Description

  The present invention relates to an operation reception device, an operation determination method, and a program that can more easily perform operations such as determination of selection items.

Conventionally, game controllers have been widely used as input devices for home game devices. This game controller is generally provided with direction keys (cross keys) and various buttons. Then, the player can perform a desired operation input by appropriately pressing these keys and buttons.
In recent years, game controllers in which analog sticks are further arranged are also known. In this analog stick, for example, a stick urged in an upright state (to the base point) is supported in a tiltable manner. The player can input an arbitrary direction in a predetermined plane by freely tilting and moving the stick in the standing state with a finger or the like. In addition, it is possible to perform input by adjusting the amount of force according to the angle (movement amount, etc.) of the stick.

  As a conventional technique of a game apparatus using such an analog stick, a technique capable of easily selecting information desired by a player is also disclosed (for example, see Patent Document 1).

JP 2009-34375 A (pages 12-34, FIG. 1)

  In the game device of Patent Document 1 described above, information such as characters can be selected according to the tilt direction of the stick and the rotation amount of the stick in the tilted state. That is, the player can select desired information by tilting the stick and rotating the stick as it is.

However, as represented by the technique disclosed in Patent Document 1, conventionally, in order to finally determine (determine) the selected information, another operation other than the stick is further required. In other words, the player cannot determine the input of the selected character or the like unless two operations such as pressing the ○ button or the like are separately performed while the character or the like is selected with the stick.
Many players felt that these two operations were complicated. For this reason, there has been a demand for performing easier operations from selection of characters and the like to determination.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide an operation reception device, an operation determination method, and a program capable of performing an operation such as determination of a selection item more easily. And

  An operation reception device according to a first aspect of the present invention is an operation reception device in which an operation element (for example, a real or virtual stick) that automatically returns to a base point is movably held, and includes a detection unit, a screen A generation unit, a selection unit, and a determination unit are included.

  First, the detection unit sequentially detects the position of the operation element based on, for example, a supplied voltage value. The screen generation unit generates a selection screen including an image to be selected (for example, an image showing a selection item). The selection unit selects an image in the selection screen based on the detected position of the operation element. For example, the selection unit selects an image that matches the position of the operation element or the position of the cursor corresponding to the operation element. Then, after the image is selected, the determination unit determines whether the selected image is determined or canceled based on the movement state when the operator returns to the base point. For example, when it is specified that the operator has manually returned to the base point (by the player's operation) according to the movement state, the determination unit determines the determination of the selected image. On the other hand, when it is specified that the operator has automatically returned to the base point (without the player's operation) depending on the movement state, the release of the selected image is determined. Note that such assignment of determination and cancellation is an example, and can be switched as appropriate.

That is, after the player moves the operation element with a finger or the like and selects a desired selection item (desired image), the selection item is determined or released according to how the operation element is handled (switched). You can enter. For example, when the operator is manually returned to the base point (that is, when the operator is returned with a finger or the like), the selection item selection is input, and conversely, the operator is automatically touched without touching it. For example, when returning to the base point (that is, when a finger or the like is released from the operation element), the cancellation of the selection item is input.
That is, the player can instruct from selection of an item to determination and release of the selected item by operating only the operator without operating other buttons.
As a result, operations such as determination of selection items can be performed more easily.

  An operation accepting apparatus according to a second aspect of the present invention is an operation accepting apparatus in which an operator (e.g., an actual stick) urged to a base point is supported so as to be movable in the entire circumferential direction. A screen generation unit, a cursor synthesis unit, a selection unit, and a determination unit.

  First, the detection unit sequentially detects the position of the operation element based on, for example, the voltage value of the supplied biaxial signal. In addition, the screen generation unit generates a selection screen in which a plurality of images (for example, each image showing each selection item) is arranged radially. The cursor synthesis unit synthesizes the cursor at a corresponding position on the generated selection screen based on the detected position of the operation element. The selection unit selects an image in the selection screen based on the position of the synthesized cursor. For example, an image matching the position where the cursor is synthesized is selected. Then, after the image is selected, the determination unit determines whether the selected image is determined or canceled based on the movement trajectory when the operator returns to the base point. For example, when it is specified by the movement locus that the operator has been manually returned to the base point (by the player's operation), the determination unit determines the determination of the selected image. On the other hand, when it is specified that the urged operation element has automatically returned (without operation by the player), the release of the selected image is determined. Note that such assignment of determination and cancellation is an example, and can be switched as appropriate.

That is, after the player moves the operation element with a finger or the like and selects a desired selection item (desired image), the selection item can be determined or released depending on how the operation item is handled. For example, when the operator is manually returned to the base point (that is, when the operator is returned with a finger or the like), the selection of the selection item is input, and conversely, the operator is automatically activated by the biasing force. For example, when returning to the base point (that is, when a finger or the like is released from the operation element), the cancellation of the selection item is input.
That is, the player can instruct from selection of an item to determination and release of the selected item by operating only the operator without operating other buttons.
As a result, operations such as determination of selection items can be performed more easily.

  The operation accepting apparatus according to the third aspect of the present invention is controlled such that a virtual operator (such as a virtual stick) displayed on the touch panel moves in a region centered on the base point according to the operation, In addition, the operation receiving device is controlled to automatically return to the base point when there is no operation, and includes a detection unit, a screen generation unit, a selection unit, and a determination unit.

  First, the detection unit sequentially detects the position of the operation element corresponding to the operation or the like based on, for example, the voltage value of the signal supplied from the touch panel. In addition, the screen generation unit generates a selection screen in which a plurality of images (for example, each image showing each selection item) are arranged radially around the base point on the touch panel. The selection unit selects an image in the selection screen based on the detected position of the operation element. For example, an image that matches the position of the operator that has been operated and moved is selected. Then, after the image is selected, the determination unit determines whether the selected image is determined or canceled based on a factor when the operator returns to the base point. For example, when the factor is specified to be manual (by the player's operation), the determination unit determines the determination of the selected image. On the other hand, when the factor is specified to be automatic (not depending on the player's operation), the release of the selected image is determined. Note that such assignment of determination and cancellation is an example, and can be switched as appropriate.

