Description

  The present invention relates to a pseudo ring throwing game apparatus using a display device and related technology.

  Patent Document 1 discloses a ring throwing equipment that can increase the hit rate when a person with poor vision or weak arm power, such as a severely disabled person, an infant, or an elderly person, plays a ring throwing game. .

JP 2004-329799 A

  However, even when the physical function is reduced, such as elderly people, there are various degrees, and there are some people who can throw a throw ring and others who can not. Therefore, the ring throwing toy described above may not be supported. By the way, although it is not the prior art, the lasso can be lightened, but there is a limit to the lightness. This is because if there is no weight, the lasso will not fly as intended.

  Further, in the above-described ring throwing play equipment, when the game is played again after the game is finished, it is necessary to collect the throwing ring, and such a collection also has a heavy burden on a person whose physical function has deteriorated. Of course, there is no problem when the caregiver performs such collection, but there may be no caregiver. Even if there are many people who are cared for, they may not be able to turn their hands. By the way, in elderly welfare facilities, the shortage of caregivers has become a social problem, and the placement of many caregivers is often difficult.

  Therefore, the purpose of the present invention is to reduce the physical burden during play of people whose physical functions have deteriorated, such as elderly people, and in turn, the pseudo ring throwing game apparatus that can also reduce the burden on the assistants such as caregivers and related items. Is to provide technology.

  According to the aspect of the present invention, the pseudo ring-throw game apparatus is a pseudo-ring-throw game apparatus that is used by being connected to a display device, and includes an imaging unit that images a subject operated by a user, a throw ring object, and a target object. Is displayed on the display device, the movement of the subject is detected based on the image of the subject obtained by the imaging, and the movement of the lasso object is controlled based on the detection result; And a processor that executes a hit determination between the lasso object and the target object.

  According to this configuration, the user can enjoy the ring-throwing game simply by moving the subject. In this case, the user can experience a more realistic feeling by performing an action of throwing a subject (not actually throwing) as if he / she actually throws a ring.

  In addition, since the user does not need to actually throw the lasso, the subject corresponding to the lasso can be created with a lighter object as much as possible, and it is not necessary to collect the lasso. Therefore, it is possible to reduce the physical burden at the time of play for people whose physical functions are reduced, such as the elderly, and thus the burden on the assistant such as a caregiver can be reduced.

  Furthermore, since the user aims at the target object by adjusting the speed and position of moving the subject, an improvement in concentration can be expected. In addition, since the user operates the subject in the air without touching the screen, a new brain function can be expected to be activated by space recognition.

  In this pseudo ring throwing game device, the target object includes at least a plurality of targets arranged so as to extend in the back of the screen of the display device, and the processor has a first axis (corresponding to the X axis in the embodiment) and In accordance with the position of the subject in the first axis direction of the subject in a two-dimensional orthogonal coordinate system having a second axis (corresponding to the Y axis in the embodiment) orthogonal to the first axis as a coordinate axis, When the velocity vector in the second axis direction of the subject is in a predetermined direction along the second axis and the magnitude of the velocity vector exceeds a predetermined value, the throwing The wheel object is moved toward the back of the screen of the display device, and the predetermined direction along the second axis corresponds to the direction toward the back of the screen of the display device.

  According to this configuration, by setting the first axis in the horizontal direction, the user can adjust the horizontal position of the lasso object by moving the subject in the horizontal direction.

  In this pseudo ring throw game device, when the processor moves the throw ring object toward the back of the screen of the display device, the processor skips the ring throw image according to the magnitude of the velocity vector exceeding the predetermined value. Determine the distance.

  According to this configuration, the user can adjust the flying distance of the lasso object by adjusting the speed of the subject.

  In the pseudo ring throwing game apparatus, when the processor moves the throwing ring object toward the back of the screen of the display device, the processor does not take the direction of the velocity vector into consideration, and based on the horizontal position of the throwing ring object. The horizontal position of the lasso object that moves toward the back of the screen of the display device is determined.

  According to this configuration, after determining the horizontal position of the lasso object, the user can focus only on the speed at which the subject is moved, and the difficulty level can be reduced.

