  By the way, as an operation method peculiar to the touch operation, there is an operation (hereinafter referred to as “sliding operation”) in which a pen, a finger, or the like is moved on the display while being in contact therewith. As an input using a sliding operation, for example, handwritten character input in which an input locus is directly used as an input character is generally used. However, in the sliding operation, it is possible to input various elements such as the shape and length of the movement trajectory, and the operation speed (speed to move while in contact). Is it possible to realize a new input operation using a sliding operation including such various input elements? The present invention has been made in view of this point.

In order to solve the above problem, the first invention is:

It is an electronic device characterized by including.

  According to the first or sixteenth invention, the virtual space image in which the moving body moves is generated and controlled, and the sliding operation with respect to the input operation area formed on the display unit is detected, and the detected sliding is detected. The movement of the moving body can be controlled based on the moving operation. Accordingly, it is possible to realize a new input operation in which an input operation for controlling the moving direction and moving speed of the moving body moving in the virtual space is performed by a sliding operation on the display unit.

  In this case, since the guide body representing at least one of the moving direction and moving speed of the moving body can be variably displayed based on the detected sliding operation, the moving direction and moving speed of the moving body in the virtual space It is possible to make the user easily understand visually. The user can perform a sliding operation while referring to the grasped moving direction and moving speed. For this reason, it becomes possible to improve the operativity in the case of sliding operation.

The variable amount of movement of the moving body can be reduced in the low speed region and the high speed region of the changeable region, and the variable amount can be increased in the medium speed region. That is, even when the same sliding operation is performed, for example, when the moving body is to start moving from a state where it is stationary (stopped) (corresponding to the low speed range), the moving body moves to a certain degree. It is possible to realize the same movement control as that of an object in the real world such that the moving speed does not increase easily compared with the case where the moving speed is equivalent to that in the middle speed range. Therefore, when starting the movement of a stationary (stopped) object, a larger force can be applied by, for example, performing a sliding operation more times than when the object is moving at a certain speed. It is possible to express operability as if a moving body having a mass is actually operated, such as having to act.

In the following, the case where the present invention is applied to a portable game device which is a kind of electronic device will be described, but the application of the present invention is not limited to this.

[appearance]
FIG. 1 is an external view of a game apparatus 1 according to the present embodiment. According to the figure, the game apparatus 1 includes a display 2, an operation key 4, and a speaker 5 on the front surface of a substantially rectangular parallelepiped casing, and the game apparatus 1 on the upper side surface of the casing. A slot 6 is provided for mounting a cartridge 7 which is a detachable information storage medium. Although not shown on the side of the housing, a power switch for turning on / off the power of the game apparatus 1, a volume switch for adjusting the output sound of the speaker 5, other game apparatuses 1, etc. A communication device for performing wireless / wired communication by connecting to an external device is provided.

  The display 2 is a color liquid crystal display such as a TFT display, and as shown in FIG. 2, a touch panel 3 is integrally formed over the entire upper surface (or lower surface) of the liquid crystal layer. The touch panel 3 detects a touched position on the display 2 by, for example, a dot unit constituting the display 2 by a detection principle such as a pressure-sensitive type, an optical type, an electrostatic type, or an electromagnetic induction type. ) P signal (touch operation signal) is output. The touch position P is expressed by a coordinate system set on the display 2. The player can perform various operation inputs by a touch operation on the display 2 using the attached stylus pen 8 or a finger.

  In addition, a control unit equipped with a CPU, an IC memory, and the like is built in the housing. The CPU executes various game processes based on the program and data read from the IC memory and the cartridge 7, the operation signal input from the operation key 4, the touch operation signal input from the touch panel 3, and the like. The sound signal of the signal and the game sound is generated. Then, the generated image signal is output to the display 2 to display the game screen, and the sound signal is output to the speaker 5 to output the game sound.

  Information necessary for the game apparatus 1 to execute a game (system program, game program, game data, etc.) is stored in an IC memory mounted on a control unit in the housing or a cartridge that is detachable from the game apparatus 1. 7 is stored. More specifically, the system program is stored in an IC memory mounted on the control unit, and the game program and game data are stored in the cartridge 7. Accordingly, the player can cause the game apparatus 1 to execute a different game by exchanging the cartridge 7.

  By the way, in the game apparatus 1, a touch operation can be performed on the entire surface of the display 2, but depending on the game to be executed, for example, as shown in FIG. This is set as the input area 3A (more accurately, recognized as an effective touch operation input). Setting information for setting the input area 3A is stored in the cartridge 7 together with the game program as part of the game data. In the game apparatus 1, before the game is executed, the input area 3 </ b> A is set on the touch panel 3 according to the setting information included in the game information (game program and game data) read from the cartridge 7 mounted in the slot 6. Game processing is executed in accordance with the read game program or the like.

  In the present embodiment, as shown in FIG. 4, the display 2 displays a game screen GW in the upper area and a virtual trackball screen TW in the lower area. Then, the part of the touch panel 3 corresponding to the virtual trackball screen TW is set as the input area 3A. Then, the player performs a touch operation input on the virtual trackball screen TW at the bottom of the display 2.

[Game screen]
On the game screen GW, an image (3DCG image) of the game space obtained by viewing the game space, which is a virtual three-dimensional space, from the viewpoint of a given virtual camera or the like is displayed.

FIG. 5 is a diagram illustrating an example of the game space. According to the figure, in the game space, a passage object (hereinafter simply referred to as “passage”) PS arranged so as to float in the air, an operation target character CA that is a moving body that moves in the game space, and A virtual camera CM1 is arranged. The game space is defined by a coordinate system (game space coordinate system) (X _W , Y _W , Z _W ) with the X _W -Z _W plane as a horizontal plane, and is predetermined in the Y _W axis negative direction (vertical downward direction). It is a gravitational field where the gravity G works.

  The player moves the operation target character CA on the path PS from the start point provided on the path PS to the goal point. When the operation target character CA reaches the goal point, the game is “successful”, and when the operation target character CA falls off the passage PS or when a predetermined time limit elapses, the game becomes “game failure”. The operation of moving the operation target character CA is performed by a touch operation (hereinafter referred to as “sliding touch operation”) in which the stylus pen 8 or a finger is moved in contact with the display 2 on the virtual trackball screen TW. Do.