That is, after the player moves an operation element displayed on the touch panel with a finger or the like and selects a desired selection item (desired image), determination or cancellation of the selection item is determined depending on how the operation element is handled. Can be entered. For example, when the operator is manually returned to the base point (that is, when the operator is returned with a finger or the like), the selection item selection is input, and conversely, the operator is automatically touched without touching it. For example, when returning to the base point (that is, when a finger or the like is released from the operation element), the cancellation of the selection item is input.
That is, the player can give instructions separately from selection of an item to determination and release of the selected item by operating only the operator without operating other buttons.
As a result, operations such as determination of selection items can be performed more easily.

The determination unit determines the determination of the selected image when the operator is manually returned to the base point, and specifies that the operator has automatically returned to the base point. In this case, the cancellation of the selected image may be determined.
In this case, after selecting the desired selection item (desired image), the operator is manually returned to the base point, and when the operator is automatically returned to the base point without touching the operator. The determination or release of the image can be input separately.

The detection unit sequentially detects the movement in the circumferential direction around the base point from the position of the operation element from which any image is selected,
The selection unit may select another image based on the movement of the operation element in the circumferential direction.
In this case, for example, the player selects one of the selection items (images) by tilting the operation element, and then rotates the operation element so as to draw an arc while tilting the operation element. (Image) can be easily selected again.

  An operation determination method according to a fourth aspect of the present invention includes a detection unit, a screen generation unit, a selection unit, and a determination unit, and an operator that automatically returns to a base point (for example, a real or virtual stick) Is an operation determination method in the operation reception device held movably, and includes a detection step, a screen generation step, a selection step, and a determination step.

  First, in the detection step, for example, the position of the operation element is sequentially detected based on the supplied voltage value or the like. In the screen generation step, a selection screen including an image to be selected (for example, an image showing a selection item) is generated. In the selection step, an image in the selection screen is selected based on the detected position of the operation element. For example, in the selection step, an image that matches the position of the operation element or the position of the cursor corresponding to the operation element is selected. Then, in the determining step, after the image is selected, determination or cancellation of the selected image is determined based on the movement state when the operator returns to the base point. For example, when it is specified that the operator has manually returned to the base point (by the player's operation) according to the movement state, the determination unit determines the determination of the selected image. On the other hand, when it is specified that the operator has automatically returned to the base point (without the player's operation) depending on the movement state, the release of the selected image is determined. Note that such assignment of determination and cancellation is an example, and can be switched as appropriate.

That is, after the player moves the operation element with a finger or the like and selects a desired selection item (desired image), the selection item is determined or released according to how the operation element is handled (switched). You can enter. For example, when the operator is manually returned to the base point (that is, when the operator is returned with a finger or the like), the selection item selection is input, and conversely, the operator is automatically touched without touching it. For example, when returning to the base point (that is, when a finger or the like is released from the operation element), the cancellation of the selection item is input.
That is, the player can instruct from selection of an item to determination and release of the selected item by operating only the operator without operating other buttons.
As a result, operations such as determination of selection items can be performed more easily.

  A program according to a fifth aspect of the present invention is configured to cause a computer (including an electronic device) to function as the operation accepting device.

  This program can be recorded on a computer-readable information recording medium such as a compact disk, flexible disk, hard disk, magneto-optical disk, digital video disk, magnetic tape, and semiconductor memory.

  The above program can be distributed and sold via a computer communication network independently of the computer on which the program is executed. The information recording medium can be distributed and sold independently of the computer.

  According to the present invention, operations such as determination of selection items can be performed more easily.

In the following, for ease of understanding, an embodiment in which the present invention is applied to a game device will be described. However, the present invention can be similarly applied to information processing devices such as various computers, PDAs, and mobile phones. it can. That is, the embodiment described below is for explanation, and does not limit the scope of the present invention. Therefore, those skilled in the art can employ embodiments in which each or all of these elements are replaced with equivalent ones, and these embodiments are also included in the scope of the present invention.

(Embodiment 1)
FIG. 1 is a block diagram showing a schematic configuration of a typical game device in which the operation accepting device according to the first embodiment of the present invention is realized. Hereinafter, a description will be given with reference to FIG.

  The game apparatus 100 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, an interface 104, a controller 105, an external memory 106, and a DVD (Digital Versatile Disc). ) -ROM drive 107, image processing unit 108, audio processing unit 109, and NIC (Network Interface Card) 110.

  Note that a DVD-ROM storing a game program and data is loaded into the DVD-ROM drive 107 and the game apparatus 100 is turned on, whereby the program is executed. Realized.

  The CPU 101 controls the overall operation of the game apparatus 100 and is connected to each component to exchange control signals and data.

  The ROM 102 records an IPL (Initial Program Loader) that is executed immediately after the power is turned on, and when this is executed, the program recorded on the DVD-ROM is read out to the RAM 103 and execution by the CPU 101 is started. The The ROM 102 stores an operating system program and various data necessary for operation control of the entire game apparatus 100.

  The RAM 103 is for temporarily storing data and programs, and holds programs and data read from the DVD-ROM and other data necessary for game progress and chat communication.

The controller 105 connected via the interface 104 receives an operation input performed when the user executes the game. For example, the controller 105 accepts an operation input such as selection (determination) of a predetermined selection item according to the operation input.
Details of the controller 105 will be described below with reference to FIG.

  FIG. 2A is a schematic diagram showing the appearance of the controller 105. As illustrated, the controller 105 is provided with a direction key 201, an operation button 202, a stick 203, and the like.

The direction key 201 (201R, 201L, 201U, 201D) is a key that is pressed, for example, when performing an operation input instructing each of the up, down, left, and right directions.
The operation button 202 (202M, 202B, 202T, 202S) is a button that is pressed when performing an operation input instructing determination or cancellation, for example.