  Further, in the pseudo ring toss game device, when the processor moves the lasso object toward the back of the screen of the display device, the processor moves toward the back of the screen of the display device according to the direction of the speed vector. It is also possible to determine the direction of the lasso object.

  According to this configuration, the user can adjust the direction in which the lasso object flies by adjusting the direction in which the subject is moved.

  In the above pseudo ring throw game device, the subject is a retroreflector that retroreflects light.

  According to this configuration, since the subject retroreflects light, the subject image appears more clearly in the captured image, and the subject image can be extracted with higher accuracy.

  In this pseudo ring throw game device, the imaging means includes a light emitting means for intermittently irradiating light.

  According to this configuration, it is possible to take a difference between captured images when light is irradiated and when not irradiated, and images other than the subject image (reflected light from the subject) (light from light sources other than the subject) That is, noise can be easily removed.

  In this pseudo ring throwing game device, the light emitted by the light emitting means is infrared light.

  According to this configuration, for example, by imaging only infrared light through an infrared filter, light other than infrared light can be easily removed.

  In the pseudo ring-throw game device, the subject is attached or held to a user's hand.

The adapter 1 supplies the video signal VD generated by the multimedia processor 33 to the AV cable 13 as it is, and also amplifies the audio signal AU and supplies it to the AV cable 13.

  Returning to FIG. 1, the sensor unit 102 is placed on the floor surface. Therefore, the imaging surface of the image sensor 31 is substantially parallel to the floor surface. A vertical coordinate axis (Y axis) of the image sensor 31 (captured image (difference image)) extends along the longitudinal direction of the sensor unit 102, and a horizontal coordinate axis (X axis) extends perpendicular to the vertical coordinate axis. . The horizontal coordinate axis (X axis) of the image sensor 31 is parallel to the horizontal coordinate axis (x axis) of the three-dimensional space in which the three-dimensional image is arranged. The vertical coordinate axis (Y axis) of the image sensor 31 is parallel to the depth coordinate axis (z axis) of the three-dimensional space. The depth coordinate axis (z axis) is a coordinate axis along the depth direction of the screen displayed on the television monitor 11. The coordinates of the image sensor 31 are represented by capital letters (X, Y), and the three-dimensional coordinates of the three-dimensional space are represented by small letters (x, y, z).

  The user faces the pseudo throwing ring 104 forward (television monitor) over the sensor unit 102 so that the back surface of the pseudo throwing ring 104 faces downward, that is, the retroreflective sheet 124 is photographed by the image sensor 31. 11), that is, throwing in the positive direction of the Y axis is performed (not actually thrown).

  Next, the processing contents of the multimedia processor 33 will be described with reference to the drawing showing the play screen displayed on the television monitor 11 by the multimedia processor 33.

  FIG. 5 is a view showing an example of a play screen displayed on the television monitor 11 of FIG. Referring to FIG. 5, the play screen displayed by multimedia processor 33 includes a difficulty level display unit 155 for displaying the difficulty level and target objects 153LL, 153ML, 153UL, 153LC, 153MC, 153UC, 153LR, 153MR, 153UR (these May be collectively referred to as a target object 153).

  The coordinates of the target objects 153LL, 153LC, and 153LR in the z-axis (depth) direction are the same. The coordinates of the target objects 1153ML, 153MC, and 153MR in the z-axis (depth) direction are the same. The coordinates of the target objects 153UL, 153UC, and 153UR in the z-axis (depth) direction are the same.

  The coordinates of the target objects 153UL, 153ML, and 153LL in the y-axis (horizontal) direction are the same. The coordinates of the target objects 1153UC, 153MC, and 153LC in the y-axis (horizontal) direction are the same. The coordinates of the target objects 153UR, 153MR, 153LR in the y-axis (horizontal) direction are the same.

