Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a bodily sensation device that gives a subject a motion corresponding to a video to experience a simulated experience and a method of generating a motion signal to be provided to the bodily sensation device.
[0002]
[Prior art]
In recent years, virtual reality technology has been developed, and a bodily sensation device has been developed which allows a subject to show various images and gives a motion corresponding to the image to the subject to experience a simulated experience.
[0003]
As this kind of bodily sensation device, for example, there is a device installed in an amusement facility. This bodily sensation device includes boarding means for riding a subject, video display means for showing an image to the subject (that is, a screen and a display), and sound reproducing means for making the subject hear sound (that is, a speaker, for example). And, having a motion drive means to slide the boarding means up, down, left and right and back and forth in accordance with the image or to partially vibrate, and to put the subject on the boarding means, to show the subject a realistic image, While listening to the voice of the subject, the motion driving means is driven to move the boarding means violently up, down, left, right, back and forth, or partially vibrate, thereby allowing the subject to experience a simulated experience.
[0004]
By the way, the motion driving means is driven by a motion signal created in advance, and the motion signal is created by a software developer assuming the motion of the motion driving means and the motion of the subject's inertia with respect to the motion driving means in advance. However, there is a problem that it takes a lot of man-hour to create. In addition, the motion signal is created based on a dedicated video previously produced, and does not correspond to a video such as a general TV broadcast, a movie, and a game. Therefore, the bodily sensation device cannot cope with general TV broadcasts, movies, games, and other images, and thus has a problem of low versatility.
[0005]
In order to solve such a problem (that is, to reduce the number of steps for creating a motion signal and to increase the versatility of a motion signal), a region having motion (hereinafter referred to as a motion image) is extracted from a video. A bodily sensation device provided with "motion image detecting means" for detection has been considered (for example, see Patent Document 1).
[0006]
The bodily sensation device of Patent Literature 1 determines, for example, the direction of movement of a moving image, and moves the boarding means up, down, left, right, front, or back in accordance with the determined movement. Specifically, if the motion image is spread radially, it is determined that the direction of the motion is “forward”, and the boarding means is moved forward.
[0007]
Such a bodily sensation device of Patent Literature 1 drives a motion driving unit based on actual measurement values such as a moving image and others (such as voices and movements of a subject) instead of a motion signal created in advance. Therefore, the number of software development steps for creating a motion signal can be significantly reduced. Further, the sensation device of Patent Document 1 does not depend on a motion signal created in advance, so that versatility can be improved.
[0008]
However, with respect to such a bodily sensation device of Patent Document 1, it is assumed that simply controlling the motion drive of a vehicle based on a motion image does not provide a realistic motion. A driving sensation device has also been considered (for example, see Patent Document 2).
[0009]
The sensation device of Patent Literature 2 classifies a video into three parts, a “peripheral part”, a “central part”, and a “lower part”, and moves in a priority order of “peripheral part” → “central part” → “lower part”. By driving the motion driving means in accordance with the portion where the image size is large, it is possible to obtain a realistic motion (no more than the bodily sensation device of Patent Literature 1) regardless of what kind of video is used.

[Patent Document 2]
JP 2001-183968 A (paragraphs 19 to 54, FIGS. 1 to 4)
[0011]
[Problems to be solved by the invention]
However, since images such as general TV broadcasts and movies are not produced on the assumption that a motion driving unit is driven, camera angles are diversified. For this reason, all of the above-described conventional technologies have a problem that only a motion with a poor sense of reality can be obtained.
[0012]
In addition, the conventional technique has a problem that when the viewing time is long in a movie or the like, the subject is easily fatigued when the motion driving unit is continuously driven from the beginning to the end of the main part.
[0013]
[Means for Solving the Problems]
In order to solve the above-described problem, a bodily sensation device according to the present invention is a bodily sensation device that gives a motion corresponding to a video to a subject to experience a simulated experience. Is detected, and a motion is given to the subject according to the acceleration of the image.