The stick 203 (203R, 203L) is an operator that is operated when, for example, an instruction in each direction that is not limited to the upper, lower, left, and right directions on the operation surface is performed in an analog amount with a size.
Specifically, the stick 203 is urged in a standing state (to the base point) and supported so as to be tiltable. That is, as shown in FIG. 2B, the stick 203 is defined with an axis C perpendicular to the operation surface as a base point, and is urged by an elastic body such as a spring along the base point (axis C). Has been. For this reason, the stick 203 is held so as to be stationary at the base point in an initial state (a state in which the player is not operated). Further, the stick 203 can be tilted in any direction of the entire circumferential direction on the operation surface when operated (when operated by the player). That is, the stick 203 tilts from the axis C to the axis Tn, the axis Tm, etc., as shown in FIG. In this state, when the player releases his / her finger from the stick 203, the player automatically returns to the base point (axis C) by the urging force. That is, when the operation of the stick 203 is stopped (when a finger or the like is released), the stick 203 is held so as to automatically return to the base point.
Such a stick 203 outputs an analog signal having a variable voltage value, for example, by a variable resistor whose value changes according to a tilt angle with respect to a biaxial direction (X direction and Y direction) orthogonal to the axis C. By such a voltage value in the X direction and a voltage value in the Y direction, the tilt direction and tilt angle of the stick 203, that is, the position of the stick 203 on the XY plane can be obtained.
Note that the method of obtaining the position of the stick 203 is not limited to using such a variable resistor, and can be changed as appropriate. For example, the position (inclination direction and angle) of the stick 203 may be obtained using a strain gauge or the like.

  Returning to FIG. 1, data indicating the progress of the game, chat communication log (record) data, and the like are rewritably stored in the external memory 106 detachably connected via the interface 104. The user can record these data in the external memory 106 as appropriate by inputting an instruction via the controller 105.

  A DVD-ROM mounted on the DVD-ROM drive 107 stores a program for realizing the game and image data and sound data associated with the game. Under the control of the CPU 101, the DVD-ROM drive 107 performs a reading process on the DVD-ROM loaded therein, reads out necessary programs and data, and these are temporarily stored in the RAM 103 or the like.

  The image processing unit 108 processes the data read from the DVD-ROM by the CPU 101 or an image arithmetic processor (not shown) included in the image processing unit 108, and then processes the processed data on a frame memory ( (Not shown). The image information recorded in the frame memory is converted into a video signal (video signal) at a predetermined synchronization timing and output to a monitor connected to the image processing unit 108. Thereby, various image displays are possible.

The image calculation processor can execute a two-dimensional image overlay calculation, a transmission calculation such as α blending, and various saturation calculations at high speed.
In addition, the polygon information arranged in the virtual three-dimensional space and added with various kinds of texture information is rendered by the Z buffer method, and a rendered image is obtained by overlooking the polygon arranged in the virtual three-dimensional space from a predetermined viewpoint position. High speed execution of the obtained operation is also possible.

  Further, the CPU 101 and the image arithmetic processor operate in a coordinated manner, so that a character string can be drawn as a two-dimensional image in a frame memory or drawn on the surface of each polygon according to font information that defines the character shape. is there. The font information is recorded in the ROM 102, but it is also possible to use dedicated font information recorded in the DVD-ROM.

  The audio processing unit 109 converts audio data read from the DVD-ROM into an analog audio signal and supplies the analog audio signal to an external speaker to output the audio. For example, the sound processing unit 109 generates sound effects and music data to be generated during the game under the control of the CPU 101, and outputs sound corresponding to the sound effects from the speaker.

  The NIC 110 is for connecting the game apparatus 100 to a computer communication network (not shown) such as the Internet, and conforms to the 10BASE-T / 100BASE-T standard used when configuring a LAN (Local Area Network). Analog modems for connecting to the Internet using telephone lines, ISDN (Integrated Services Digital Network) modems, ADSL (Asymmetric Digital Subscriber Line) modems, cable modems for connecting to the Internet using cable television lines And an interface (not shown) that mediates between these and the CPU 101.

In addition, the game apparatus 100 uses a large-capacity external storage device such as a hard disk so that the ROM 102, the RAM 103, the external memory 106, the DVD-ROM attached to the DVD-ROM drive 107, and the like function. It may be configured.
Further, it is possible to adopt a form in which a keyboard for accepting a character string editing input from a user, a mouse for accepting various position designations and selection inputs, and the like are connected.

  Further, instead of the game apparatus 100 of this embodiment, a general computer (general-purpose personal computer or the like) can be used as the selection apparatus. For example, a general computer includes a CPU, a RAM, a ROM, a DVD-ROM drive, and a NIC, and an image processing unit that has a simpler function than that of the game apparatus 100, as with the game apparatus 100. In addition to having a hard disk as a storage device, flexible disks, magneto-optical disks, magnetic tapes, and the like can be used. In addition, a keyboard, a mouse or the like is used as an input device instead of a controller. Then, after the game program is installed, when the program is executed, it functions as an operation accepting device.

(Outline of operation reception device)
FIG. 3 is a block diagram showing a schematic configuration of the operation receiving device 300 realized by the game device 100 described above. The operation accepting device 300 is a device that allows a player (user) to operate the stick 203 (203R, 203L) of the controller 105 described above to determine a desired selection item. Hereinafter, a description will be given with reference to FIG.

  The operation reception device 300 includes a detection unit 310, a screen generation unit 320, a cursor composition unit 330, a selection unit 340, and a determination unit 350.

First, the detection unit 310 sequentially detects the position of the stick 203 based on, for example, voltage values of supplied analog signals in two axes (X direction and Y direction). That is, the detection unit 310 detects a position corresponding to the inverted state or the tilted state of the stick 203 based on the voltage value in the X direction and the voltage value in the Y direction.
Specifically, as shown in FIG. 4 (a), the detection unit 310 determines that the stick 203 is in an upright state along the axis C (base point) or in a tilted state such as the axes Tn, Tm. The position of the stick 203 on the XY plane is detected based on the voltage value in the X direction and the voltage value in the Y direction according to the state.
For example, when the stick 203 is standing, the detection unit 310 detects the position C (center C) that is the center of the circle E on the XY plane, as shown in FIG. This position C corresponds to the axis C and is similarly defined as a base point.
Further, when the stick 203 is in a tilted state, the detection unit 310 detects, for example, as a position Tn or a position Tm, as shown in FIG. 4C, according to the tilt direction and tilt angle. These positions Tn and Tm correspond to the axes Tn and Tm, and are represented as positions moved from the position C (base point) as indicated by arrows Yn and Ym.

