curves without changing the height or angle at which the laser projects light.

[0172] For example, the electronic device (100) may display text such as “The touch input cannot be recognized because the floor surface is curved. Please move to a flat surface.” or output voice such as “The touch input cannot be recognized because the floor surface is curved. Please move to a flat surface.”

[0173] Accordingly, when the position of the electronic device (100) changes, the electronic device (100) can detect user touch input through the laser (145) and the camera (150).

[0174] Meanwhile, according to the above description, only the case where the pitch angle of the electronic device (100) changes has been described, but the electronic device (100) may project an image differently as the roll angle of the electronic device (100) changes.

[0175] Here, the roll angle may mean the angle between the direction in which one side (11) including the projection unit (140) of the main body (10) and the adjacent side (12) face and the floor surface, as described above.

[0176] FIG. 11 is a flowchart illustrating a method for an electronic device according to one or more embodiments of the present disclosure to project an image according to a change in the inclination of the electronic device.

[0177] Referring to FIG. 11, the electronic device can obtain information about the second angle between the surface and the ground through the sensor (155) (S1110).

[0178] The electronic device (100) can identify whether the second angle satisfies the third condition (S1120).

[0179] If the second angle satisfies the third condition (S1120-Y), the electronic device (100) can project an image at a first ratio in which the width of the image is greater than the height of the image using the projection unit (140) (S1130).

[0180] Here, the third condition may be a condition where the second angle is a specific angle or falls within a specific angle range. For example, the third condition may be a condition where the second angle is 90 degrees.

[0181] At this time, the projection surface on which the electronic device (100) projects the image at the first ratio may be a floor or a wall. If the first angle satisfies the first condition, the electronic device (100) can project the image at the first ratio on the floor. And, if the first angle satisfies the second condition, the electronic device (100) can project the image at the first ratio on the wall.

[0182] The state in which the electronic device projects an image at the first aspect ratio may be referred to as the “landscape state.”

[0183] If the second angle does not satisfy the third condition and the second angle satisfies the fourth condition (S1120-N), the electronic device (100) can project an image at a second ratio in which the width of the image is smaller than the height of the image using the projection unit (140) (S1140).

[0184] Here, the fourth condition may be a condition where the second angle is a specific angle or falls within a specific angle range. For example, the fourth condition may be a condition where the second angle is 0 degrees or 180 degrees.

[0185] At this time, the projection surface on which the electronic device (100) projects the image at the second ratio may be a floor or a wall. If the first angle satisfies the first condition, the electronic device (100) can project the image at the second ratio on the floor. And, if the first angle satisfies the second condition, the electronic device (100) can project the image at the second ratio on the wall.

[0186] The state in which the electronic device projects an image at a second aspect ratio may be referred to as the “portrait state.”

[0187] Meanwhile, according to one or more embodiments of the present disclosure, when a change in the pitch angle of the main body (10) is detected while the electronic device (100) is operating in a second state in which an image is projected onto a wall, the electronic device (100) may switch its operating state to a first state in which an image is projected onto the floor. This will be described in detail with reference to FIG. 12.

[0188] FIG. 12 is a flowchart illustrating a method for controlling an operating state of an electronic device (100) according to one or more embodiments of the present disclosure as the inclination of the electronic device (100) changes.

[0189] Referring to FIG. 12, the electronic device (100) can operate in a second state of projecting an image onto a wall using a projection unit (140) (S1210).

[0190] While the electronic device (100) operates in the second state, the electronic device (100) may operate in a second input state. Here, the second input state may be a state in which the electronic device (100) receives a user input for an image projected from an external device (e.g., a remote control). In the present disclosure, the second input state may be referred to as a “remote control input state” or an “external device input state.”

[0191] Meanwhile, in the present disclosure, the type of image projected onto a wall or floor may correspond to the input state of the electronic device (100). When the input state of the electronic device (100) is a second input state, the electronic device (100) may project a UI element indicating an activated item among a plurality of items. In addition, when the input state of the electronic device (100) is a first input state that receives a user input through a user touch input, the electronic device (100) may project an image without a UI element indicating an activated item among a plurality of items.

[0192] Specifically, when the projected image is an image including a UI for selecting one of a plurality of items, and the input state of the electronic device (100) is a second input state, the electronic device (100) may also project a UI element indicating an activated item among the plurality of items. In the present disclosure, “activation” may be replaced with a term such as “focus.”