  The passage PS is formed by combining, for example, plate-like objects. In the passage PS, in addition to a horizontal, flat and smooth portion (smooth portion), the inclined portion PS1, a convex and concave portion PS2 whose upper surface is uneven, a wide or narrow portion, a portion which is slippery and hard to stop, such as on ice, etc. There are various aspects of the situation (hereinafter collectively referred to as “passage state etc.”), and the configuration is varied. For this reason, for example, when the player goes down the inclined portion PS1, the state of the passage PS at the current position of the operation target character CA is such that the acceleration is easier than the flat portion, so that the speed is reduced. Appropriate operations must be performed in consideration of the above.

  The operation target character CA is a sphere object as shown in FIG. Further, the operation target character CA has a direction, and is arranged in the game space so that the direction coincides with the movement direction. Then, the operation target character CA moves while rotating in the forward direction (the direction indicated by the arrow AR1 in the drawing) toward the movement direction. When changing the moving direction, the moving direction is controlled after changing the direction to the moving direction to be changed. The operation target character CA rotates only in one direction and does not rotate in any other direction.

  Further, a striped pattern is drawn on the surface of the operation target character CA, and the direction of the operation target character CA can be visually grasped by this striped pattern. In the figure, stripes are drawn so as to be substantially perpendicular to the direction of the operation target character CA. Therefore, the player can easily determine that the direction substantially perpendicular to the stripe is the direction of the operation target character CA, that is, the moving direction.

The virtual camera CM1 is arranged so as to follow the operation target character CA so as to look down from a position obliquely above the operation target character CA in the game space. More specifically, the operation target character CA is positioned approximately in the center of the field of view, and the distance between the virtual camera CM1 and the operation target character CA is constant. The line-of-sight direction is fixed in a direction parallel to the Y _W -Z _W plane and looking down from above. The state of the game space viewed from the virtual camera CM1 is displayed on the display 2 as a game screen GW.

Therefore, the game screen GW has a composition in which the game space is looked down obliquely from above, as shown in FIG. In the figure, the left side shows the game screen GW, and the right side shows the game space at that time. On the game screen GW, the operation target character CA is always displayed at substantially the same size in the approximate center thereof. Further, since the viewing direction of the virtual camera CM1 is fixed, the direction of the game space on the game screen GW is always constant. That is, since the line-of-sight direction of the virtual camera CM1 is fixed parallel to the Z _w -Y _W plane, upward direction of the game screen GW matches the Z _W-axis positive direction, the right direction and X _W axis positive direction one- I'm doing it.

When the movement direction (direction) of the operation target character CA in the game space changes, the movement direction (direction) of the operation target character CA on the game screen GW also changes in response to the change. Specifically, as shown in FIG. 5A, when the operation target character CA is moving in the positive direction of the Z _W axis in the game space (the moving direction is the positive direction of the Z _W axis), the game The movement direction of the operation target character CA on the screen GW is upward. Then, as shown in FIG. 5B, when the movement direction of the operation target character CA in the game space changes to the _XW axis negative direction, the movement direction of the operation target character CA on the game screen GW changes to the left.

[Virtual trackball screen]
The virtual trackball screen TW displays an image (3DCG image) obtained by viewing the virtual trackball space, which is a three-dimensional virtual space, from the line of sight of a given virtual camera or the like.

FIG. 8 is a diagram illustrating an example of a virtual trackball space. According to the figure, a virtual trackball TB and a virtual camera CM2 are arranged in the virtual trackball space. The coordinate system (virtual trackball space coordinate system) (X _T , Y _T , Z _T ) that defines the virtual trackball space is set in parallel with the game space coordinate system (X _W , Y _W , Z _W ). ing.

The virtual trackball TB is a spherical object that is a kind of rotating body. The virtual track ball TB is the center O as the origin, the orientation model coordinate system which coincides with z _t-axis positive direction (virtual trackball model coordinate _{system) (x t, y t,} z t) is defined by, x _t -z _t planes are placed in the virtual track ball space so that parallel and y _t-axis positive direction and the horizontal plane (X _T -Z _T plane) coincides with Y _T axis positive direction. Then, the virtual track ball TB is an axis about the x _t-axis, (in the figure, the direction indicated by the arrow AR2) left direction around the x _t-axis positive direction is rotated to. Further, the virtual trackball TB does not move (the position of the center O does not change). That is, in the virtual track ball space, a virtual trackball TB rotates while changing its direction (z _t-axis positive direction) of the center O as fixed.

Further, on the surface of the virtual trackball TB, for example, a plurality of thin decorative lines corresponding to meridians virtually set on the surface of the earth are drawn, and the orientation of the virtual trackball TB is visually indicated by the decorative lines. It is possible to grasp. In the figure, a decoration line is drawn so as to connect two points (corresponding to poles) where the surface of the virtual trackball TB and the _xt axis intersect. That is, the decoration line is drawn so as to be orthogonal to the direction of the virtual trackball TB.

  The virtual camera CM2 is fixedly disposed above the virtual trackball TB in the virtual trackball space. Specifically, the line-of-sight direction is a vertically downward direction passing through the center O of the virtual trackball TB, and the virtual trackball TB is disposed at a position where the virtual trackball TB falls within the approximate center of the field of view. Then, the state of the virtual trackball space viewed from the virtual camera CM2 is displayed on the display 2 as a virtual trackball screen TW.

Therefore, the virtual trackball screen TW has a composition in which the virtual trackball TB is looked down from directly above, as shown in FIG. In the figure, the left side shows the virtual trackball screen TW, and the right side shows the virtual trackball space at that time. Virtual trackball screen TW is right direction coincides with the X _T axis positive direction, the upward direction is generated to match the Z _T axis positive direction. Further, since the position of the virtual trackball TB in the virtual trackball space is fixed, and the position and the viewing direction of the virtual camera CM2 are fixed, the position of the virtual trackball TB on the virtual trackball screen TW (the center O) Position) is fixed.

