DETAILED DESCRIPTION
Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. Embodiments are described below to explain the present disclosure by referring to the figures.
FIG. 1 illustrates an overall system configuration according to an embodiment.
Referring to FIG. 1, an apparatus for controlling a vibration transfer 100 may provide a user with a sense of movement of a virtual vibration body 130 by controlling a first vibration device 110 and a second vibration device 120. In this instance, the first vibration device 110 and the second vibration device 120 may correspond to devices generating a vibration, and may change at least one of a vibration magnitude, a frequency, a vibration acceleration, and a vibration timing according to a vibration value determined by the apparatus for controlling a vibration transfer 100.
In this instance, the virtual vibration body 130 may correspond to a vibration source of a vibration provided to a user using the first vibration device 110 and the second vibration device 120. In particular, the virtual vibration body 130 may correspond to a virtual vibration body, a virtual object in a virtual reality, and content manipulated by a user.
For example, when a user generates a vibration flow moving from a left hand to a right hand by shaking the left hand to a right hand side while holding the first vibration device 110 and the second vibration device 120 in both hands, the apparatus for controlling a vibration transfer 100 may determine that the virtual vibration body 130 corresponding to a vibration source moves from the left hand to the right hand, and provide the user with a sense of movement of the virtual vibration body 130 from the left hand to the right hand by controlling the first vibration device 110 and the second vibration device 120. In particular, the apparatus for controlling a vibration transfer 100 may provide the user with a sense of movement of the virtual vibration body 130 from the left hand to the right hand by decreasing a vibration of the first vibration device 110 held by the user in the left hand since a distance to the virtual vibration body 130 increases over time, and increasing a vibration of the second vibration device 120 held by the user in the right hand since a distance to the virtual vibration body 130 decreases over time.
When the user manipulates content using an interface, the apparatus for controlling a vibration transfer 100 may allow the user to sense, through a vibration, a movement of the content by controlling the first vibration device 110 and the second vibration device 120 according to the movement of the content.
When the virtual vibration body 130 is in a stationary state between the first vibration device 110 and the second vibration device 120, the apparatus for controlling a vibration transfer 100 may cause the virtual vibration body 130 to infinitesimally shuttle in a direction of either the first vibration device 110 or the second vibration device 120, thereby providing a user with a sensation that the virtual vibration body 130 is placed between the first vibration device 110 and the second vibration device 120.
FIG. 2 illustrates a detailed configuration of an apparatus for controlling a vibration transfer according to an embodiment.
Referring to FIG. 2, the apparatus for controlling a vibration transfer 100 may include a location identification unit (location identifier) 210, a virtual vibration body controller 220, a vibration value determining unit (vibration value determiner) 230, and a vibration device controller 240.
The location identification unit 210 may identify a location of a virtual vibration body, a direction of a movement of the virtual vibration body, and a location of vibration devices.
The virtual vibration body controller 220 may control a virtual vibration body located between vibration devices placed in a first area and vibration devices placed in a second area located opposite the first area. In particular, when a virtual vibration body is located between vibration devices, the virtual vibration body controller 220 may classify, based on the virtual vibration body, vibration devices into the vibration devices placed in the first area and the vibration devices placed in the second area located opposite to the first area, and periodically shuttle the virtual vibration body between the first area and the second area. An operation of the virtual vibration body controller 220 will be further described with reference to FIGS. 6 and 16.
The vibration value determining unit 230 may determine vibration values of vibration devices according to a direction of a movement of a virtual vibration body corresponding to a vibration source. In this instance, when the virtual vibration body controller 220 controls the virtual vibration body, the vibration value determining unit 230 may determine, based on a control of the virtual vibration body by the virtual vibration body controller 220, vibration values of the vibration devices placed in the first area and vibration values of the vibration devices placed in the second area.
In this instance, the vibration value determining unit 230 may determine vibration values of vibration devices corresponding to the direction of the movement of the virtual vibration body, and vibration values of vibration devices corresponding to a direction opposite to the direction of the movement of the virtual vibration body. Here, the direction of the movement of the virtual vibration body may correspond to a direction in which the virtual vibration body approaches, and the direction opposite to the direction of the movement may correspond to a direction in which the virtual vibration body moves away.
