Description

Technical Field

[0001] The present invention relates to a content production device, and more specifically, to a fitness content production device using sprites defined for body parts.

Background Art

[0002] The content described in this section only provides background information related to an embodiment of the present invention and does not constitute the prior art.

[0003] Ordinary fitness involves exercising using equipment, so there is a risk of injury due to incorrect exercise. Also, since the exercises that can be performed using specialized equipment are limited, there is a problem that anaerobicity is likely to occur. Furthermore, equipment such as treadmills for aerobic exercise has a monotonous exercise process and only repeats a predetermined course, so there is a problem that users often give up on exercise halfway.

[0004] In order to solve such conventional problems, there has been developed an extended reality interactive sports device that can perform various exercises with only the body without using separate objects or wearing equipment indoors (see, for example, Korean Patent No. 10-2233395 (Title of Invention: Extended Reality Interactive Sports Device Using Rider Sensor, Registration Date: March 23, 2021), Korean Patent No. 10-2430084 (Title of Invention: Extended Reality Interactive Sports System Using Rider Sensor, Registration Date: August 2, 2022), etc.).

[0005] Such augmented reality interactive sports devices project images for content onto the floor and track the motion of users using sports content with LiDAR sensors to control the interaction between the sports content and the user. This allows users to enjoy sports indoors using only their bodies, without the need for additional objects or devices. Furthermore, the wide range of motion tracking allows for efficient use of the floor surface. In addition, by tracking the user's motion using two LiDAR sensors, it is possible to quickly and accurately track the motion of each user even when multiple users are using sports content simultaneously.

[0006] Such augmented reality interactive sports devices require continuous content development, as the more diverse the content, the more it can stimulate interest in exercise and train various parts of the body.

[0022] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that they can be easily implemented by a person with ordinary skill in the art to which the present invention pertains. However, the present invention can be realized in a variety of different forms and is not limited to the embodiments described herein. In the drawings, parts that are not relevant to the description have been omitted in order to clearly illustrate the present invention, and similar parts throughout the specification are denoted by similar reference numerals.

[0023] Throughout this specification, when a part is described as being “connected” to another part, this includes not only cases where they are “directly connected” but also cases where they are “indirectly connected” through another element in between. Furthermore, when a part is described as “containing” a component, this should be understood, unless otherwise stated, as not excluding other components but rather meaning that other components may be included, and not presupposing the possibility of the presence or addition of one or more other features, figures, steps, actions, components, parts, or combinations thereof.

[0024] The following embodiments are detailed descriptions to aid in understanding the present invention and do not limit the scope of the present invention. Therefore, inventions of the same scope that perform the same function as the present invention would also fall within the scope of the present invention.

[0025] Furthermore, the various configurations, processes, steps, or methods included in each embodiment of the present invention can be shared to the extent that they are not technically contradictory to one another.

[0026] Figure 1 shows the configuration of a fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention. As shown in Figure 1, the fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention is a content creation device 200 that creates fitness content to be played on an augmented reality interactive sports device 100 that projects images onto the floor and tracks the user's motion to control the interaction between the content and the user. The device 200 can be configured to include a sprite storage unit 210, a content editing unit 230, and a content creation unit 240, and can further include an effect storage unit 220. The fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention can communicate with the augmented reality interactive sports device 100 by wire or wireless means so that the created fitness content can be played on the augmented reality interactive sports device 100.

[0027] Figure 2 shows an augmented reality interactive sports device 100 used in a fitness content creation device 200 that uses sprites defined for body parts according to one embodiment of the present invention. As shown in Figure 2, the augmented reality interactive sports device 100 can be configured to include a main body 110, a projector unit 120 provided on the front of the main body 110 for projecting images for fitness content onto the floor, lidar sensor units 130a and 130b mounted facing the projection direction of the projector unit 120, a motion tracking unit (not shown) that uses the lidar sensor units 130a and 130b to recognize the user's position according to the fitness content and track the user's motion, a sensor connecting unit 150 with one end connected to the side of the lower end of the main body 110 and the other end connected to the lidar sensor units 130a and 130b so that the lidar sensor units 130a and 130b are separated from the main body 110 by a predetermined distance, and a control unit (not shown) that outputs fitness content via the projector unit 120 to provide the user with fitness content based on augmented reality and controls the interaction between the fitness content and the user using the user's motion tracked by the motion tracking unit (not shown). Furthermore, the system can also include a display unit 180 located on the front of the main unit 110, which receives input signals for selecting fitness content and outputs play information related to the fitness content, and a speaker unit 190 that outputs sounds related to the fitness content.

[0028] Here, the LiDAR sensor units 130a and 130b include two or more LiDAR sensors connected to both sides of the lower end of the main body 110 via the sensor connecting unit 150, thereby avoiding tracking failures in the laser scanning shade area due to the relative positions of multiple users and enabling the system to determine the position of each user. Furthermore, the motion tracking unit 140 uses the LiDAR sensor units 130a and 130b to laser scan a plane at a predetermined height from the ground (approximately 1 to 7 cm above the floor surface) to recognize the position of body parts in contact with the floor surface, and tracks the changes in the position of the user's body parts to track the user's motion.