Then, when the direction and the rotation speed of the virtual trackball TB in the virtual trackball space change, the direction of the virtual trackball TB on the virtual trackball screen TW (rotates in this direction corresponding to the change). This is referred to as the “rotation direction”) and the rotation speed also changes. Specifically, as shown in FIG. 6 (a), in the virtual track ball space, arranged so that the orientation of the virtual track ball TB (z _t-axis positive direction) forms an angle of 45 degrees with respect to Z _T axis In this case, the direction of the virtual trackball TB on the virtual trackball screen TW is the upper right direction, and is displayed so as to rotate from the lower left toward the upper right. That is, the rotation direction is the upper right direction. As shown in FIG. 5B, when the direction of the virtual trackball TB in the virtual trackball space changes in the positive direction of the _XT axis, the rotation direction of the virtual trackball TB on the virtual trackball screen TW becomes the right direction. Change.

  The virtual trackball TB is a guide body that represents the moving direction and moving speed of the operation target character CA, and its direction and rotation speed are controlled according to the moving direction and moving speed of the operation target character CA in the game space. . Specifically, the direction (rotation direction) of the virtual trackball TB represents the movement direction of the operation target character CA, the rotation speed represents the movement speed, and the virtual trackball TB when the movement direction of the operation target character CA changes. When the direction of rotation (rotation direction) changes and the movement speed changes, the rotation speed is controlled to change.

  In the present embodiment, as shown in FIG. 10, the rotation direction of the virtual trackball TB on the virtual trackball screen TW substantially coincides with the moving direction of the operation target character CA on the game screen GW, and the virtual trackball screen TW Control is performed so that the rotation speed of the virtual trackball TB is substantially proportional to the movement speed of the operation target character CA.

  That is, in FIG. 5A, the movement direction of the operation target character CA on the game screen is the upper right direction, and the rotation direction of the virtual trackball TB on the virtual trackball screen TW is also the upper right, which are almost the same. As shown in FIG. 4B, when the movement direction of the operation target character CA on the game screen GW changes to the upper left direction, the rotation direction of the virtual track ball TB on the virtual track ball screen TW also changes to the upper left direction. To change. When the movement speed of the operation target character CA on the game screen GW is increased as it is, the rotation speed of the virtual trackball TB on the virtual trackball screen TW is also increased without changing the rotation direction.

  Further, on the virtual trackball screen TW, as shown in FIG. 11, in addition to the image of the virtual trackball space viewed from the virtual camera CM2 (that is, the image of the virtual trackball TB), the moving display which is another guide body is displayed. The field EX is displayed. The movement display body EX is shaped like an arrow, the direction (direction) of the arrow represents the movement direction of the operation target character CA, and the length represents the movement speed.

  Specifically, the movement display body EX is displayed so that the direction (direction) thereof substantially coincides with the movement direction of the operation target character CA on the game screen GW. That is, the rotation direction (that is, the direction) of the virtual trackball TB on the virtual trackball screen TW matches the direction (direction) of the moving display body EX. Further, the length of the moving display body EX is displayed with a length substantially proportional to the moving speed of the operation target character CA on the game screen GW. That is, as the moving speed of the operation target character CA increases, the length of the moving display body EX increases. Note that when the moving speed of the operation target character CA in the game space is “0” (still), the moving display body EX is “0” and is not displayed.

  The player performs a sliding touch operation so as to roll the virtual trackball TB displayed on the virtual trackball screen TW. Then, the operation target character CA and the virtual trackball TB are controlled according to the direction (sliding operation direction) and the operation amount (sliding operation amount) of the performed sliding touch operation, and the game screen GW and the virtual trackball screen are controlled. The display of TW changes.

[Operation example]
12 and 13 are diagrams showing examples of operations.
As shown in FIG. 12A, when the operation target character CA on the game screen GW and the virtual trackball TB on the virtual trackball screen TW are both stationary (stopped), as shown in FIG. Then, a sliding touch operation in the upper right direction is performed on the virtual trackball screen TW. In FIG. 9A, since the operation target character CA is stationary, the moving display body EX is not displayed on the virtual trackball screen TW. Then, the game screen GW and the virtual trackball screen TW change according to this sliding touch operation, as shown in FIG.

  That is, on the game screen GW, the operation target character CA changes its direction in a direction substantially coinciding with the sliding operation direction, and starts moving with the direction along the sliding operation direction as the moving direction. On the virtual trackball screen TW, the virtual trackball TB starts to rotate with the direction along the sliding operation direction as the rotation direction, and moves along the direction (direction) along the direction of the sliding operation. The display body EX is displayed.

  When the sliding touch operation in the same direction (that is, the upper right direction) is further repeated a plurality of times continuously on the virtual trackball screen TW in the state of FIG. The moving speed of CA increases in the direction and the moving direction. Further, the rotation speed of the virtual trackball TB on the virtual trackball screen TW increases in the rotation direction as it is, and the length of the moving display body EX becomes longer in the direction (direction) as it is.

  Further, as shown in FIG. 13A, the operation target character CA moves in the game screen GW with the upper right direction as the movement direction, and the virtual track ball TB rotates in the virtual track ball screen TW with the upper right direction as the rotation direction. At the same time, with the moving display body EX displayed in the direction (direction) in the upper right direction, a sliding touch operation in the upper left direction is performed as shown in FIG. Then, as shown in FIG. 6C, the direction and movement direction of the operation target character CA on the game screen GW, the rotation direction of the virtual trackball TB on the virtual trackball screen TW, and the direction (direction) of the movement display body EX. Both of them change slightly toward the sliding operation direction.

  That is, on the game screen GW, the direction and the moving direction of the operation target character CA are changed slightly upward toward the left. In the virtual trackball screen TW, the rotation direction of the virtual trackball TB changes slightly upward to the left, and the direction (direction) of the moving display body EX also changes upward to the left. . Of course, in this case, the moving direction of the operation target character CA on the changed game screen GW substantially coincides with the rotation direction of the virtual trackball TB and the direction (direction) of the moving display body EX on the virtual trackball screen TW. .

  Thus, in this embodiment, the operation target character CA and the virtual trackball TB are controlled in accordance with the sliding touch operation performed. Specifically, the movement direction of the operation target character CA on the game screen GW and the rotation direction of the virtual trackball TB on the virtual trackball screen TW change toward the sliding operation direction, and the movement speed of the operation target character CA is increased. In addition, the rotation speed of the virtual trackball TB is controlled to change by a speed corresponding to the sliding operation amount.