For example, the vibration value determining unit 230 may increase a vibration magnitude among vibration values of vibration devices corresponding to the direction of the movement of the virtual vibration body, and decrease a vibration magnitude among vibration values of vibration devices corresponding to the direction opposite to the direction of the movement.
The vibration value determining unit 230 may increase an amplitude of a frequency among vibration values of the vibration devices corresponding to the direction of the movement of the virtual vibration body, and decrease an amplitude of a frequency among vibration values of the vibration devices corresponding to the direction opposite to the direction of the movement.
The vibration value determining unit 230 may increase a vibration acceleration among vibration values of the vibration devices corresponding to the direction of the movement of the virtual vibration body, and decrease a vibration acceleration among vibration values of the vibration devices corresponding to the direction opposite to the direction of the movement of the virtual vibration body.
The vibration value determining unit 230 may decrease a vibration timing interval among vibration values of the vibration devices corresponding to the direction of the movement of the virtual vibration body, and increase a vibration timing interval among vibration values of the vibration devices corresponding to the a direction opposite to the direction of the movement of the virtual vibration body.
The vibration value determining unit 230 may determine, based on a velocity of movement of the virtual vibration body, variation velocities of vibration values of the vibration devices corresponding to the direction of the movement of the virtual vibration body and vibration values of the vibration devices corresponding to the direction opposite to the direction of the movement of the virtual vibration body.
For example, when the user rapidly moves the virtual vibration body 130, vibration values of the vibration devices corresponding to the direction of the movement of the virtual vibration body may rapidly increase over time, and vibration values of the vibration devices corresponding to the direction opposite to the direction of the movement of the virtual vibration body may rapidly decrease. When the user slowly moves the virtual vibration body 130, vibration values of the vibration devices corresponding to the direction of the movement of the virtual vibration body may slowly increase over time, and vibration values of the vibration devices corresponding to the direction opposite to the direction of the movement of the virtual vibration body may slowly decrease.
The vibration device controller 240 may control a plurality of vibration devices according to a vibration value determined by the vibration value determining unit 230.
FIG. 3 illustrates an example of a method of controlling a vibration transfer according to an embodiment.
Referring to FIG. 3, a method of controlling a vibration transfer according to an embodiment may correspond to a method of controlling a first vibration device 110 and a second vibration device 120 by an apparatus for controlling a vibration transfer 100 when a virtual vibration body 130 corresponding to a vibration source moves from the first vibration device 110 held by a user in a left hand 310 to the second vibration device 120 held by the user in a right hand 320, as illustrated by arrow 330.
First, when the virtual vibration body 130 is placed relatively close to the first vibration device 110, the apparatus for controlling a vibration transfer 100 may determine a vibration value of the first vibration device 110 to be greater than a vibration value of the second vibration device 120, thereby providing a user with a sensation that the virtual vibration body 130 is placed relatively close to the left hand 310.
Subsequently, when the virtual vibration body 130 moves toward the second vibration device 120 by user manipulation or an application, the apparatus for controlling a vibration transfer 100 may decrease the vibration value of the first vibration device 110, and increase the vibration value of the second vibration device 120, thereby providing a user with a sensation that the virtual vibration body 130 moves from the left hand 310 to the right hand 320.
When the virtual vibration body 130 moves relatively close to the second vibration device 120, the apparatus for controlling a vibration transfer 100 may determine the vibration value of the second vibration device 120 to be greater than the vibration value of the first vibration device 110, thereby providing a user with a sensation that the virtual vibration body 130 is placed relatively close to the right hand 320.
A variation of a vibration value according to a movement of the virtual vibration body 130 will be described with reference to FIGS. 4 and 5.
That is, the apparatus for controlling a vibration transfer 100 according to an embodiment may provide a user with a sensation that the virtual vibration body 130 moves from a location around the left hand 310 to a location around the right hand 320 by changing vibration values of the first vibration device 110 and the second vibration device 120 according to a location of the virtual vibration body 130.
