Through this, the user can select a specific object in the virtual space output from the output device 150 according to his movement. The user may select a specific part to change the design from the currently output furniture object using the input device 80. Furthermore, the input device 80 may be a microphone that receives a user's voice command. In this case, the head mounted display device 100 may 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 changes the viewpoint of the screen that is output through the input command (for example, converting from the first person to the third person), changes to the output screen (such as changing the background), changes the furniture object to design, selects a specific part of the furniture object, You can start design changes for a specific part of furniture, end design changes for a specific part of furniture, and so on.

2 is an example of furniture design using a furniture design device. 2, the furniture design device includes a posture recognition device 50, a head mounted display device 100, and an input device 80. When a user's gesture is an input command, a separate physical input device 80 may not be used.

In FIG. 2, the dotted square area 200 shows an example of a screen output by the head mounted display device 100. The head mounted display device 100 basically outputs a furniture object, which is a design target, on a screen. Various furniture can be designed, but the desk is shown as an example.

The head mounted display device 100 may output other objects in addition to furniture objects on the screen. For example, the head mounted display device 100 may output a screen identical to a place where actual furniture is to be placed on the screen. The head mounted display device 100 may output structures such as walls and columns constituting a building. In addition, the head-mounted display device 100 may output other furniture that has already been placed indoors. For example, if a desk is designed, the head mounted display device 100 may output a bookshelf, a chest of drawers, etc., which are already placed in the study room where the desk is to be placed. Through this, the user can design the furniture in consideration of the space where the actual furniture will be placed. The head mounted display device 100 previously holds data on a space, background, furniture object, and the like output on the screen, and configures and outputs the screen based on the data.

Furniture objects consist of a plurality of parts. The desk shown in Fig. 2 will be described as an example. The furniture object shown in FIG. 2 is composed of a desk body and a shelf placed on the desk body. The desk body may be defined by a plurality of parts constituting the desk and the size or 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 (leg part) of the desk and the other side. The depth of the desk (indicated by ③) means the length between the front side (face facing the user) and the back side of the desk. The height of the foot rest (indicated by ④) means the length from the bottom surface to the footrest.

The shelf has two stages. The height of the first stage shelf (indicated by ⑤) means the length from the bottom surface to the bottom of the first stage shelf. In some cases, unlike FIG. 2, the height of the first stage shelf may be a length from the top of the desk to the bottom of the first stage shelf. The height of the first stage shelf (indicated by ⑥) means the length from the bottom surface to the bottom of the second stage shelf. The height of the entire shelf (indicated by ⑦) means the length from the bottom surface to the top surface of the shelf (in FIG. 2, the top surface of the second-stage shelf). Although not shown in FIG. 2, the depth of the shelf, the spacing of the partitions that divide the shelf regularly, and the like may also 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 may select at least one part of a plurality of parts constituting the furniture object, and change the layout of the selected part. Here, the layout is determined by at least one element of one-way length, width, depth, size, and position of a specific region.

3 (A) is an example in which the length of a desk is changed. 3 (A) is an example of extending the right side of the desk. The dotted line in FIG. 3 (A) shows the site before the change. For example, the user can adjust the length of the desk by selecting the right side of the desk, holding the right side in the selected state, and stretching or reducing it. Alternatively, the user may select a site to be changed, and input the length of the site to change the layout of the site. 3 (B) is an example in which the height of the desk is changed. The dotted line in FIG. 3 (B) represents the extended height. For example, the user can change the height of the desk by selecting the top surface of the desk and adjusting the height of the top surface. 3 (C) is an example in which the height of the first-stage shelf is changed. In FIG. 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 by selecting the top surface of the first-stage shelf and increasing or decreasing the top plate surface. 3 (D) is an example in which the depth of the desk is changed. The dotted line in FIG. 3 (D) represents the depth of the stretched 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.

There are various ways in which a user changes the layout of a specific part of a furniture object. (1) First, the user must select a specific part of the furniture object output to the head mounted display device 100. The head mounted display device 100 may output an object capable of selecting a specific portion 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 on the screen to implement a state of contacting a specific area according to a user's motion. (i) The user can select a specific part through a specific gesture. (ii) The user may select a corresponding part using a separate physical input device while in contact with a specific part on the screen. (iii) The user may select a corresponding part by voice input while in contact with a specific part on the screen. (2) After that, the user can change the layout of the selected site. (i) The user can change the layout by selecting a specific part and changing the position or size of the part. For example, the user may 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 site, the user can change the layout by entering information corresponding to the size or location of the site. 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 site. (iii) After selecting a specific site, the user can change the layout of the site by selecting one of the layout samples (example) on the screen.

The head mounted display device 100 outputs information (guide information) that is helpful in designing furniture objects on a screen for designing furniture objects. The head mounted display device 100 may recommend a layout for a specific part of a furniture object. For example, the head mounted display device 100 may recommend at least one of length, height, width, and depth of a specific area. In addition, the head mounted display device 100 may recommend the location 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, etc. may be recommended. Guide information may be determined based on posture information of a person recognized by the posture recognition device 50. The head mounted display device 100 outputs customized guide information according to a user's body characteristics (body shape) or posture characteristics. This allows users to conveniently design ergonomic furniture. The head mounted display device 100 may output a desired location or a placeable area of a specific region as guide information.