  The play screen also includes a lasso object 151 that responds to the movement of the retroreflective sheet 124. When the user moves the pseudo lasso 104 horizontally and in the X-axis direction, the lasso object 151 moves left and right (x-axis direction) accordingly. That is, the horizontal coordinate (x coordinate) of the lasso object 151 is set at a position corresponding to the horizontal coordinate (X coordinate) of the retroreflective sheet 124 of the pseudo lasso 104.

  Furthermore, when the user moves the pseudo lasso 104 at a speed exceeding the predetermined value Vt, that is, when the speed based on the vertical coordinate (Y coordinate) of the retroreflective sheet 124 of the pseudo lasso 104 exceeds the predetermined value Vt, The lasso object 151 flies toward the back of the screen (along the z axis). The course (x coordinate) in this case is set to the x coordinate of the lasso object 151 immediately before jumping out, and does not depend on the coordinates of the pseudo lasso 104 thereafter.

  The initial speed when the lasso object 151 flies is proportional to the speed Vy of the retroreflective sheet 124 in the Y-axis direction. Further, the emission angle (elevation angle) θ of the lasso object 151 is determined according to the speed Vy of the retroreflective sheet 124 in the Y-axis direction. For example, a plurality of speed ranges in the Y-axis direction of the retroreflective sheet 124 are set, and an emission angle θ is assigned to each speed range. In this case, the allocation is performed so that the emission angle θ increases as the velocity Vy in the Y-axis direction increases. Therefore, the flying distance of the lasso object 151, that is, the distance in the z-axis direction depends on the speed Vy of the retroreflective sheet 124 in the Y-axis direction. However, when the speed Vy of the retroreflective sheet 124 in the Y-axis direction is equal to or less than the predetermined value Vt, the lasso object 151 does not fly.

  The user first operates the pseudo lasso 104 in the horizontal and X-axis directions to move the lasso object 151 to an appropriate horizontal position (position in the x-axis direction). Then, the user swings the pseudo lasso 104 forward (Y-axis positive direction) to fly the lasso object 151 to the back of the screen and tries to fit the target object 153. When the lasso object 151 is fitted into the target object 153, the number is added to the number display portion 57. In addition, the target object 153 in which the lasso object 151 is fitted is deleted. Note that the user has to shake the pseudo lasso 104 more strongly as the targeted target object 153 is located deeper.

  Here, when the lasso object 151 flies while the center position of the lasso object 151 is in the range RC, it is thrown to any of the target objects 153UC, 153MC, or 153LC if the flying distance is appropriate. A ring object 151 fits. When the lasso object 151 flies while the center position of the lasso object 151 is in the range RL, if the flying distance is appropriate, the lasso object 151 is set to one of the target objects 153UL, 153ML, or 153LL. Fits. When the lasso object 151 flies while the center position of the lasso object 151 is in the range RR, the lasso object 151 is selected as one of the target objects 153UR, 153MR, or 153LR if the flight distance is appropriate. Fits.

  The multimedia processor 33 fits the lasso object 151 to the target object 153 when the xyz coordinates of the center position of the lasso object 151 are in the target space TS including the target object 153. When the target space TS is expanded, the difficulty level is lowered, and when the target space TS is narrowed, the difficulty level is increased.

  In the present embodiment, three difficulty levels (difficult, normal, easy) are set. When the difficulty level is “easy”, the target space TS is always set larger than when the difficulty level is “difficult”. When the difficulty level is “Normal”, the target space TS is generated with the same probability when the difficulty level is “Easy” and when the difficulty level is “Difficult”. Be controlled. The width of the target space TS in the x-axis direction corresponds to the widths of the ranges RL, RC, and RR.

  Next, the processing flow of the pseudo ring throwing game system will be described using a flowchart.

  FIG. 6 is a flowchart showing the flow of overall processing by the multimedia processor 33 of FIG. Referring to FIG. 6, in step S <b> 1, multimedia processor 33 displays a screen on television monitor 11 for the user to select a difficulty level (difficult, normal, easy). In step S3, the multimedia processor 33 displays a screen for explaining the rules on the television monitor 11. In step S5, the multimedia processor 33 displays a play screen on the television monitor 11 (see FIG. 5). In step S7, the multimedia processor 33 displays a result screen including the user's evaluation.