Note that the detection unit 310 can detect the movement trajectory of the stick 203 because it measures a biaxial voltage value for each predetermined sampling period and holds a predetermined number of samplings (for the past).
For example, when the player tilts the stick 203 from the standing state (axis C) to the axis Tm, the detection unit 310 detects a movement locus from the position C to the position Tm as shown in FIG. To do. That is, in this case, since the player is operating the stick 203, the position C to the position Tm is not linear, and moves while moving to some extent.
When the player releases his / her finger from the stick 203 after tilting the stick 203 to the axis Tm, the detection unit 310 moves the locus from the position Tm to the position C as shown in FIG. Is detected. That is, in this case, since it returns to the base point by the urging force, it moves linearly from position Tm to position C.
Further, the detection unit 310 also detects other movement trajectories in accordance with the operation of the stick 203. For example, a movement locus is detected when the player rotates the stick 203 while tilting. That is, as shown in FIG. 5 (c), it moves from the displacement Tm to the position Tj in the circumferential direction centering on the position C (as if drawing an arc). From such a movement locus, it is possible to detect that the stick 203 has been rotated (revolved) in a tilted state from the position Tm to the position Tj.
The above-described CPU 101 or the like can function as such a detection unit 310.

Returning to FIG. 3, the screen generation unit 320 generates a selection screen in which predetermined selection items are arranged so as to be selectable. For example, a selection screen in which a plurality of images (for example, each image showing each selection item) is arranged in a scene where the player selects an item is generated.
Specifically, the screen generation unit 320 generates a selection screen in which the images SG are arranged radially from the center C as shown in FIG.
Note that the above-described image processing unit 108 can function as such a screen generation unit 320.

Returning to FIG. 3, the cursor compositing unit 330 synthesizes a cursor on the screen based on the standing state or tilted state (position) of the stick 203. That is, based on the position of the stick 203 detected by the detection unit 310 described above, the cursor is synthesized at a corresponding position on the selection screen generated by the screen generation unit 320 described above.
Specifically, as shown in FIG. 7A, when the position of the stick 203 (any position) is detected by the detection unit 310, the cursor synthesis unit 330 Synthesize the cursor at the corresponding position on the selection screen. That is, when the stick 203 is detected at the position C (standing position) in FIG. 7A, the cursor composition unit 330 composes the cursor C1 at the corresponding display position as shown in FIG. 7B. . When the stick 203 is detected at the position Tn or the position Tm (tilted state) in FIG. 7A, the cursor composition unit 330 moves the cursor C2 to the corresponding display position as shown in FIG. 7B. Alternatively, the cursor C3 is synthesized.
Note that the above-described image processing unit 108 can function as such a cursor composition unit 330.

Returning to FIG. 3, the selection unit 340 selects a selection item that matches the position of the cursor. That is, the image indicated by the display position of the cursor synthesized by the cursor synthesis unit 330 described above is selected.
Specifically, referring to FIG. 7B described above as an example, the selection unit 340 selects the image SG4 (defense) when the cursor C2 is synthesized, and when the cursor C3 is synthesized. , Select image SG2 (fight).
The selection unit 340 reselects the destination image when the cursor moves to another image after any image is selected. Specifically, it is assumed that the stick 203 moves in a circular arc from the position Tm to the position Tj as shown in FIG. 7C by rotating the stick 203 while tilting. In this case, as shown in FIG. 7 (d), the cursor to be combined also moves from the cursor C3 to the cursor C4 so as to draw an arc, so that the selection unit 340 displays the image SG3 indicated by the destination cursor C4. Select (Item) again.
Note that the above-described CPU 101 or the like can function as such a selection unit 340.

Returning to FIG. 3, after the selection item is selected, the determination unit 350 determines the determination or release of the selection item based on the movement trajectory (movement state) when the stick 203 returns to the base point. That is, when it is specified that the stick 203 has been returned to the standing state manually (by the player's operation) according to the movement locus detected by the detection unit 310 described above, the determination unit 350 selects the selected image (selection). Item) is determined. On the other hand, when it is determined that the stick 203 has automatically returned to the standing state (by the urging force), the determination unit 350 determines release of the selected image.
Specifically, as shown in FIG. 8A, the movement trajectory when the stick 203 returns from the position Tm (tilting state) to the position C (standing position) by the operation of the player exceeds the predetermined range. Will move while going. That is, the movement trajectory does not become linear, and some blurring occurs. Since it is specified from such a movement locus that the stick 203 has manually returned to the base point, the determination unit 350 determines the determination of the selected image.
On the other hand, as shown in FIG. 8B, the movement trajectory when the stick 203 is returned from the position Tm to the position C by the urging force moves linearly without exceeding the predetermined range. That is, the movement trajectory is not blurred and is linear. Since it is specified from such a movement locus that the stick 203 has automatically returned to the base point (by the biasing force), the determination unit 350 determines the cancellation of the selected image.
Note that the above-described CPU 101 or the like can function as such a determination unit 350.

(Outline of operation of the operation reception device)
Hereinafter, the operation of the operation receiving apparatus 300 having such a configuration will be described with reference to the drawings. As an example, the operation of the operation accepting apparatus 300 in the case where the player performs a process from selection to determination of a desired item by operating only the stick 203 will be described with reference to FIG. FIG. 9 is a flowchart showing a flow of operation determination processing executed by the operation reception device 300.

First, the operation reception apparatus 300 displays a selection screen (step S401).
That is, the screen generation unit 320 displays a selection screen as shown in FIG. 6 described above, for example.

  The operation reception device 300 clears the selection flag (step S402). That is, the selection flag indicating whether any image (selection item) on the selection screen is selected is cleared. That is, since no image is currently selected, the selection flag is cleared.

The operation reception device 300 detects the position (standing state and tilted state) of the stick 203 (step S403).
That is, for example, the detection unit 310 detects the position of the stick 203 on the XY plane based on the voltage values of the supplied analog signals of the two axes (X direction and Y direction).

