Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for decoding the form of a body part representing a certain intention (a form of intention display of a body part) by a computer to identify the type of the intention display, and furthermore, the technique for identifying the identified intention The present invention relates to a technique in which a display type is compared with another type of intention display by a computer to evaluate / determine the superiority between the two types of intention display.

[0002] That is, the present invention takes a form of a body part expressing a certain intention (a form of intention display of a body part), and changes the form of the intention display based on an identification image obtained by image processing of the captured image. Identifying the type of embodied intention expression, a method of identifying the intention expression form of the body part using a computer, an identification device of the intention expression form for performing the identification method, and the identification method as a main part Competition evaluation methods for various computer games adopted (for example, methods for determining wins and losses and score evaluation), and various computer game apparatuses (for example, Janken game apparatuses and Gesture game device).

[0003]

2. Description of the Related Art It is common to express and communicate desired intentions by changing the form of a body part. Sign language is a typical example, but it is well known that shaking the head vertically means affirmation and shaking the head horizontally means negation. In Janken, the difference in the form of the fingers or the difference in the placement of both feet indicates the willingness to select stones (goo), scissors (choki), paper (par), and sports such as baseball and volleyball. However, it is a sign that conveys various intentions by changing the form of the body part. It is also known that the direction of the fingertip (the direction in which the finger is pointed) is used to indicate the intention of selecting the other party, and that the form in which the thumb of the grip fist is raised expresses a satisfactory (good) intention. Furthermore, sign language hand gestures, dance choreography or steps are also expressions of intention in the form of intention display of the body part.

[0004] On the other hand, there are various games (computer match games) that play against a virtual opponent formed by a computer. Conventionally, however, a method of communicating a player's intention to a virtual opponent formed by a computer (various intentions of the player to the computer) Is a method of inputting a player's intention through a mechanical input device. Even if the intention is easily conveyed by the form of the body part's intention, it can correspond to various intentions Thus, a number of push buttons, foot switches, or mechanical input device players, such as joysticks, provided on computer game devices had to be operated. For this reason, even if the game itself is extremely simple, for example, "rock-paper-scissors-game", it is extremely difficult for an infant player to execute the selection input operation corresponding to "goo", "choki", and "par" accurately and quickly. . In addition, even for an older player, the flow of the game is hindered by the troublesome input operation of the intention display, and the sense of speed, power and realism of the game is significantly impaired.

[0005]

SUMMARY OF THE INVENTION The present invention greatly reduces the complexity and difficulty of the input method of intention display seen in the conventional computer game apparatus as described above, and provides a sense of speed of the computer game. Aiming to greatly enhance the power and realism, the mechanical input means interposed to convey the player's intention to the computer is eliminated, and the intention display form of the body part in which the player's intention is embodied is directly sent to the computer As an input information source for the game. To do so, the task is to correctly interpret the intention expression form of the body part that is the input information source of the computer, identify the characteristics of the intention expression form, and identify the type of intention embodied in the intention expression form. Become.
Another object of the present invention is to maintain a fair and attractive progress of the game by imposing a burden on the player when the intention display form of the player is not properly expressed in accordance with a predetermined rule in the computer game. And

The present invention also provides a technique for correctly recognizing the intention expression form as a direct input information source for communicating the intention expression form of the body part to the computer, and a two intention expression form based on the technique. Technologies for comparative evaluation
For example, by applying to the field of gesture expression such as dance choreography, rhythm exercise or sign language technique exercise,
The aim is to enjoy the gestures and movements of those gestures as if they were a computer game, or to improve the skill of gesture expression.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 5 show a computer game process of competing with a computer for "rock-paper-scissors", and the present invention applied to a rock-paper-scissors-game computer game device (a game machine for playing rock-paper-scissors with a virtual opponent created by a computer). An example is shown in FIG.
Is a method of identifying and specifying the type of intention (kind of intention) embodied in the form of the body part (hands) expressed by rock-paper-scissors (form of intention), and a computer that competes for rock-paper-scissors.
5 is a flowchart showing an example of a match evaluation method in a game, FIG. 5 is an external perspective view of an example of a rock-paper-scissor / game computer / game apparatus according to the present invention, FIG. 4 is a block diagram of the computer / game apparatus, and FIG. FIG. 3 is a diagram showing an intention display form / type contrast diagram for explaining one method for identifying and specifying the type of intention described above. FIG. It is a comparison chart of intention type evaluation.

As shown in FIG. 5, the rock-paper-scissor / game computer / game apparatus has a display 52 provided on the front surface of a housing 51, and a plurality of camera devices (photographing means) 53 a provided on the upper front surface of the housing 51. , 53b are attached, and two illumination devices 54ap, 54aq and two illumination devices 54bp, 54bq are provided for each of the camera devices 53a, 53b. A computer is housed inside the housing 51, and a speaker 58 and a timing setting means 59 for selecting a detection timing of a finger form (intention display form) on a rock-paper-scissor rock are viewed from the front of the housing 51. The configuration of the timing setting means 59 is not limited to a hardware device, but can be configured only by software. A limited space located in front of the housing 51 (a space within a range where the camera devices 53a and 53b can accurately capture an object) is a predetermined play space 55.
In this predetermined play space 55, the player
With the stage 51a in the background, at the timing of the predetermined rock-paper-scissors "Pon", use the fingers to form the rock-paper-scissors' intention display form "Stone (goo)", "Scissors (choki)", "Paper (par)" Is displayed.

