However, for convenience of explanation, it is assumed that a design target is a desk.

1 shows an example of a structure of a furniture designing apparatus. The furniture designing apparatus includes an attitude recognizing apparatus 50, a head-mounted display apparatus 100, and an input apparatus 80. [

The posture recognizing device 50 is a device for recognizing the posture of the user. The attitude recognition device 50 can recognize the attitude of the user by using a camera and a sensor. The posture recognizing device 50 can recognize the posture of the user by using various image processing techniques. The posture recognizing device 50 may utilize a commercialized device. For example, the posture recognizing device 50 may be a device such as Kinect of Microsoft Corporation. The attitude recognition device 50 basically acquires an image including a user by using a camera, and analyzes the image to grasp the attitude of the user. Furthermore, the posture recognizing device 50 may recognize the user posture in the three-dimensional space based on the depth information using a stereo camera. The attitude recognition device 50 may recognize the user by using an infrared beam projector and an infrared camera, such as a Kinect.

The posture recognizing device 50 can recognize the operation of the user in the three-dimensional space. The posture recognizing device 50 recognizes a gesture caused by movement of a user, movement of a user's specific body part, and movement of a body part. Here the gesture can be used as a specific input command.

The posture recognizing device 50 recognizes the user in the image and recognizes the user's posture in real time by identifying the positions of the plurality of body parts of the user. The attitude recognition device 50 recognizes the user in the image and obtains the position of the user's body part. The attitude recognition device 50 acquires attitude information of the current user based on the user's body position. The posture information may include position of a specific body part, position of a specific body part in a three-dimensional space, length of a specific body part, distance between a plurality of body parts, angle of a specific body part determined by plural positions, Angle, and the like.

The head-mounted display device 100 is worn on the head portion of the user. The head mount display device 100 provides a realistic image according to the position and direction of the user's eyes. The head-mounted display device 100 receives attitude information from the attitude recognition device 50. [ Through this, the head mount display device 100 acquires the current posture of the user, and generates information or visual data for furniture design based on attitude information. On the other hand, the head-mounted display device 100 may receive position information of a plurality of body parts from the attitude recognition device 50, and determine the attitude of the user based on the received position information.

The head-mounted display device 100 outputs an object for furniture design to the screen. The head-mounted display device 100 can receive a user's command to select a specific object displayed on the screen, and output a furniture object having a modified design according to the command. Wherein the user command comprises at least one of a user gesture determined by image analysis, an instruction received from a separate input device, and an instruction determined by speech recognition.

The head mounted display device 100 includes a communication device 110, a storage device 120, a sensor device 130, a control circuit 140, and an output device 150.

The communication device 110 receives specific data from an external object. The communication device 110 receives attitude information from the attitude recognition device 50. [ The communication device 110 may receive information from the input device 80. Further, the communication device 100 can receive data about furniture objects, application data for furniture design, and the like from the server. The communication device 100 can receive data using at least one of various communication methods such as short-distance communication (Bluetooth, etc.), Wi-Fi, mobile communication, and the like.

The storage device 120 stores basic data for operation of the head mounted display device 100, data received from the communication device 110, a program for furniture design, design data for a furniture object, and the like. The basic data includes OS, data for program installation and execution, and the like. The design data follows any one of a variety of formats for visually representing objects in a computer device. The storage device 120 may be implemented as an apparatus such as a flash memory, a hard disk, or the like. Further, as will be described later, the storage device 120 may store a model or data for determining guide information.

The head mount display device 100 outputs an image according to the direction of the user's eyes worn by the head mount display device 100. The sensor device 130 senses the position and orientation of the head mounted display device 100. The sensor device 130 may be implemented by various sensors such as an acceleration sensor, a gyro sensor, a geomagnetic sensor, an image sensor, and the like.

The output device 150 is a display device that outputs a furniture object, a screen (interface) for design, and the like.

The control circuit 140 controls the operation of the communication device 110, the storage device 120, the sensor device 130, and the output device 150. For example, the control circuit 140 causes the output device 150 to output a certain object by using the program (app) and data stored in the storage device 120. The control circuit 140 controls the output object according to data input from the communication device 110 and the sensor device 130 to be changed. The control circuit 140 determines guide information to help design the furniture object based on the user's attitude information. The guide information is output through the output device 150. The guide information will be described later. The control circuit 140 includes a computing device capable of performing a constant calculation such as a CPU and an AP. The control circuit 140 may include a memory in which a computing device and a certain program are embedded.