  FIG. 7 is a flowchart showing the flow of the play screen display process in step S5 of FIG. Referring to FIG. 7, in step S21, multimedia processor 33 updates the play screen (see FIG. 5) according to the results of previous steps S25 and S27. In step S <b> 23, the multimedia processor 33 acquires the coordinates (X, Y) of the pseudo throwing ring 104 from the sensor unit 102. In step S <b> 25, the multimedia processor 33 controls the lasso object 151 on the screen based on the coordinates (X, Y) of the pseudo lasso 104. In step S <b> 27, the multimedia processor 33 determines whether or not the lasso object 151 is fitted on the target object 153. In step S29, the multimedia processor 33 determines whether or not the throwing object 151 has been thrown nine times. If “NO”, the multimedia processor 33 returns to step S21 to update the play screen, and returns “YES”. To do.

  FIG. 8 is a flowchart showing the flow of the lasso object control process in step S25 of FIG. Referring to FIG. 8, in step S51, the multimedia processor 33 determines whether or not the lasso object 151 has been thrown, and proceeds to step S63 if "YES", and proceeds to step S53 if "NO". move on.

  In step S <b> 53, the multimedia processor 33 calculates the X component Vx and the Y component Vy of the velocity vector of the pseudo lasso 104 based on the coordinates (X, Y) of the pseudo lasso 104 acquired from the sensor unit 102. In step S55, the multimedia processor 33 determines whether or not the Y component Vy exceeds the predetermined value Vt. If the Y component Vy exceeds the predetermined value Vt, the process proceeds to step S57. Proceed to S69.

  In step S 69, the multimedia processor 33 updates the horizontal coordinate (x coordinate) xr of the lasso object 151 based on the X component Vx of the velocity vector of the pseudo lasso 104. In step S71, the multimedia processor 33 sets the vertical coordinate (y coordinate) of the lasso object 151 to a predetermined value. This is because the vertical coordinate is fixed before the lasso object 151 is thrown.

  On the other hand, in step S57, the multimedia processor 33 calculates the z component vz0 of the initial velocity vector of the lasso object 151 based on the Y component Vy of the velocity vector of the pseudo lasso 104. In step S59, the multimedia processor 33 determines the emission angle θ of the lasso object 151 based on the Y component Vy of the velocity vector of the pseudo lasso 104. The method for determining the emission angle θ is as described above. In step S61, the multimedia processor 33 calculates the y component vy0 of the initial velocity vector of the lasso object 151 based on the z component vz0 and the exit angle θ of the initial velocity vector of the lasso object 151.

  After “YES” is determined in step S51 or after step S61, in step S63, the multimedia processor 33 determines the lasso object 151 based on the z component vz0 of the initial velocity vector of the lasso object 151. The depth coordinate (z coordinate) zr is calculated. In this case, air resistance can also be considered. In step S65, the multimedia processor 33 calculates the vertical coordinate (y coordinate) yr of the lasso object 151 based on the y component vy0 of the initial velocity vector of the lasso object 151. In this case, gravitational acceleration is taken into account. In step S67, the multimedia processor 33 sets the horizontal coordinate (x coordinate) xr of the lasso object 151 to the previous horizontal coordinate (x coordinate) xr.

  FIG. 9 is a flowchart showing the flow of the hit determination process in step S27 of FIG. Referring to FIG. 9, in step S101, the multimedia processor 33 determines whether or not the lasso object 151 has been fitted to the target object 153. If it is fitted, the process proceeds to step S109. If not, the multimedia processor 33 proceeds to step S109. The process proceeds to S103.

  Here, the determination (whether or not) whether or not the lasso object 151 is fitted to the target object 153 depends on whether or not the xyz coordinate of the center of the lasso object 151 is in the target space TS as described above. Determined. The target space TS is set according to the difficulty level set in step S1 of FIG.

