Description

Real-Time Positioning Method of Orbit-Type Ride

The present disclosure relates to a ride, a ride system, a computer program and a method capable of real-time position measurement.

Virtual reality (VR) refers to the interface between a human and a computer that makes a particular environment or situation computerized, making the user feel as though they are interacting with the actual environment and environment. In order for a user to feel a sense of reality through virtual reality, it is necessary to provide information obtained through the user's five senses such as sight, hearing, and tactile sense. In particular, devices that require the greatest amount of information among the users' senses have been developed, such as eyes, in accordance with the development of virtual reality technology. The result of this effort is a head mounted display (HMD).

As the development of the HMD progresses, augmented reality (AR) or mixed reality (MR), which combines virtual images or images having additional information in real time in a real space into a single image, Research is also actively being conducted. The augmented reality or mixed reality is different from the virtual reality that is constructed only in the virtual world in that the distinction between reality and virtual is ambiguous by overlapping a three-dimensional virtual image created by computer graphics on the actual background or image that the user is viewing .

Virtual reality, augmented reality, and mixed reality contents using HMD have already been widely used in the industry. Various VR technologies have been applied to theme parks around the world depending on the type of user experience. In particular, a ride (for example, a roller coaster), which is a major part of a theme park attraction, is not only essential in a theme park but also can be installed easily in a virtual reality-based roller coaster without physically deforming the existing roller coaster facility , It is expected that demand will increase in the future because various VR contents can provide different experiences in the same route.

European patent EP2138213 B1 entitled " Ride, in particular rollercoaster " discloses an augmented reality (AR) roller coaster. However, this prior art shows a limit to synchronization of content reproduction. That is, synchronizing the HMD contents according to the movement of the viewer is essential in high-speed ride, and when the location information is provided using the single sensing method, the accurate position value can not be determined due to the wheel shake, physical wear and slip, do. If these errors are accumulated, there will be inconsistency between the viewer circulation on the actual orbit and the HMD contents that are visible, causing dizziness. Conventionally, in order to prevent dizziness in the event of such inconsistency, a method of forcibly stopping the HMD contents was used, which is said to be the biggest problem to be solved by the VR roller coaster.

Therefore, in order to solve such a problem, the present invention has been made to solve the above problems, and it is an object of the present invention to provide a navigation system capable of accurately measuring the real- And a computer program for controlling a ride system, a control method of the ride system, and a computer program for controlling the ride system such that motion of the vehicle is interlocked without errors to prevent sensory incongruity or viewpoint latency. Furthermore, the present invention can be realized through simple installation when using existing roller coaster facilities in implementing such a ride system.

In the following detailed description, reference is made to the accompanying drawings which form a part hereof. In the drawings, like reference numerals identify generally similar components, unless otherwise indicated in the context. The illustrative embodiments set forth in the description, drawings, and claims are not intended to limit the scope of the claims. Other embodiments may be utilized and other modifications may be made without departing from the spirit and scope of the objects set forth herein. It will be readily appreciated that aspects of the present disclosure as generally described herein and shown in the drawings may be arranged, substituted, combined, separated, and designed in various different configurations, all of which are explicitly considered herein.

1 schematically illustrates an exemplary real time ride position measurement system arranged in accordance with at least some embodiments described herein. For example, virtual reality-based technology can be served on the ride of a theme park such as a roller coaster. Visitors can experience various virtual reality-based environments (eg, SF, horror, shooting games, etc.) according to the viewer's choice by wearing an HMD and boarding a real roller coaster. In order to serve a virtual reality-based ride, virtual reality-based contents, such as virtual reality contents, augmented reality contents or mixed reality contents, may be perfectly reproduced according to the type of the actual ride (for example, the length of rail or track, curvature, And accurate positioning data of the HMD worn by the visitor should be secured. Currently, the commercialized technology is a single sensing method using a single sensor. The sensor signal is converted into a moving distance, and this information is transmitted to the HMD as a Bluetooth signal to synchronize the viewpoint of the virtual reality contents with the viewer. However, this single sensing method has a limitation in that the position measurement information value is often lost. For example, the sensor calculates the position value by the rotation period of the wheel of the vehicle. Due to the characteristics of the roller coaster, when the rotation of the wheel slips due to rapid rotation and vibration, accurate sensor signals can not be obtained. In addition, an error in the position value may occur depending on the urethane wear state of the wheel of the roller course. Due to the sensory inconsistency caused by the error of the position value, the viewer wearing the HMD experiences dizziness. Conventionally, in order to prevent such dizziness, the HMD automatically terminates the virtual reality contents as a temporary measure, so that the viewer can not fully enjoy the virtual reality-based ride.