[0014]
Accordingly, the bodily sensation device according to the present invention can be used for general TV broadcasts, movies, and other images (especially images with various camera angles) that are not produced on the assumption that the motion driving unit is driven. Even so, a realistic motion can be given to the subject according to the scene of the video.
[0015]
Also, in a bodily sensation device according to another invention, in a bodily sensation device that gives a subject a motion corresponding to a video to experience a simulated experience, the video is compared with data serving as a reference for determining a scene type of the video. By doing so, a motion is given to the subject only when it is determined that it is effective to give the motion to the subject.
[0016]
Thereby, the bodily sensation device according to the other invention does not move the subject as it is in accordance with the motion of the image, but moves the subject only when it is determined that it is effective to move the subject. give. Therefore, the subject does not slide / vibrate in unnecessary scenes, so that the subject can be hardly tired.
[0017]

FIG. 7 is a diagram showing an example of table data for generating a motion signal. FIG. 8 is a diagram showing an example of the control table data of the motion driving means.
[0029]
(Operation of control unit)
As shown in FIG. 2, in step (hereinafter, referred to as S) 101, the video storage unit 103 of the control unit 100 fetches the video signal from the video supply unit 101 and stores the video signal in a predetermined number of frames (at least three frames) Accumulate by the above. Here, the reason why the number of frames to be stored is at least three or more is to enable the video acceleration detecting means 105 to detect the video acceleration in S103.
[0030]
Next, in S103, the video acceleration detection means 105 of the control unit 100 detects the acceleration of the video from the video stored in the video storage means 103. For example, as shown in FIG. 3, the image is divided into a plurality of regions, and a luminance movement vector (i.e., a luminance moving amount and direction) for each pixel is detected in each region, and this is detected. And extract as a motion vector of each area. This is performed over a predetermined number of frames or more (at least three frames), and the acceleration of the video is detected from the amount of change in the motion vector of each area. FIG. 3 shows an example in which a video is divided into a plurality of regions, and two regions 301 and 303 among the regions are exemplified. In the two regions 301 and 303, a thin arrow indicates a luminance movement vector for each pixel, and a thick white arrow indicates a motion vector of each region. Note that the starting point of the thick white arrow is the center of gravity of the entire thin arrow (that is, the movement vector of luminance for each pixel).
[0031]
Next, in S105, the audio detection unit 107 of the control unit 100 takes in the audio signal from the video supply unit 101, and detects the audio to be reproduced by the audio reproduction unit 163.
[0032]
Next, in S107, the scene type determination means 111 of the control unit 100 determines the scene type of the video (that is, what kind of scene the video is) from the detection results in S103 and S105. This is performed as follows. That is, the scene database 109 previously holds the table data for scene determination described above. The table data for scene determination includes, for example, as shown in FIG. 4, a parameter of “change of direction / angle of frame” in a video, a parameter of “change of motion of person / object” in video, and a parameter of A parameter of "size", a parameter of "tempo" of the sound, and a code for specifying a scene type (hereinafter, referred to as a scene type code) are linked. The scene type determination unit 111 obtains information on the acceleration of the video detected by the video acceleration detection unit 105 (hereinafter referred to as video acceleration information) and the information on the audio detected by the audio detection unit 107 (hereinafter referred to as audio information). With reference to the table data for scene determination held in the scene database 109, a scene type matching the video acceleration information and the audio information is specified. Thus, the scene of the video is determined.
[0033]
For example, if the scene is a viewpoint from a vehicle-like vehicle, the image spreads radially and continuously accelerates left and right repeatedly. At this time, the sound is a certain level or more, and a noise-like engine sound continues. The scene type determination unit 111 determines that the scene is a viewpoint from a vehicle-like vehicle by specifying a scene type code corresponding to such a condition.