On the other hand, a display of a rock-paper-scissors intention display form (virtual opponent's intention display form) 57 to be displayed by a computer-generated rock-paper-scissors-game virtual opponent (player's rock-paper-scissors opponent) is displayed on the display 52. Competes with this virtual opponent for rock-paper-scissors / games. Needless to say, the intention display forms ("stone", "scissors", "paper") 56, 57 of the player and the virtual opponent are between the intention display forms ("stone", "scissors", "paper") according to the rules of rock-paper-scissors. (The type of intention is represented by “goo”, “choki”, and “par”) is embodied.

Each of the virtual partner's intention display modes 57 is randomly drawn out by, for example, a computer program. The virtual partner's intention display form 57 displayed on the display 52 is not necessarily a finger form (“stone”, “scissors”).
Instead of "paper"), it may be a character, a symbol, a graphic, or the like that indicates the type of intention of the virtual opponent, or it may be possible to display only the result of the game between the player and the virtual opponent. Further, it is conceivable that the virtual partner's intention display mode 57 is not displayed on the display 52, but is expressed by voice using the speaker 58, or the virtual partner's intention display mode is displayed by a separately provided doll. Note that the intention display form of the rock-paper-scissors rock is usually expressed by fingers, but it is also possible to express the form by disposition of both feet. In this case, on the stage 51a in the predetermined play space 55, "Goo"" Choki "
What is necessary is just to express the arrangement form of both feet corresponding to the type of intention of "par".

The player's intention display form 56 is illuminated by the lighting devices 54ap, 54aq, 54bp, 54bq, and photographed by the camera devices 53a, 53b. Camera device 5
The image of the intention display form 56 photographed in 3a and 53b is subjected to image processing (binarization of photographed image, image noise removal, image clipping, etc.) by a computer to form an identification image, and the computer performs this identification. From the image, the type of the player's intention embodied in the player's intention display form 56 (any type of “goo”, “choki”, and “par”) is specified, and further, the computer's intention type and virtual By comparing the opponent's intention type 57 with the opponent's intention type (e.g., the player's win or loss as a result of the rock-paper-scissors), the evaluation and judgment are made, and the judgment result is notified on the display 52 on the display 60 and displayed. At the same time or in place of the display 60, the result of the rock-paper-scissors game may be reported from the speaker 58 by voice.

In any case, what is important in the present invention is that the characteristics of the player's intention display form 56 are
a and 53b, and the image processing is rapidly performed to obtain a clear identification image analysis. For this purpose, as described in the above embodiment, several means are employed. That is, when the player's intention display form 56 is photographed from only one direction with one camera device, depending on the position and inclination of the intention display form 56 with respect to the camera device, the characteristics of the intention display form 56 may be photographed. In some cases, the characteristics of the intention display form 56 cannot be captured. Therefore, in the present invention, the intention display form 56
Using at least two camera devices 53a and 53b for photographing the image from different directions, in order to accurately photograph the characteristics of the intention display form 56, the blind spot is minimized. In order to eliminate the blind spot, if necessary, three or more camera devices are provided to display the intention display form 56.
May be taken from more appropriate directions. Further, when shadows appear in the intention display form 56 due to illumination, many shadows and strong shadows remain in the captured image of the intention display form 56, and when the image is binarized and analyzed in the process of image processing, these shadows are removed. In addition to being a hindrance to analysis and requiring a large amount of computation for image analysis and impairing rapid image processing, in the present invention, the light source of the illumination device is By arranging the optical balance aside, the shadows generated on the intention display form 56 due to the illumination from each light source are canceled each other, thereby obstructing the image analysis and greatly increasing the amount of calculation for the image analysis. To reduce it. In the above embodiment, a minimum of two lighting devices 54ap, 54aq and a lighting device 54b are provided beside each camera device 53a, 53b.
p, 54 bp. Originally, if the light source of the illumination is arranged on the optical axis of each of the camera devices 53a and 53b in theory, the problem of shading does not occur, but since the arrangement is physically impossible in reality, As a practical alternative, if the light source of the lighting device is formed in a ring shape (donut shape) and the ring-shaped light source is arranged concentrically with the optical axis of the camera device, one lighting device is provided for each camera device. Base,
Shading generated on the intention display form 56 can be suppressed. Further, the material, the color, and the color tone of the stage 51a which is the background of the intention display form 56 are examined so that the outline of the intention display form 56 can be clearly displayed.