Although not shown in FIG. 1, the head mount display device 100 may include an input interface device for receiving a physical command from a user, a microphone for receiving a user voice, and the like.

The input device 80 is a device that receives a user's command. The input device 80 may receive physical motion from the user. For example, the input device 80 may have various forms such as a keyboard, a mouse, and the like. For example, the user may input a command by pressing a button of the input device 80 held in the hand in a predetermined posture. Accordingly, the user can select a specific object in the virtual space output from the output device 150 according to his / her movement. The user can select a specific part to change the design in the furniture object currently output using the input device 80. [ Further, the input device 80 may be a microphone for receiving a user's voice command. In this case, the head-mounted display apparatus 100 can recognize a voice and receive a specific command. The input device 80 transmits a certain command to the head-mounted display device 100 through wired or wireless communication. The user can change the viewpoint of the screen outputted through the input command (for example, convert from first person to third person), change the screen to be output (change background), change the furniture object to be designed, Start design changes for specific areas of furniture, and finish design changes for specific areas of furniture.

2 is an example of a furniture design using a furniture design apparatus. 2, the furniture designing apparatus includes an attitude recognizing apparatus 50, a head-mounted display apparatus 100, and an input apparatus 80. [ When the gesture of the user is inputted, the physical separate input device 80 may not be used.

2, the dotted-line rectangular area 200 shows an example of a screen output by the head-mounted display device 100. As shown in FIG. The head mount display device 100 basically outputs furniture objects to be designed on the screen. You can design a variety of furniture, but the desk is shown as an example.

The head-mounted display device 100 may output other objects besides furniture objects to the screen. For example, the head-mounted display device 100 can output the same screen as the place where the actual furniture is to be placed on the screen. The head mounted display device 100 can output structures such as walls and columns constituting the building. The head-mounted display device 100 can also output other furniture already placed in the room. For example, if the desk is designed, the head mount display device 100 can output a bookcase, a drawer, etc. already disposed in the study room where the desk is to be placed. This allows the user to design furniture in consideration of the space in which the actual furniture will be placed. The head mount display device 100 holds data on a space, a background, a furniture object, and the like outputted on the screen in advance, and constructs and outputs a screen based on the data.

A furniture object consists of a plurality of parts. The desk shown in Fig. 2 will be described as an example. The furniture object shown in Fig. 2 comprises a desk body and a shelf placed on the desk body. The main body of the desk can be defined as a plurality of parts constituting the desk and a size or a length of each part. The height of the desk (indicated by ①) means the length from the floor to the top of the desk. The width of the desk (indicated by ②) means the length between one side of the desk (the leg) and the other side of the desk. The depth of the desk (marked with ③) means the length between the front of the desk (the side facing the user) and the back. The height of the footrest (denoted by ④) means the length from the floor to the footboard.

The shelf consists of two stages. The height of the first stage shelf (denoted by ⑤) means the length from the bottom surface to the bottom of the first stage shelf. In some cases, unlike FIG. 4, the height of the first stage shelf may be the length from the top of the desk to the bottom of the first shelf. The height of the first shelf (denoted by ⑥) means the length from the bottom to the bottom of the second shelf. The height of the entire shelf (denoted by 7) means the length from the bottom surface to the top surface of the shelf (the top surface of the second shelf in Fig. 4). Although not shown in FIG. 2, the depth of the shelf, the spacing of the partition dividing the shelf uniformly, and the like can be design elements.

3 is an example of designing the configuration of a furniture object. The user can change the design of the furniture object output to the head mounted display device 100. [ The user can select at least one part of the plurality of parts constituting the furniture object and change the layout of the selected part. Wherein the layout is determined by at least one element of a one-way length, a width, a depth, a size and a position of a specific region.