FIG. 4 illustrates an example of a method of transferring a vibration using a vibration frequency according to an embodiment.
Referring to FIG. 4, when the virtual vibration body 130 is placed relatively close to the first vibration device 110, the apparatus for controlling a vibration transfer 100 may determine a vibration frequency 410 of the second vibration device 120 and a vibration frequency 420 of the first vibration device 110.
In this instance, since the second vibration device 120 vibrates at the vibration frequency 410 less than the vibration frequency 420 of the first vibration device 110, a user may sense that the virtual vibration body 130 is placed around the first vibration device 110 that vibrates relatively frequently.
Subsequently, when the virtual vibration body 130 moves by a manipulation of a user or an application to be placed between the first vibration device 110 and the second vibration device 120, the apparatus for controlling a vibration transfer 100 may determine a vibration frequency 411 of the second vibration device 120 and a vibration frequency 421 of the first vibration device 110 to be equal to each other as illustrated in FIG. 4.
In this instance, since the first vibration device 110 and the second vibration device 120 vibrate at the vibration frequency 421 and the vibration frequency 411, respectively, equal to each other, the user may sense that the virtual vibration body 130 is placed between the first vibration device 110 and the second vibration device 120.
When the virtual vibration body 130 moves to be relatively close to the second vibration device 120, the apparatus for controlling a vibration transfer 100 may determine a vibration frequency 412 of the second vibration device 120 and a vibration frequency 422 of the first vibration device 110 as illustrated in FIG. 4.
In this instance, since the second vibration device 120 vibrates at the vibration frequency 412 greater than the vibration frequency 422 of the first vibration device 110, a user may sense that the virtual vibration body 130 is placed around the second vibration device 120 that vibrates relatively frequently.
That is, since a vibration frequency of the first vibration device 110 is relatively great at first, and decreases over time, and a vibration frequency of the second vibration device 120 increases over time, the user may sense that the virtual vibration body 130 moves from the first vibration device 110 side towards the second vibration device 120 side.
FIG. 5 illustrates an example of a method of transferring a vibration using a vibration magnitude according to an embodiment.
Referring to FIG. 5, when the virtual vibration body 130 is placed relatively closer to the first vibration device 110, the apparatus for controlling a vibration transfer 100 may determine a vibration magnitude 510 of the second vibration device 120 and a vibration magnitude 520 of the first vibration device 110.
In this instance, since the second vibration device 120 vibrates at the vibration magnitude 410 smaller than the vibration magnitude 520 of the first vibration device 110, a user may sense that the virtual vibration body 130 is placed around the first vibration device 110 that vibrates at a relatively great vibration magnitude.
Subsequently, when the virtual vibration body 130 moves by a manipulation of a user or an application to be placed between the first vibration device 110 and the second vibration device 120, the apparatus for controlling a vibration transfer 100 may determine a vibration magnitude 511 of the second vibration device 120 and a vibration magnitude 521 of the first vibration device 110 to be equal to each other as illustrated in FIG. 5. In particular, when an object associated with the virtual vibration body 130 moves by a manipulation of a user or an application, the apparatus for controlling a vibration transfer 100 may move the virtual vibration body 130 according to a movement of the object.
In this instance, since the first vibration device 110 and the second vibration device 120 vibrate at equal magnitudes the vibration magnitude 521 and the vibration magnitude 511, respectively, the user may sense that the virtual vibration body 130 is placed between the first vibration device 110 and the second vibration device 120.
When the virtual vibration body 130 moves to be relatively close to the second vibration device 120, the apparatus for controlling a vibration transfer 100 may determine a vibration magnitude 512 of the second vibration device 120 and a vibration magnitude 522 of the first vibration device 110 as illustrated in FIG. 5.
In this instance, since the second vibration device 120 vibrates at the vibration magnitude 512 greater than the vibration magnitude 522 of the first vibration device 110, a user may sense that the virtual vibration body 130 is placed around the second vibration device 120 that vibrates at a relatively great vibration magnitude.
