(Instruction input device)
The instruction input device 1 according to the embodiment of the present invention shown in FIG. 1 inputs an instruction for the operation of a character active in the game space to the game control unit 21 that controls the game space. The instruction input device 1 intuitively operates a character active in a virtual game space by using a sound symbol word that makes an image of the character's movement as a character's movement instruction. The instruction input device 1 calculates the evaluation value of the evaluation scale corresponding to the movement of the character from the impression of the sound symbol word input by the user, such as the sound element of the sound symbol word, and calculates the calculated evaluation value. It is converted into an operation instruction of the game device 2.

In the embodiment of the present invention, the evaluation scale is an adjective pair such as "static ⇔ dynamic", "elastic ⇔ inelastic", and the evaluation value is the method described in Patent Document 2. It is calculated.

In the embodiment of the present invention, the game will be described as an adventure game in which a character moves from left to right on the screen in a two-dimensional game space. The character acquires the items placed in the game space, and aims at the goal while avoiding and defeating the enemy. In the embodiment of the present invention, the instruction input device 1 converts the sound symbol word input by the user into each action of the character of "move right" or "jump" to operate the character in the game space. The adventure game described here is only an example, and is not limited to this. The action type of the character in the game space is determined by the specifications of the game. The instruction input device 1 can convert the sound symbol word input by the user into an operation permitted by the character in the game control unit 21.

The instruction input device 1 will be described with reference to FIG. The instruction input device 1 is connected to the game device 2. The game control unit 21 activates the character in the game space according to the operation instruction of the character input from the instruction input device 1.

The instruction input device 1 includes an acquisition unit 11, a calculation unit 12, a determination unit 13, and an instruction unit 14.

The acquisition unit 11 acquires voice data input by the user's voice. The acquisition unit 11 acquires the voice emitted by the user using a microphone or the like, and acquires the voice data. The voice data acquired here is a piece of data until the user's voice input is completed. In the embodiment of the present invention, the user emits a sound symbolism that makes the image of the movement of the character, and the acquisition unit 11 acquires the voice data of the sound symbolism.

The calculation unit 12 calculates the evaluation value in the evaluation scale corresponding to the movement of the character from the sound symbol words included in the voice data. An evaluation scale may be associated with each type of character movement. The calculation unit 12 calculates an evaluation value in an evaluation scale associated with any type of operation.

In the embodiment of the present invention, the movement of the character and the evaluation scale corresponding to the movement are associated in advance, and the evaluation value in the evaluation scale corresponding to the movement of the character is calculated from the sound symbol words included in the voice. .. Here, in order to calculate the evaluation value, phonological elements, flexions, etc. included in the sound symbolism may be used.

The evaluation scale corresponding to the movement of the character is associated with an evaluation scale that makes it easy to image the movement of the character and a condition for specifying the movement in the evaluation scale. For example, a plurality of sound symbolisms that make it easy to imagine the movement of the character are selected, and the evaluation value of each evaluation scale of the selected sound symbolism is calculated. By excluding from each evaluation scale an evaluation scale having the same evaluation value as other sound symbol words and an evaluation scale having a variation in the evaluation value of the selected sound symbol word, it is easy to imagine the operation of the evaluation scale. Can be identified.

In the embodiment of the present invention, a method of specifying an evaluation scale that makes it easy to image the movement of a character in a virtual space will be described. In advance, as an evaluation scale for movement, "heavy ⇔ light", "static ⇔ dynamic", "strong ⇔ weak", "uneven ⇔ flat", "elastic ⇔ inelastic", "Slip ⇔ sticky" and "sharp ⇔ dull" are selected.

In addition, "sutasuta (briskly, etc.)", "tekuteku", "dadada", and "sassatsu" are selected as sound symbolisms that make it easy to imagine the character's movement "moving to the right". For each sound symbolism selected, compare the evaluation values of the selected evaluation scale. As a result of excluding the exclusion of the evaluation scales having the same evaluation values as other sound symbols and the evaluation scales with variations in the evaluation values of the selected sound symbols from the evaluation scales related to movement, the movement "move right". "Static ⇔ dynamic" is specified as an evaluation scale for. The English word "briskly" attached to "Sutasuta" is an English translation of the image of the sound symbolism "Sutasuta". “Briskly” is an example of an English sound symbol that makes it easy to imagine the character's movement “moving to the right”, and is not limited to this.

