Referring to FIG. 3 , the light output from the displays 305 and 310 of the wearable AR device is input to the input optical member 320 and transmitted from the output optical member 325 to the user's eyes via the optical waveguide 315. You can check.

4 is a diagram for explaining augmented reality content that moves according to the movement of the means of transportation when a wearable AR device is used in the means of transportation.

A wearable AR device such as AR glasses (augmented reality glass) (eg, the wearable AR device 200 of FIG. 2 ) displays a virtual image (eg, object information) on an image actually viewed by a user wearing the wearable AR device. ), etc. are next-generation devices. For example, the wearable AR device may be a head mounted display (HMD). However, this is only an example, and the wearable AR device may be various types of AR devices. A wearable AR device analyzes information obtained through a camera (eg, the first cameras 245a and 245b in FIG. 2 ), a sensor, and a camera and sensor that recognizes the surroundings, and shows virtual augmented reality content on a screen actually viewed. An optical display may be included.

A user may wear the wearable device on the user's face. Wearable devices perform vision processing processes such as SLAM (simultaneous localization and mapping), head tracking, hand tracking, and surface reconstruction based on data acquired using cameras and sensors. And the augmented reality content can be overlapped with the real environment and shown to the user.

A wearable AR device may generate spatial map data corresponding to a corresponding space in an arbitrary space where information is not given through various sensors such as a camera, GPS, gyro sensor, and acceleration sensor, and determine a user's location.

For example, the wearable AR device may generate space map data corresponding to a space viewed by the user in a mesh form. Space map data may be initially generated for a certain space, and may be generated whenever a new space appears.

The wearable AR device displays a certain part of the space map data to the user based on the current location of the wearable AR device on the space map data determined through various sensors such as a camera, GPS, gyro sensor, and acceleration sensor, and the current direction the wearable AR device is heading. You can decide what to show. Since the user is wearing the wearable AR device, the current location of the wearable AR device may be the user's current location, and the current direction the wearable AR device is facing may be the user's current gaze direction.

When the user wearing the wearable AR device moves or the direction the user is looking at changes, it is possible to determine which part of the generated space map data to show. Spatial map data may be updated when the current location and current direction of the wearable AR device deviate from the generated space map data.

The wearable AR device may determine at least one of a current location or a current direction of the wearable AR device on the spatial map data by using an image obtained through a camera. The current location and current direction of the wearable AR device determined using the image obtained through the camera may be inaccurate, and to compensate for this, the wearable AR device may use an inertial measurement unit (IMU). The inertial value measured by the inertial sensor may also have an error, but can be compensated for by using the camera and the inertial sensor together.

The inertial sensor may include an acceleration sensor, a gyro sensor, and a geomagnetic field sensor. The inertial value may refer to a value output from an inertial sensor. For example, the inertia value may include values of roll, pitch, and yaw. The wearable AR device may adjust the current position and current direction of the wearable AR device on the space map data according to the inertia value, and output augmented reality content according to at least one of the adjusted current position and current direction of the wearable AR device.

Wearable AR devices can be used in transportation such as cars and trains. For example, a user may use a wearable AR device while riding a vehicle or a wearable AR device while riding a train. However, vehicles and trains are only examples, and means of transportation may mean various means of transportation available to users.

Since the vehicle moves, even if the user does not move within the vehicle, the inertial value of the inertial sensor may change due to the movement of the vehicle, and the wearable AR device may recognize that the user has moved. When the wearable AR device determines the current location and current direction of the wearable AR device on spatial map data using only a camera and an inertial sensor, augmented reality content that does not correspond to an actual user's movement may be output, causing user discomfort.

When the user moves within the vehicle, a space that was not visible when the initial space map was created may be newly viewed, and the wearable AR device updates space map data whenever a new space is seen, consuming a lot of computing resources.

For example, referring to FIG. 4 , situations (a, b) in which augmented reality contents 405 including virtual objects are output on the display of the wearable AR device according to the movement of the transportation means 420 are shown. .