The operation receiving apparatus 300 synthesizes a cursor (Step S404).
That is, the cursor synthesis unit 330 synthesizes the cursor with the corresponding display position on the selection screen generated by the screen generation unit 320 based on the position of the stick 203 detected by the detection unit 310.

The operation reception apparatus 300 determines whether any image on the selection screen has been selected (step S405).
That is, the selection unit 340 determines whether there is an image that matches the display position of the cursor synthesized on the selection screen by the cursor synthesis unit 330.
If the operation reception device 300 determines that no image is selected (step S405; No), the process proceeds to step S407 described later.

On the other hand, when it is determined that any image has been selected (step S405; Yes), the operation reception apparatus 300 sets a selection flag and selects an item associated with the image (step S406).
For example, as illustrated in FIG. 7B described above, when the cursor C2 is synthesized, the selection unit 340 selects the image SG4 (that is, defense) and the cursor C3 is synthesized. Then, the image SG2 (that is, fight) is selected.
Note that the selection unit 340 reselects a destination image when the cursor has moved to another image in a state where any image has already been selected. In other words, it is assumed that the player rotates the stick 203 while tilting, so that, for example, the stick 203 moves from the position Tm to the position Tj so as to draw an arc as shown in FIG. In this case, as shown in FIG. 7D described above, the cursor to be synthesized also moves so as to draw an arc from the cursor C3 to the cursor C4. Therefore, the selection unit 340 is indicated by the destination cursor C4. Reselect image SG3 (ie, item).

The operation reception device 300 determines whether or not the stick 203 is the base point (standing state) (step S407).
That is, it is determined whether or not the detection unit 310 has detected that the current position of the stick 203 is the base point.
If it is determined that the stick 203 is not the base point (has not returned to the base point) (step S407; No), the operation reception apparatus 300 returns the process to step S403 and repeatedly executes the above-described steps S403 to S407.

On the other hand, when it is determined that the stick 203 is the base point (returned to the base point) (step S407; Yes), the operation reception device 300 determines whether or not the selection flag is set (step S408). .
That is, it is determined whether the stick 203 is tilted and moved by the player and one of the images is selected.
If it is determined that the selection flag is not set (the flag is cleared) (step S408; No), the operation reception apparatus 300 returns the process to step S403, and repeatedly executes the processes of steps S403 to S408 described above.

On the other hand, when it is determined that the selection flag is set (step S408; Yes), the operation reception device 300 determines determination or cancellation based on the movement trajectory (step S409).
That is, the determination unit 350 determines whether the selection item is determined or canceled based on the movement trajectory when the stick 203 returns to the base point. That is, when it is specified that the stick 203 has been manually returned to the base point (by the player's operation) from the movement locus detected by the detection unit 310, the determination unit 350 determines the selected image (selection item). Is determined. On the other hand, when it is determined that the stick 203 has automatically returned to the base point (by the biasing force), the determination unit 350 determines release of the selected image.
Specifically, as shown in FIG. 8A described above, the movement trajectory when the stick 203 returns from the position Tm (tilted state) to the position C (standing position) by the player's operation exceeds a predetermined range. You will move around while moving. Since it is specified from such a movement locus that the stick 203 has manually returned to the base point, the determination unit 350 determines the determination of the selected image.
On the other hand, as shown in FIG. 8B described above, the movement trajectory when the stick 203 is returned from the position Tm to the position C by the urging force moves linearly without exceeding the predetermined range. . Since it is specified from such a movement locus that the stick 203 has automatically returned to the base point (by the biasing force), the determination unit 350 determines the cancellation of the selected image.

  If the determination has not been determined (determination has been determined) (step S410; No), the operation reception apparatus 300 returns the process to step S402 and repeatedly executes the above-described steps S402 to S410. That is, the selected state is canceled by clearing the selection flag.

On the other hand, when the determination is determined (step S410; Yes), the operation reception device 300 determines a selection item (step S411).
That is, the selection item indicated by the selected image is determined.

By such an operation determination process, after the player tilts the stick 203 with a finger and selects a desired selection item (desired image), the selection item is determined or canceled depending on how the stick 203 is handled. It can be input by switching (switching). That is, when the stick 203 is manually returned to the base point (that is, when the operator is returned with a finger), the selection item selection is input, and conversely, the stick 203 is automatically returned to the base point. When returning (that is, when a finger is released from the operation element), the cancellation of the selection item is input.
That is, the player can instruct from selection of an item to determination and release of the selected item by operating only the stick 203 without operating other buttons.
Further, after the player tilts the stick 203 and selects one of the selection items (images), the player can easily select another image by rotating the stick 203 while tilting to draw an arc. Can be redone.
As a result, the selection item can be determined and canceled more easily.

(Embodiment 2)
In the first embodiment, the case where the stick 203 is used as the operation element has been described. However, such a stick 203 is an example, and another operation element may be used. For example, even when a virtual operation element is used, it is applicable as long as the operation element automatically returns to the base point.
Hereinafter, an operation accepting apparatus according to a second embodiment of the present invention using a virtual operator will be described.

  FIG. 10 is a schematic diagram showing an external appearance of a typical game device in which the operation accepting device according to the second embodiment of the present invention is realized. As an example, the game apparatus 500 is a portable game machine, and includes a first display unit 518 and a second display unit 519 as shown in the figure, and a predetermined image is displayed on each of them. It can be displayed. Note that a touch panel 520 is provided on the front surface of the second display portion 519.

  FIG. 11 is a schematic diagram showing a schematic configuration of the game apparatus 500. Hereinafter, a description will be given with reference to FIG.

  The game apparatus 500 includes a processing control unit 510, a connector 511, a cartridge 512, a wireless communication unit 513, a communication controller 514, a sound amplifier 515, a speaker 516, operation keys 517, and a first display unit 518. And a second display portion 519 and a touch panel 520.