In the conventional rock-paper-scissors-game computer / game device, the timing of the rock-paper-scissors “pong”, that is, the timing of detecting (image recognition) the captured image of the intention display form 56 is fixedly set on the computer side. ing. For this reason, the timing of the rock-paper-scissors of the player may not be properly adjusted depending on the player's sense of rhythm, and it is particularly difficult for the infant to adjust the timing. On the other hand, in the above-described embodiment of the present invention, the timing setting means 59 which can set the timing of "rock-paper-scissors" pong "" from the player side is provided. That is, the timing setting means 59 has condition checking means for analyzing the imaging results of the camera devices 53a and 53b to check whether or not a certain condition is satisfied. The timing of image identification is determined by using the moment when the condition is satisfied as a trigger. As a result, the setting of the timing is determined on the player side, and the difficulty of the player adjusting the timing is eliminated. Incidentally, the timing setting means 59 can be constituted by only software without using a hardware device.

Next, the process of the method of identifying the intention display form of the body part and the method of evaluating the competition of the computer game used in the above-mentioned rock-paper-scissors / game computer / game device are as shown in FIG. The processes of the identification method and the match evaluation method will be described with reference to FIGS. 2, 3, and 4. First, in step S1, the intention display form / type inquiry file F1 and the intention type evaluation file F
2 and a payout program F3 of the type of the intention of the virtual partner are set and stored in the recording device 42 of the computer 40.
The intention display form / type inquiry file F1 is a data group indicating the correspondence between various intention display forms (each identification image) and the type of intention embodied therein. FIG. 2 is a diagram showing the intention of the intention display type / type contrast diagrammatically illustrating the outline of F1.

The intention type evaluation file F2 includes various combinations of the player's intention type (intention type symbol) and the virtual opponent's intention type (intention type symbol), and in accordance with well-known rock-paper-scissors rules, these combinations. This is a data group that determines the relationship between the wins and losses of the players (that is, the superiority or inferiority between various types of intentions). FIG. 3 is a diagram illustrating the gist of the intention type evaluation file F2 for the purpose of explanation.

Then, as shown in the comparison chart of the intention type evaluation of Z3, the timing of the intention display form ("stone", "scissors", "paper") displayed by the player with the rocks is delayed or delayed (retarded). Both players are promised to lose if they are too early (early out). Also, when the player displays the intention display form outside the predetermined play space 55 or the expression of the intention display form 56 is incomplete and a clear identification image cannot be obtained from the intention display form 56, the player loses. As promised. Such a contract raises the tension of the game by giving the player a disadvantage in the progress of the game if the player's expression of intention is incomplete or violates the rules of rock-paper-scissors. However, in order to maintain a fair and attractive game, the means of evaluation that is disadvantageous to the player in the progress of the game is, as in the above-described embodiment, by disadvantageously evaluating the type of player's intention. In addition to determining that the player has lost the game, the game may be confiscated, for example, by confiscating the game. In addition, the program F3 for extracting the type of the intention of the virtual opponent is a computer for randomly extracting the type of the intention of the virtual opponent by the computer.

Next, in step S2, the timing setting means 59 selects whether the timing setting / instruction of "paper-scissors" pong "" is left to the computer as in the prior art or determined according to the conditions of the player. . Now that the rock-paper-scissors / game preparation is complete, in step S3, the player and the virtual opponent match each other to indicate any intention of “goo”, “choki”, and “par”. Then, in step S4,
The player's intention display form 56 is photographed by the camera device 53 (53a, 53b), and the photographed image (imaged) P1
Is obtained. Next, in step S5, it is checked whether or not the timing of the intention display of the previous player is correct, and if the timing is correct, in step S6, the form of intention display of the player ("stone") is performed.
It is checked whether or not the expression of “scissors” and “paper”) is normally expressed in the play space 55. If the result is good, in step S7, the computer 40
The central processing unit (arithmetic means) 41 processes the image P1 of the player's intention display form. In the image processing, the image pickup P1 is binarized to be converted to a binarized image P2 including noise, the binarized image P2 is subjected to noise removal processing to form an image P3, and further, the image P3 is clipped, and step S8 is performed. , An identification image P4 is obtained. And step S
In step 9, the central processing unit (arithmetic means) 41 identifies the type of the player's intention by comparing the image data representing the characteristic of the identification image P4 with the data of the intention display form / type inquiry file F1. A comparison is made as to whether the type of intention of the virtual partner is different from the type of intention of the virtual partner. As a result, if the two intention types are different from each other, the central processing unit 41 compares the combination of the two intention types with the data of the intention type evaluation file F2 by the central processing unit 41 in step S11 to evaluate the superiority or inferiority of the player's intention type. (Win / Loss Judgment) and Step S12
In, the result of the evaluation is notified by the video output device 44 and the display 52 or the audio output device 45 and the speaker 58, and one game of rock-paper-scissors ends.

If the type of the player's intention and the type of the virtual opponent's intention are the same in step S10, the process returns to step 2 where the rock-paper-scissors are performed again and the above process is repeated. On the other hand, if it is determined in step S5 that the timing of the player's intention display has not been reached, or if it is determined in step S6 that the player's intention display form has not been properly displayed, the imaging P1no image processing is not completed. Proceeding to step S11, the player loses the game in light of the data in the intention type evaluation file F2 and is notified.