  Further, the rotation direction of the virtual trackball TB and the direction (direction) of the movement display body EX on the virtual trackball screen TW represent the movement direction of the operation target character CA, and the rotation speed of the virtual trackball TB and the length of the movement display body EX. Since this represents the moving speed of the operation target character CA, the player can operate the operation target character while referring to the rotation direction and rotation speed of the virtual trackball TB and the direction (direction) and length of the moving display body EX as a guide. A sliding touch operation for moving the character CA can be performed. For example, when it is desired to increase the moving speed without changing the moving direction of the operation target character CA, the sliding touch operation is performed in the direction along the rotation direction of the virtual trackball TB and the moving display body EX on the virtual trackball screen TW. In addition, when it is desired to move the operation target character CA in the direction opposite to the current movement direction, a sliding touch operation may be performed along the direction opposite to the rotation direction of the virtual trackball TB.

[principle]
The control principle of the operation target character CA and the virtual trackball TB based on the sliding touch operation will be described.

  The game apparatus 1 captures the touch position P detected by the touch panel 3 every predetermined unit time Δt (for example, one frame), and detects a touch operation input based on the captured touch position P. Further, while the sliding touch operation is performed, the touch position P detected by the touch panel 3 changes one after another. For this reason, in this embodiment, if different touch positions P are taken in successively, it is determined that a sliding touch operation has been detected. When a sliding touch operation is detected, an input vector a corresponding to the sliding touch operation is calculated based on the captured touch position P, and the operation target character CA is controlled based on the calculated input vector a. At the same time, the virtual trackball TB is controlled based on the movement of the operation target character CA.

<Control of the operation target character>
FIG. 14 is a diagram for explaining the calculation of the input vector a. As shown in FIG. 5A, when a sliding touch operation is performed on the virtual trackball screen TW, the touch position P detected by the touch position P is taken every predetermined unit time Δt. For example, as shown in FIG. (B), the touch position P ₀ at time t ₀ is taken, disparate touch location P ₁ and the touch position P ₀ at time t ₁ the unit time Δt has elapsed from time t ₀ is It is captured. Then, it is determined that the sliding touch operation has been detected, and the vector having the touch position P ₀ as the start point and the touch position P ₁ as the end point is the sliding touch operation detected between time t ₀ and time t _1. Calculated as the corresponding input vector a.

The magnitude of the input vector a represents the operation amount of the sliding touch operation (sliding operation amount; the length between P ₀ and P ₁ ), which is a change in the touch position P per unit time Δt. That is, this corresponds to the speed of the sliding touch operation (the speed at which the display 2 is moved while the stylus pen 8 or the finger is in contact therewith). That is, the faster the sliding touch operation, the larger the sliding operation amount per unit time Δt. Further, the direction (direction) of the input vector a represents the operation direction (sliding operation direction) of the sliding touch operation. In FIG. 5B, the sliding operation direction of the sliding touch operation represented by the input vector a is the upper right direction.

Here, as described above, the virtual trackball screen TW is a screen displaying a state in which the virtual trackball space is seen from directly above, and the right direction is the _XT axis positive direction and the upward direction is Z _T. It matches the positive axis direction. For this reason, the input vector a is expressed as a vector parallel to the X _T -Z _T plane while being expressed in the virtual trackball space coordinate system (X _T , Y _T , Z _T ).

  When the input vector a is calculated, it is considered that a force corresponding to the calculated input vector a is applied, and the movement of the operation target character CA in the game space is controlled.

  In this embodiment, as shown in FIGS. 7 and 9, the right direction of each screen of the game screen GW and the virtual trackball screen TW coincides with the positive X-axis direction of the spatial coordinate system on each screen, The upper direction of each screen coincides with the positive direction of the Z axis on each screen. That is, the coordinate directions of the display coordinate systems of the game screen GW and the virtual trackball screen TW coincide with each other. Further, the moving direction of the operation target character CA on the game screen and the rotation direction of the virtual trackball TB on the virtual trackball screen TW are displayed so as to substantially match. Therefore, the input vector a detected and calculated on the virtual trackball screen TW can be applied to the game space without converting the coordinate system.

In the present embodiment, the movement of the operation target character CA in the game space is expressed by a movement vector V. As shown in FIG. 15, the direction (direction) of the movement vector V coincides with the movement direction of the operation target character CA, and the magnitude of the movement vector V is substantially proportional to the movement speed V _c .

The movement vector V at time t _1, as shown in FIG. 16, as shown in the following equation (1), a moving vector V ₀ in (A) the time t _0, is given (B) input vector a This is calculated as a combined vector of the input action vector A generated by this and (C) the external force vector F generated by the terrain condition and the environmental condition. .
V = V ₀ + A + F (1)

The input action vector A is given by the following equation (2).
A = f (| V ₀ |) × a (2)

As shown in the above equation (2), the input action vector A is an input action determining function f (| V ₀ |) whose parameter is the magnitude | V ₀ | of the movement vector V ₀ and the input vector a. Is given as a product.

The input action determination function f is a function for adjusting the magnitude of the input action vector A. FIG. 17 shows an example of the input action determination function f (| V ₀ |). In the figure, a graph is shown in which the horizontal axis is the magnitude | V ₀ | of the movement vector V ₀ and the vertical axis is the value of the input action determining function f.

According to the figure, the input action determining function f has the movement vector V _{0 in} the low speed range where the magnitude | V ₀ | is relatively small (moving speed is slow) and in the high speed range where the moving speed is high (fast moving speed). magnitude of V ₀ | V ₀ | large change in the value of the input action decision function f to a change in, the magnitude of the movement vector V ₀ | V ₀ | among moderate speed range, the movement vector V ₀ The change in the value of the input action determination function f with respect to the change in the magnitude | V ₀ |

That is, even when the input vectors a are the same, when the magnitude of the movement vector V ₀ , that is, the movement speed V _c0 of the operation target character CA at time t ₀ is relatively slow (small) or fast (large), The magnitude of the input action vector A is smaller than that when the moving speed V _c0 is medium. That is, even when the same sliding touch operation is performed, when the movement speed V _c of the operation target character CA is relatively slow or fast, the amount of change in the movement speed V _c becomes small, while the movement speed When the speed V _c is medium, the amount of change in the moving speed V _c becomes large.