That is, since a vibration magnitude of the first vibration device 110 is relatively great at first, and decreases over time, and a vibration magnitude of the second vibration device 120 increases over time, the user may sense that the virtual vibration body 130 moves from the first vibration device 110 side toward the second vibration device 120 side.
FIG. 6 illustrates an example of a method of controlling a vibration transfer according to an embodiment.
Referring to FIG. 6, a method of controlling a vibration transfer according to an embodiment may correspond to a method of providing, through a vibration, a user with a location of a virtual vibration body 130 corresponding to a vibration source when the virtual vibration body 130 is placed between a first vibration device 110 held by a user in a left hand 310 and a second vibration device 120 held by the user in a right hand 320.
When the virtual vibration body 130 is placed relatively closer to one of the first vibration device 110 and the second vibration device 120, a vibration value of a vibration device relatively close to the virtual vibration body 130 may be increased, thereby providing, through a vibration, the user with the location of the virtual vibration body 130.
However, when the virtual vibration body 130 is placed in a middle of the first vibration device 110 and the second vibration device 120, and a vibration value is determined based on a distance between the virtual vibration body 130 and a vibration device, the same vibration may occur in the first vibration device 110 and the second vibration device 120 and thus, the user may not determine the location of the virtual vibration body 130.
Thus, the apparatus for controlling a vibration transfer 100 according to an embodiment may periodically move the virtual vibration body 130 in a direction 610 toward the second vibration device 120 and in a direction toward the first vibration device 110, and control the first vibration device 110 and the second vibration device 120 according to a location of the moved virtual vibration body 130, thereby providing a user with a sensation that the virtual vibration body 130 exists vibrating in the middle of the first vibration device 110 and the second vibration device 120. In this instance, the apparatus for controlling a vibration transfer 100 may cause the user to sense that the virtual vibration body 130 vibrates in the middle rather than in motion by setting an infinitesimal distance the virtual vibration body 130 moves in the direction 610 and a distance the virtual vibration body 130 moves in the direction 620.
A variation of a vibration value according to a movement of the virtual vibration body 130 will be described with reference to FIG. 7.
The apparatus for controlling a vibration transfer 100 may clarify that the virtual vibration body 130 is placed in the middle of the first vibration device 110 and the second vibration device 120 by determining a vibration magnitude or a vibration frequency to be the same between the first vibration device 110 and the second vibration device 120, and determining a vibration timing or a vibration acceleration to be different between the first vibration device 110 and the second vibration device 120. For example, when the second vibration device 120 vibrates at the same vibration magnitude and vibration frequency as the first vibration device 110 after a period of about 0.5 seconds from a vibration of the first vibration device 110, a user may sense that the vibrating virtual vibration body 130 exists in the middle of the first vibration device 110 and the second vibration device 120.
FIG. 7 illustrates an example of a method of transferring a vibration using a vibration frequency according to an embodiment.
When the virtual vibration body 130 is placed in a middle of the first vibration device 110 and the second vibration device 120, the apparatus for controlling a vibration transfer 100 according to an embodiment may determine a vibration frequency 710 of the second vibration device 120 and a vibration frequency 720 of the first vibration device 110 to be equal to each other according to a distance between the virtual vibration body 130 and the second vibration device 120 and a distance between the virtual vibration body 130 and the first vibration device 110.
Subsequently, the apparatus for controlling a vibration transfer 100 may move the virtual vibration body 130 in the direction 610 toward the second vibration device 120, and determine a vibration frequency 711 of the second vibration device 120 and vibration frequency 721 of the first vibration device 110 according to a location of the moved virtual vibration body 130.
In this instance, a number of vibrations of the second vibration device 120 may increase since a vibration frequency is changed from the vibration frequency 710 to the vibration frequency 711, and a number of vibrations of the first vibration device 110 may decrease since a vibration frequency is changed from the vibration frequency 720 to the vibration frequency 721. Thus, a user may sense that the virtual vibration body 130 moves toward the second vibration device 120 in which a number of vibrations is increased.
Subsequently, the apparatus for controlling a vibration transfer 100 may move the virtual vibration body 130 in the direction 620 towards the first vibration device 110, and determine a vibration frequency 712 of the second vibration device 120 and vibration frequency 722 of the first vibration device 110 according to a location of the moved virtual vibration body 130.