"Pyon (jump, etc.)" and "fluffy (lightly, softly, fluffy, etc.)" are selected as sound symbolisms that make it easy to imagine the character's movement "jump." For each sound symbolism selected, compare the evaluation values of the selected evaluation scale. As a result of excluding the exclusion of the evaluation scales having the same evaluation values as other sound symbols and the evaluation scales with variations in the evaluation values of the selected sound symbols from the evaluation scales related to movement, regarding the movement "jump". As an evaluation scale, "elastic ⇔ inelastic" is specified. The English words "jump", etc. attached to "pyon", "fluffy", etc. are English translations of the images of each sound symbolism. “Jump” and the like are examples of English sound symbolisms that make it easy to imagine the character's movement “jump”, and are not limited to this.

In the embodiment of the present invention, as shown in FIG. 2, the adjective pair of the evaluation scale "static ⇔ dynamic" is associated with the character movement type "right movement", and the character movement type "jump". Is associated with the adjective pair of the evaluation scale "elastic ⇔ inelastic". Therefore, the calculation unit 12 calculates the evaluation value for the adjective pair of the evaluation scale "static ⇔ dynamic" and the adjective pair of "elastic ⇔ inelastic" from the sound symbol words included in the voice data. ..

Here, detailed processing of the calculation unit 12 will be described.

First, the calculation unit 12 specifies a sound symbol word included in the voice data acquired by the acquisition unit 11. As a method of specifying a sound symbol word, there are a method of converting voice data into character text, a method of using a model learned the correlation between voice data and a sound symbol word, and the like. When the sound symbolism of the voice data emitted by the user is specified, the calculation unit 12 converts the impression of the phonological element of the sound symbolism into the evaluation value in the evaluation scale. The calculation unit 12 may convert the voice data into the evaluation value in the evaluation scale by using the model which learned the correlation between the voice data and the evaluation value in the evaluation scale of the sound symbol word included in the voice data. .. Further, the calculation unit 12 may acquire the evaluation value in the evaluation scale converted from the sound symbol word included in the voice data from the module that converts the sound symbol word into the evaluation value in the evaluation scale.

In the embodiment of the present invention, the evaluation scale and the evaluation value are the adjective pair and the image evaluation value disclosed in Patent Document 2. The evaluation value is calculated by the method shown in Patent Document 2. Specifically, the calculation unit 12 has a phonological morphology database that stores phonological morphological analysis information for analyzing the phonological morphology of phonological symbolic words by phonological elements and flexions, and gives an impression of the phonological symbolic word for each phonological morphology. It is possible to refer to the quantitative image table in which the evaluation values quantified for each evaluation scale expressing the influence by the preset morphological expression are stored. As vowel morphology analysis information, "vowel; V", "consonant; C", "sokuon" tsu "; Q", "sokuon; N", "long vowel; R", "(at the end of the word)" ri "; ri", "Dakuon / semi-voiced sound", "repetition", etc. are memorized. Furthermore, the phoneme morphology analysis information is "/ a /, / i /, / u /, / e /, / o /" as the phoneme notation information of "vowel", and "/ k /," as the phoneme notation information of "consonant". / g /, / s /, / z /, / t /, / d /, / n /, / h /, / b /, / p /, / m /, / r /, / w / "," As phoneme notation information for "consonants with sokuon", "/ ky /, / gy /, / sy /, / zy /, / ty /, / dy /, / ny /, / hy /, / by /, / py /, "/ My /, / ry /", "/ Q /" as the phoneme notation information of "sokuon" tsu "", "/ N /" as the phoneme notation information of "sound repellent", "/" as the phoneme notation information of "long sound" Store "/ ri /" as phoneme notation information for "R /" and "(at the end of the word)" ri "", respectively. The quantitative image table is an image evaluation obtained by quantifying the scale of the influence on the image of the sound symbolism with or without each phonological form for each phonological form obtained by the evaluation experiment for each adjective pair having a contrasting meaning. Store the value. The calculation unit 12 analyzes the phoneme morphology of the sound symbolism included in the voice data input by the user based on the phoneme morphology analysis information of the phoneme morphology database. Based on the analysis result, the calculation unit 12 specifies the evaluation value for each evaluation scale for each phoneme form of the sound symbolism from the quantitative image table, and based on the evaluation value for each specified phoneme form and each evaluation scale. , Quantify the impression of sound symbolism.