In the situation of FIG. 4 (a) in which the user 435 wearing the wearable AR device faces the front and the vehicle 420 is driving straight, the user 435 and the wearable AR device do not move, so the user ( In operation 435 , it may be expected that the previous augmented reality content 405 will be output unchanged like the augmented reality content 415 at the present time. The wearable AR device may recognize the straight movement of the vehicle 420 and output augmented reality content 410 in which virtual objects move closer to the user 435 . Since the augmented reality content 410 does not correspond to the motion of the wearable AR device and the user 435, the purpose of providing the augmented reality content may not be achieved.

Similarly, in the situation of FIG. 4 (b) in which the user 435 wearing the wearable AR device is facing the front and the transportation means 420 is driving on a curve, the user 435 may view the previous augmented reality content 405 at the present time. ) can be expected to be output without changing like the augmented reality content 430 . The wearable AR device may recognize the curved movement of the vehicle 420 and output augmented reality content 425 in which virtual objects move closer to the left side of the user 435 . Since the augmented reality content 425 does not correspond to the motion of the wearable AR device and the user 435, the purpose of providing the augmented reality content may not be achieved.

The wearable AR device according to an embodiment may operate based on whether or not the wearable AR device is within the space of the vehicle 420 . Whether the wearable AR device is within the space of the vehicle 420 may be manually determined according to the user 435's selection, or may be automatically determined as shown in FIG. 5 .

The case of manual determination will be described below with reference to FIG. 18 .

If it is determined automatically, the wearable AR device determines whether the wearable AR device is the vehicle 420 based on at least one of information received from the vehicle 420 or a value measured using at least one sensor of the wearable AR device. You can determine whether or not you are within space.

In one embodiment, the wearable AR device determines the space around the wearable AR device based on a value measured using at least one sensor of the wearable AR device when it is determined that the wearable AR device is not within the space of the vehicle 420. Augmented reality content corresponding to may be output.

For example, when it is determined that the wearable AR device is not within the space of the vehicle 420, the wearable AR device determines the space where the wearable AR device is located based on a value measured using at least one sensor of the wearable AR device. At least one of a current location and a current direction of the wearable AR device may be determined from corresponding space map data, and augmented reality content corresponding to the current location and current direction of the wearable AR device determined from the corresponding space map data may be output.

In one embodiment, the wearable AR device determines whether there are anchor devices capable of communicating with the wearable AR device when it is determined that the wearable AR device is within the space of the vehicle 420, and if there are anchor devices capable of communicating, the anchor device By communicating with the devices, augmented reality content corresponding to the space of the vehicle 420 around the wearable AR device may be output.

An anchor device may refer to a device capable of determining a positional relationship between the wearable AR device and the anchor device, such as a distance, an angle, and/or a direction, by communicating with the wearable AR device. For example, the anchor device may be a UWB device that transmits and receives an ultra-wideband signal.

In one embodiment, anchor devices may be registered with a wearable AR device.

For example, if there are anchor devices capable of communicating with the wearable AR device within the space of the vehicle 420, the wearable AR device can receive signals transmitted by the anchor devices, and the wearable AR device can receive signals transmitted by the anchor devices. When a corresponding signal is received, it may be determined that there are anchor devices capable of communication.

In another example, when there are anchor devices capable of communicating with the wearable AR device within the space of the vehicle 420, the anchor devices receive a signal transmitted by the wearable AR device and in response to the signal transmitted by the wearable AR device An anchor response signal may be transmitted. When receiving response signals from the anchor devices, the wearable AR device may determine that there are anchor devices capable of communication.

When it is determined that the wearable AR device is within the space of the vehicle 420, the wearable AR device determines whether there are anchor devices capable of communicating with the wearable AR device of the wearable AR device, and if there are anchor devices capable of communicating, the anchor device determine at least one of the current location of the wearable AR device or the current direction to which the wearable AR device is heading from the first space map data corresponding to the space of the vehicle 420 by communicating with the vehicle 420, and determining the wearable AR device from the first space map data Augmented reality content corresponding to the current location and current direction of the device may be output.

Augmented reality content corresponding to the movement of the wearable AR device in the space where the wearable AR device is located may be provided according to whether or not the wearable AR device according to an embodiment is within the space of the vehicle 420 .

