Description

  The present invention relates to a program or the like for causing a computer to display and control a player character placed in a game space to execute a predetermined game.

The arcade game apparatus has a casing dedicated to the game to be executed, and is popular in that it allows the user to enjoy a sensation-type game as compared with the home game apparatus. In view of this, devices that allow sensuous input have been developed even for input devices of home game devices. As one of such sensible input devices, a device using the weight of a player as an input element is known. For example, an apparatus (Patent Document 1) that measures the position of the center of gravity of a subject by using a center-of-gravity detection device with a built-in weight measurement circuit (Patent Document 1), or an input that detects movement of the center of gravity of a player as an input device of a game device This is an apparatus (Patent Document 2).

  The input devices of Patent Literature 1 and Patent Literature 2 detect the movement of the center of gravity of a player riding on the input device and use it for a game or the like. That is, the player makes a desired input by moving his / her body weight back and forth, right and left on the input device, and changing the position of the center of gravity of the body.

[Game system configuration]
FIG. 1A is a configuration diagram of a game system 1000 according to the present embodiment. According to FIG. 5A, the game system 1000 includes a main body device 1100, a video monitor 1200, and a board type controller 1300.

  The main unit 1100 includes a control unit 1110 on which, for example, a CPU, an image processing LSI, an IC memory, and the like are mounted, and information storage medium reading devices 1106 and 1108 such as an optical disk 1102 and a memory card 1104.

  The control unit 1110 includes various microprocessors such as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), and a DSP (Digital Signal Processor), and an electrical and electronic device such as an ASIC (Application Specific Integrated Circuit) and an IC memory. Each part of the system 1000 is controlled.

  In addition, the control unit 1110 includes a communication device 1112 that is wired or wirelessly connected to a communication line N such as the Internet, a LAN (Local Area Network), or a WAN (Wide Area Network), and realizes data communication with an external device. Prepare. Furthermore, the control unit 1110 includes a short-range wireless communication module 1114 and realizes data transmission / reception with the board type controller 1300 via the short-range wireless communication. As a short-range wireless format, for example, Bluetooth (registered trademark), UWB (ultra-wide band wireless), wireless LAN, or the like can be applied as appropriate.

  Then, the control unit 1110 executes various game calculations based on the game program and various setting data read from the optical disk 1102 and the memory card 1104, data received from the board type controller 1300, etc., and displays game images and sound. Generate. And the produced | generated game image and game sound are output to the video monitor 1200 (display monitor) connected with the signal cable. The video monitor 1200 includes a display 1202 that displays an image and a speaker 1204 that emits sound, and a player can play a game sound emitted from the speaker 1204 while viewing a game image displayed on the display 1202. You can play the game while listening.

  The board-type controller 1300 is formed in a substantially rectangular plate shape that is large enough to allow the player to stand on the upper surface, and the player operates by performing predetermined physical movements on the upper surface. Make input. Further, as shown in the plan view of FIG. 5B, the board type controller 1300 has a total of four pressure sensors 1302 in each of the four corners of the rectangle, and measures the load such as the weight of the player. It has the function of a section (weight scale). The board-type controller 1300 only needs to be able to calculate the position of the center of gravity of the player, and the number of pressure sensors 1300 and their arrangement positions are not limited thereto.

  The board-type controller 1300 includes a control unit 1310. The control unit 1310 performs short-distance wireless communication with various short-distance wireless communication modules 1114 of the main body device 1100, for example, various microchips such as a bus controller IC that controls data communication in a CPU and a local bus circuit, IC memory, and the like. A wireless communication device to be realized is mounted, and a measurement value by the pressure sensor 1302 is transmitted to the main body device via the short-range wireless communication. Note that the main apparatus 1100 and the board-type controller 1300 may be wired by a communication cable, and data may be transmitted / received via the communication cable.

  Note that the game system 1000 may further include a stick-type controller that the player holds and operates with one hand as another input device for inputting the instruction operation of the player. This stick type controller incorporates a control unit equipped with a CPU, an IC memory, etc., and a communication device for realizing wired / wireless communication with the main unit 1100, and a button for a player to operate with a finger. Has a switch. In this case, the player performs an operation input by performing a predetermined physical movement on the board type controller 1300, and also performs an operation input by a stick type controller held by the hand.

[Game Overview]
In the game system 1000, a snowboard game is executed. FIG. 2 is a diagram illustrating the game screen and the player's operation posture in the present embodiment. In the game of the present embodiment, a background space such as a tree is arranged on a terrain object such as the snow surface 2 in the three-dimensional virtual space, and a game space that is a slope is formed. Another character which is a player character (NPC) is arranged. Then, an image of the game space viewed from a virtual camera provided so as to follow the player character PC is displayed as a game screen. Therefore, as shown in the upper side of the figure, the rear view of the player character PC sliding on the snow surface 2 is displayed on the game screen.

  As shown in the lower side of the figure, the player PL rides sideways with respect to the display 1202 on the board-type controller 1300 that is arranged vertically with the longitudinal direction facing the display 1202, and faces the display 1202. Take posture. In the figure, the player PL is placed in a posture where the left foot of the player PL is on the front side. Then, on the board-type controller 1300, by moving the body weight (load) applied to the left and right feet in the manner of a snowboard, operation inputs such as acceleration, deceleration, left and right turn are performed, and the player character PC on the snow surface 2 To control the operation.