  The input action determination function f is set according to physical parameters such as the mass Mc and the radius Rc of the operation target character CA. According to the laws of physics, even when the same force is applied, as the mass Mc of the operation target character CA that is a sphere is larger (heavy) or as the radius Rc is larger (long), the operation target character is larger. The moving speed generated in CA is small (slow). For this reason, the input action determination function f is set so that the value decreases as the mass M of the operation target character CA increases or the radius Rc increases.

Thus, the orientation (direction) of the input action vectors A matches the direction (direction) of the input vector a, the size is a value corresponding to the size and magnitude of the movement vector V ₀ which input vector a.

  The external force vector F is a vector generated by the terrain of the game space or the environmental force that affects the movement of the operation target character CA. FIG. 18 shows an example of setting the external force vector F. As shown in the figure, an external force vector F1 corresponding to a frictional force generated between the operation target character CA and the upper surface of the passage PS is applied in a direction opposite to the movement direction of the operation target character CA (the direction of the movement vector V). . The value of the external force vector F1 corresponds to the state of the upper surface of the passage PS at the current position of the operation target character CA, for example, such that the convex and concave portion PS2 is larger than the smooth portion, and the mass of the operation target character CA. It also depends on Mc. Further, when the current position of the operation target character CA is the inclined portion PS1, the external force vector F2 corresponding to the inclination angle caused by gravity is applied. When wind is set in the game space, an external force vector F3 corresponding to the magnitude of wind force is applied along the wind direction.

When the movement vector V is calculated, the calculated movement vector V is further optimized so that the magnitude does not exceed the maximum movement speed V _cmax of the operation target character CA set according to the nature of the game. Is done.

Next, based on the optimized movement vector V, as shown in FIG. 19, the position and posture of the operation target character CA at time t ₂ after the unit time Δt has elapsed from time t ₁ are determined.

Specifically, the movement distance L _c of the operation target character CA during the unit time Δt from time t ₁ to time t ₂ is represented by the magnitude | V | of the movement vector V as shown in the following equation (3). It is calculated as the product of the moving distance calculating coefficient k _c1 and.
L _c = | V | × k _c1 (3)

Further, the rotation angle θ _c of the operation target character CA during the unit time Δt from time t ₁ to time t ₂ is represented by the magnitude | V | of the movement vector V and the rotation angle as shown in the following equation (4). It is calculated as the product of the calculated coefficient k _c2.
θ _c = | V | × k _c2 (4)

Then, from the calculated moving distance L _c and rotation angle θ _c , the position and posture of the operation target character CA at time t ₂ are determined. Specifically, the position moved by the movement distance L _{c in the} direction along the direction (direction) of the movement vector V from the position of the operation target character CA at time t ₁ is set as the position at time t ₂ . In addition, the orientation of the operation target character CA is made to coincide with the direction (direction) of the movement vector V, and the posture rotated by the rotation angle θ _c from the posture of the operation target character CA at time t ₁ is set as the posture at time t ₂ . .

Thus, the movement vector V ₀ at time t _0, by synthesizing an input action vector A based on the sliding touch operation between time t ₀ of time t _1, the velocity vector V is calculated at time t ₁ The That is, the moving direction and moving speed of the operation target character CA at time t ₁ are calculated by adding the speed corresponding to the sliding operation amount in the direction along the operation direction of the sliding touch operation. Further, when the sliding touch operation is not detected, A = 0 in Expression (1). In other words, the magnitude of the movement vector V ₀ is controlled by the external force vector F 1 corresponding to the friction force acting in the direction opposite to the movement direction of the operation target character CA included in the external force vector F.

Therefore, for example, when the operation target character CA is stationary (stopped), the operation target character CA when the same sliding touch operation (sliding operation direction and sliding operation amount is the same) is continuously repeated. The moving speed changes as shown in FIG. This graph is a graph showing an example of a change in the movement speed V _c of the operation target character CA with respect to time t, where the horizontal axis is time t and the vertical axis is the movement speed V _c of the operation target character CA. According to the figure, while the sliding touch operation is continuously performed, the moving speed _Vc gradually increases with time.

Specifically, immediately after the start of the sliding touch operation (during the first to several sliding touch operations; corresponding to the low speed range), the value of the input action determination function f is as shown in FIG. Since it is small, the size of the input action vector A is small, and the moving speed V _c does not increase easily. Perform sliding touch operation several times, (corresponding to medium speed range) when increased to a certain speed moving velocity V _c, the size becomes large input action vector A value of the input action determination function f is increased, The increase in the moving speed V _c becomes large. When the moving speed V _c further increases (corresponding to the high speed range), the value of the input action determining function f decreases again, the size of the input vector A decreases, the increase in the moving speed V _c decreases, and the movement When the speed V _c reaches a predetermined maximum moving speed V _cmax , it does not increase any more. Thereafter, when the sliding touch operation is terminated at time t _n , the input action vector A becomes “0”, so the moving speed V _c gradually decreases and finally decreases to “0” (still (stop (stop) )).

<Control of virtual trackball>
Since the virtual trackball TB is controlled to perform rotation reflecting the movement of the operation target character CA, the virtual trackball TB is controlled based on the movement vector V calculated for the operation target character CA.

  That is, although the movement vector V of the operation target character CA is applied to the virtual trackball space, in the present embodiment, as described above, the coordinate direction of the display coordinate system on the game screen GW and the virtual trackball screen TW is They are displayed so as to match each other, and the moving direction of the operation target character CA on the game screen GW and the rotation direction of the virtual trackball TB on the virtual trackball screen TW are substantially matched. Therefore, the movement vector V expressed in the game space coordinate system can be applied to the virtual trackball space without converting the coordinate system.

Specifically, as shown in FIG. 21, the attitude of the virtual trackball TB at time t ₂ is determined based on the movement vector V. That is, the rotation angle θ _t of the virtual trackball TB during the unit time Δt from the time t ₁ to the time t ₂ is _expressed by the magnitude of the movement vector V and the rotation angle determination coefficient k _t as shown in the following equation (5). As a product of
θ _t = | V | × k _t (5)

Then, to match the orientation direction of the movement vector V (direction), and the attitude of the virtual track ball rotation is calculated from the attitude of TB angle theta _t time was rotated position by t ₂ at time t _1.

