However, the network environment mentioned below includes at least one of the components illustrated in FIG. 1, but is not limited thereto.

A virtual reality terminal (hereinafter, a VR terminal) 100 is a device that supports a virtual reality interface and a display for virtual reality experience, and is used by a motion controller (MC) 200 to recognize a user's motion. By receiving a motion signal and reproducing the motion of a character in a VR image based on this, it can play a role of showing a VR image at the user's perspective.

At this time, the VR terminal 100 is installed and executed as one or more downloaded files such as an executable package installation file downloaded from a suitable program or application through a communication network. One or more programs or applications related to the capable system are pre-installed or are self-contained, so that VR images can be generated and/or played back.

Accordingly, the VR terminal 100 does not precisely match the motion of the motion controller to the position of the strokes of the character in a virtual environment that can be configured to transmit and receive data or signals through the motion controller 200 and the wired/wireless communication network 300. Independently construct a consonant input interface and a vowel input interface for intuitive and simple Hangul character writing by allowing strokes to be added by performing the corresponding strokes corresponding to the currently combined strokes in accordance with the required stroke direction, and motion controller 200 Consisting of an input unit 120 receiving a motion signal of a user using such an input interface through the wired/wireless communication unit 110 and a control unit 130 for completing a Korean character by combining the received motion signal and presenting it to the user. Can be.

For each of the configurations, the input unit 120 is basically an input interface and arranges an object having a size and shape suitable for cutting or stabbing in a virtual space suitable for cutting or stabbing, and displaying the character currently being written by the user around it. It is also possible to place a possible dial.

In addition, the input unit 120 is a consonant input interface. First, in order to receive a basic stroke (in a preferred embodiment of the present invention, a horizontal cut, a vertical cut, a diagonal cut, and a stabbing), an object having an appropriate size and shape to be cut or stabbed Arrange and present in a virtual space suitable for stabbing, and then place and present an object with an appropriate size and shape to be cut around the basic stroke in order to receive a break stroke. At this time, the cut object can be restored and presented to receive the continuous stroke.

For example, the input unit 120 first arranges and presents an object for receiving a basic stroke in a virtual space, and as an example, when a user cuts the presented object from left to right using the motion controller 200, a horizontal cut is input. An additional object for receiving the bottom break stroke is placed under the horizontal stroke and presented, and when a user cuts the object from top to bottom using the motion controller 200 and inputs a vertical cut, the side break stroke is input. The object is placed next to the vertical stroke and presented, and when the user cuts the object presented as another example from the upper right to the lower left using the motion controller 200, when a diagonal cut is input, an additional object for receiving the additional stroke is placed next to the diagonal stroke. Arranged and presented, when the user inputs a stab by using the motion controller 200 on the object presented as an additional example, the corresponding consonant input stage is terminated.

In addition, the input unit 120 is a vowel input interface in a virtual space suitable for cutting or stabbing an object having a size and shape suitable for cutting or stabbing in order to receive vowels in a cloth (ㅣ), ji (ㅡ), or phosphorus (·) input method. Arranged and presented, it is inputted through a consonant input interface on a character board around the consonant sound configured by the controller 130 and a vowel currently being written by the user may be combined and displayed.

The control unit 130 combines the horizontal cut, vertical cut, oblique cut and/or stabbing input through the consonant input interface of the input unit 120 to combine basic consonants (in a preferred embodiment of the present invention, a, b, ㅅ, ㅇ ), and complete the consonant by matching the basic consonant alone or the break stroke added to it to the stroke permutation combination. At this time, when a stroke suitable for the defined stroke permutation combination is input in the standard stroke order, the corresponding consonant is formed and completed. If the stroke does not correspond to the stroke permutation combination or is not input in the standard stroke order, the control unit 130 cancels the input and responds. You can inform the user that they cannot enter a stroke. However, if it is different from the standard stroke order but there is no ambiguity (for example, c, ㅂ, ㅊ, ㅍ, ㅎ), the consonant can be completed by matching the stroke permutation combination. In addition, when it is unclear which consonant is being input, guidance such as showing the corresponding consonants by overlapping the above-described character board may be provided.