The calculation unit 12 is not limited to the above method, and may be able to quantify the input image of the sound symbol word and calculate it as an evaluation value. Further, for sound symbol words in languages different from Japanese such as English and Chinese, the calculation unit 12 only needs to be able to calculate the evaluation value in the evaluation scale corresponding to the movement of the character by a method suitable for the language. The calculation method does not matter. For example, a phonological morphology database and a quantitative image table may be provided for each language, and an evaluation scale corresponding to the movement of the character in each language may be specified. In that case, the calculation unit 12 may calculate the evaluation value in the evaluation scale corresponding to the movement of the character in the language by referring to the phoneme form database and the quantitative image table corresponding to the language of the input sound symbolism. good.

The determination unit 13 compares the evaluation value with the threshold value and determines whether or not to cause the character to perform an action. The determination unit 13 compares the evaluation value for each evaluation scale with the threshold value, and determines whether or not the character is to be operated, and the operation type of the character when the character is to be operated. The determination unit 13 determines whether or not to operate the character based on the result of comparing the evaluation value calculated by the calculation unit 12 and the threshold value for the adjective pair corresponding to the movement of the character, and the operation type when the operation is performed. decide.

When it is determined that the character is to be operated, the instruction unit 14 outputs an instruction to cause the character to perform an operation and an operation type thereof.

The conditions for the determination unit 13 to determine the operation type from the evaluation value in the evaluation scale are predetermined according to the specifications of the evaluation scale and the like.

In the embodiment of the present invention, the evaluation value of the evaluation scale takes a positive value when the sound symbolism to be evaluated is close to the adjective described on the right side of the adjective pair, and is close to the adjective described on the left side of the adjective pair. In this case, since it takes a negative value, the threshold value becomes, for example, zero.

For example, if the evaluation value of the input sound symbolism evaluation scale "static ⇔ dynamic" is positive, it means that a sound symbolism with a strong "dynamic" impression has been input. If the evaluation scale "static ⇔ dynamic" satisfies the condition that a positive value is taken, the operation type "move right" is determined. If the evaluation value is negative for the evaluation scale "elastic ⇔ non-elastic", it means that a sound symbol word with a strong impression of "elasticity" has been input. If the input sound symbol word evaluation scale "elastic ⇔ non-elastic" satisfies the condition of taking a negative value, the action type "jump" is determined.

The determination unit 13 determines whether or not to operate the character and the operation type when the character is operated, based on the input evaluation value of the sound symbol word and the condition for determining the operation type.

When the evaluation value takes a positive value for the input evaluation scale "static ⇔ dynamic" of the sound symbol word, the determination unit 13 determines the action type "right movement" of the character. When the evaluation value takes a negative value, the determination unit 13 determines that the character is not operated or the operation type "move to the right" is not performed.

When the evaluation value of the input sound symbol word evaluation scale "elastic ⇔ non-elastic" takes a negative value, the determination unit 13 determines the action type "jump" of the character. When the evaluation value takes a positive value, the determination unit 13 determines that the character is not operated or the operation type "jump" is not performed.

The instruction unit 14 gives an instruction regarding the movement of the character to the game control unit 21 based on the determination by the determination unit 13. When the determination unit 13 determines "move right" or "jump" as the action of the character, the instruction unit 14 inputs an instruction to cause the character to perform the action of "move right" or "jump". When the determination unit 13 decides not to "move to the right" or "jump" as the movement of the character, the instruction unit 14 may input an instruction regarding the movement of the character to the game control unit 21. And you don't have to enter it. For example, when the character is moving to the right in the game space, if the instruction unit 14 inputs to the game control unit 21 that the instruction unit 14 does not "move to the right", the game control unit 21 stops the right movement in the game space. , You may control the character.

