Description
- This application claims priority under 35 U.S.C. §119(a) to a Korean 5 Patent Application filed in the Korean Intellectual Property Office Jan. 11, 2012 and assigned Serial No. 10-2012-0003432, the contents of which are incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates generally to a virtual space moving apparatus and method, and more particularly, to a virtual space moving apparatus and method in which a user can move as desired in a virtual space, regardless of the size of the space afforded to the user for the movement.
- 2. Description of the Related Art
- A virtual reality system has now been developed, as the need has grown for a simulator that allows a user to experience real life in Three-Dimensional (3D) virtual reality identical to an actual situation. The virtual reality system may be used to provide high reality sensation in an electronically formed environment, such as in a virtual reality game or a 3D game.
- The virtual reality system enables the user to feel sensory inputs, such as visual, auditory, and tactile senses, formed variously in a virtually created space. The sensory inputs may reproduce sensory experiences of a virtual world to provide various reality sensations.
- When the user moves in a virtual environment, the real world is maximally implemented, but it may be more convenient to experience the virtual environment than the real world. A user in the virtual reality world can move between a space and the virtual space, unlike in the real world in which movement is made continuous over time.
- For example, a virtual space apparatus including a 3D camera renders a user's 3D image output from the 3D camera into object data in a virtual space which is one-to-one size-mapped to a real space which is a user's motion space, and displays the object data on a screen. Thus, the user can move as desired in the virtual space.
- As such, when the user moves in the virtual space in the conventional art, object data corresponds to the user moves, by a user's moving distance in the real space, in the virtual space which is one-to-one mapped to the real space.
- However, due to the limited size of the real space in which the user can move, the user in the conventional art has difficulty moving as desired in the virtual space.
- Accordingly, the present invention provides a virtual space moving apparatus and method that allows a user to move as desired in a virtual space without being limited by a real space in which the user can move.
- According to an aspect of the present invention, there is provided a virtual space moving apparatus including a skeletonization unit for skeletonizing a 3D image corresponding to a subject to generate skeletal data, a skeletal data processor for generating object data corresponding to the skeletal data and mapping the object data in a virtual space, and a Graphic User Interface (GUI) for displaying the mapped object data in the virtual space, in which upon selection of an accelerated-movement mode for virtual space movement, the skeletal data processor determines motion of the subject and moves the object data in the virtual space at a movement ratio previously set corresponding to the determined motion of the subject.
- According to another aspect of the present invention, there is provided a virtual space moving method in a virtual space moving apparatus, the virtual space moving method including skeletonizing, upon input of a 3D image corresponding to a subject, the 3D image to generate skeletal data, generating object data corresponding to the skeletal data and mapping the generated object data in a virtual space, displaying the mapped object data in the virtual space, determining motion of the subject upon selection of an accelerated-movement mode for virtual space movement, and moving the object data in the virtual space at a movement ratio previously set corresponding to the determined motion of the subject.

In the following description and the accompanying drawings, well-known functions and structures will not be described for the sake of clarity and conciseness.
- In the present invention, when a user moves in a state where a sensor-recognizable region of a 3D camera and a user motion region of a real space are identical, an object in a virtual space is moved based on accelerated-movement information of an accelerated-movement region corresponding to a user's position among a plurality of accelerated-movement regions which are previously set in the sensor-recognizable region, such that the user can freely move in the virtual space without being limited by a real space.