  In step S109, the multimedia processor 33 increases the number of the number display unit 57 by one. In step S111, the multimedia processor 33 performs display setting indicating success and returns. On the other hand, in step S103, the multimedia processor 33 determines whether or not the determination in step S101 has been completed for all target objects 153. If completed, the process proceeds to step S105. Returns to step S101. In step S105, the multimedia processor 33 determines whether or not the lasso object 151 has landed, returns if not landed, and proceeds to step S107 if landed. In step S107, the multimedia processor 33 performs display setting indicating failure and returns.

  FIG. 10 is a flowchart showing the flow of overall processing by the MCU 131 of FIG. Referring to FIG. 10, in step S201, the MCU 131 lights up the infrared light emitting diode 108. In step S <b> 203, the MCU 131 acquires image data when the infrared light is lit from the image sensor 31 and stores the image data in the internal memory.

  In this embodiment, a CMOS image sensor of 32 pixels × 32 pixels is used as an example of the image sensor 31. Therefore, pixel data of 32 pixels × 32 pixels is output from the image sensor 31 as image data. This pixel data is converted into digital data and stored as elements of a two-dimensional array P1 [X] [Y] on the internal memory.

  In step S205, the MCU 131 turns off the infrared light emitting diode 108. In step S207, the MCU 131 acquires image data (32 pixel × 32 pixel data) when the infrared light is extinguished from the image sensor 31, and stores it in the internal memory. In this case, the pixel data is stored as an element of the two-dimensional array P2 [X] [Y] on the internal memory.

  The flash photography is performed as described above. Here, in the two-dimensional coordinate system representing the position of each pixel constituting the image by the image sensor 31, the horizontal direction is the X axis and the vertical direction is the Y axis. One pixel is taken as one unit of coordinate values. In this embodiment, since the image sensor 31 of 32 pixels × 32 pixels is used, X = 0 to 31 and Y = 0 to 31. The same applies to the difference image. The pixel data is a luminance value.

  In step S209, the MCU 131 causes pixel data when the infrared light emitting diode 108 is turned on (that is, an element of the array P1 [X] [Y]) and pixel data when the infrared light emitting diode 108 is turned off (that is, the array P2 [ The difference pixel data is stored as an element of the two-dimensional array Dif [X] [Y].

  Here, the elements of the array P1 [X] [Y] (that is, pixel data at the time of lighting) are the pixel data P1 [X] [Y], and the elements of the array P2 [X] [Y] (that is, pixel data at the time of turning off). May be expressed as pixel data P2 [X] [Y], and an element of the array Dif [X] [Y] (that is, difference pixel data) may be expressed as difference pixel data Dif [X] [Y].

  In step S211, the MCU 131 extracts difference pixel data indicating the maximum luminance value from all the difference pixel data Dif [X] [Y] obtained in step S209. In step S213, the MCU 131 compares the maximum luminance value with a predetermined threshold Th. If the maximum luminance value is larger than the predetermined threshold Th, the MCU 131 uses the pixel having the maximum luminance value as the current attention point. The process proceeds to S215, and otherwise, the process proceeds to step S217 assuming that there is no current attention point.

  Here, when the retroreflective sheet 124 is reflected in the difference image, the luminance value of the portion is larger than that of the other portion, and therefore, the pixel having a luminance value exceeding the predetermined threshold Th determined empirically. The region is an image of the retroreflective sheet 124. Of the pixels forming the image, the pixel having the maximum luminance value is set as the attention point of the retroreflective sheet 124.

  In step S215, the MCU 131 substitutes the X coordinate and Y coordinate of the pixel having the maximum luminance value into variables Xc and Yc, respectively. On the other hand, if there is no current attention point, the MCU 131 assigns 0 to the variables Xc and Yc in step S217.

  In step S219, the MCU 131 drives the infrared light emitting diode 133 for communication and transmits the coordinates (Xc, Yc) of the target point to the IR receiver 141 of the adapter 1. At this time, the MCU 131 also sends operation signals for the switches 114, 116, 118, and 120 to the adapter 1. The MCU 131 returns to step S201 after step S219. The MCU 131 repeats the processing of steps S201 to S219, and transmits the coordinates (Xc, Yc) of the attention point of the moving retroreflective sheet 124 based on the strobe shooting to the adapter 1.