3 (A) shows an example in which the length of a desk is changed. 3 (A) shows an example in which the right side of the desk is extended. In Fig. 3 (A), a dotted line shows a part before change. For example, the user can select the right side of the desk and adjust the length of the desk in such a manner that the right side is held or stretched when the selected side is selected. Alternatively, the user may select a portion to be changed and input the length of the portion to change the layout of the portion. Fig. 3 (B) is an example in which the height of the desk is changed. In Fig. 3 (B), the dotted line represents the extended height. For example, the user can select the top surface of the desk and change the height of the desk by adjusting the height of the top surface. Fig. 3 (C) is an example in which the height of the first stage shelf is changed. 3 (C), the dotted line represents the extended height of the first stage shelf. For example, the user can change the height of the first stage shelf in such a manner that the top surface of the first shelf is selected and the top surface is increased or decreased. 3 (D) shows an example in which the depth of the desk is changed. In Fig. 3 (D), the dotted line indicates the depth of the extended desk. For example, the user can select the top surface of the desk and adjust the depth of the desk by pulling or pushing the top surface.

The manner in which a user changes the layout of a particular part of a furniture object may vary. (1) First, a user must select a specific part of the furniture object to be output to the head-mounted display device 100. The head mounted display device 100 can output an object capable of selecting a specific part of the furniture object together with the furniture object. For example, the head-mounted display device 100 may output an object such as a user's hand to the screen, thereby realizing a state of contacting a specific part according to a user's operation. (i) The user can select a specific region through a specific gesture. (ii) The user may select a corresponding site by using a separate physical input device in a state of being in contact with a specific site on the screen. (iii) The user can select the corresponding region by speech input while in contact with a specific region on the screen. After (2), the user can change the layout of the selected part. (i) The user can change the layout by changing the position or size of the specific part while selecting the specific part. For example, the user can change the layout of the corresponding part by changing the position while pressing the button of the physical input device. (ii) After selecting a specific region, the user can change the layout by inputting information corresponding to the size or position of the region. For example, the user may input a specific numerical value or information through a separate input device or voice input to change the layout of the corresponding part. (iii) The user can select one of the layout samples (eg) displayed on the screen after selecting a specific area and change the layout of the corresponding area.

The head mount display device 100 outputs information (guide information) that helps design a furniture object on a screen for designing a furniture object. The head mount display device 100 can recommend a layout for a specific part constituting the furniture object. For example, the head-mounted display device 100 may recommend at least one of length, height, width, and depth of a specific region. Further, the head-mounted display apparatus 100 may recommend the position of a plurality of furniture when a plurality of furniture is used in a specific space. For example, when a desk and a chair are used together, the position of the chair and the like can be recommended. The guide information can be determined on the basis of the attitude information of the person recognized by the attitude receiver 50. [ The head mount display device 100 outputs customized guide information according to body characteristics (body shape) and attitude characteristics of the user. This allows the user to conveniently design ergonomic furniture. The head-mounted display device 100 can output a desired position or a configurable area of a specific part as guide information.

Figure 4 is an example of factors considered in determining guide information. FIG. 4 shows elements considered in the guide information determination in the form of a table.

In FIG. 4, the types of items to be considered in the guide information determination are exemplified as a body, an object, and a space clearance. Of course, various criteria or items may be used depending on the object to be designed. The body has items such as body posture, body activity, body clearance, and body reachability. Each item is related and functionally redundant. The body posture is related to the desired posture of the user. Physical activity is an item that considers the position or movement of the user's body parts using furniture. The physical free space means the space for the user's body parts using furniture. Physical accessibility is an item that takes into account the reach of the user body using furniture. The convenience of use of the item takes into consideration other things to be used together with the furniture. Free space is an item that represents the free space associated with the furniture itself.

4, the guide information indicates the type of guide information. FIG. 4 is an item considering a desk, and guide information different from FIG. 4 may be used depending on the type of a furniture object. An example in which some guide information is determined will be described with reference to FIGS. 6 to 12. FIG.

In FIG. 4, the guide information variable means a variable to be considered in determining guide information. In FIG. 4, italicized items are static variables, and underlined items are dynamic variables. Dynamic variables can be varied in real time depending on the user's attitude and the design of the furniture object. The head mount display apparatus 100 determines guide information in consideration of a static variable and a dynamic variable that changes in real time, and outputs the most appropriate guide information to the screen.

The guide information can be determined by using more commonly known ergonomic information besides the information shown in FIG.

5 shows an example of outputting guide information. 5 is an example in which guide information is output on the screen of the head-mounted display device 100. FIG. In FIG. 5, the rectangular area is an example of a screen displayed on the screen, and the red arrow is additionally displayed to explain guide information output from the screen.