[0029] Details of the augmented reality interactive sports device 100 can be constructed by referring to Korean Patent No. 10-2233395 (Title of Invention: Augmented Reality Interactive Sports Device 100 Using a LiDAR Sensor, Registration Date: March 23, 2021), Korean Patent No. 10-2430084 (Title of Invention: Augmented Reality Interactive Sports System Using a LiDAR Sensor, Registration Date: August 2, 2022), etc.

[0030] In the following, with reference to Figures 1 and 2, the various components of a fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention will be described in detail.

[0031] The sprite storage unit 210 can store sprites defined for body parts such as feet, hands, arms, and buttocks. More specifically, the sprite storage unit 210 stores sprites with defined shapes and sizes, but it can also store sprites that are defined as different shapes depending on the body part. Here, a sprite is a two-dimensional graphic or object composited into a video using computer graphics, and is an object that can move independently of the background. The sprite storage unit 210 allows users to intuitively distinguish each sprite and understand how to execute the content using sprites with predefined shapes according to the body part.

[0032] Figure 3 shows sprites used in a fitness content creation device 200 that uses sprites defined for body parts according to one embodiment of the present invention. As shown in Figure 3, the sprite storage unit 210 of the fitness content creation device 200 that uses sprites defined for body parts according to one embodiment of the present invention can store a square sprite defined for the feet, a circular sprite defined for the hands, an elliptical sprite defined for the arms, and a hexagonal sprite defined for the buttocks. The augmented reality interactive sports device 100 shown in Figure 2 performs exercise movements on the floor using fitness content projected onto the floor, and basically the movements can be performed by touching the floor surface with four body parts: hands, feet, arms, and buttocks. In this invention, by representing the body parts that are touched on the floor surface during exercise movements with different shapes, the user can intuitively grasp the way to play the fitness content without further explanation and perform exercise movements by touching the sprites with the body parts corresponding to each shape.

[0033] Thus, in the fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention, new exercises can be easily created by combining sprites defined for body parts such as feet, hands, arms, and buttocks, which are stored in the sprite storage unit 210. Users of the created fitness content can then perform the exercises intuitively without the need for a coach's explanation.

[0034] The effect storage unit 220 can store effects that can be applied to sprites. Here, an effect is an element that is applied to a sprite when an event occurs, such as when the sprite is touched by the user's body, and can include things like color changes, shape additions, and animations of the sprite. For example, when an event occurs on a sprite, the sprite may change color, blink, have a shape like the edge of the sprite added and gradually increase in size, have a band of a specific color rotate along the edge of a stripe, or have an image like fireworks of a different color from the stripe added. By applying such effects to a sprite, the interaction between the user and the fitness content can be consistently expressed, and the user can visually confirm the results of their exercise.

[0035] The content editing unit 230 can load sprites stored in the sprite storage unit 210 based on user input and arrange at least one sprite in combination. Here, the user can place the sprites defined for each body part—feet, hands, arms, and buttocks—at positions where those body parts must be in contact with the floor, as shown in Figure 3, depending on the exercise motion of the fitness content they intend to create.

[0036] More specifically, the content editing unit 230 can, in response to user operations, load effects stored in the effect storage unit 220 and add at least one of those effects to a sprite. That is, it can add and set effects that are applied to a sprite when an event occurs, such as when a user's body part comes into contact with the placed sprite. At this time, multiple effects may be added to a sprite, and different effects may be added depending on the type of event. For example, different effects can be added to a sprite touch event and a movement completion event. In other words, a user editing and creating fitness content can edit the fitness content by placing sprites and adding effects to them via the content editing unit 230.

[0037] The content creation unit 240 can create fitness content in response to operations performed by the content editing unit 230, such that the placed sprites indicate the parts of the user's body that must come into contact with the floor and their positions. The content creation unit 240 can create fitness content such that when an event is generated on a sprite based on the user's body position tracked by the augmented reality interactive sports device 100, the effects added to the sprite where the event occurred are applied. In other words, the content creation unit 240 can create fitness content from the content edited by the content editing unit 230.

[0038] The augmented reality interactive sports device 100 can track the user's motion using the LiDAR sensor units 130a and 130b and determine when an event has occurred. For example, in fitness content, an event can be determined to have occurred when the position or area of ​​a sprite projected onto the floor corresponds to the position of a detected body part such as a foot or hand. More specifically, an event can be determined to have occurred when the area of ​​the sprite projected onto the floor overlaps with at least a portion of the detected body part area, or when a specific position of the sprite corresponds to the area of ​​the detected body part, or when a predetermined percentage or more of the body part area overlaps with the area of ​​the sprite.