-
FIG. 1 is a structural diagram of a virtual space moving apparatus according to an embodiment of the present invention. - Referring to
FIG. 1 , the virtual space moving apparatus includes a3D camera unit 10, askeletonization unit 20, askeletal data processor 30, and a Graphic User Interface (GUI) 40. - The
3D camera unit 10 converts a 3D image signal including 3D position information of x-axis, y-axis, and z-axis of a subject into a 3D image, and senses motion of the subject. The 3D image corresponds to the subject. The3D camera unit 10 includes a depth camera, a multi-view camera, and a stereo camera. The subject (i.e., a user) is photographed and its motion is sensed using a 3D camera, but a plurality of 2D cameras may be used or the subject motion may be determined by further including and using a motion sensor. While the virtual space moving apparatus includes the3D camera unit 10 in an embodiment of the present invention, the 3D image may be received from an external server via a wired or wireless communication unit or may have been stored in a memory embedded or inserted into the virtual space moving apparatus. - The sensor-recognizable region of the
3D camera unit 10 refers to a region that can be recognized and photographed by the3D camera unit 10, and this region is the same as a user motion region in a real space. - The
skeletonization unit 20 recognizes an outline of the subject, separates a subject region and a background region from the 3D image based on the recognized outline, and skeletonizes the subject region to generate skeletal data. Theskeletonization unit 20 outputs a plurality of optical signals to the sensor-recognizable region of the3D camera unit 10 and recognizes the outline of the subject by recognizing the optical signals received after those signals are reflected from the user. Theskeletonization unit 20 may also recognize the outline of the subject by using a pattern. - After recognizing the outline of the subject, the
skeletonization unit 20 separates the subject region and the background region from the 3D image based on the recognized outline, and skeletonizes the separated subject region to generate skeletal data (or image). In the present invention, skeletonization involves expressing an object with a fully compressed skeletal line for recognition of the object. - The
skeletal data processor 30 generates object data corresponding to the generated skeletal image and outputs the generated object data to theGUI 40. - The
skeletal data processor 30 determines whether an accelerated-movement mode for accelerated movement of mapped object data in the virtual space is selected. If the accelerated-movement mode is selected, theskeletal data processor 30 maps a plurality of previously set accelerated-movement regions around a position of the subject. If the subject's position is moved, theskeletal data processor 30 identifies an accelerated-movement region including the moved position of the subject among the plurality of previously set accelerated-movement regions. - More specifically, the
skeletal data processor 30 determines in which one of the plurality of accelerated-movement regions is included position information of skeletal data, such as x-axis, y-axis, and z-axis coordinates. Herein, respective accelerated-movement regions are set in which object motion per subject motion is made at different movement ratios. For example, if a particular accelerated-movement region is set to have object motion per subject motion which has a movement ratio of 1:2, then the object is moved in the virtual space with motion of twice the subject motion. - The
skeletal data processor 30 moves the object in the virtual space at a movement ratio previously set corresponding to the identified accelerated-movement region, and displays the moved object in the virtual space through theGUI 40, which maps and displays the object generated by theskeletal data processor 30 in the virtual space. Thegraphic user interface 40 also displays the object moved in the virtual space. - As such, the object is moved in the virtual space at a movement ratio of object motion in the virtual space corresponding to subject motion, allowing the user to move as desired in the virtual space without being limited by the real space.
-
FIG. 2 is a detailed structural diagram of theskeletal data processor 30 according to an embodiment of the present invention. - Referring to
FIG. 2 , theskeletal data processor 30 includes amotion recognizer 31, a3D image processor 32, and an accelerated-movement mode executer 33. - The motion recognizer 31 recognizes motion of a skeletal image corresponding to subject motion, which is input through the
skeletonization unit 20. For example, the motion recognizer 31 recognizes position movement of the skeletal image or a gesture such as a hand motion. More specifically, the motion recognizer 31 extracts depth information of the moving subject through the3D camera unit 10 such as a 3D camera, and segments the depth information. Thereafter, themotion recognizer 31 recognizes a 3D space position of a head, a 3D space position of a hand, and 3D space positions of torso and legs by using a structure of skeletal data regarding a human body, thus implementing interaction with 3D contents. Although user motion is recognized based on motion of the skeletal image in the embodiment ofFIG. 2 , user motion may also be recognized by a separate motion sensor. - The
3D image processor 32 generates object data corresponding to the skeletal data generated by theskeletonization unit 20, and maps the generated object data to a particular position in the virtual space. For example, the3D image processor 32 generates object data, such as a user's avatar, in the virtual space, and maps the generated avatar to a position in the virtual space corresponding to the user's position in the real space. - Thereafter, when the accelerated-movement mode is executed, the
3D image processor 32 moves the position of the object data in the virtual space at the movement ratio identified by the accelerated-movement mode executer 33 corresponding to the subject motion. - The accelerated-
movement mode executer 33 determines whether the motion recognized by themotion recognizer 31 is motion previously set for selection of the accelerated-movement mode, and executes the accelerated-movement mode or a normal mode according to a result of the determination. The normal mode is a default operation mode in the virtual space moving apparatus, in which the real space and the virtual space are one-to-one mapped and thus subject motion and object motion one-to-one correspond to each other. - More specifically, if the recognized motion is for selecting the accelerated-movement mode, the accelerated-