[Function configuration]
FIG. 22 is a block diagram showing a functional configuration of the game apparatus 1 in the present embodiment. According to the figure, the game apparatus 1 functionally includes an operation input unit 10, a processing unit 20, an image display unit 30, an audio output unit 40, and a storage unit 50. Yes.

This function is realized by, for example, an arithmetic device such as a CPU (CISC type, RISC type), ASIC (gate array, etc.) or a control program thereof. In FIG. 1, the CPU mounted on the control unit built in the game apparatus 1 corresponds to this.

The display area 34 is set. Then, the area of the touch panel 3 corresponding to the set virtual trackball screen TW is set as the input area 3A.

The sliding touch operation detection unit 214 detects a sliding touch operation based on the touch position P input from the touch panel 3, and calculates an input vector a corresponding to the detected sliding touch operation. Specifically, if the touch position P detected by the touch panel 3 is captured for each frame and the touch position P is captured continuously with the previous frame and the current frame, the touch position P ₀ captured with the previous frame is the starting point. and then, an input vector a and calculates the vector and ending the touch position P ₁ taken in the current frame. If the touch position P is not captured continuously for two frames, it is determined that the sliding touch operation is not detected, and the input vector a is not calculated.

  The touch position P captured by the sliding touch operation detection unit 214 and the calculated input vector a are stored in the input vector calculation data 542. FIG. 23 shows an example of the data configuration of the input vector calculation data 542.

Vector F is calculated. Further, the value obtained by substituting the magnitude of the movement vector V ₀ in the previous frame into the input action determination function f to the input vector a calculated by the sliding touch operation detection unit 214 according to the equation (2). Let the multiplied vector be the input action vector A. The input action determination function f used here is stored in the operation target character data 536.

Then, according to equation (1), the movement vector V ₀ in the previous frame, the input action vector A, and the external force vector F are added (synthesized) to calculate the movement vector V in the current frame. When the input vector a is not calculated, that is, when the sliding touch operation is not detected, the movement vector V is calculated as A = 0 in the equation (1).

Here, the movement distance calculation coefficient k _c1 used for calculating the movement distance L _c and the rotation angle calculation coefficient k _c2 used for calculating the rotation angle θ _c are stored in the operation target character data 536. Next, the position moved by the movement distance L _{c in the} direction matching the direction (direction) of the movement vector V from the position of the operation target character CA in the current frame is set as the position in the next frame. In addition, the orientation of the operation target character CA is made to coincide with the orientation (direction) of the movement vector V, and the posture rotated by the rotation angle θ _c from the current posture is set as the posture in the next frame. Then, the operation target character CA is rearranged in the game space at the determined position / posture.

The virtual trackball control unit 222 controls the virtual trackball TB based on the movement vector V calculated by the movement vector calculation unit 216. Specifically, according to Equation (5), calculates a rotation angle theta _t virtual trackball TB between the current frame to the next frame. Here, the rotation angle calculation coefficient k _t used for calculating the rotation angle θ _t is stored in the virtual trackball data 538. Then, the posture of the to match the orientation of the virtual track ball TB (z _t-axis positive direction) in the direction of the movement vector V (direction), the posture is rotated by the rotation angle theta _t from the orientation of the current frame in the next frame To do. Then, the virtual trackball TB is rearranged in the virtual trackball space with the determined posture without changing the position.

[Process flow]
FIG. 27 is a flowchart showing a flow of game processing in the present embodiment. This process is realized by the game calculation unit 210 executing the game program 510.

  According to the figure, first, the game calculation unit 210 sets the virtual trackball screen display region 34 and the game screen display region 32 in the image display unit 30 based on the display screen setting data 532 and sets the set virtual track. An area of the touch panel 3 corresponding to the ball screen display area 34 is set as an input area (step A11).

  Next, the game calculation unit 210 constructs a game stage in which the passage PS, the start point, the goal point, and the like are arranged in the game space based on the stage data 534 (step A13). Then, the operation target character control unit 218 places the operation target character CA in a predetermined initial posture at a start point provided on the passage PS in the constructed game stage. Then, the game screen display control unit 224 arranges the virtual camera CM1 at a position based on the position (initial position) of the operation target character CA in a predetermined gaze direction, and generates an image of the game space viewed from the virtual camera CM1. The data is generated by the unit 230 and displayed as the game screen GW in the game screen display area 32 of the image display unit 30 (step A15).

  Also, the virtual trackball control unit 222 places the virtual trackball TB in an initial posture at a predetermined placement position in the virtual trackball space. Next, the virtual trackball screen display control unit 226 places the virtual camera CM2 in a predetermined line-of-sight direction above the virtual trackball TB, and displays an image of the virtual trackball space viewed from the virtual camera CM2 on the image generation unit 230. It is generated and displayed as a virtual trackball screen TW in the virtual trackball screen display area 34 of the image display unit 30 (step A17).

Thereafter, the process of loop A is executed for each frame (step A19).
In the loop A, first, a movement vector calculation process by the sliding touch operation detection unit 214 and the movement vector calculation unit 216 is executed.

  FIG. 28 is a flowchart showing the flow of the movement vector calculation process. According to the figure, in the movement vector calculation process, first, the movement vector calculation unit 216 determines the terrain condition and the environmental condition at the current position of the operation target character CA, and calculates the external force vector F based on the determined condition. (Step B11).

  Further, the sliding touch operation detection unit 214 captures the touch position P detected by the touch panel 3 (step B13), and determines whether or not the sliding touch operation is detected based on the captured touch position P. That is, if the touch position P is captured continuously with the current frame and the previous frame, it is determined that a sliding touch operation has been detected, and otherwise, it is determined that it has not been detected.

If the sliding touch operation has been detected (step B15: YES), the sliding touch operation detection section 214, the touch position P ₀ captured in the previous frame as a start point, and end point of the touch position P taken in the current frame The input vector a to be calculated is calculated (step B17).

Then, the movement vector calculation unit 216 inputs an input according to the equation (2) based on the calculated input vector a, the input action determination function f set for the operation target character CA and the movement vector V ₀ in the previous frame. An action vector A is calculated (step B19). Next, based on the calculated input action vector A, the previously calculated external force vector F, and the movement vector V ₀ in the previous frame, the movement vector V in the current frame is calculated according to Equation (1). That is, the movement vector V ₀ , the input action vector A, and the external force vector F are combined to calculate the movement vector V (step B 21).