[0193] Here, the UI element representing the currently active item can also display detailed information about the currently active item.

[0194] For example, as illustrated in FIG. 13, the electronic device (100) may project an image (1310) that displays a UI element (1330) indicating a currently activated item (1320) among a plurality of items. If the activated item (1320) is a specific content, the electronic device (100) may also project a UI element (1340) for displaying detailed information about the content, such as the production year or genre of the specific content.

[0195] At this time, when a user input for the projected image is detected, the electronic device (100) can project an image corresponding to the acquired user input.

[0196] For example, if a corresponding user input such as up, down, left, or right is received while an image such as that illustrated in FIG. 13 is being projected, the electronic device (100) can change the activated item. Furthermore, if a user input such as confirmation or selection is received, the electronic device (100) can project an image of the activated item being selected. If the activated item is content, the electronic device (100) can project a content playback image.

[0197] Meanwhile, the electronic device (100) can rotate so that the first angle changes from a state satisfying the second condition to a state satisfying the first condition (S1220). At this time, the electronic device (100) can identify whether the first angle changes to a state satisfying the first condition through the sensor (155).

[0198] While the image is projected onto the wall, the electronic device (100) can detect a change in the inclination of the electronic device (100). Specifically, the electronic device (100) can detect a change in the first angle between one side of the main body (10) and the ground.

[0199] According to one or more embodiments of the present disclosure, while the electronic device (100) is rotating, the electronic device (100) can perform an operation to change the size of the projected image.

[0200] Specifically, the electronic device (100) can project an image in a first size on a wall surface when operating in the second state, and can project an image in a second size on a floor surface when operating in the first state. In this case, the first size may be larger than the second size.

[0201] According to one or more embodiments of the present disclosure, while the electronic device (100) is rotating, or after the rotation of the electronic device (100) is completed, the electronic device (100) can identify whether to switch the input state of the electronic device (100) from a second input state to a first input state.

[0202] Here, the first input state may be a state in which the electronic device (100) acquires user input through a user touch input. In the present disclosure, the “first input state” may be referred to as a “touch input state.”

[0203] Specifically, if movement of the external device is detected, the electronic device (100) can maintain the second input state. And, if movement of the external device is not detected, the electronic device (100) can switch to the first input state.

[0204] Alternatively, if the type of image being projected satisfies a preset condition, the electronic device (100) may maintain the second input state. For example, if the type of image being projected is content playback, the electronic device (100) may maintain the second input state.

[0205] Alternatively, when a user input is received from an external device, the electronic device (100) may maintain the second input state. If no user input is received from the external device for a preset period of time, the electronic device (100) may switch to the first input state. Alternatively, when a user input is detected from the external device to switch the input state of the electronic device (100) to the first input state, the electronic device (100) may switch to the first input state.

[0206] Alternatively, if the laser (145) or the camera (150) is not included in or connected to the electronic device (100), the electronic device (100) may remain in the second input state. If the laser (145) and the camera (150) are included in or connected to the electronic device (100), the electronic device (100) may transition to the first input state.

[0207] Alternatively, if the presence of the user's hand is identified in the image captured by the camera (150), the electronic device (100) may switch to the first input state. At this time, the electronic device (100) may identify whether the user's hand is present in the same manner as the operation of step S830.

[0208] According to one or more embodiments of the present disclosure, while the electronic device (100) rotates, the electronic device (100) can identify a projection surface for projecting an image onto the floor.

[0209] The electronic device (100) can capture an image of the floor surface through the camera (150) while rotating and identify a suitable projection surface to project the image on the floor surface.

[0210] The electronic device (100) can continuously project images from the wall surface to the floor surface while rotating. Alternatively, the electronic device (100) can stop projecting images while rotating and resume projecting images once the rotation of the electronic device (100) is complete.

[0211] When the rotation of the electronic device (100) is completed, the electronic device (100) can operate in a second state in which it projects an image onto the floor (S1230). At this time, the electronic device (100) can project an image onto the projection surface of the identified floor.

[0212] While operating in the second state of projecting an image onto the floor, if the input state of the electronic device (100) is the first input state, the electronic device (100) can project an image corresponding to the first input state onto the floor.

[0213] That is, when the input state is switched from the second input state to the first input state, the electronic device (100) can display an indication that the input state has been switched to the first input state through a projected image.