1, the present invention uses a ride including a start receiving unit 110, a signal receiving unit 120, an infrared receiving unit 130, and a control signal transmitting unit 140 To provide a virtual reality-based content that is convenient and precisely interlocked with a trajectory for a user wearing the HMD. The control signal transmission unit 140 receives the positional relative value of the ride from the signal receiving unit 120 and the absolute positional value of the ride from the infrared ray receiving unit 130 in association with the virtual reality- We propose a system that measures the position of a ride in real time. That is, roughly speaking, while measuring the position relative value by calculating the number of revolutions of the wheel or wheel, the absolute positional value on the rail on which the ride is actually passing is measured, and the position of the stable and accurate ride And a system for calculating a value. The signal receiving unit 120 receives an encoder signal relating to the rotation of the wheel from, for example, an optical or magnetic rotary encoder, which is used to obtain information about the travel distance (relative position) . When the infrared signal radiated from the infrared transmitter is reflected on the rail, the infrared receiver 130 receives the reflected infrared signal and can obtain the information about the speed according to the absolute position and the absolute position of the ride. The difference between the speed according to the relative position and the speed according to the absolute position in each section can be calculated as the section speed increase / decrease value. Furthermore, the time at which an error occurs when an error occurs between the position relative value and the position absolute value is checked, and the reproduction speed of the virtual reality contents is corrected in real time to solve the delay phenomenon of the content reproduction image in the dynamic ride at high speed . In addition, by implementing a system capable of automatically reproducing the virtual reality contents or determining the initial playback speed and / or the reproduction position by receiving the start signal generated when the ride is started through the start receiving unit 110, Based ride. Specifically, the start receiving section 110 can receive a start signal including a start speed from the start sensor. The start sensor may be implemented to sense the start of the ride and generate a start signal in any manner known to those skilled in the art. For example, the start sensor can detect the start of the ride from the encoder signal detecting the first rotation of the wheel, or can be communicatively connected to an external device that controls the start of the ride. When the start signal, the start speed, the moving distance, the section speed, and the section speed increase / decrease value are obtained from the start receiving section 110, the signal receiving section 120, and the infrared receiving section 130, It is possible to correct the reproduction speed and generate the control signal rule therefor. The generated control signal can be transmitted from the control signal transmission unit 140, for example, in a Bluetooth manner to the HMD. The control signal transmitter 140 can apply Low Duty Cycle Directed Advertising ('Duty Cycle Directed Advertising'), and the convenience of the ride user can be enhanced by the automatic reconnection function. The control signal can control the content playback speed of the HMD that displays the virtual reality contents. In some embodiments, the HMD content may be stored in a user-mounted HMD. In another embodiment, the HMD content may be added as the user scans the QR code via the HMD. Such a real-time position measurement system can be applied not only to calculating position values of all attraction mechanisms including roller coasters, but also to a wide range of VR and VR KTX vehicles such as railroad, traffic simulation, and the like.

FIG. 2 illustrates an exemplary system 200 for measuring a position relative value of a ride, arranged in accordance with at least some embodiments described herein. The user mounts the HMD 250 on which the virtual reality contents are displayed, which can receive a control signal (for example, a Bluetooth signal) from the control signal transmitting unit 240, on the head of the carrier 220. Although a ride including one carrier 220 is shown in FIG. 2, a ride may be realized by connecting two or more carriers. One or more wheels 230 may be coupled to the carrier 220. One or more wheels 230 may contact the rail or track 210 to induce movement of the ride.

The enlarged view shown on the left side of FIG. 2 is a sectional view seen from the front of one or more wheels 230 and the track 210, and the encoder 235 may be connected to one or more wheels 230. Encoder 235 may be a rotary encoder. Encoder 235 may also be optical or magnetic. Encoder 235 may generate an encoder signal by detecting rotation of one or more wheels 230. [ When the rotation is detected from the encoder signal, the rotation speed is calculated, and the movement distance of the ride can also be calculated by using the diameter and the number of revolutions of the wheel. The travel distance of the ride calculated through the rotation of the wheel corresponds to the positional relative value of the ride.