Also, depending on the specifications of the game, it may be possible to allow simultaneous execution of multiple actions, such as jumping while moving to the right. The determination unit 13 has an evaluation value of the evaluation scale "static ⇔ dynamic" associated with the character's motion type "right movement" and an evaluation scale "elastic" associated with the character's motion type "jump". The movement of the character may be determined by referring to both of the evaluation values of "⇔ inelastic". For example, when the input sound symbol word takes a positive value for the evaluation scale "static ⇔ dynamic" and a negative value for the evaluation scale "elastic ⇔ inelastic", the determination unit 13 Determines that the determination unit 13 causes the character to simultaneously execute the operation types "move right" and "jump". The instruction unit 14 inputs to the game control unit 21 an instruction to simultaneously execute the right movement and the jump of the character according to the determination by the determination unit 13.

In this way, by calculating the evaluation value of the evaluation scale corresponding to the movement of the character from the sound symbolism input by the user and operating the character according to the result, the user can intuitively think of the character as the character. Can be operated.

Here, the determination unit 13 has described the case where one evaluation scale is associated with one movement of the character, but the present invention is not limited to this. A plurality of evaluation scales may be associated with one movement of a character, and the movement may be determined according to the evaluation values of these evaluation scales.

The determination unit 13 may also determine parameters in the operation of the character. The parameters determined by the determination unit 13 are input from the instruction unit 14 to the game control unit 21, and are referred to when determining the operation content or operation details of the character. Here, the parameters are the amount of movement, the speed, the animation of the character during operation, and the like. The parameter may be a fixed value.

Alternatively, the parameter may be determined according to the degree of deviation between the evaluation value and the threshold value. As shown in FIG. 3, an evaluation scale for determining a character's motion type and parameters is predetermined. For example, when the movement amount of the operation type "right movement" is changed according to the degree of deviation between the evaluation value and the threshold value, the determination unit 13 moves the evaluation value larger as the evaluation value takes a larger value of plus, and moves it larger by the plus zero. Determine the parameter value so that the closer the value is, the smaller the movement is. When changing the movement amount of the operation type "jump", the determination unit 13 makes the jump higher as the evaluation value becomes larger than minus, and jumps lower as the evaluation value becomes closer to zero. , Determine the parameter value.

Thereby, the operation content of the character can be determined according to the image of the input sound symbol word.

Further, in FIG. 3, the case where the evaluation scale for determining the movement type of the character and the evaluation scale for determining the parameter are the same has been described, but the present invention is not limited to this. As shown in FIG. 4, an evaluation scale for determining the movement type of the character and an evaluation scale for determining the parameters may be set individually. The calculation unit 12 calculates evaluation values for both the evaluation scale that determines the movement type of the character and the evaluation scale that determines the parameters. The determination unit 13 refers to the evaluation value of the evaluation scale that determines the movement type of the character, determines whether or not to operate the character, and after determining the movement, refers to the evaluation value of the evaluation scale that determines the parameter. To determine the operating parameters of the character. The determination unit 13 determines the parameters in the movement, for example, according to the degree of deviation between the evaluation value and the threshold value in the evaluation scale corresponding to the parameters of the movement of the character. At this time, the relationship between the value taken by the evaluation value and the parameter is predetermined, for example, the larger the evaluation value is, the larger the movement amount is, and the smaller the negative value is, the smaller the movement amount is.

This makes it possible to determine the action type and action content of the character according to the complex image of the input sound symbolism.

The case where the parameter at the time of operation is determined from the evaluation value of the evaluation scale has been described, but the present invention is not limited to this. For example, the determination unit 13 may determine a parameter in operation from the feature amount in the voice data. The feature amount in the voice data is the loudness of the voice, the frequency of the voice, and the like.

As a result, it is possible to determine the action content of the character in consideration of not only the image of the input sound symbol word but also other features.

In step S52, the instruction input device 1 compares the evaluation value of the evaluation scale “elastic ⇔ non-elastic” of the operation type “jump” with the threshold value, and determines whether or not to jump. If the evaluation value is a negative value, the instruction input device 1 determines "jump" in step S53. If the evaluation value is a positive value, the instruction input device 1 decides not to "jump" in step S54.

In step S55, the instruction input device 1 compares the evaluation value of the evaluation scale “elastic ⇔ non-elastic” of the operation type “jump” with the threshold value, and determines whether or not to jump.