  The processing control unit 510 includes a CPU (Central Processing Unit) core 510a, an image processing unit 510b, a clock circuit 510c, a VRAM (Video Random Access Memory) 510d, a WRAM (Work RAM) 510e, and an LCD (Liquid Crystal Display). ) A controller 510f and a touch panel controller 510g.

  The CPU core 510a controls the overall operation of the game apparatus 500, is connected to each component, and exchanges control signals and data. Specifically, a program or data stored in a ROM (Read Only Memory) 512a in the cartridge 512 is read out in a state where the cartridge 512 is attached to the connector 511, and predetermined processing is executed.

  The image processing unit 510b processes the data read from the ROM 512a in the cartridge 512 or the data processed by the CPU core 510a, and stores the processed data in the VRAM 510d.

  The clock circuit 510c is a circuit for measuring various times (time), and measures the current time set in the game apparatus 500, the elapsed time required during the game, and the like.

The VRAM 510d is a memory that stores display information, and stores image information processed by the image processing unit 510b and the like.
The WRAM 510e stores work data and the like necessary when the CPU core 510a executes various processes according to the program.

  The LCD controller 510f controls the first display unit 518 and the second display unit 519 to display a predetermined display image. For example, the LCD controller 510f converts the image information stored in the VRAM 510d into a display signal at a predetermined synchronization timing, and outputs the display signal to the first display unit 518. Similarly, the LCD controller 510f displays a predetermined display image on the second display unit 519.

When the touch panel 520 is operated by a player's finger or the like, the touch panel controller 510g acquires the coordinates (input coordinates) and the operation content (touch operation, drag operation, etc.).
As an example, when a resistance film type touch panel 520, which will be described later, is pressed by a finger or the like, both the resistance films come into contact with each other at the pressing point, so the touch panel controller 510g displays the X-axis coordinate and Y-axis coordinate of the pressing point. A signal having a corresponding voltage is acquired. That is, the touch panel controller 510g can obtain the pressed position on the touch panel 520 by using the voltage of the acquired signal.
The touch panel controller 510g can also detect a drag operation that moves the finger while the player presses the touch panel 520 with the finger or the like.

  The connector 511 is a terminal that can be detachably connected to the cartridge 512, and transmits / receives predetermined data to / from the cartridge 512 when the cartridge 512 is connected.

The cartridge 512 includes a ROM 512a and a RAM (Random Access Memory) 512b.
The ROM 512a stores a program for realizing the game, image data and sound data associated with the game, and the like.
The RAM 512b stores various data indicating the progress of the game.

The wireless communication unit 513 is a unit that performs wireless communication with the wireless communication unit 513 of another game apparatus 500, and transmits and receives predetermined data via an antenna (not shown) (such as a built-in antenna).
Note that the wireless communication unit 513 can also perform wireless communication with a predetermined wireless access point. The wireless communication unit 513 is assigned a unique MAC (Media Access Control) address.

The communication controller 514 controls the wireless communication unit 513 and mediates wireless communication performed between the process control unit 510 and the process control unit 510 of another game device 500 in accordance with a predetermined protocol.
When the game apparatus 500 connects to the Internet via a nearby wireless access point or the like, wireless communication performed between the processing control unit 510 and the wireless access point or the like is performed according to a protocol compliant with the wireless LAN. Intermediary communication.

The sound amplifier 515 amplifies the audio signal generated by the processing control unit 510 and supplies it to the speaker 516.
The speaker 516 includes, for example, a stereo speaker and outputs predetermined music sound, sound effect, and the like according to the audio signal amplified by the sound amplifier 515.

  The operation key 517 includes a plurality of key switches and the like appropriately arranged on the game apparatus 500, and receives a predetermined instruction input according to a user operation.

The first display unit 518 and the second display unit 519 include an LCD or the like, and are controlled by the LCD controller 510f to display a game image or the like as appropriate.
Note that the second display unit 519 displays a stick image (virtual operation element) to be operated on the touch panel 520, a selection screen, and the like.
Specifically, the second display unit 519 displays a stick image 530 as shown in FIG. As an example, the stick image 530 represents a state in which the stick (stick 203) having the shape shown in FIG. The stick image 530 shows the head of the stick as a circle (more specifically, a substantially spherical shape), but the shape is arbitrary. Hereinafter, a case where the stick column part is displayed when the stick image 530 moves (tilts) will be described as an example, but the column part may not be displayed.
Such a stick image 530 is displayed (held) so as to be stationary at the base point (position C) as shown in FIG. 12B in an initial state (a state where the player has not operated the stick image). Further, the stick image 530 can be moved (tilted) in any direction of the entire circumferential direction on the operation surface when operated (when operated by the player). That is, when an operation (drag operation or the like) is performed by the player, the stick image 530 moves from position C to position Tn, position Tm, or the like, for example, as shown in FIG. To be controlled. In this state, when the player releases his / her finger from the stick image 530, the stick image 530 is controlled to return (move) at a predetermined speed to the base point (position C). In other words, when the operation of the stick image 530 is stopped (when a finger or the like is released), control is performed so that the position automatically returns from the spot to the base point.

The touch panel 520 is disposed so as to be superimposed on the front surface of the second display unit 519, and detects an operation performed by a player's finger or the like.
For example, the touch panel 520 includes a resistive film type touch sensor panel or the like. That is, two resistive films are overlapped via an insulating layer, and when an arbitrary coordinate is pressed by a player's finger or the like, information (signal or the like) corresponding to the coordinate is sequentially output. Therefore, a touch operation, a drag operation, or the like can be detected toward the stick image 530 displayed on the second display unit 519.

In such a configuration, when a cartridge 512 having a predetermined game program recorded in the ROM 512a is mounted and the game apparatus 500 is turned on, the program is executed, and the second embodiment of the present invention is applied. Such an operation receiving apparatus is realized.
Hereinafter, an operation reception device realized by such a game device 500 will be described.

(Outline of operation reception device)
FIG. 13 is a block diagram showing a schematic configuration of an operation receiving device 600 realized by the game device 500 described above. The operation receiving device 600 displays the stick image 530 on the second display unit 519 described above, receives an operation on the stick image 530 by the player (user) via the touch panel 520 described above, and selects a desired selection item. It is a device that can make decisions. Hereinafter, a description will be given with reference to FIG.