movement mode executer 33 maps a plurality of previously set accelerated-movement regions around the position of the skeletal data. Thereafter, if movement of the position of the skeletal data is recognized by themotion recognizer 31, the accelerated-movement mode executer 33 identifies an accelerated-movement region including the moved position information of the skeletal data among the plurality of mapped accelerated-movement regions. In this state, the accelerated-movement regions are mapped around the position of the skeletal data in the sensor-recognizable region of the3D camera unit 10. - The accelerated-
movement mode executer 33 outputs a movement ratio of object motion per user motion, which is set corresponding to the identified accelerated-movement region, to the3D image processor 32. - If the accelerated motion is not intended for selecting the accelerated-movement mode, i.e., is motion for movement in a distance, then the accelerated-
movement mode executer 33 performs a normal mode in which object motion per subject motion is made at a movement ratio of 1:1. - As such, the present invention moves the object in the virtual space at a movement ratio of object motion in the virtual space, which is previously set corresponding to user motion, allowing the user to freely move as desired without being limited by the real space.
-
FIG. 3 illustrates a process for moving in the virtual space without being limited by the real space in the virtual space moving apparatus according to an embodiment of the present invention. - Upon input of a 3D image including x-axis, y-axis, and z-axis coordinates information of the subject through the
3D camera unit 10 instep 300, theskeletonization unit 20 recognizes the outline of the subject and separates a subject region and a background region from the 3D image based on the recognized outline instep 301. Theskeletonization unit 20 outputs a plurality of optical signals to the sensor-recognizable region of the3D camera unit 10 and recognizes the optical signals received after being reflected from the subject, thus recognizing the outline of the user. - The
skeletonization unit 20 skeletonizes the separated subject region to generate skeletal data instep 302. In other words, theskeletonization unit 20, which has recognized the user's outline, separates the subject region and the background region from the 3D image based on the recognized outline, and generates the skeletal data by skeletonizing the separated subject region. - In
step 303, theskeletal data processor 30 generates object data corresponding to the generated skeletal data. - In
step 304, theskeletal data processor 30 maps the generated object data to a particular position in the virtual space and displays the generated object through theGUI 40. - In
step 305, theskeletal data processor 30 determines whether the accelerated-movement mode is selected, and if the accelerated-movement mode is selected, theskeletal data processor 30 proceeds to step 306; otherwise, theskeletal data processor 30 returns to step 300 to continuously receive a 3D image and performsteps 301 through 305. More specifically, the process of determining whether the acceleration movement mode is selected involves determining at theskeletal data processor 30 whether the accelerated-movement mode for accelerated movement of the mapped object data in the virtual space is selected. - If the accelerated-movement mode is selected, the
skeletal data processor 30 calculates position information of the skeletal data instep 306. More specifically, theskeletal data processor 30 maps the plurality of previously set accelerated-movement regions around the position of the subject, and if the position of the skeletal data is moved, theskeletal data processor 30 calculates the moved position information of the skeletal data. - In
step 307, theskeletal data processor 30 detects an accelerated-movement region including the moved position information of the subject from the plurality of previously set accelerated-movement regions. Specifically, theskeletal data processor 30 determines in which one of the plurality of accelerated-movement regions is included the position information of the skeletal data, such as x-axis, y-axis, and z-axis coordinates, in correspondence to the motion of the subject. - In
step 308, theskeletal data processor 30 moves the object in the virtual space at a movement ratio previously set corresponding to the detected accelerated-movement region, and displays the moved object in the virtual space through theGUI 40. - In
step 309, theskeletal data processor 30 determines whether the accelerated-movement mode is terminated. If the accelerated-movement mode is terminated, theskeletal data processor 30 ends the process, otherwise, theskeletal data processor 30 returns to step 306 to calculate the position information of the skeletal data and performssteps 307 through 309. - As such, the object in the embodiment of
FIG. 3 is moved in the virtual space at a previously set movement ratio of object motion in the virtual space corresponding to user motion, allowing the user to move as desired in the virtual space without being limited by the real space. -
FIGS. 4 through 8 are diagrams for describing a process for movement in the virtual space without being limited by the real space by the virtual space moving apparatus according to an embodiment of the present invention. -
FIG. 4 illustrates a process for mapping the plurality of accelerated-movement regions in the sensor-recognizable region in the accelerated-movement mode according to an embodiment of the present invention. - As shown in
FIG. 4 , assuming that a sensor-recognizable region 400 of the3D camera unit 10 is identical to a subject motion space, theskeletal data processor 30 maps a plurality of accelerated-movement regions 401 around a position of the subject in the accelerated-movement mode. -
FIG. 5 illustrates the plurality of accelerated-movement regions according to an embodiment of the present invention. - As shown in
FIG. 5 , there are five accelerated-movement regions: A1, A2, A3, A4, and A5. Although the plurality of accelerated-movement regions includes the 5 regions, it may also include n regions, where n>0. - The plurality of accelerated-movement regions may be set as shown below in Table 1.