[0039] Figure 4 shows an example of lunge content created via a fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention. As shown in Figure 4, lunge content can be created using the fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention, and the created lunge content can be projected onto the floor surface via an augmented reality interactive sports device 100. That is, a screen like the first image in Figure 4 can be projected onto the floor surface, where four square sprites defined for the feet ("foot sprites") are arranged. By making two of the foot sprites blue to differentiate their colors, the user can easily identify the sprite where their current foot should be positioned. As shown in Figure 4, a lunge can be performed by standing on the lower foot sprite and alternately stepping on the upper and lower foot sprites with the left and right feet. At this time, by changing the color of the foot sprite where the user's foot should be positioned for the lunge, or by making it blink (in Figure 4, it is blinking in blue), the user can easily perform the lunge. When a predetermined amount of time has elapsed while in a lunge position, the count is reset to one lunge, a red fireworks-like effect is applied, and the color of the foot sprite changes and it flashes to indicate the lunge on the opposite side. The user can then move their left and right feet to the corresponding sprites to perform the lunge.

[0040] Figure 5 shows an example of squat content created via a fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention. As shown in Figure 5, squat content can be created with the fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention, and a screen like the first image in Figure 5 can be projected onto the floor surface via the augmented reality interactive sports device 100. Here, two square foot sprites and one circular hand sprite can be placed at the vertices of an isosceles triangle with the two foot sprites as the base. The user can perform a squat by standing on the foot sprites, keeping their back straight, slowly lowering their hips, and touching the circular hand sprite. As shown in the fourth image in Figure 5, a red fireworks-like effect can be applied when an event occurs due to touching the hand sprite.

[0041] Figure 6 shows an example of plank content created via a fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention. As shown in Figure 6, plank content can be created with the fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention, and a screen like the first image in Figure 6 can be projected onto the floor surface via an augmented reality interactive sports device 100. Here, two square foot sprites and two elliptical arm sprites placed side by side at a certain distance apart from the two foot sprites can be combined and arranged. The user can perform a plank movement by standing on the foot sprites, lifting their knees and pelvis, and simultaneously pressing their elbows and fists against the arm sprites. When a touch event corresponding to the plank movement occurs on the foot sprites and arm sprites, an effect that changes the color of the sprites is applied, allowing the user to easily see the interaction results corresponding to the fitness movement. This plank posture can be maintained for a predetermined time.

[0042] Figure 7 shows an example of arm walking content created via a fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention. As shown in Figure 7, arm walking content can be created with the fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention, and a screen like the first image in Figure 7 can be projected onto the floor surface via an augmented reality interactive sports device 100. Here, two square foot sprites, four circular hand sprites, and two elliptical arm sprites are combined and arranged in the order of legs, hands, hands, and arms. The user can perform an arm walking motion by standing on the foot sprites with their feet fixed, touching the hand sprites one by one with their hands to move to the arm sprites, stretching their body and lying face down, and then performing the reverse motion, touching the hand sprites one by one to move their hands near their feet and stand up. At this time, the sprites change color to indicate the next touch point, allowing the user to perform the motion easily and accurately.

[0043] Figure 8 shows an example of a fitness content list created via a fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention. As shown in Figure 8, the fitness content creation device 200 using sprites defined for body parts according to one embodiment of the present invention can realize various fitness content in addition to lunges, squats, planks, and arm walking using sprites defined for body parts such as feet, hands, arms, and buttocks. Since the sprite shapes are predefined, users can easily create new fitness content by utilizing sprites corresponding to the body parts that should come into contact with the floor surface according to each fitness movement.

[0044] As described above, according to the fitness content creation device 200 proposed in the present invention, which uses sprites defined for body parts, new fitness content can be easily created by combining and arranging sprites defined for body parts such as feet, hands, arms, and buttocks, so that the sprites indicate the body parts of the user that must come into contact with the floor surface according to the exercise movements of the fitness content, and the position of those body parts. Therefore, users using the created fitness content can perform exercises intuitively without explanation from a coach. Furthermore, according to the present invention, by adding effects applicable to sprites to sprites and applying the added effects to the sprites when events occur, the interaction between the user and the fitness content can be consistently expressed, thereby allowing the user to visually confirm the results of their exercise movements.

[0045] On the other hand, the present invention may include a computer-readable medium containing program instructions for performing operations implemented in various communication terminals. For example, the computer-readable medium may include magnetic media such as hard disks, floppy disks, and magnetic tapes; optical media such as CD-ROMs and DVDs; magneto-optical media such as floptical disks; and hardware devices such as ROMs, RAMs, and flash memory that are specially configured to store and execute program instructions.

[0046] Such computer-readable media may include program instructions, data files, data structures, etc., either individually or in combination. In this case, the program instructions recorded on the computer-readable media may be specifically designed and configured to realize the present invention, or they may be publicly known and usable by those skilled in the art of computer software. For example, they may include not only machine code generated by a compiler, but also high-level language code that can be executed by a computer using an interpreter or the like.