[0214] For example, when the input state of the electronic device (100) is the first input state, the electronic device (100) may project an image (1410) including a UI for selecting one of a plurality of items, as illustrated in FIG. 14. At this time, the electronic device (100) may project the image by deleting the UI element for displaying the activated item described with reference to FIG. 13.

[0215] According to one or more embodiments of the present disclosure, when a change in the pitch angle of the main body (10) is detected while the electronic device (100) is operating in a first state in which an image is projected onto a floor, the electronic device (100) can switch its operating state to a second state in which an image is projected onto a wall. This will be described in detail with reference to FIG. 15.

[0216] FIG. 15 is a flowchart illustrating a method for controlling an operating state of an electronic device (100) according to one or more embodiments of the present disclosure as the inclination of the electronic device (100) changes.

[0217] Referring to FIG. 15, the electronic device (100) can operate in a first state in which an image is projected onto the floor using a projection unit (140) (S1510).

[0218] While the electronic device (100) is operating in the first state, the electronic device (100) may operate in the first input state. At this time, the electronic device (100) may project an image (1410) as described with reference to FIG. 14.

[0219] The electronic device (100) can rotate so that the first angle changes from a state satisfying the first condition to a state satisfying the second condition (S1520).

[0220] Accordingly, the electronic device (100) can operate in a second state of projecting an image on the floor (S1530).

[0221] When the rotation of the electronic device (100) is completed so that the first angle changes to a state satisfying the second condition, the electronic device (100) can switch the input state from the first input state to the second input state. At this time, the electronic device (100) can deactivate the laser (145) and camera (150) for detecting the user touch input.

[0222] And, when the input state is switched from the first input state to the second input state, the electronic device (100) can display an indication that the input state has been switched to the second input state through a projected image.

[0223] For example, when the input state of the electronic device (100) is the first input state, the electronic device (100) may project an image (1310) including a UI for selecting one of a plurality of items, as illustrated in FIG. 14. At this time, the electronic device (100) may project the image by adding UI elements (1320, 1330) for displaying an activated item, as described with reference to FIG. 13.

[0224] FIG. 16 is a drawing for explaining a control method of an electronic device according to one or more embodiments of the present disclosure.

[0225] Referring to FIG. 16, the electronic device (100) can obtain information about a first angle between the direction in which one side of the electronic device (100) is facing and the ground (S1610).

[0226] If the first angle satisfies the first condition, the electronic device (100) can operate in a first state in which an image is projected onto the floor using the projection unit (140) (S1620).

[0227] When a user input is detected for an image projected onto the floor while operating in the first state, the electronic device (100) can perform a function corresponding to the detected user input (S1630).

[0228] Specifically, while operating in the first state, the electronic device (100) can project light toward the floor via a laser included in one surface. Furthermore, the electronic device (100) can detect light reflected by a user's body near the floor via a camera included in one surface, thereby performing a function corresponding to the input location of the user input. In the present disclosure, the user's body near the floor may refer to the user's hand or the user's finger.

[0229] Meanwhile, if the light projected by the laser is not reflected by the user's body near the floor while the user touches the floor, the electronic device (100) can change the projection height of the laser. That is, the electronic device (100) can change the projection height of the light projected by the laser.

[0230] Meanwhile, if the first angle satisfies the second condition, the electronic device (100) can operate in a second state of projecting an image onto a wall using the projection unit.

[0231] While operating in the second state, if the first angle satisfies the first condition, the electronic device (100) can change the image projected on the wall and project it on the floor.

[0232] Specifically, while operating in the second state, if the first angle satisfies the first condition, the electronic device (100) can change the type and size of the image projected onto the wall and project it onto the floor.

[0233]

[0234] *According to one or more embodiments of the present disclosure, when a user input for selecting one of a plurality of items included in an image is detected, the electronic device (100) can project information corresponding to the selected item.

[0235] According to one or more embodiments of the present disclosure, while operating in the second state, the electronic device (100) may display detailed information about an activated item among a plurality of items included in the image.

[0236] Meanwhile, information regarding a second angle between the direction in which the other side adjacent to one side of the electronic device (100) faces and the ground can be obtained. At this time, if the second angle satisfies the third condition, the electronic device (100) can project the image onto the floor using the projection unit at a first ratio in which the width of the image is greater than the height of the image. In addition, if the second angle satisfies the fourth condition, the electronic device (100) can project the image onto the floor using the projection unit at a second ratio in which the width of the image is less than the height of the image.