FIG. 3 (a) illustrates an exemplary system 300 for measuring the absolute position of a ride, arranged in accordance with at least some embodiments described herein. The components of FIG. 3, labeled similarly to the components of FIG. 2, may be understood to have the same or similar functionality as the components of FIG. The user mounts the HMD 350 on the head 320, on which the virtual reality contents are displayed, capable of receiving a control signal (for example, a Bluetooth signal) from the control signal transmitting unit 340, on the head. Although a ride including one carrier 320 is shown in FIG. 3, a ride may be realized by connecting two or more carriers. One or more wheels 330 may be coupled to the carrier 320. One or more wheels 330 may contact orbit 310 to induce movement of the ride. On the track 310, a plurality of absolute position indicating portions 360 may be provided spaced apart from each other. The plurality of absolute position indicating portions 360 may be provided at a predetermined interval (for example, 5 m) near the center of the track 310 or on the side surface thereof. The plurality of absolute position indicating portions 360 may be formed to reflect infrared rays. The plurality of absolute position display units 360 may each have unique data values so as to indicate positions on the trajectory 310 on which the ride actually passes, that is, position absolute values of the ride. The carrier 320 may include an infrared transmitting / receiving unit 350. The infrared transmission / reception unit 350 may use one component that performs both the transmission function of the infrared signal and the reception function of the infrared signal, or a component having the transmission function of the infrared signal and the component having the reception function of the infrared signal Can be used. The infrared transmitting / receiving unit 350 can transmit an infrared signal toward the plurality of absolute position indicating units 360. [ The infrared signal transmitted from the infrared transceiver unit 350 is transmitted to the absolute position display unit 360 through the plurality of absolute position display units 360. In the case where the infrared transceiver unit 350 is located at a position corresponding to the absolute position display unit, Is reflected from the position display unit 360, and then is directed to the infrared transmitting / receiving unit 350 again. The infrared transmitting / receiving unit 350 can detect the reflected infrared signal. The infrared transmitting and receiving unit 350 transmits infrared signals toward the plurality of absolute position indicating units 360 and is installed on the lower side of the carrier 320 to easily receive the infrared signals reflected from the plurality of absolute position indicating units 360 .

In one embodiment, the plurality of absolute position indicators 360 may be a high-luminance reflecting bar. When the plurality of absolute position display units 360 are high luminance reflective units, the corresponding infrared transmission / reception unit 350 may include at least one infrared ray sensor. Fig. 3 (b) shows an exemplary high-luminance reflective bar. The high-luminance reflective bar may include at least one reflective portion and a non-reflective portion. The reflective portion is formed of a material that can reflect infrared rays, and the non-reflective portion is formed of a material that does not reflect infrared rays. For example, the non-reflecting portion may be formed of a material capable of absorbing infrared rays. Referring to FIG. 3 (b), a portion shown by a rectangle in the high-luminance reflective bar represents a reflective portion, and the other portion represents a non-reflective portion. At least one infrared ray sensor of the infrared ray transmitting / receiving unit 350 is installed on the lower side of the carrier 320. Herein, the infrared ray transmitting / receiving unit 350 of the ride When passing through the absolute position indicating section 360, can correspond to at least one reflecting section or non-reflecting section in a substantially vertical direction. When the infrared sensor corresponds to the reflecting portion, the infrared sensor transmits an infrared signal toward the reflecting portion, and the reflecting portion reflects the infrared signal. Next, the infrared sensor at the position corresponding to the reflection portion can detect the reflected infrared signal. When the infrared sensor corresponds to the non-reflecting part, the infrared sensor transmits the infrared signal toward the non-reflecting part, and the non-reflecting part prevents the infrared signal from being reflected. Thus, the infrared sensor at the position corresponding to the non- Can not be detected. Therefore, for example, when the value of the data in the case where the reflection portion exists at the position corresponding to the vertical direction in the infrared sensor is represented by " 1 ", and the value of the data is "Quot; 0 ", the high-brightness reflective bar may represent the absolute position of the ride on the trajectory 310 in a binary method.

Figure 4 shows first and second embodiments of an absolute position indicator and an infrared transceiver that are capable of measuring the position absolute value of the ride, arranged in accordance with at least some embodiments described herein. The components of FIG. 4 labeled similarly to the components of FIG. 3 may be understood to have the same or similar functionality as the components of FIG. 4, two wheels 430 and infrared transmitters /

receivers

450 and 455 among the components of the carrier, an orbit 410 and an absolute

position display unit

460 and 465, respectively. Referring to FIG. 4, two wheels 430 connected to the carrier of the ride contact the track 410, and the ride can be moved by rotation of the wheel 430 on the track 410.

