Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motion simulator control apparatus and a motion simulation system including the motion simulator control apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a tactile sensing technology, and more particularly, to a motion simulator control device that can be applied to a motion simulator interlocked with contents and a motion simulation system including the same.

4D technology combines 3D stereoscopic 3D with physical effects such as water droplet ejection, seat vibration and motion, glare lighting, odor emanating, and other technologies that add cinematographer and amusement park user experience Quot;

The 4D technology is not necessarily based on 3D stereoscopic images, but the 3D stereoscopic image itself is not a 3D image but a 2D stereoscopic image can be implemented by providing a physical effect in a 4D facility.

Therefore, the most important characteristic of 4D technology is to give users a sensory-type physical stimulation. The characteristic of 4D technology is to improve the immersion of contents by using multi-sensory of human. In other words, while users mainly use visual and auditory sense when watching a general movie, 4D technology stimulates various senses such as tactile sense and smell through liquid injection, odor emission and vibration.

The origins of 4D technology and content can be seen as simulators used in military training. A flight simulator is a typical example of a simulator, in which a flight instructor is designed to practice flight manipulation techniques through a simulator instead of an expensive flight, and the motion control technique used in the flight simulator has been applied to 4D. Since then, 4D technology has begun to be used in arcade game machines that provide 2D images and physics manipulation as the arcade game industry develops.

Full-fledged 4D technology, which provides stereoscopic 3D and physics effects, began to be used at attractions in the amusement park for about 20 years.

In recent years, with the development of digital projection technology and stereoscopic projectors in the field of 3D stereoscopic film, a screening facility which was not inconvenient for long time screening was developed, and as a result of opening a full-length stereoscopic movie having a screening time of 2 hours or more, In addition, the 4D movie theater for the purpose of watching feature films is beginning to appear.

On the other hand, the physical effect technology of 4D can be classified into categories such as air, vibration, seat motion control, water, smell, light, One of the most difficult techniques is motion control technology that controls seat motion.

Motion control technology is a technology that controls direction and speed of motion simulator according to motion or gaze in video contents by interlocking with contents and it is the factor that has the greatest influence on user's sensibility among 4D physics effect technologies .

Conventionally, in order to control a motion simulator, a method of controlling a motion simulator by using a joystick as an input device and manipulating a joystick to suit contents of contents is used.

However, the technique of controlling the motion using the joystick reduces the intuitiveness of the operation because the motion of the motion simulator is controlled by converting the position value of the joystick moving on the two-dimensional (X, Y axis) into the motion of the three-dimensional motion simulator . Also, since the motion control precision is determined according to the skill of the operator who operates the joystick, the position value extracted from the motion of the joystick may not be precise, and in such a case, And the quality of the user's sensation is lowered.

SUMMARY OF THE INVENTION An object of the present invention is to provide a motion simulator controller capable of intuitively controlling a motion simulator and improving a bodily sensation quality irrespective of skill of an operator operating the motion simulator.

Another object of the present invention is to provide a motion simulation system including the motion simulator control apparatus.

According to an aspect of the present invention, there is provided an apparatus for controlling a motion simulator, the apparatus comprising: a gyroscope sensor for providing a motion sensing signal corresponding to a motion; And a communication unit for providing the motion control information to the motion simulator in accordance with the control of the processing unit.

According to the above-described motion simulator control apparatus and the motion simulation system including the same, the sensing value obtained by using the gyroscope sensor is mapped with the motion of the motion simulator considering the mechanical and / or electrical limitations of the motion simulator, And provides the generated motion control information to the motion simulator after generating the information.

Therefore, the axis height and the moving speed of the motion simulator can be intuitively controlled, and the motion simulator can be precisely controlled. In addition, since the motion simulator can be precisely controlled according to the contents of the linked contents, satisfaction of the user's feeling can be improved.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In order to facilitate the understanding of the present invention, the same reference numerals are used for the same constituent elements in the drawings and redundant explanations for the same constituent elements are omitted.

The 'motion simulator' used throughout the present specification is used to refer to various objects providing motion to the user in accordance with the motion control, and may be configured in various shapes. For example, the motion simulator can be implemented in various forms such as a chair of a viewer installed in a 4D theater, a chair for a game, or a cockpit for exercising an aircraft, a ship, or a submarine.

1 is a block diagram showing a configuration of a motion simulator system to which a motion simulator control apparatus according to an embodiment of the present invention is applied.

Referring to FIG. 1, the motion simulator system may include a motion simulator control device 100, a motion simulator 200, and a display device 300.

The motion simulator control apparatus 100 includes a gyroscope sensor and generates motion control information of the motion simulator 200 by mapping a gyroscope sensed value corresponding to a user's operation with motion of the motion simulator 200 , And provides the generated motion control information to the motion simulator (200).

The motion simulator control apparatus 100 may be implemented in various forms including a gyroscope sensor. For example, the motion simulator control apparatus 100 may be implemented as a mobile terminal equipped with a gyroscope sensor, or may be implemented as a game controller or a remote controller having a gyroscope sensor.