Fig. 5 (A) shows an example of outputting guide information related to the body posture. 5 (A) shows the back angle and the elbow angle of the user using the desk at the third person view. The angle is expressed in the form of a constant gauge. The gauge is divided into red and green areas, red indicates an inappropriate angle, and green indicates a preferred angle. Thus, the user can determine whether his / her posture is the desired posture. As described above, the guide information differs depending on the dynamic variable. Therefore, the user can design the furniture based on the desired posture by checking whether the current posture is in a desired state.

5 (B) is an example of outputting guide information related to physical activity. 5 (B) is guide information on the height of the desk. And outputs the position of the desk top plate to a predetermined area on the screen. Guide information can be displayed in various ways. Fig. 5 (B) shows the height of the desk in a standing posture as a red dotted line area.

5 (C) shows an example of outputting guide information related to physical activity. FIG. 5C is an example of recommending the height (position) of a monitor corresponding to another object to be used on a desk. The height of the monitor is related to the height of the user's eyes. The head mount display apparatus 100 can output guide information on the monitor height based on the attitude of the user sitting on the chair. FIG. 5 (C) shows the position of the preferred monitor as a dotted area. Furthermore, it is possible to display a monitor disposed at a specific position on the screen.

FIG. 5D shows an example of outputting guide information related to body accessibility. 5D is an example of recommending the height of the shelf. The head mount display device 100 can output guide information about the height of the shelf based on the area where the user can reach the arm based on the current user's attitude information. FIG. 5D shows the position of the shelf in a dotted line on a preferred screen. The upper dotted line corresponds to the upper limit considering the reachability, and the lower dotted line corresponds to the lower limit considering the structure of the shelf or the attitude of the user.

Fig. 5 (E) shows an example of outputting guide information related to convenience of use. FIG. 5 (E) outputs guide information in consideration of an area which can be conveniently accessed by a user using a desk. For example, the head-mounted display apparatus 100 can constantly display an area in which the left hand is accessible and an area in which the right hand is accessible. In addition, the head-mounted display device 100 can display a relatively close distance in a range of a main operation range or main operation angle at a constant distance according to the distance. The main scope of work can be in the range that can be reached when the elbow is placed at the end of the desk. Further, the head-mounted display device 100 can display a relatively long distance constantly in an extended working range or an extended working angle. The extended working range or angle may be reachable when the shoulder is placed at the end of the desk.

5 (F) shows an example of outputting guide information related to the free space. When a chair is used together with a desk, the head mount display apparatus 100 can output the position of a suitable chair as guide information in consideration of the position of the desk. FIG. 5 (F) shows an example of a limit line on which a chair can be placed on the floor.

6 is an example of an element for determining guide information on a desk height. The height of the desk is assumed to be the length from the floor to the top surface of the desk. The guide information for the height of the desk can be displayed as an upper limit and a lower limit. In this case, the user can set the height of the desk between the upper limit line and the lower limit line. 6 (A) is an example of determining the desk height in a sitting posture. 6 (B) is an example of determining the height of the desk in the standing posture. Guide information about desk height can be determined as shown in Table 1 below. The height of the desk below is assumed to be a typing position with a keyboard at the desk.

Item Equation

Sitting position
(Sitting) Physical lower limit line
(Physical Restriction) = seat height + thigh clearance + table top thickness Min Han (Min) = seat height + elbow rest height + elbow end to pivot length- elbow to wrist x sin20 Upper limit (Max) = seat height + elbow rest height + elbow end to pivot length - elbow to wrist length x sin10
Standing posture
(Standing) Min Han (Min) = elbow height + elbow end to pivot - elbow to wrist length x sin20 Upper limit (Max) = elbow height + elbow end to pivot - elbow to wrist length x sin10

Seat height is the height of the chair and is defined as the length from the floor to the top of the chair. Thigh clearance means the thickness of the user's thigh. Table top thickness refers to the thickness of the desk top. The elbow rest height is defined as the length from the top of the chair to the elbow at the sitting posture and the elbow height. The elbow height is defined as the length of the elbow from the floor to the elbow in the standing posture. elbow end to pivot length means the length from the bottom of the elbow to the center of rotation. Finally, "seat height + elbow rest height + elbow end to pivot length" or "elbow height + elbow end to pivot length" represents the distance from the floor surface to the elbow rotation joint in the current user's posture. elbow to wrist length represents the distance from the tip of the elbow to the wrist. The upper limit angle of the elbow rotation for typing with respect to the vertical line is 70 degrees, and the lower limit angle is 100 degrees.