In the first embodiment, as described above with reference to FIG. 3, a high-luminance reflective bar 460 including a reflective portion and a non-reflective portion may be provided near the center of the orbit 410. In addition, at least one infrared ray sensor 450 may be installed at a position corresponding to the carrier in the normal direction to the high-luminance reflective bar 460. At least one infrared sensor 450 may be installed at the lower portion of the carrier to facilitate transmission and reception of the high-intensity reflection bar and the infrared signal. Each of the infrared sensors 450 corresponds to the reflective portion or the non-reflective portion of the high-luminance reflective bar 460 in the normal direction, and the infrared signal transmitted from the infrared sensor 450 is transmitted to the reflective portion or the non-reflective portion, respectively. When the infrared sensor 450 corresponds to the reflection portion, the infrared sensor 450 can receive the infrared signal reflected from the reflection portion. When the infrared sensor 450 corresponds to the non-reflecting portion, the non-reflecting portion does not reflect the infrared ray, so that the infrared ray sensor 450 can not receive the reflected infrared ray signal. Accordingly, when the infrared sensor 450 corresponds to the reflection portion, the received infrared signal is represented by a data value of " 1 ". When the infrared sensor 450 corresponds to the non-reflection portion, &Quot; and the absolute value of the position of the ride can be represented by the binary method. That is, when the infrared signals received or not received by the respective infrared sensors 450 through the high-luminance reflection bar are combined, the intrinsic data value of the high-luminance reflection bar can be obtained.

In the second embodiment, a mirror reflecting plate 465 may be provided near both sides of the orbit 410. A plurality of mirror reflectors 465 may be installed at regular intervals on the trajectory 410. The plurality of mirror reflectors 465 may be formed only of a material capable of reflecting infrared rays. At least one photo sensor 455 may be installed at a position of the carrier corresponding to the normal direction to the mirror reflector 465. At least one photosensor 455 may be mounted on the lower side of the carrier to facilitate transmission and reception of infrared signals with the mirror reflector 465. The mirror reflector 465 can receive the infrared signal from the photosensor 455 and reflect it. The photosensor 455 can receive the reflected infrared signal. Thus, when the ride starts, the ride sets the number of initial counters to zero and increases the number of counters by a predetermined value each time the photosensor receives the reflected infrared signal from the mirror reflector . The predetermined value may be, for example, an interval at which one or a plurality of mirror reflectors are spaced apart from each other (for example, a predetermined value is set to 5 if the distance is 5m). Thus, the position absolute value of the ride can be calculated based on the number of counters. The set of mirror reflector 465 and photosensor 455 may be applicable to a rail structure in which the high-intensity reflector bar 460 can not be installed. For example, in a rail structure in which the high-luminance reflective bar 460 can not be installed, there is no part that can be installed near the center of the orbit 410, and when the high-luminance reflective bar 470 can not be installed near the center of the orbit 410 to be.

4, the set of the infrared sensor 450 and the high-intensity reflection bar 460 (the first embodiment), the photosensor 455, and the mirror reflector 465 of the infrared transmission / reception unit and the absolute position display unit, (Second embodiment) has been described. When implementing the ride system, only the first embodiment or the second embodiment may be used so as to conform to the shape of the orbit 410, or the first embodiment and the second embodiment may be used together. Any of the infrared transmitting / receiving units and the absolute position indicating unit, which includes the first and second embodiments described herein, can be configured such that the infrared signal transmitted from the infrared transmitting unit is reflected by the absolute position indicating unit capable of reflecting infrared rays, And the reflected infrared signal is detected. Therefore, in comparison with the case where the infrared ray transmitter for radiating an infrared ray signal is installed directly on the track and the infrared ray receiver installed on the ride receives the infrared ray signal, the present invention is simple in installation, And has the advantage of being able to implement a position location system. That is, when the infrared transmitter is directly installed on the track, a separate power source must be supplied to the track. However, in the case where both the infrared ray transmitter and the infrared ray receiver are provided on the carrier and the absolute position indicator capable of reflecting the infrared ray signal is installed on the orbit as in the present invention, there is no need to install a separate power source in the orbit, It is easy to pay. 3 and 4, the infrared transmitting / receiving unit includes both the infrared transmitting unit and the infrared receiving unit. However, it is needless to say that the infrared transmitting unit and the infrared receiving unit may be separately installed in the respective rides in a suitable manner.