The motion simulator 200 has a plurality of actuators and generates torque by driving a plurality of actuators corresponding to the motion control information provided from the motion simulator control apparatus 100. [

Alternatively, the motion simulator 200 may store the motion control information provided from the motion simulator control apparatus 100 in advance in the non-volatile storage means in synchronization with the content of the linked content, And may be configured to drive a plurality of actuators in accordance with the matched motion control information.

Here, the motion simulator 200 may be configured in various shapes in which the user can experience the motion, and may be composed of, for example, a chair for a theater, a cockpit for piloting exercises such as an aircraft, a ship, and a submarine.

The display device 300 is a device for displaying a reproduction screen of contents, and may be configured of, for example, a projector, an LCD, a PDP, or the like.

Further, the display apparatus 300 can display a message provided from the motion simulator control apparatus 100. [ For example, the display apparatus 300 may be connected to the motion simulator control apparatus 100 in a wired or wireless manner to display a warning, error, or the like provided from the motion simulator control apparatus 100.

2 is a block diagram showing a configuration of a motion simulator control apparatus according to an embodiment of the present invention.

2, the motion simulator control apparatus 100 includes a gyroscope sensor 110, a processing unit 120, a communication unit 130, an input unit 140, an output unit 150, and a storage unit 160 .

The gyroscope sensor 110 senses the motion of the motion simulator control apparatus 100 moving according to the user's operation and provides a motion sensing signal as a sensing result value to the processing unit 120. [ Here, the gyroscope sensor 110 may be constituted by a multiaxial sensor of at least a three-axis (X, Y, Z) sensor and may be provided with a three-axis angle (or tilt) value corresponding to the motion of the motion simulator control apparatus 100 Processing unit 120, as shown in FIG.

The processing unit 120 generates motion control information by mapping the motion sensing signal provided from the gyroscope sensor 110 with the motion of the motion simulator 200 and transmits the generated motion control information to the motion simulator 200 ).

Since the motion simulator control apparatus 100 according to the embodiment of the present invention controls the motion of the motion simulator 200 using the gyroscope sensor 110 as described above, the motion simulator 200 may be a separate gyroscope It is not necessary to provide the sensor 110. In the present invention, the processing unit 120 maps the motion sensing signal provided from the gyroscope sensor 110 to the motion of the motion simulator 200 in consideration of the operation limit of the motion simulator 200, It is not necessary to perform the operation of the gyroscope exceeding its operation limit as it is.

In the case where the motion simulator 200 is composed of three axes and controls the motion of the motion simulator 200 by using the two-dimensional joystick, conventionally, the behavior radius of the two-dimensional joystick is divided into three regions by 120 degrees, And the control is performed by mapping the area to the height of each axis. Although such a control method can theoretically map the motion of the motion simulator 200 to the motion radius of the two-dimensional joystick, in reality, the motion accuracy of the motion simulator 200 depends on the skill of the operator manipulating the joystick Respectively.

For example, when tilting the joystick forward or backward, the first axis of the motion simulator 200 can be moved clearly, but it is not easy to move the second and third axes at the same speed and position. That is, when the joystick is tilted backward, the axis 1 is raised and the axes 2 and 3 are lowered. However, when the joystick is tilted forward, the axes 2 and 3 do not rise above a predetermined height . This problem is caused by the inaccuracy of the position value of the joystick, and a combination of a joystick and a button key may be used to compensate for this. Therefore, a method of controlling the motion simulator 200 using the joystick requires a skilled operator capable of controlling the joystick very precisely in conjunction with the content.

In order to overcome the disadvantages described above, the motion simulator control apparatus 100 according to an embodiment of the present invention uses an intuitive gyroscope sensor 110 with high control accuracy.

Particularly, in the motion simulator control apparatus 100 according to an embodiment of the present invention, when the processing unit 120 matches the slope of the motion simulator 200 itself and the rotation angle of the gyroscope, The movement of the motion simulator 200 can be precisely controlled irrespective of the motion of the user.

In the present invention, the gyroscope sensor 110 can sense motion without any particular constraint. However, the point and motion simulator 200 may be configured to detect movement of the gyroscope sensor 110, Lt; RTI ID = 0.0 > 200 < / RTI >

2, the communication unit 130 provides motion control information provided from the processing unit 120 to the motion simulator 200. [ The communication unit 130 may be constituted by wireless communication means such as WiFi, Bluetooth, infrared, UWB (Ultra Wide Band), or the like, or may be constituted by wired communication means.

The input unit 140 may include input means such as a touch pad, a touch screen, a button, a key, and the like, and provides an input signal corresponding to a user's touch input or key or button operation to the processing unit 120.

The output unit 150 may include a display device, a speaker, and a vibrator. When an error or a warning condition occurs in the control process of the motion simulator 200, an error or warning message is generated in accordance with the control of the processing unit 120 It may be displayed through a display element, output a warning sound through a speaker, or may generate vibration.

The storage unit 160 may be a nonvolatile memory and may store the control method of the motion simulator 200 performed by the processing unit 120 or sequentially store the motion control information generated by the processing unit 120 . For example, the motion control information generated by the processing unit 120 may be sequentially stored in the storage unit 160 in synchronization with the time information.