  The operation reception device 600 includes a detection unit 610, a stick image control unit 620, a screen generation unit 630, a selection unit 640, and a determination unit 650.

First, the detection unit 610 detects the position of the stick image 530 based on the voltage value of a signal supplied from the touch panel 520, for example. That is, the detection unit 610 sequentially detects the position of the stick image 530 according to the player's operation via the touch panel 520.
For example, the detection unit 610 holds a predetermined number of samplings (past) while measuring a voltage value supplied every predetermined sampling period. Therefore, when the stick image 530 is dragged (flicked), the detection unit 610, for example, as shown in FIG. 14A, each position (movement trajectory) from the position C (base point) to the position Tm. ) Is detected by the voltage value of the signal supplied from the touch panel 520. In addition, when the stick image 530 is dragged so as to draw an arc, the detection unit 610 is supplied with each position from the position Tm to the position Tj as shown in FIG. 14B, for example. Detect by the voltage value of the signal.

The detection unit 610 sequentially detects the position of the stick image 530 via the stick image control unit 620 described later when there is no operation by the player.
For example, when the player releases his / her finger from the stick image 530 dragged, the stick image control unit 620 automatically returns the stick image 530 to the base point. That is, the stick image 530 is sequentially moved from the movement destination position to the base point at a predetermined speed. Therefore, for example, the detection unit 610 sequentially detects each position from the position Tm to the position C as illustrated in FIG.
The touch panel controller 510g and the like described above can function as such a detection unit 610.

Returning to FIG. 13, the stick image control unit 620 controls the position of the stick image 530 when the stick image 530 is not operated by the player. That is, if the stick image 530 is at the base point, it is maintained as it is, and if the stick image 530 is not at the base point, control is automatically performed to return to the base point.
Specifically, the stick image control unit 620 acquires the current position of the stick image 530 when there is no operation via the touch panel 520 or when there is no operation on the stick image 530 even if there is an operation. When the current position is not equal to the base point, the current position is moved from the current position toward the base point by a predetermined distance. By repeating this at predetermined time intervals, the stick image 530 is automatically returned from the position of the movement destination to the base point.
Note that such an automatic return method is merely an example, and the stick image 530 may be moved to the base point (automatic return) by another method. For example, automatic return may be performed while changing the moving distance (moving speed) in accordance with the degree to which the position of the moving destination (current position) is away from the base point (distance to the base point). As an example, the farther away from the base point, the longer the moving distance (faster the moving speed), and conversely, the closer to the base point, the shorter the moving distance (lower the moving speed). is there.
The above-described CPU core 510a and the like can function as such a stick image control unit 620.

The screen generation unit 630 generates a selection screen including a stick image 530 and a plurality of images. That is, the screen generation unit 630 displays a stick image 530 according to the position detected by the detection unit 610, and generates a selection screen in which a plurality of images (each image indicating each selection item, etc.) are arranged around it. To do.
Specifically, as shown in FIG. 15, the screen generation unit 630 generates a selection screen in which the images SG are arranged radially from the base point (position C) of the stick image 530.
Note that the image processing unit 510b described above can function as such a screen generation unit 630.

Returning to FIG. 13, the selection unit 640 selects a selection item according to the position of the stick image 530 moved from the base point. In other words, the stick image 530 is operated by the player, and an image that matches the position of the movement destination is selected.
Specifically, as illustrated in FIG. 16A, when the stick image 530 is dragged to the position Tm by the finger F, the selection unit 640 selects the image SG2 (fight).
The selection unit 640 reselects the destination image when the stick image 530 moves to another image after any image is selected. Specifically, as illustrated in FIG. 16B, when the stick image 530 is dragged by the finger F so as to draw an arc from the position Tm to the position Tk, the selection unit 640 displays an image that matches the position Tk. Select SG1 (magic) again.
The CPU core 510a and the like described above can function as such a selection unit 640.

Returning to FIG. 13, after the selection item is selected, the determination unit 650 determines whether the selection item is determined or canceled based on the movement state when the stick image 530 returns to the base point. That is, when it is specified that the stick image 530 has been manually returned to the base point (by the player's operation) according to the movement trajectory detected by the detection unit 610 described above, the determination unit 650 selects the selected image (selection). Item) is determined. On the other hand, when it is specified that the stick image 530 has automatically returned to the base point (by control of the stick image control unit 620), the determination unit 650 determines release of the selected image.
Specifically, as illustrated in FIG. 17A, when the stick image 530 is dragged from the position Tm to the position C (base point) with the finger F, the determination unit 650 determines the determination of the selected image. To do.
On the other hand, as shown in FIG. 17B, when the stick image 530 is automatically returned from the position Tm to the position C by the control of the stick image control unit 620, the determination unit 650 determines release of the selected image. To do.
Note that the above-described CPU core 510a and the like can function as such a determination unit 650.

(Outline of operation of the operation reception device)
Hereinafter, the operation of the operation receiving apparatus 600 having such a configuration will be described with reference to the drawings. As an example, the operation of the operation accepting apparatus 600 when the player performs the selection from the selection of a desired item to the determination by operating only the stick image 530 will be described with reference to FIG. FIG. 18 is a flowchart showing a flow of operation determination processing executed by the operation reception device 600.

First, the operation reception device 600 displays a stick image and a selection screen (step S701).
That is, for example, the screen generation unit 630 generates a selection screen in which the images SG are arranged radially from the position C (base point) of the tick image 530 as shown in FIG.

  The operation reception device 600 clears the selection flag (step S702). That is, the selection flag indicating whether any image (selection item) on the selection screen is selected is cleared. That is, since no image is currently selected, the selection flag is cleared.

The operation reception device 600 detects the position of the stick image 530 (step S703).
That is, the detection unit 610 sequentially detects the position of the stick image 530 according to the player's operation via the touch panel 520, for example. Further, when there is no operation by the player, the detection unit 610 sequentially detects the position of the stick image 530 via the stick image control unit 620.