-
TABLE 1 Accelerated- Movement Region Set Value A1 Object motion per subject motion has a movement ratio of 1:n A2 Object motion per subject motion has a movement ratio of 1:2n A3 Object motion per subject motion has a movement ratio of 1:7n A4 Object motion per subject motion has a movement ratio of 1:30n A5 Object motion per subject motion has a movement ratio of 1:100n - Referring to Table 1 and
FIGS. 6 and 7 , the accelerated-movement mode will be described in detail. -
FIG. 6 illustrates a process in which the object moves in the virtual space corresponding to user motion according to an embodiment of the present invention. - For example, when a
user 600 is situated in the accelerated-movement region A1 and moves to aposition 601, theskeletal data processor 30 may identify position information of theuser 601, that is, position information of skeletal data and determine in which one of the plurality of accelerated-movement regions the position information is included. In other words, theskeletal data processor 30 determines in which one of A1 through A4 x-axis, y-axis, and z-axis coordinates of the skeletal data are included. - Upon determining that the position of the
user 601 is included in the accelerated-movement region A3, theskeletal data processor 30 moves an object in the virtual space at a movement ratio of 1:7n for object motion per user motion as set in Table 1. -
FIG. 7 illustrates object motion in the virtual space corresponding to user motion in the real space according to an embodiment of the present invention. - For example, if the user moves at a movement ratio of 1:1 from the accelerated-movement region A1 to the accelerated-movement region A2 in the real space, the object may move at a previously set movement ratio of 1:2 in the virtual space.
-
FIG. 8 illustrates movement in the virtual space according to an embodiment of the present invention. - As the user moves a particular distance in the real space, the object in the virtual space moves from a position A to a position B, as shown in
FIG. 8 , regardless of a size or a form of the real space. -
FIGS. 9 and 10 illustrate forms of the plurality of accelerated-movement regions according to an embodiment of the present invention. - While the virtual space is implemented in a circular form in an embodiment of the present invention, it may also be configured in a form shown in
FIG. 9 and may be configured in circular, rectangular, or triangular forms as shown inFIG. 10 . - Therefore, the present invention moves the object in the virtual space at a previously set movement ratio of object motion in the virtual space corresponding to user motion, allowing the user to move as desired in the virtual space without being limited by the real space.
- Moreover, according to the present invention, an object moves an accelerated-movement distance corresponding to an accelerated-movement region previously set corresponding to user motion in a virtual space, such that a user can move anywhere as desired in the virtual space, regardless of a size of a real space.
- It can be seen that the embodiment of the present invention can be implemented with hardware, software, or a combination of hardware and software. Such arbitrary software may be stored, whether or not erasable or re-recordable, in a volatile or non-volatile storage such as a Read-Only Memory (ROM), a memory such as a Random Access Memory (RAM), a memory chip, a device, or an integrated circuit, and an optically or magnetically recordable and machine (e.g., computer)-readable storage medium such as a Compact Disc (CD), a Digital Versatile Disk (DVD), a magnetic disk, or a magnetic tape.