3 is a block diagram illustrating a configuration of a motion simulator according to an embodiment of the present invention.

Referring to FIG. 3, the motion simulator 200 may include a motion processor 210, a driver 220, and an actuator 230.

The motion processing unit 210 provides a motion control signal to the driving unit 220 in accordance with the motion control information provided from the motion simulator control apparatus 100. Here, the motion processing unit 210 may receive motion control information from the motion simulator control apparatus 100 through a wired communication interface or a wireless communication interface, or may synchronize with the content to be linked and read out previously stored motion control information, And to provide the motion control signal to the driving unit 220 based on the motion control information. The motion processor 210 may be implemented as firmware in a separate chip and mounted on the motion simulator 200. The motion processor 210 may be configured to include motion control information provided from the motion simulator controller 100. [

The driving unit 220 provides a driving control signal for driving the actuator 230 in accordance with the motion control signal provided from the motion processing unit 210. Here, the drive control signal may be composed of a pulse signal having a size and a width corresponding to the motion control signal, for example.

The actuator 230 may include a number of motors 231 corresponding to the driving shafts of the motion simulator 200. Each of the motors 231 may have a speed corresponding to the driving control signal provided from the driving unit 220, And provides torque to the motion simulator 200 by rotating at an angle. For example, when the motion simulator 200 is composed of three axes, the actuator 230 may include three motors 231 corresponding to each axis.

4 is a flowchart illustrating an example of a motion sensing signal mapping method of the motion simulator control apparatus 100 according to an embodiment of the present invention.

Referring to FIG. 4, the processing unit 120 acquires a motion sensing signal provided from the gyroscope sensor 110 (S401).

Then, the processing unit 120 determines whether the acquired motion sensing signal exceeds the motion limit of the motion simulator 200 (S403). For example, when the motion simulator 200 can move up to 100 degrees in the x axis, when the x axis value of the acquired motion sensing signal indicates 130 degrees, the processing unit 120 outputs the acquired motion sense signal to the motion simulator 200) of the moving object.

If it is determined in step S403 that the acquired motion sensing signal exceeds the motion limit of the motion simulator 200, the processing unit 120 ignores the acquired motion sensing signal in step S405, An alarm indicative of the movement limit of the camera 200 is output (S407). Here, the processing unit 120 may output an alarm through the output unit 150 or generate an alarm sound or vibration to output an alarm to the motion simulator control apparatus 100 itself, and may output a motion simulation An alarm message may be displayed on the display device 300 by transmitting an alarm message to the display device 300 of the system.

On the other hand, if it is determined in step S403 that the acquired motion sensing signal does not exceed the motion limit of the motion simulator 200, the processing unit 120 determines whether the acquired motion sensing signal is within the motion range of the motion simulator 200 Generates motion control information by mapping with a specific movement position, and provides the generated motion control information to the motion simulator 200 (S409).

Thereafter, the processing unit 120 determines whether the control of the motion simulator 200 is terminated (S411) and repeats the above process while the control of the motion simulator 200 is continued.

5 is a flowchart illustrating another example of a motion sensing signal mapping method of the motion simulator control apparatus 100 according to an embodiment of the present invention.

Referring to FIG. 5, the processing unit 120 of the motion simulator control apparatus 100 performs an initialization process. In the initialization process, the processing unit 120 performs synchronization with the motion simulator 200 using the absolute value of the gyroscope sensor 110 (S501). The initialization process may be performed only once at an initial stage, or may be selectively performed when an error occurs, in order to reduce the control error by matching the operations of the gyroscope sensor 110 and the motion simulator 200.

Then, the processing unit 120 acquires a motion sensing signal from the gyroscope sensor 110 every predetermined period (S503).

Thereafter, the processing unit 120 calculates the difference between the sensing value indicated by the motion sensing signal obtained at the current time (or the current period) and the sensing value acquired at the previous period (S505), and outputs the calculated difference To the motion simulator 200 (S507).

When the motion simulator 200 receives the difference between the sensed value of the previous period and the sensed value of the current period, the motion simulator 200 may drive the actuator 230 according to the difference value.

Alternatively, in step S507, the processing unit 120 may generate motion control information corresponding to the difference value of the calculated motion sensing values, and may provide the generated motion control information to the motion simulator 200. [

Thereafter, the processing unit 120 determines whether the control of the motion simulator 200 is terminated (S509), and repeats the above process while the control of the motion simulator 200 is continued.

5 and the processing performed in steps S503 to S507 may be performed by the input unit 140 (e.g., a touch screen, a key, a button, etc.) provided in the motion simulator control apparatus 100 The user can directly switch between them.

Alternatively, in another embodiment of the present invention, a small motion simulator control device (not shown) including the mechanical and / or electrical limit characteristics of the actual motion simulator 200, including the configuration of the motion simulator control device 100 shown in Fig. 2 The user may freely operate the small motion simulator control apparatus 100 and control the motion of the motion simulator 200 within the same limit as that of the actual motion simulator 200. [

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