  As described above, according to the present embodiment, the user can enjoy the ring-throwing game simply by holding the pseudo throwing ring 104 in his hand. In this case, the user can experience a more realistic feeling by performing the operation of throwing the pseudo lasso 104 (not actually throwing) as if performing an actual ring throw.

  Here, the case where people with reduced physical functions such as elderly people use general lasso playground equipment will be examined. Even when the physical function is reduced, such as elderly people, there are various degrees, and there are some people who can throw an actual lasso and others who cannot. Therefore, a general ring throwing play equipment may not be able to deal with more people. By the way, you can lighten the lasso, but there is a limit to how light it can be. This is because if there is no weight, the lasso will not fly as intended.

  Further, in a general ring-throwing play equipment, when playing again after the game, it is necessary to collect the throwing ring, and such collection also has a heavy burden on a person whose physical function has deteriorated. Of course, there is no problem when the caregiver performs such collection, but there may be no caregiver. Even if there are many people who are cared for, they may not be able to turn their hands. By the way, in elderly welfare facilities, the shortage of caregivers has become a social problem, and the placement of many caregivers is often difficult.

  According to the present embodiment, since the user does not need to actually throw the pseudo lasso 104, the pseudo lasso 104 can be made as light as possible. Incidentally, as described above, the pseudo lasso 104 is made of a light material. Further, since the pseudo lasso 104 is not actually thrown, it is not necessary to collect it. Therefore, it is possible to reduce the physical burden at the time of play for people whose physical functions are reduced, such as the elderly, and thus the burden on the assistant such as a caregiver can be reduced.

  Furthermore, since the user aims at the target object 153 by adjusting the speed and position of moving the dummy throwing ring 104, an improvement in concentration can be expected. In addition, since the user operates the pseudo lasso 104 in the air without touching the screen, a new brain function can be expected to be activated by space recognition.

  Furthermore, the user can adjust the horizontal position of the lasso object 151 by moving the pseudo lasso 104 in the horizontal and X-axis direction. Further, the user can adjust the flying distance of the lasso object 151 by adjusting the speed at which the pseudo lasso 104 is swung. Further, since the course (x coordinate) along which the lasso object 151 flies does not depend on the X coordinate of the subsequent pseudo lasso 104, the user can determine the horizontal position of the lasso object 151 after determining the horizontal position. Only the strength of shaking 104 can be focused, and the difficulty level can be lowered.

  The present invention is not limited to the above-described embodiment, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.

  (1) In the embodiment, the pseudo throw ring 104 is used as an input device in order to enhance the sense of reality, but a glove 7R shown in FIG. 11 can also be used. As shown in FIG. 11, a retroreflective sheet 9R is attached to the hand of the globe 7R on the flat side. In addition, for example, an input device that is attached with a retroreflective sheet and that is held by hand can also be used. In addition, for example, for people who can move their hands if they can move other parts of the body, although not shown, if they can move their feet, sock-type input devices with retroreflective sheets attached, if their heads can move For example, a headband type input device to which a retroreflective sheet is attached can be used. In any case, the form of the input device is not limited as long as the surface on which the subject such as the retroreflective sheet is provided can be moved in front of the imaging unit.

  (2) The number and location of the target objects 153 can be set arbitrarily. In addition, the direction (x component) of the initial velocity vector of the lasso object 151 when flying can be determined in consideration of the direction (x component) of the velocity vector of the pseudo lasso 104. This increases the difficulty level.

  (3) The above flash photography (blinking of the infrared light emitting diode 108) and the difference processing are only a preferable example and are not essential elements of the present invention. That is, the infrared light emitting diode 108 may not be blinked, and the infrared light emitting diode 108 may not be provided. Irradiation light is not limited to infrared light. Further, the retroreflective sheet 124 is not an essential element of the present invention, and it is only necessary to analyze a captured image and detect an input device (for example, a pseudo-ring) or a specific part of the body (for example, a hand). The image sensor is not limited to an image sensor, and other image sensors such as a CCD can be used.