The operation reception device 600 moves the stick image 530 in accordance with the player's operation (step S704).
That is, the screen generation unit 630 changes the position of the stick image 530 based on the position of the stick image 530 detected by the detection unit 610. For example, the stick image 530 is moved according to the drag operation with the finger F as shown in FIG.

The operation reception device 600 determines whether any image on the selection screen has been selected (step S705).
That is, the selection unit 640 determines whether there is an image that matches the position (current position) of the moved stick image 530.
If the operation reception device 600 determines that no image has been selected (step S705; No), the process proceeds to step S707 described later.

On the other hand, when it is determined that any image has been selected (step S705; Yes), the operation reception device 600 sets a selection flag and selects an item associated with the image (step S706).
For example, as illustrated in FIG. 16A described above, when the stick image 530 overlaps the image SG2, the selection unit 640 selects the image SG2 (that is, fights).
Note that the selection unit 640 reselects a destination image when the stick image 530 is moved to another image in a state where any image has already been selected. That is, as shown in FIG. 16B described above, when the stick image 530 is dragged so as to draw an arc from the position Tm to the position Tk, the selection unit 640 moves the destination image SG1 (that is, magic). Select again.

The operation reception device 600 determines whether or not the stick image 530 is a base point (step S707).
That is, it is determined whether or not the detection unit 610 detects that the current position of the stick image 530 is the base point.
If it is determined that the stick image 530 is not the base point (has not returned to the base point) (step S707; No), the operation reception device 600 returns the process to step S703, and repeatedly executes the above-described steps S703 to S707.

On the other hand, when it is determined that the stick image 530 is the base point (returned to the base point) (step S707; Yes), the operation reception device 600 determines whether or not the selection flag is set (step S708). ).
That is, the stick image 530 is moved by the drag operation by the player, and it is determined whether any image is selected.
If it is determined that the selection flag is not set (the flag is cleared) (step S708; No), the operation reception device 600 returns the process to step S703, and repeatedly executes the processes of steps S703 to S708 described above.

On the other hand, when it is determined that the selection flag is set (step S708; Yes), the operation reception device 600 determines determination or cancellation based on the movement status (step S709).
That is, the determination unit 650 determines whether the selection item is determined or canceled based on the movement trajectory when the stick image 530 returns to the base point. That is, when the stick image 530 is manually returned to the base point (by the player's operation), the determination unit 650 determines the determination of the selected image (selection item). On the other hand, when it is specified that the stick image 530 has automatically returned to the base point (by the stick image control unit 620), the determination unit 650 determines release of the selected image.
Specifically, as shown in FIG. 17A described above, when the stick image 530 is returned from the position Tm to the position C (base point) by the player's operation, the determination unit 650 determines the selected image. Is determined.
On the other hand, as shown in FIG. 17B described above, when the stick image 530 is returned from the position Tm to the position C by the control of the stick image control unit 620, the determination unit 650 determines release of the selected image. To do.

  If the determination has not been determined (determination has been determined) (step S710; No), the operation accepting apparatus 600 returns the process to step S702, and repeatedly executes the processes of steps S702 to S710 described above. That is, the selected state is canceled by clearing the selection flag.

On the other hand, when the determination is determined (step S710; Yes), the operation reception apparatus 600 determines the selection item (step S711).
That is, the selection item indicated by the selected image is determined.

By such an operation determination process, after the player moves the stick image 530 with a finger and selects a desired selection item (desired image), the selection item can be determined or determined depending on how the stick image 530 is handled. You can input (switch) the release. That is, when the stick image 530 is manually returned to the base point (that is, when the operator is returned with a finger), the selection of the selection item is input, and conversely, the stick image 530 is automatically displayed. When returning to the base point (that is, when the finger is released from the operation element), the cancellation of the selection item is input.
That is, the player can instruct from selection of an item to determination and release of the selected item by operating only the stick image 530 without operating other buttons or the like.
Further, after the player moves the stick image 530 and selects one of the selection items (images), the player drags the stick image 530 to draw an arc, thereby easily selecting another image. be able to.
As a result, the selection item can be determined and canceled more easily.

(Other embodiments)
In the first and second embodiments described above, after the selection item (image) is selected, the selection is determined when the stick 203 or the like (the stick 203 or the stick image 530) is manually returned to the base point, On the other hand, although the case where the selection is canceled when the stick 203 or the like is automatically returned to the base point has been described, the determination of the selection and the assignment of the cancellation are examples, and these may be switched as appropriate.
That is, the selection may be determined when the stick 203 or the like is automatically returned to the base point, and the selection may be canceled when the stick 203 or the like is manually returned to the base point.

In the above-described embodiment, the case where the factor that the stick 203 or the like has returned to the base point has been described mainly based on the movement trajectory. However, the factor that returned to the base point may be determined by another method. Good.
For example, the factor that returned to the base point may be determined based on speed, acceleration, or the like. That is, the speed and acceleration at the time when the stick 203 or the like returns from the position of the movement destination to the base point are sequentially measured, and it is determined from the change of the speed or acceleration whether the recovery is performed manually or automatically.
Specifically, the operation accepting device 300 of FIG. 3 described above will be described as an example. When the stick 203 returns to the base point by the biasing force, a motion equivalent to a simple vibration of the spring is performed. Therefore, the change in the measured speed is represented by a graph as shown in FIG. Moreover, the change of the measured acceleration is represented with a graph as shown in FIG.19 (b).

Therefore, the detection unit 310 sequentially measures the speed and acceleration when the stick 203 returns from the movement destination to the base point. Then, the determination unit 350 determines that the factor returning to the base point is due to the urging force (automatic return) when the measured speed and acceleration change as shown in FIGS. 19A and 19B. To do. On the other hand, when the measured speed or acceleration changes unlike FIGS. 19A and 19B, the determination unit 350 determines that the cause of the return to the base point is manual.
That is, in the case of manual operation, the measured speed or acceleration is not represented as a curve as shown in FIGS. 19A and 19B, so it is determined whether the return is due to the urging force (automatic) or not (manual). can do.

  As described above, according to the present invention, it is possible to provide an operation reception device, an operation determination method, and a program that can more easily perform operations such as determination of selection items.