On the other hand, if the sliding touch operation is not detected in step B15 (step B15: NO), the movement vector calculation unit 216 uses the equation (2) based on the previously calculated external force vector F and the movement vector V in the previous frame. In 1), the movement vector V is calculated with A = 0. That is, the movement vector V ₀ and the external force vector F are combined to calculate the movement vector V (step B23).
When the above process is performed, the movement vector calculation process ends.

  When the movement vector calculation process ends, a game screen display process is then executed by the operation target character control unit 218 and the game screen display control unit 224 (step A23).

FIG. 29 is a flowchart showing the flow of the game screen display process. According to the figure, in the game screen display process, first, the operation target character control unit 218 performs the movement distance L _c of the operation target character CA from the current frame to the next frame based on the calculated movement vector V. Is calculated according to equation (3), and the rotation angle θ _c is calculated according to equation (4) (step C11).

Next, the operation target character control unit 218 moves the position moved by the movement distance L _c calculated from the current position of the operation target character CA toward the direction (direction) of the movement vector V in the next frame. The position is determined (step C13). Further, the direction of the operation target character CA is set to a direction that coincides with the direction (direction) of the movement vector V, and the posture rotated by the rotation angle θ _c calculated from the current posture is determined as the posture in the next frame (step C15). . Then, the operation target character CA is rearranged in the game space at the determined position and posture (step C17).

Then, the game screen display control unit 224 rearranges the virtual camera CM1 based on the position of the rearranged operation target character CA (step C19). Then, the image generation unit 230 generates an image of the game space viewed from the virtual camera CM1, and displays it as the game screen GW in the game screen display area 32 of the image display unit 30 (step C21).
When the above processing is performed, the game screen display processing ends.

  When the game screen display process ends, the virtual trackball screen display process is then executed by the virtual trackball control unit 222 and the virtual trackball screen display control unit 226 (step A25).

FIG. 30 is a flowchart showing the flow of the virtual trackball screen display process. According to the figure, in the virtual trackball screen display process, first, the virtual trackball control unit 222 performs the rotation angle of the virtual trackball TB from the current frame to the next frame based on the calculated movement vector V. θ _t is calculated according to equation (5) (step D11).

Then, the direction that matches the orientation (z _t-axis positive direction) of the virtual track ball TB in the direction of the movement vector V, and posture obtained by rotating the current attitude by the rotation angle theta _t virtual trackball TB in the next frame position (Step D13). Then, the virtual trackball TB is rearranged in the virtual trackball space with the determined posture (step D15).

Then, the virtual trackball screen display control unit 226 causes the image generation unit 230 to generate an image of the virtual trackball space viewed from the virtual camera CM1 (image of the virtual trackball TB) (step D17), and the movement vector V A corresponding image of the moving display body EX is generated, and the generated image is combined with the image of the virtual trackball TB (step D19). Then, the combined image is displayed as a virtual trackball screen TW in the virtual trackball screen display area 34 of the image display unit 30 (step D21).
When the above processing is performed, the virtual trackball screen TW ends.

  When the virtual trackball screen display process ends, the game calculation unit 210 determines whether to end the game (step A27). Specifically, if the position of the operation target character CA that has been rearranged is the goal point, it is determined as “game success”, and if it is out of the path PS, it is determined as “game failure” Both ends the game. In other cases, that is, if the position of the operation target character CA is on the passage PS that is not the goal point, the game is not finished. Here, a time condition may be added as a condition for determining the end of the game. That is, it is determined whether or not the elapsed time from the game start time has exceeded a predetermined time limit.

When the game calculation unit 210 determines that the game is over (step A27: YES), the processing of the loop A is finished. When the loop A ends, the game calculation unit 210 performs end effect processing according to the determined game result. That is, if it is determined that “game is successful” and the game is ended, a success effect process is performed. On the other hand, if it is determined that “game is failed” and the game is ended, a failure effect process is performed (step A29).
When the above process ends, the game process ends.

[Action / Effect]
As described above, according to the present embodiment, the display 2 of the game apparatus 1 displays the game screen GW displaying an image of the game space at the top and the virtual track displaying the image of the virtual trackball TB at the bottom. A ball screen TW is displayed. When the sliding touch operation is performed on the virtual trackball screen TW, the direction and the moving direction of the operation target character CA on the game screen GW change in a direction along the operation direction (sliding operation direction) of the sliding touch operation. In addition, the moving speed changes to a speed corresponding to the operation amount (sliding operation amount) of the sliding touch operation. In addition, the rotation direction of the virtual trackball TB on the virtual trackball screen TW and the direction (direction) of the moving display body EX change in a direction substantially coincident with the movement direction of the operation target character CA on the game screen GW, and the virtual trackball The rotational speed of TB and the length of the moving display body EX are changed to a speed and length corresponding to the moving speed of the operation target character CA.

  Accordingly, a new input operation using a sliding touch operation such as controlling the movement of the operation target character CA in the game space based on the sliding operation direction and the sliding operation amount can be realized. In this case, the rotation direction of the virtual trackball TB on the virtual trackball screen TW and the direction (direction) of the moving display body EX are controlled so as to substantially coincide with the movement direction of the operation target character CA on the game screen GW. The player can easily perform an appropriate sliding touch operation while referring to the rotation direction and rotation speed of the virtual trackball TB.

[Modification]
The application of the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.

(A) Changing the display form of the virtual trackball TB For example, the form, size, and color of the virtual trackball TB may be changed according to the moving speed and moving direction of the operation target character CA.

  Specifically, for example, the shape of the virtual trackball TB that is a sphere is changed to an elliptical shape when the movement speed of the operation target character CA exceeds a predetermined speed. Further, the size of the virtual trackball TB may be linearly changed, for example, increasing (or decreasing) as the moving speed of the operation target character CA increases (or decreases).

  Further, the moving speed variable range of the operation target character CA is divided into a plurality of speed ranges, and a predetermined size or display color is associated with each speed range. Then, the virtual trackball TB may be changed to a corresponding size or color according to which speed range the current moving speed of the operation target character CA belongs to.