Subsequently, a number of vibrations of the second vibration device 120 may decrease since a vibration frequency is changed from the vibration frequency 711 to the vibration frequency 712, and a number of vibrations of the first vibration device 110 may increase since a vibration frequency is changed from the vibration frequency 721 to the vibration frequency 722. Thus, a user may sense that the virtual vibration body 130 moves toward the first vibration device 110 in which a number of vibrations is increased.
The apparatus for controlling a vibration transfer 100 may provide a user with a sensation that the vibrating virtual vibration body 130 exists in the middle of the first vibration device 110 and the second vibration device 120 by periodically transmitting the vibration frequency 711 and the vibration frequency 712 to the second vibration device 120, and periodically transmitting the vibration frequency 721 and the vibration frequency 722 to the first vibration device 110.
FIG. 8 illustrates another example of a method of controlling a vibration transfer according to an embodiment.
When a user having a first vibration device 110 and a second vibration device 120 selects an object 810 on a screen 800 of a terminal, and moves the selected object 810 laterally, the apparatus for controlling a vibration transfer 100 may control the first vibration device 110 and the second vibration device 120 according to a movement 811 of the object 810 on the screen 800, thereby providing the user with a sensation that a virtual vibration body moves to a right side.
In this instance, the object 810 may correspond to an object such as a menu, a folder, and a file that may be selected and moved by a user in a terminal environment.
The apparatus for controlling a vibration transfer 100 may decrease a vibration value of the first vibration device 110, and increase a vibration value of the second vibration device 120 according to the movement 811 of the object 810.
That is, when the user moves the object 810 on the screen 800, the user may sense, through the first vibration device 110 and the second vibration device 120, the virtual vibration body moving in the same direction 812 and thus, may determine a movement of the object 810 through a sense of touch in addition to a sense of sight.
FIGS. 9 through 14 illustrate examples of a vibration device according to an embodiment.
As illustrated in FIG. 9, a first vibration device 110 and a second vibration device 120 according to an embodiment may correspond to a device grasped by a user in a left hand 910 and a right hand 920.
As illustrated in FIG. 10, the first vibration device 110 and the second vibration device 120 may be included in gloves 1000 worn by the user.
As illustrated in FIG. 11, the first vibration device 110 may be included in a keyboard 1110 controlled by the user using a left hand 310, and the second vibration device 120 may be included in a mouse 1120 controlled by the user using a right hand 320.
In this instance, the user may sense a vibration transfer through the keyboard 1110 and the mouse 1120 corresponding to generally used interfaces without use of a separate vibration device. That is, the apparatus for controlling a vibration transfer 100 may provide, using a vibration through the keyboard 1110 and the mouse 1120, the user with a movement of a unit or a movement of an object in a computer game using both of a keyboard and a mouse, thereby allowing the user to sense, through a sense of touch, a movement recognized by a sense of sight. When the user drags an object such as a map using the keyboard 1110 and the mouse 1120, the apparatus for controlling a vibration transfer 100 may feed back a sense of touch by changing a location of a virtual vibration body 130 according to a direction of the drag or a movement of a desired location.
As illustrated in FIG. 12, when the user performs an operation using the mouse 1120 without the keyboard 1110, the first vibration device 110 may be constructed in a separate vibrator 1200 so that the user may use the vibrator 1200 in the left hand 310, thereby providing the user with a vibration transfer according to an operation of the mouse 1120.
As illustrated in FIG. 13, the first vibration device 110 and the second vibration device 120 may be included in a portion 1310 held by the left hand 310 and a portion 1320 held by the right hand 320 in a bow interface. In this instance, when the user directs the bow interface at a screen 1300, and pulls and releases the portion 1320 held by the right hand 320, the apparatus for controlling a vibration transfer 100 may decrease a vibration value of the second vibration device 120, and increase a vibration value of the first vibration device 110, thereby providing the user with a sensation that a virtual vibration body 1330 moves towards the screen 1300.