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

In FIG. 4, the types of items to be considered in determining guide information are illustrated 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 body posture, body activity, body clearance and body reachability. Each item is related to each other and may also mean functionally redundant content. Body posture is related to the user's desired posture. Physical activity is an item that considers the location or motion of a user's body part using furniture. The free body space means free space for a user's body part using furniture. Body accessibility is an item that considers the reach of the user's body using furniture. The convenience of using objects is an item that considers other objects used with furniture. The free space is an item indicating the free space associated with the furniture itself.

In FIG. 4, guide information indicates a kind of guide information. 4 is an item considering a desk, and guide information different from FIG. 4 may be used according to the type of furniture object. An example of determining some guide information in FIGS. 6 to 12 will be described.

In FIG. 4, the guide information variable means a variable to be considered in determining guide information. In FIG. 4, items separated by italics are static variables, and items denoted by underlines are dynamic variables. The dynamic variable can be changed in real time according to the user's posture and the design of the furniture object. The head mounted display device 100 determines guide information in consideration of a static variable and a dynamic variable changed in real time, and outputs the most appropriate guide information to the screen.

Guide information may be determined by using generally known ergonomic information in addition to the information shown in FIG. 4.

5 is 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. In FIG. 5, a square area is an example of a screen displayed on a screen, and a red arrow is additionally displayed to describe guide information output from the screen.

5A is an example of outputting guide information related to body posture. 5 (A) shows the angle of the back and the elbow of the user using the desk in the third person view. The angle is expressed in the form of a constant gauge. The gauge is divided into red and green areas, with red representing an inappropriate angle and green representing a desirable angle. Through this, the user can determine whether his current posture is a desirable posture. As described above, guide information is changed according to dynamic variables. Therefore, the user can check whether his current posture is in a desirable state and design furniture based on the preferred posture.

5B is an example of outputting guide information related to physical activity. 5 (B) is guide information on the height of the desk. The position of the desk top plate is displayed on the screen in a certain area. Guide information can be displayed in various ways. 5 (B), the height of the desk in the standing position is represented by a dotted red area.

5 (C) is an example of outputting guide information related to physical activity. 5 (C) is an example of recommending the height (position) of the monitor corresponding to another object to be used for the desk. The height of the monitor is related to the height of the user's eyes. The head mounted display device 100 may output guide information on the monitor height based on the posture of the user sitting on the chair. Fig. 5 (C) shows the preferred position of the monitor as a dotted area. Furthermore, a monitor arranged at a specific location may be displayed on the screen.

5 (D) is an example of outputting guide information related to physical accessibility. 5 (D) is an example of recommending the height of the shelf. The head mounted display device 100 may output guide information about the height of the shelf based on the area where the arm can reach according to the current user's posture information. 5 (D) shows the location of the shelf on the preferred screen as a dashed area. The upper dotted line corresponds to the upper limit line considering the reachability, and the lower dotted line corresponds to the lower limit line considering the structure of the shelf or the posture of the user.

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

5 (F) is an example of outputting guide information related to the free space. When a chair is used together with a desk, the head mounted display device 100 may output the appropriate chair position as guide information in consideration of the desk position. 5 (F) is an example in which a limit line in which a chair can be arranged on the floor surface is displayed.

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

Item Equation

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

seat height means the height of the chair and is defined as the length from the floor to the top of the chair. The thigh clearance means the thickness of the user's thigh. Table top thickness means the thickness of the desk top. The elbow rest height is defined as the height of the elbow in the sitting position from the top of the chair to the elbow. elbow height is defined as the height of the elbow in the standing position from the floor to the elbow. The elbow end to pivot length means the length from the bottom of the elbow to the center of rotation. As a result, "seat height + elbow rest height + elbow end to pivot length" or "elbow height + elbow end to pivot length" indicates the distance from the floor surface to the elbow rotation joint in the current user's posture. elbow to wrist length indicates the distance from the tip of the elbow to the wrist. The upper limit angle of the elbow rotation for typing based on the vertical line is 70 degrees, and the lower limit angle is 100 degrees.

7 is an example of an element for determining guide information for a desk width. The desk width is defined as the distance from one end of the desk top to the other in the lengthwise direction of the desk. Guide information on the desk width may be determined as shown in Table 2 below.