[0034]
When the scene is a viewpoint from a roller coaster-like vehicle, the image spreads radially and accelerates up and down in addition to continuously accelerating left and right. At this time, the sound is a certain level or more, and a noise-like engine sound continues. The scene type determining means 111 determines that the scene is a viewpoint from a roller coaster-like vehicle by specifying a scene type code corresponding to such a condition.
[0035]
Further, when the scene is a viewpoint from a third party, the video has little movement on the entire screen. The scene type determination unit 111 determines that the scene is not a viewpoint from the subject 200 but a viewpoint from a third party by specifying a scene type code corresponding to such a condition.
[0036]
The scene type determining means 111 determines a scene in this way.
[0037]
Next, in S109, the motion drive control unit 113 of the control unit 100 generates a motion signal based on the determination result in S107.
[0038]

[0039]
The operation of the motion drive control means 113 in S109 and S111 will be described in detail in the section "Operation of the motion drive control means" described later.
[0040]
(Operation of the motion drive control means)
Hereinafter, the operation of the motion drive control unit 113 will be described. Note that the following operations of S151 to S163 in FIG. 5 correspond to the operations of S109 in FIG. 2, and the operations of S165 correspond to the operations of S111 in FIG.
[0041]
In S109 of FIG. 2, the motion drive control unit 113 of the control unit 100 receives the determination result of S107 from the scene type determination unit 111, and generates a motion signal based on the determination result of S107.
[0042]
At this time, as shown in S151 of FIG. 5, the motion drive control unit 113 determines whether or not it is the viewpoint of the party (subject 200) based on the determination result of S107 received from the scene type determination unit 111. I do. Here, if the motion drive control unit 113 determines that the viewpoint is that of the party (subject 200), the operation proceeds to S153. If the motion drive control unit 113 determines that the viewpoint is not the viewpoint of the subject (the subject 200), the operation shifts to S163.
[0043]
In S153, the motion drive control unit 113 determines whether the video is a scene that is effective for motion drive. Here, when the motion drive control unit 113 determines that the video is a scene that is effective for motion driving, the operation proceeds to S155, and when it determines that the video is a scene that is not effective for motion drive, , The operation proceeds to S163.
[0044]
In S155, the motion drive control unit 113 calculates the image acceleration area. The image acceleration area is an area of a region where an image is divided into a plurality of regions and adjacent regions have the same acceleration vector. For example, as shown in FIG. 6, the image acceleration area is the area of each of regions 401, 403, 405, and 407 indicated by four types of hatching when the image is radially spread in four directions.
[0045]
In S157, the motion drive control unit 113 compares each image acceleration area (for example, four image acceleration areas in the example shown in FIG. 6).
[0046]
In S159, the motion drive control unit 113 generates a motion signal as follows. That is, the motion drive control unit 113 specifies the region having the largest image acceleration area (the region 401 in the example of FIG. 6), and changes the acceleration at which the pixel moves or the luminance of the pixel in the region having the largest image acceleration area. Detect acceleration. Then, the motion drive control unit 113 refers to, for example, table data for generating a motion signal held in the scene database 109 as shown in FIG. The motion signal corresponding to the acceleration at which the pixel moves in the region having the largest image acceleration area or the acceleration at which the luminance of the pixel changes is specified. The table data for generating a motion signal shown in FIG. 7 includes “scene type code” and “acceleration (here,“ large ”,“ medium ”,“ small ”) divided into three sections by a predetermined threshold. , An acceleration at which the pixel moves in the area or an acceleration at which the luminance of the pixel changes) is linked to the “motion signal”. The motion drive control unit 113 specifies the motion signal with reference to the table data for generating the motion signal, and generates a corresponding motion signal.
[0047]
The motion signal is linked to the drive amount of each drive unit (the drive units 1 to 6 in the example shown in FIG. 8) of the motion drive unit 173 according to the control table data of the motion drive unit 173 shown in FIG. Can be In the example shown in FIG. 8, the drive amount is shown in four stages of 1 to 4. Here, “1” indicates “strong”, “2” indicates “somewhat strong”, “3” indicates “somewhat weak”, and “4” indicates “weak”.