You can decide whether there is. For example, the wearable AR device may determine whether the wearable AR device is within the space of the vehicle based on at least one of information received from the vehicle or a value measured using at least one sensor of the wearable AR device. . Operation 505 is described below with reference to FIGS. 6-9.

If it is determined in operation 505 that the wearable AR device is not within the space of the vehicle, the wearable AR device, in operation 520, detects the wearable AR based on a value measured using at least one sensor of the wearable AR device. Augmented reality content corresponding to a space around the device may be output.

For example, the wearable AR device determines the current location of the wearable AR device or the wearable AR device in space map data corresponding to a space where the wearable AR device is located, based on a value measured using at least one sensor of the wearable AR device. It is possible to determine at least one of the current directions towards.

The wearable AR device may output augmented reality content corresponding to the current location and current direction of the wearable AR device on the corresponding spatial map data of the surrounding space.

If it is determined in operation 505 that the wearable AR device is within the space of the vehicle, in operation 530, the wearable AR device may obtain first space map data corresponding to the space of the vehicle.

In an embodiment, the wearable AR device may generate second space map data corresponding to the space of the vehicle around the wearable AR device within the space of the vehicle.

The wearable AR device may determine whether there is previously generated third space map data for the space of the vehicle. When there is third space map data, the wearable AR device may generate first space map data by combining the third space map data and the second space map data.

The wearable AR device may determine whether there is spatial information about the space of the vehicle. For example, the spatial information may include information about dimensions of a vehicle's space and components, such as seats, included in the space. If there is space information, the wearable AR device may convert the corresponding space information into fourth space map data and generate first space map data by combining the fourth space map data with the second space map data.

The wearable AR device may generate first space map data by combining fourth space map data converted from space information, third space map data and second space map data previously generated for the space of the vehicle.

When there is no space information, the wearable AR device may use the second space map data as first space map data corresponding to the space of the vehicle.

In one embodiment, the wearable AR device generates the first space map data based on the second space map data, the third space map data, and the fourth space map data, so that the space of the vehicle immediately after the user gets on the vehicle Space map data for the entire area may be secured, and the number of updates of the first space map data may be reduced by reducing cases in which the current location and current direction of the wearable AR device deviate from the first space map data.

Operation 530 is further described below with reference to FIGS. 16 and 17 .

In operation 535, the wearable AR device may determine whether there are anchor devices of the vehicle capable of communicating with the wearable AR device. Anchor devices may be used to determine the location of the wearable AR device and the direction the wearable AR device faces. For example, the anchor device may be a UWB device that transmits and receives ultra-wideband signals.

In one embodiment, anchor devices may be registered with a wearable AR device.

For example, if there are anchor devices capable of communicating with the wearable AR device within the space of the vehicle 420, the wearable AR device can receive signals transmitted by the anchor devices, and the wearable AR device can receive signals transmitted by the anchor devices. When a corresponding signal is received, it may be determined that there are anchor devices capable of communication.

In another example, when there are anchor devices capable of communicating with the wearable AR device within the space of the vehicle 420, the anchor devices receive a signal transmitted by the wearable AR device and in response to the signal transmitted by the wearable AR device An anchor response signal may be transmitted. When receiving response signals from the anchor devices, the wearable AR device may determine that there are anchor devices capable of communication.

If it is determined in operation 535 that there are anchor devices capable of communicating with the wearable AR device, in operation 540, the wearable AR device may set reference points corresponding to the positions of the anchor devices in the first spatial map data.

For example, the wearable AR device may determine an initial positional relationship between the wearable AR device and the anchor devices by communicating with the anchor devices while the vehicle is stopped. The initial positional relationship may include, for example, an initial distance and an initial angle between the wearable AR device and anchor devices. The wearable AR device determines points corresponding to the positions of the anchor devices in the first spatial map data based on the value measured using at least one sensor of the wearable AR device and the initial positional relationship, and sets the points as reference points. can

In operation 575, the wearable AR device may output augmented reality content corresponding to the determined current location and direction of the wearable AR device on the first spatial map data.

For example, in the case of situation (a) in FIG. 4, even if the vehicle moves, the positional relationship between the anchor devices in the vehicle and the user wearing the wearable AR device does not change, so the wearable AR device is the same as the previous augmented reality content 405. Augmented reality content 415 may be output to the same location as the .