Item Equation Physical limitations
(Physical Restriction) = elbow to elbow breadth Main business scope
(Primary work zone) = radius of elbow pivot to handtip length (0-135 degrees) Extended business scope
(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). Define the minimum width of the desk as the distance (width) between the two elbows. The elbow pivot is the center of rotation of the elbow. The elbow pivot to handtip length is the distance from the elbow rotation center to the handtip. The main scope of work corresponds to the radius at which the fingertip can rotate based on the center of rotation of the elbow. The main scope of work was limited to 0-135 degrees (45 degrees on a vertical line) considering the rotation angle of the elbow. The extended scope of work corresponds to the radius at which the fingertip can rotate around the shoulder. In FIG. 7, the main business scope of the left hand is indicated in orange, and the main business scope of the right hand is indicated in light green. In addition, the extended scope of work for each hand is indicated in yellow. As such, the width of the desk may be determined according to the area of the work scope. That is, the width of the desk may be determined according to the reachable range of the user's body (hand).

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

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

The physical lower limit of the desk depth may be determined by considering the sitting position. The buttock-knee length is the distance from the tip of the hip to the murub. The maximum body depth means the longest of the horizontal distances between the upper and lower surfaces 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 the calf to the toe. In the end, the lower limit corresponds to the distance that the toes reach from the front of the body while the person is as close to the desk as possible in a general posture.

The upper limit of the desk depth can be determined by considering the standing posture. Shoulder to spine refers to the distance from the shoulder to the spine. shoulder to handtip means the distance from the shoulder to the fingertip. The spine height is the distance from the bottom surface to the spine. In the formula, 'Square root' is the formula to find the square root, and '^ 2' means the square operation.

9 is an example of an element for determining guide information for a shelf height. The height of the turn is defined as the distance from the bottom to the top of the shelf. 9 (A) is an example of determining a shelf height in a sitting position. 9 (B) is an example of determining the shelf height in a standing position. Guide information on the shelf height can be determined as shown in Table 4 below.

Item Equation Sitting position
(Sitting) Lower limit = 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. The shelves used for desks are usually higher than the eye level. Therefore, the eye height in a sitting position is defined as the lower limit of the shelf height. shoulder height sitting is the height of the shoulder in a sitting position. shoulder height standing is the height of the shoulder in a standing position. desk depth is the desk depth. shelf depth is the depth of the shelf. shelf thickness is the thickness of the shelf top. The arithmetic expression and other variables follow the above definition.

10 is an example of an element for determining guide information on the depth and width of a shelf. The depth of the shelf is the distance from the end of the shelf top in the user direction to the opposite end. The width of the shelf is the distance from the lengthwise end of the shelf to the opposite end of the shelf. 10 is an example of a shelf composed of a 1st shelf (1st Shelf) and a 2nd shelf (2nd Shelf). Guide information on shelf depth and width can be determined as shown in Table 5 below. 10 assumes a sitting position.

Item Equation



1-tier shelf

B = Square root {shoulder to handtip ^ 2-(shelf 1 height-shoulder height sitting) ^ 2}
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}



2-stage shelf
D = Square root {shoulder to handtip ^ 2-(shelf 2 height-shoulder height sitting) ^ 2}
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 refers to the distance that the fingertip touches the first shelf with respect to the shoulder. D is the distance that the fingertip touches the 2nd shelf relative to the shoulder. shelf 1 height means the height of the 1st shelf. self 1 depth means the depth of the first stage shelf. shelf 2 height means the height of the 2nd shelf. self 2 depth means the depth of the 2-stage shelf. The remaining arithmetic expressions or variables follow the above description. The depth of the shelf is determined by considering the distance that the user's hand can reach in a sitting position. The width of the shelf is determined taking into account the distance the user's hand can reach.

11 is an example of an element for determining guide information for a peripheral device. 11 (A) is an example of a monitor position. Preferably, the monitor position is at least 30 cm away from the eyes. The monitor position may be determined based on the horizontal line where the eye is located and the angle of the bottom of the monitor. As shown in FIG. 11 (A), it is most preferable if the angle of the bottom of the monitor is 30 degrees based on the horizontal line. If the angle of the bottom of the monitor is 45 degrees based on the horizontal line, it is an allowable range. Therefore, the monitor position can be determined based on the distance from the eye and the gaze range in a fixed posture. 11 (B) is an example of a keyboard position. The keyboard is determined by the position of the wrist on the desk. In general, it is desirable to fall about 7 to 10 cm from the support rest of the timber (Wrist rest).

12 is an example of a screen output to a head mounted display device. 12 (A) is a view of a screen output from the user's gaze point of view (first person). 12 (A) is a screen for outputting guide information for the layout of the shelf. In general, the user designs the furniture in the first person view as shown in FIG. 12 (A).

Furthermore, the user can look at the user who uses the designed furniture from a third person perspective. 12 (B) is a screen showing a user who uses furniture from a third person perspective. For example, if a user inputs a certain command (voice command, etc.) while designing furniture, the screen may be switched from a first person perspective to a third person perspective. This allows the user to observe the user using the currently designed furniture. On this screen, information about the user's posture (such as the angle of the back) may be output.

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

The non-transitory readable medium means a medium that stores data semi-permanently and that can be read by a device, rather than a medium that stores data for a short time, such as registers, caches, and memory. Specifically, the various applications or programs described above may be stored and provided in a non-transitory readable medium such as a CD, DVD, hard disk, Blu-ray disk, USB, memory card, ROM, and the like.