Figure 7 is an example of an element that determines guide information for desk width. The width of the desk is defined as the distance from one end of the desk top to the end in the direction of the desk length. Guide information about the width of the desk can be determined as shown in Table 2 below.

Item Equation Physical limit
(Physical Restriction) = elbow to elbow breadth Main business scope
(Primary work zone) = radius of elbow pivot to handtip length (0-135 degrees) Expanded scope of work
(Secondary work zone) = radius of shoulder to handtip length (0-180 degrees)

The physical limit is the distance between one elbow and the other (elbow to elbow breadth). The minimum width of the desk is defined as the distance between two elbows (width). The elbow pivot is the center of elbow rotation. The elbow pivot to handtip length is the distance from the center of elbow rotation to the handtip. The main task range corresponds to the radius at which the fingertip can rotate with respect to the center of elbow rotation. The main task range was limited to 0-135 degrees (45 degrees on a vertical line) considering the rotation angle of the elbow. The extended working range corresponds to the radius of the fingertip that can rotate around the shoulder. In FIG. 7, the main task range of the left hand is indicated in orange, and the main task range of the right hand is indicated in green. The extended working range of each hand is indicated in yellow. Thus, the width of the desk can be determined according to the area of the work scope. That is, the width of the desk can be determined according to the reachable range of the user's body (hand).

Figure 8 is an example of an element that determines guide information for desk depth. The depth of the desk is defined as the distance from the end of the desk top in the user's direction to the opposite end. Fig. 8 (A) is an example of determining the desk depth in a sitting posture. Fig. 8 (B) is an example of determining the desk depth in the standing posture. Guide information on desk depth can be determined as shown in Table 3 below.

Item Equation Physical lower limit
(Physical Restriction) = buttock-knee length - maximum body depth + knee height x sin20 + foot length x cos20
Upper limit value
(Primary work zone) = shoulder to spine x cos20 - maximum body depth / 2 + square root {shoulder to handtip ^ 2 - (shoulder to handtip x sin20 + spine height - desk height) ^ 2}

The physical lower limit of the depth of the desk can be determined by considering the sitting position. buttock-knee length means the distance from the end of the buttock to the club. The maximum body depth is the longest horizontal distance between the top and bottom of the body. The 'buttock-knee length - maximum body depth' corresponds to the knee depth. The lower limit corresponds to the knee depth plus the horizontal distance from calf to toe. Ultimately, the lower limit corresponds to the distance that the toe reaches from the front of the body while the person is in close contact with the desk as much as possible in a normal posture.

The upper limit of the depth of the desk can be determined in consideration of the standing posture. Shoulder to spine means the distance from the shoulder to the spine where the spine ends. shoulder to handtip means the distance from shoulder to fingertip. The spine height is the distance from the floor to the spine. 'Square root' is the square root of the expression, and '^ 2' is the square operation.

FIG. 9 is an example of an element for determining guide information on shelf height. The height of the line number is defined as the distance from the bottom surface to the top plate of the shelf. Fig. 9 (A) is an example of determining the shelf height in a sitting posture. Fig. 9 (B) is an example of determining the shelf height in the standing posture. Guide information about shelf height can be determined as shown in Table 4 below.

Item Equation Sitting position
(Sitting) Lower limit value = eye height Upper limit (Max) shoulder height sitting + square root {shoulder to handtip ^ 2 - (desk depth - shelf depth + maximum body depth / 2) ^ 2} + shelf thickness
Standing posture
(Standing)
Upper limit (Max) = shoulder height standing + square root {shoulder to handtip ^ 2 - (desk depth - shelf depth + maximum body depth / 2) ^ 2} + shelf thickness

eye height means eye height. Generally, the shelves used on the desk are higher than the eye height. Therefore, the height of the eye in the sitting position is defined as the lower limit of the height of the shelf. Shoulder height sitting is the height of the shoulders in sitting position. Shoulder height is the height of the shoulder in standing posture. desk depth is the desk depth. shelf depth is the depth of the shelf. The shelf thickness is the thickness of the shelf top plate. The equations and other variables follow the above definitions.