Figure 5 illustrates a process of an exemplary sensor controller arranged in accordance with at least some embodiments described herein. The sensor controller may be included in the carrier. The sensor controller receives signals from the start sensor, the encoder and the infrared sensor or the photo sensor at the start receiving unit 510, the signal receiving unit 520 and the infrared receiving unit 530, respectively, to calculate information, To the signal transmitter 540.

5, the sensor controller may include a start receiving unit 510, a signal receiving unit 520, an infrared receiving unit 530, and a processor (not shown). The start receiving section 510 can receive the start signal and the start speed from the start sensor at the start of the ride. In response to receiving the start signal, the processor may generate a reproduction signal for reproducing the virtual reality contents and transmit the reproduction signal to the control signal transmission unit 540. For example, the playback signal may include an initial playback speed and / or playback position of the virtual reality content.

The signal receiving unit 520 may receive an encoder signal from an encoder (for example, a magnetic encoder) and calculate a moving speed and a moving distance (position relative value) of the carrier after the sensing count. In addition, the infrared receiver 530 may receive the reflected infrared signal through the absolute position display unit (not shown), calculate the sensing count, and then analyze the inherent code to calculate the current position (absolute position value) of the carrier. The processor compares the error between the travel distance (relative position value) of the ride and the current position (absolute position value) of the carrier, and compares the difference between the section speed and the section speed increase / decrease value Can be calculated. The received and / or calculated information may be at least partially processed in the processor to be generated as a control signal for controlling the virtual reality content, and then transmitted to the control signal transmitter 540.

In some embodiments, the sensor controller may determine the playback speed of the virtual reality content based on the velocity calculated from the encoder signal received at the signal receiver 520. [ Thereafter, the error between the current position (absolute position value) of the carrier detected from the infrared signal received by the infrared receiver 530 and the movement distance (position relative value) calculated from the encoder signal is compared, and the section speed increase / The reproduction speed of the contents can be corrected by increasing or decreasing the reproduction speed of the virtual reality contents. For example, if the position relative value in each section is larger than the absolute position value, the reproduction speed of the virtual reality contents can be reduced.

FIG. 6 illustrates an exemplary ride system 600 arranged in accordance with at least some embodiments described herein. The riding system 600 of Fig. 6 can refer to the basic configuration of the riding system as a whole by referring to the description relating to Fig. 1 to Fig.

The ride sensor controller 640 may include a start receiver 641, a signal receiver 642, an infrared receiver 643, an infrared transmitter 644, a processor 645 and a control signal transmitter 647. The processor 645 may be communicatively coupled to the start receiving unit 641, the signal receiving unit 642, the infrared receiving unit 643, the infrared transmitting unit 644, and the control signal transmitting unit 647. The start receiving section 641 receives the start signal and the start speed from the start sensor and transmits it to the processor 645. The processor 645 can generate a reproduction signal for reproducing the virtual reality contents stored in the HMD 650 from the start signal. The signal receiving unit 642 receives an encoder signal related to the positional relative value of the ride from the encoder 620 and transmits it to the processor 645. [ The processor 645 may cause the infrared transmitter 644 to transmit an infrared signal toward the absolute position display 630. [ The absolute position indicator 630 is formed to be at least partially reflectable. The reflective portion of the absolute position display portion 630 reflects the infrared signal received from the infrared transmitter 644 and transmits it to the infrared receiver 643. The infrared receiver 643 receives the reflected infrared signal related to the absolute position of the ride from the absolute position display 630 and transmits the reflected infrared signal to the processor 645. The processor can generate control signals (or reproduction signals) from the respective information by processing the information on the reproduction and reproduction speed control of the virtual reality contents as described above.

The control signal transmitting unit 647 may receive the reproduction signal or the control signal from the processor 645 and may transmit the virtual reality contents to the HMD 650 capable of storing and displaying the virtual reality contents. For example, the control signal may be transmitted from the control signal transmitting unit 647 to the HMD 650 in a Bluetooth manner. The HMD 650 may include devices that are mounted on a user's head as various types of devices to be developed, either now or in the future, to provide the user with visual and / or auditory as well as other stimuli for experience with other virtual reality content. Basically, currently widely used HMD 650 can provide video and audio data to the user.

FIG. 7 illustrates a block diagram of a process for controlling the playback speed of virtual reality content associated with an exemplary ride, arranged in accordance with at least some embodiments described herein. The process of FIG. 7 may be implemented using, for example, the ride system discussed in FIG. The exemplary process may include one or more actions, acts or functions illustrated by one or more of the blocks S2, S4, S6, S8, S10, S12 and / or S14. Although shown as separate blocks in FIG. 7, various blocks may be divided into additional blocks, combined into fewer blocks, or removed, depending on the required implementation.