  Furthermore, when the moving speed satisfies a predetermined speed condition, the virtual trackball TB may be changed to a predetermined shape, size, or display color. In this case, as a predetermined speed condition, for example, an appropriate movement speed range of the operation target character CA in the game space is set in advance, and if the movement speed of the operation target character CA is within this movement speed range, an appropriate movement is performed. The display color indicating the speed is changed, or on the contrary, an inappropriate moving speed range such as too slow or too fast is set as a predetermined speed condition, and the moving speed of the operation target character CA is this movement. If it is within the speed range, it can be changed to a display color indicating a warning.

(B) Changing the Display Form of the Moving Display EX The display form of the moving display EX may be changed according to the moving speed of the operation target character CA. In the embodiment described above, the length of the moving display body EX is changed according to the moving speed of the operation target character CA. However, the size and display color are changed according to the moving speed of the operation target character CA. It is also good to do. Specifically, for example, as the moving speed of the operation target character CA becomes larger (faster), the moving display body EX is enlarged so that the increase in the moving speed can be easily grasped visually. Further, the moving speed variable range of the operation target character CA is divided into a plurality of speed ranges, and a predetermined size or display color is associated with each speed range. Then, the moving display body EX may be changed to a corresponding size or color according to which speed range the current moving speed of the operation target character CA belongs to.

(C) Number of Displays In the above-described embodiment, the game apparatus 1 includes one display 2 as the image display unit 30, and the game screen display area 32 that displays the game screen GW and the virtual track on the display 2. The virtual trackball screen display area 34 for displaying the ball screen TW is formed, but two displays may be provided. In this case, at least one of the displays is integrally formed with the touch panel as the second display unit. Then, the virtual trackball screen TW is displayed on one display on which the touch panel is integrally formed, and the game screen GW is displayed using the other display as the first display unit.

(D) Game screen GW
In the above-described embodiment, the viewing direction of the virtual camera CM1 in the game space is fixed, and the movement direction of the operation target character CA on the game screen GW corresponds to the change in the movement direction of the operation target character CA in the game space. However, the moving direction of the operation target character CA on the game screen GW is always a constant direction by setting the line-of-sight direction of the virtual camera CM1 to a direction corresponding to the line-of-sight direction of the operation target character CA. You may make it become.

  At this time, if the virtual camera CM1 is arranged at substantially the same position as the operation target character CA with the line-of-sight direction along the direction (that is, the movement direction) of the operation target character CA, the game screen GW has a so-called first-person viewpoint. If the operation target character CA is an airplane, an image (for example, an image of a cockpit view; an image called a cockpit view) is displayed, and the movement direction of the operation target character CA on the game screen GW is upward with respect to the game screen GW. It becomes constant. Further, when the virtual camera CM1 is made to follow from the rear in the moving direction of the operation target character CA and is arranged so that the line-of-sight direction is a direction slightly looking down on the operation target character CA, the game screen GW can be viewed from above the game space diagonally upward. The bird's-eye view image (an image called a bird view) is displayed, and the movement direction of the operation target character CA on the game screen GW is constant upward with respect to the game screen GW. Further, the virtual camera CM1 has an upward direction (upper side of the virtual camera CM1 itself; upper part of the virtual camera CM1) as a direction along the moving direction of the operation target character CA (more specifically, the tilt angle of the virtual camera CM1). When the line-of-sight direction is arranged vertically downward, the game screen GW becomes an image obtained by bird's-eye view of the game space from directly above the sky, and the operation target character CA on the game screen GW is displayed. The moving direction is constant upward with respect to the game screen GW.

Further, in this case, the virtual camera CM2 in the virtual trackball space is rotated (tilted) around the line-of-sight direction according to the change in the line-of-sight direction of the virtual camera CM1 in the game space (that is, conversion of the movement direction of the operation target character CA). By doing so, the rotation direction of the virtual trackball TB on the virtual trackball screen TW may always be constant in the direction along the moving direction of the operation target character CA on the game screen GW (that is, upward). Specifically, the virtual camera CM2 is rotated so that the coordinate directions of the spatial coordinate system on each screen of the game screen GW and the virtual trackball screen TW coincide. More specifically, in the above-described embodiment, in FIGS. 8 and 9, the upward direction of the virtual camera CM2 (upper side of the virtual camera CM2 itself; upper part of the virtual camera CM2) is fixed as the positive direction of the Z _T axis (tilt let not), which, as the axis about an axis parallel to the street and Y _T axis the center of the virtual camera CM2, causes rotation as the direction and z _t-axis positive direction over the virtual camera CM2 match (tilt).

(E) Virtual trackball screen TB
In the embodiment described above, the virtual trackball screen TW and the moving display body EX are displayed on the virtual trackball screen TW. However, only one of them may be displayed.

(F) Operation target character CA
In the above-described embodiment, the operation target character CA is moved while rotating in the game space, but may not be rotated. Although the operation target character CA is a sphere, it may be a model (object) in the shape of a person, a car, an airplane, or the like.

(G) Electronic Device to be Applied Further, in the above-described embodiment, the case where the present invention is applied to the portable game device 1 which is a kind of electronic device has been described. However, the present invention is applied to other electronic devices such as a PDA, for example. You may do it.

  Further, as shown in FIG. 31, the portable game device 1 may be connected to a main device 1100 of a home game device and used as a game controller. According to the figure, the home game device includes a main body device 1100 and a portable game device 1 that is a game controller connected to the main body device 1100, and the main body device 1100 includes a speaker 1202. The display 1200 provided is connected by a cable K capable of transmitting an image signal and a sound signal.

  The main device 1100 includes a control unit in which, for example, a CPU and an IC memory are mounted, and a reading / writing device for an information storage medium such as a CD-ROM 1104, an IC card 1106, and a memory card 1108. Then, various game processes are executed based on the game information read from the CD-ROM 1104 and the like and the operation signal from the game apparatus 1, and the image signal (game image signal) of the game screen GW and the virtual trackball screen TW are displayed. An image signal (virtual trackball image signal) and a sound signal of a game sound are generated. The generated game image signal and sound signal are output to the display 1200, the game screen GW is displayed on the display 1200, the game sound is output from the speaker 1202, and the virtual trackball image signal is output to the game apparatus 1. The virtual trackball screen TW is displayed on the display 2. While watching the game screen GW displayed on the display 1200, the player enjoys the game by inputting a game operation by performing a sliding touch operation on the display 2 of the game apparatus 1 or the like.