Specifically, in accordance with a preferred embodiment of the present invention, the control unit 130 first uses a consonant input interface of the input unit 120 as a basic consonant: i) a basic horizontal stroke and then an additional lower angled stroke a, ii) after the basic vertical stroke. If additional side break strokes are input, ㄴ, ⅲ) If additionally after the basic diagonal line stroke is input, ㅅ, ⅳ) If a stab is input, ㅇ is formed. And ⅴ) If b stroke is input in addition to the basic horizontal stroke or horizontal stroke is input in addition to the basic consonant b, then c, ⅵ) if a horizontal stroke is entered in addition to the basic consonant ㄱ, ㄹ, ⅶ) in addition to the basic vertical stroke, a horizontal stroke after a stroke When is input, ㅁ, ⅷ) When a continuous horizontal stroke is entered in the continuous vertical stroke, or if a vertical stroke following the continuous horizontal stroke is entered in addition to the basic vertical stroke, ㅂ, ⅸ) If a ㅅ stroke is input in addition to the basic horizontal stroke, ㅈ, ⅹ) Additional horizontal strokes to the basic vertical stroke When the next stroke is entered or additional horizontal strokes are entered, ㅊ, ⅹⅰ) If a horizontal stroke is input in addition to the basic a stroke, ㅋ, ⅹⅱ) In addition to the basic horizontal stroke If the next horizontal stroke is input, ⅌, ⅹⅲ) is added to the basic horizontal stroke. When a horizontal stroke is input after a continuous vertical stroke, ㅍ, and ⅹiv) If a horizontal stroke is entered in addition to the basic vertical stroke or a horizontal stroke is input in addition to the continuous horizontal stroke, the consonant is completed. As described above, in the case of consonants with a tap (for example, ㅊ, ㅎ), both horizontal and vertical strokes can be allowed as the tap input.

In addition, when the consonants ㄱ, ㄷ, ㅂ, ㅅ, and ㅈ are completed to configure the paired consonants, the controller 130 may present an additional cutting object through the input unit 120.

FIG. 2 is a view showing a state in which a consonant A is input according to a preferred embodiment of the present invention, and FIG. 3 is a view showing a state in which a double consonant  is input according to a preferred embodiment of the present invention.

In addition, the control unit 130 combines horizontal cutting, vertical cutting, and/or stabbing input through the vowel input interface of the input unit 120 and vowels in a known cloth (ㅣ), paper (ㅡ), and phosphorus (·) input method. Configure. For example, according to a preferred embodiment of the present invention, the control unit 130 configures ㅐ when a vertical cut is first input, ㅏ when an additional stabbing is input, and then ㅐ when a vertical cut is input.

The motion controller 200 recognizes the user's motion to be reflected in the VR image to be displayed on the VR terminal 100, that is, changes in the user's position, orientation, and angle, and proceeds with the VR experience. As a device for this purpose, it may include an inertial measurement unit (IMU).

The Inertial Measurement Unit (IMU) is a device that recognizes the motion situation of a moving object by measuring the speed and direction, gravity, and acceleration of a moving object using a combination of an accelerometer and an angular velocity meter, and sometimes a geomagnetic and altimeter. These IMUs generally have a 3-axis accelerometer and a 3-axis angular velocity meter built-in, so in a three-dimensional space consisting of the x-axis, y-axis and y-axis, the motion of the moving object moves in the direction of movement, the transverse direction, and the acceleration in the height direction (linear movement inertia. ) And the degree of motion of a moving object, such as roll, pitch, and yaw angular velocity (rotational inertia), and azimuth measurement through a geomagnetic machine. And it is possible to calculate the velocity and attitude angle of the moving object by integrating the acceleration and angular velocity obtained from the IMU.

That is, in the present invention, the motion controller 200 recognizes the user's motion in a three-dimensional space consisting of the x-axis, y-axis, and y-axis. At least one of a roll, pitch, and yaw angular velocity, which is the acceleration of the direction and the degree of motion, may be included, and the motion performed in three dimensions is the user's body in a horizontal or vertical direction. It may be made including rotating or moving.