[0048]
In S161, the motion drive control unit 113 determines whether the motion signal generated in S159 is within the drive limit of the motion drive unit 173. Here, when the motion drive control unit 113 determines that the motion signal generated in S159 is within the drive limit of the motion drive unit 173, the operation shifts to S165, and the motion signal generated in S159 is If it is determined that the driving limit of 173 is reached, the operation moves to S163.
[0049]
In S163, the motion drive control unit 113 generates a motion signal corresponding to an amount serving as a drive limit of the motion drive unit 173.
[0050]
In S165, the motion drive control unit 113 outputs the motion signal generated in S159 or S163 to the motion drive unit 173.
[0051]
The bodily sensation device according to this embodiment described above is a video such as a general TV broadcast or a movie that is not produced on the assumption that the motion driving unit is driven (especially, a video having various camera angles). ) Can give the subject a realistic movement according to the scene of the video.
[0052]
In addition, the bodily sensation device according to this embodiment does not move the subject as it is in accordance with the motion of the video, but only moves the subject when it is determined that it is effective to move the subject. give. Therefore, the subject does not slide / vibrate in unnecessary scenes, so that the subject can be hardly tired.
[0053]
<Second embodiment>
In the first embodiment, the motion drive control unit 113 determines whether the video is a scene that is effective for motion drive (see S153 in FIG. 5). On the other hand, in this embodiment, whether or not the motion driving unit 173 is driven is linked in advance to the control table data of the motion driving unit, and the motion driving unit 173 is used by using the control table data of the motion driving unit. Is controlled.
[0054]
Hereinafter, the second embodiment will be described with reference to FIG. FIG. 9 is a diagram showing an example of the control table data of the motion driving means.
[0055]
In S109 of FIG. 2, the motion drive control unit 113 of the control unit 100 receives the scene type code, which is the determination result of S107, from the scene type determination unit 111.
[0056]
The scene type code is determined based on, for example, whether or not the motion driving unit 173 is driven, and each driving unit of the motion driving unit 173 (the driving unit in the example illustrated in FIG. 9) based on the control table data of the motion driving unit 173 illustrated in FIG. The link is linked with the drive amount of the units 1 to 6). In the example shown in FIG. 9, whether the motion driving unit 173 is driven is indicated by ON / OFF. Here, it is assumed that “ON” indicates “driving” and “OFF” indicates “no driving”. Further, in the example shown in FIG. 9, the driving amount is shown in four stages of 1 to 4. Here, "1" indicates "strong", "2" indicates "slightly strong", "3" indicates "slightly weak", "4" indicates "weak", and "-" indicates "do not drive". I do.
[0057]
The motion drive control unit 113 refers to the scene type code received from the scene type determination unit 111 and the table data shown in FIG. 9 to refer to each of the driving units (the driving units 1 to 6 in the example shown in FIG. 9). The driving amount is specified, and the motion driving unit 173 is controlled based on the specified driving amount.
[0058]
In the bodily sensation device 1 according to the embodiment described above, since the motion drive control unit 113 does not need to determine whether or not the scene is effective for motion drive, the motion supply control unit 113 supplies the video after the video supply unit 101 supplies the video. The time until the driving unit 173 is driven can be reduced.
[0059]
<Appendix>
The present invention is not limited to the above embodiment, and various applications and modifications can be considered without departing from the gist of the present invention.
[0060]
For example, the form of various signals and table data can be arbitrarily changed.
[0061]
Further, S103 and S107 in the first embodiment can be reversed.
[0062]
Further, in the first and second embodiments, the video acceleration detecting means 105 detects the video acceleration from the moving amount of the luminance of the pixel. However, the original data of the video is compressed by a method such as MPEG. In this case, since the motion vector data is embedded in the video data in advance, the motion vector embedded in the video data may be used. In this case, since there is no need to calculate a motion vector, motion drive control can be performed in a short time.
[0063]