Figure 10 is an example of an element that determines guide information about the depth and width of a shelf. The depth of the shelf is the distance from the end of the top of the shelf in the user's direction to the opposite end. The width of the shelf is the distance from the general incense end of the shelf to the opposite end in the length direction. 10 is an example of a shelf composed of a 1st shelf and a 2nd shelf. Guide information on shelf depth and width can be determined as shown in Table 5 below. Fig. 10 assumes a sitting posture.

Item Equation



1st stage shelf

B = Square root {shoulder to handtip ^ 2 - (shelf 1 height - shoulder height sitting) ^ 2}
Minimum Depth (A) = Square root {shoulder to handtip ^ 2 - (shelf1 height - shoulder height sitting) ^ 2}
- desk depth - maximum body depth / 2 + shelf 1 depth width
(reachable width 1st) = Dist (left shoulder, right shoulder) + Square root {B ^ 2 - (desk depth - maximum body depth / 2 + shelf1 depth) ^ 2}



Two-stage shelf
D = Square root {shoulder to handtip ^ 2 - (shelf 2 height - shoulder height sitting) ^ 2}
Minimum Depth (C) = Square root {shoulder to handtip ^ 2 - (shelf2 height - shoulder height sitting) ^ 2}
- desk depth - maximum body depth / 2 + shelf 2 depth width
(reachable width 2nd) = Dist (left shoulder, right shoulder) + Square root {D ^ 2 - (desk depth - maximum body depth / 2 + shelf 2 depth) ^ 2}

B means the distance that the fingertip touches the shelf of the first stage with respect to the shoulder. D means the distance that the fingertip touches the second shelf with respect to the shoulder. shelf 1 height means the height of the first stage shelf. self 1 depth means the depth of the first stage shelf. shelf 2 height means the height of the second stage shelf. self 2 depth means the depth of the second stage shelf. The remaining arithmetic expressions and variables are as described above. The depth of the shelf is determined by considering the reachable distance of the user's hand in a sitting position. The width of the shelf is determined in consideration of the reachable distance of the user's hand.

Figure 11 is an example of an element that determines guide information for a peripheral device. 11 (A) shows an example of a monitor position. The monitor position is preferably at least 30 cm away from the eye. The monitor position can be determined based on the angle between the horizontal line where the snow is located and the bottom of the monitor. As shown in Fig. 11 (A), it is most preferable that the angle of the lower end of the monitor is 30 degrees on the horizontal line basis. If the angle of the lower end of the monitor relative to the horizontal line is 45 degrees, this is an allowable range. Therefore, the monitor position can be determined based on the distance from the eyes and the line of sight in a fixed posture. 11 (B) is an example of a keyboard position. The keyboard is determined by the position of the wrist at the desk. Generally, it is preferable that the distance from the wrist rest is about 7 to 10 cm.

12 is an example of a screen to be output to the head mount display device. Fig. 12 (A) shows an Ada for a screen output from the viewpoint (first person) of the user. 12 (A) is a screen for outputting guide information on the layout of the shelf. In general, the user designates furniture as a first person view as shown in Fig. 12 (A).

Furthermore, the user can view the user who uses the designed furniture from the third person perspective. 12 (B) is a screen showing a user who uses furniture in a third person perspective. For example, if a user enters certain commands (voice commands, etc.) while designing the furniture, the screen can be switched from the first person perspective to the third person perspective. This allows the user to observe the user using the currently designed furniture. In this screen, it is also possible to output information about the posture of the user (angle of the back, etc.).

In addition, the furniture design method using the head-mounted display device as described above can be implemented as a program (or an application) including an executable algorithm that can be executed in a computer. The program may be stored and provided in a non-transitory computer readable medium.

A non-transitory readable medium is a medium that stores data for a short period of time, such as a register, cache, memory, etc., but semi-permanently stores data and is readable by the apparatus. In particular, the various applications or programs described above may be stored on non-volatile readable media such as CD, DVD, hard disk, Blu-ray disk, USB, memory card, ROM,

The present embodiment and drawings attached hereto are only a part of the technical idea included in the above-described technology, and it is easy for a person skilled in the art to easily understand the technical idea included in the description of the above- It will be appreciated that variations that may be deduced and specific embodiments are included within the scope of the foregoing description.