In operation 535, if there are no anchor devices capable of communicating with the wearable AR device, in operation 555, the wearable AR device receives an inertia value of the vehicle from at least one of the vehicle or an electronic device located in the space of the vehicle. You can decide whether you can or not.

If it is determined in operation 555 that the wearable AR device can receive the inertia value of the vehicle, in operation 565, the wearable AR device measures the inertia value of the vehicle through an inertial sensor of the wearable AR device. Inertia values can be calibrated.

For example, when a means of transportation is moving, the inertia value measured through the inertial sensor of the wearable AR device includes the inertia value due to the movement of the means of transportation, so the wearable AR device measures the inertia measured through the inertial sensor of the wearable AR device. The inertial value of the wearable AR device may be corrected based on the difference between the value and the inertial value of the vehicle. Correction of the inertia value will be described below with reference to FIG. 14 .

In operation 565, an initial position of the wearable AR device on the first spatial map data and an initial direction to which the wearable AR device faces may be determined based on the image obtained through the camera of the wearable AR device and the corrected inertial value.

In operation 570, the wearable AR device sets the wearable AR device on the first spatial map data based on the inertial value of the vehicle, the inertial value of the wearable AR device, and the initial position and initial direction of the wearable AR device on the first spatial map data.

It is possible to determine the inertia value by a user's movement. The wearable AR device applies the determined inertia value due to the user's motion to the initial position and initial direction of the wearable AR device on the first space map data to determine at least one of the current position or current direction of the wearable AR device on the first space map data. can decide

Operation 570 is described below with reference to FIG. 15 .

In operation 575, the wearable AR device may output augmented reality content corresponding to the determined current location and direction of the wearable AR device on the first spatial map data.

If it is determined in operation 555 that the wearable AR device cannot receive the inertia value of the vehicle, the wearable AR device, in operation 580, displays a first space based on an image obtained through a camera of the wearable AR device. An initial location of the wearable AR device on the map data and an initial direction toward which the wearable AR device faces may be determined.

In operation 585, a current location of the wearable AR device on the first spatial map data and a current direction the wearable AR device is heading may be determined based on an image obtained through a camera of the wearable AR device.

For example, the wearable AR device determines a second amount of change in the position and direction of the wearable AR device by using an image acquired through a camera, and the second amount of change is the initial position of the wearable AR device on the first space map data and the initial A current location and current direction of the wearable AR device on the first space map data may be determined by applying the direction.

If the current location and current direction of the user on the first space map data are determined in operation 580, in operation 575, the wearable AR device performs augmentation corresponding to the determined current location and current direction of the user on the first space map data. Actual content can be output.

In another embodiment, operations 580, 585, and 575 may be performed when there is no anchor device capable of communicating with the wearable AR device in operation 535.

In another embodiment, the wearable AR device may be connected to another electronic device (eg, the electronic device 101 of FIG. 1 ), and operations 505, 520, 530, 535, 540, 550, 555, 565, 570, Operations 575, 580, and 585) may be performed by an electronic device connected to the wearable AR device. For example, the wearable AR device transmits information obtained through sensors of the wearable AR device to an electronic device connected to the wearable AR device, and the electronic device connected to the wearable AR device processes the information transmitted from the wearable AR device to perform one operation. The augmented reality providing method according to the example may be performed.

In operation 605, the wearable AR device (eg, the wearable AR device 200 of FIG. 2) may determine a distance between the vehicle and the wearable AR device. For example, the wearable AR device may communicate with the anchor device of the vehicle to determine a distance between the vehicle and the wearable AR device when the vehicle has an anchor device.

In operation 610, the wearable AR device may determine whether the determined distance is less than or equal to a set distance. If the determined distance exceeds the set distance, the wearable AR device may determine, in operation 625, that the wearable AR device is not within the space of the vehicle.

The wearable AR device may determine that the boarding condition is satisfied when a new passenger is detected in the vehicle, and may determine that the boarding condition is not satisfied when no new passenger is detected in the vehicle.

If the boarding condition is not satisfied in operation 620, the wearable AR device may determine that the wearable AR device is not within the space of the vehicle in operation 625.