Processing may begin at block S2 " receive the encoder signal from an encoder coupled to one or more wheels of the ride ". At block S2, a module of a computing device, processor, or computing device may receive an encoder signal. The encoder may be a magnetic encoder. An encoder may generate an encoder signal by detecting rotation of one or more wheels.

Processing may continue at block S2 with block 4 " transmit an infrared signal toward a plurality of absolute position indicators capable of reflecting infrared rays ". In block S4, a module of a computing device, processor, or computing device may be configured to transmit an infrared signal toward a plurality of absolute position indicators capable of reflecting infrared radiation. The plurality of absolute position indicating portions may be spaced apart from each other on a trajectory that induces movement of the ride. The plurality of absolute position indicating portions may be spaced apart from each other at regular intervals on the track. The plurality of absolute position indicating portions may have unique data values. In the first embodiment, the plurality of absolute position indicating portions may include a high-luminance reflecting bar including a reflecting portion and a non-reflecting portion. In the second embodiment, the plurality of absolute position indicating portions may include a mirror reflector.

Processing may continue at block S4 with block S6 " receive reflected infrared signals from a plurality of absolute position indicators. &Quot; In block S6, the computing device, processor, or module of the computing device may receive the reflected infrared signal from the absolute position indicator. In the first embodiment, when the plurality of absolute position indicating portions are the high-luminance reflecting bars including the reflecting portion and the non-reflecting portion, the infrared ray signal reflected by the high-luminance reflecting bar can be received from at least one infrared ray sensor. At least one infrared sensor may correspond to a reflective portion or a non-reflective portion, respectively, of the high-intensity reflective bar. At least one infrared sensor can receive the reflected infrared signal when corresponding to the reflective portion. At least one infrared sensor can not receive an infrared signal when it corresponds to a non-reflective part. In the second embodiment, when the plurality of absolute position indicating portions are mirror reflectors, the infrared signal reflected from the mirror reflector can be received from the photosensor.

Processing may continue at block S6 to block S8 " calculate the position relative value of the ride based on the received encoder signal ". In block S8, the computing device, processor, or module of the computing device may determine the position relative value of the ride based on the received encoder signal. In some examples, the processor may calculate the ride distance of the ride as a position relative value based on the number of revolutions of the wheel in each section.

Processing may continue at Block S8 with block S10 " calculate the absolute position of the ride based on the received infrared signal ". At block S10, a module of a computing device, processor, or computing device may determine the absolute position of the ride based on the received infrared signal. In the first embodiment, when the plurality of absolute position display portions are high luminance reflection bars, the processor expresses the data value as " 1 " when receiving infrared signals from each infrared sensor, . The processor may calculate an absolute position value based on the expressed whole data value. In the second embodiment, when the plurality of absolute position indicators are mirror reflectors, the processor sets the number of counters at the start of the ride to 0 and increases the number of counters by a predetermined value each time the infrared signal is received . The processor may calculate an absolute position value based on the number of counters.

Blocks S2 through S10 are shown in a sequential process in Fig. 7, but the order is not limited thereto. For example, the process of block S10 may be performed before the process of block S8, or the processes of block S8 and block S10 may be performed simultaneously in parallel. Modifications to this process are a matter of choice for those skilled in the art in actual implementation of the present invention.

Processing may continue at block S10 with block S12 " calculate the difference between position relative value and position absolute value ". In block S12, the computing device, processor, or module of the computing device may calculate the difference between the position relative value and the position absolute value. In some examples, the processor may determine if the value obtained by subtracting the position absolute value from the position relative value is greater than or less than zero.

Processing may continue at block S12 with block S14 " generate a control signal that can control the playback speed of the virtual reality content based on the difference ". In block S14, a module of a computing device, processor, or computing device may calculate a relative speed and speed increase / decrease value for each section of the ride, each time the ride receives an infrared signal through the absolute position indicator based on the difference . In some examples, the basic playback speed of the virtual reality content may be the relative speed of the ride calculated from the encoder signal. The processor may generate a control signal that decreases the content reproduction rate in response to determining that the value obtained by subtracting the positional absolute value from the positional relative value is greater than zero. The processor may generate a control signal that increases the content reproduction speed in response to determining that the value obtained by subtracting the absolute position value from the position relative value is less than zero.