  Here, when a stick-type controller is further used as an input device, the operation of the stick-type controller, for example, an auxiliary instruction such as an instruction of an action for raising a fallen player character PC, a virtual camera, a display screen, or a BGM switching instruction. Operation input may be performed.

  Specifically, as one of the operations performed by the player PL, there are a center of gravity moving operation for performing acceleration, deceleration, and left and right turns. FIG. 3 is a diagram for explaining the gravity center moving operation. In the figure, the upper side shows the game screen, and the lower side shows the operation of the player PL. The center-of-gravity movement operation is an operation for instructing the player character PC to accelerate or decelerate and to turn left and right by tilting the player PL and moving the center of gravity (load).

  For example, as shown in the figure, when the player PL tilts his body to the right and moves the load to the toe side, the player character PC turns to the right. Conversely, when the player PL tilts his body to the left and moves the load to the heel side, the player character PC turns to the left. Further, when the player PL leans forward and moves the load to the front foot, the moving speed of the player character PC is reduced. Conversely, when the player PL tilts his / her body in the backward direction and moves the load to the rear foot, the moving speed of the player character PC is accelerated.

  When the player character PC is sliding on the snow surface 2 and the player PL performs a “jump instruction operation” as shown in FIG. 4, the player character PC in the game screen jumps. In other words, the jump instruction operation is an operation of extending the upper body upward (extending) as if jumping on the spot as shown in the lower side of the figure. However, both feet remain on the board type controller 1300. Then, as shown in the upper side of FIG.

  When the “landing instruction operation” shown in FIG. 5 is performed at the landing timing (or the timing immediately before landing) after the player character PC jumps by the jump instruction operation, the player character PC has landed on the snow surface 2. At that time, a predetermined “landing operation (landing action)” is performed. That is, the landing instruction operation is an operation in which the player PL steps down (pushes down), as shown on the lower side of the figure, contrary to the above-described jump instruction operation. Then, as shown in the upper side of the figure, the player character PC performs a special landing action (“gut pose” in the figure) such as successful landing and determining a pose. If the landing instruction operation is not performed, the player character PC performs a normal landing operation without performing a special landing operation.

[principle]
(A) Detection of Player Operation First, the principle of detection of player operation performed by the board type controller 1300 will be described. The player operation performed by the board type controller 1300 is detected based on the measured values of the four built-in pressure sensors 1302.

(A-1) Center-of-gravity movement operation The center-of-gravity movement operation is detected as the center-of-gravity position R of the player by the operation. FIG. 6 is a diagram for explaining calculation of the center of gravity position R of the player, and shows a plan view of the board type controller 1300. As shown in the figure, the center-of-gravity position R of the player is calculated from the measured values of the pressure sensors 1302 as a kind of load balance. In the present embodiment, as shown in FIG. 2, the board type controller 1300 is arranged with its longitudinal direction facing the display 1202. The center-of-gravity position R is expressed by a two-dimensional input coordinate system (Xc, Yc) in which the longitudinal direction of the board-type controller 1300 coincides with the Yc axis and the short direction coincides with the Xc axis. In addition, the origin O of the input coordinate system (Xc, Yc) coincides with a reference position O corresponding to the center of gravity position R in a state where all measured values of the four pressure sensors 1302 are equal.

(A-2) Jump instruction operation and landing instruction operation The jump instruction operation and the landing instruction operation are detected from a change in the measured value of the pressure sensor 1302. Incidentally, both the jump instruction operation and the landing instruction operation are operations in which the player moves rapidly, and the measurement value of the pressure sensor 1302 changes instantaneously. Moreover, the change of the measured value is almost the same regardless of which operation is performed. That is, it is not possible to distinguish whether the player has performed a jump instruction operation or a landing instruction operation only by changing the measurement value. Therefore, in the present embodiment, it is determined which of the jump instruction operation and the landing instruction operation has been performed according to the situation of the player character PC. That is, it is determined that the jump instruction operation has been performed while the player character PC is sliding, and it is determined that the landing instruction operation has been performed during the jump. “Sliding” means a state in which the player character PC is positioned on the sliding surface 2 and includes a state in which the player character PC is stopped (a state in which the moving speed is zero).

  FIG. 7 is a diagram illustrating an example of a change in the measurement value of the pressure sensor 1302 when the player performs a jump instruction operation. In addition, when the landing instruction operation is performed, the measurement value changes in substantially the same manner. As shown in the figure, when the player performs a jump instruction operation, the measured value changes instantaneously and a pulse is generated. Specifically, in a short time, pulses in both directions of an increase direction pulse (increase pulse) and a decrease direction pulse (decrease pulse) alternately and instantaneously occur. Such instantaneous generation of pulses in both directions is a phenomenon peculiar to an operation of extending (corresponding to a jump instruction operation) or an operation of depressing (corresponding to a landing instruction operation). If the player PL jumps on the board type controller 1300, a period in which the measured value is zero occurs and a pulse is generated only in one direction. The same applies when the player PL is dropped from the board type controller 1300.

  There are the following two patterns of pulse generation depending on the operation of the player. That is, as shown in FIG. 6A, a pattern in which the measured value increases instantaneously and then decreases, that is, a pattern in which a decrease pulse occurs after an increase pulse is generated, and FIG. Thus, there are two patterns: a pattern in which the measured value decreases instantaneously and then increases, that is, a pattern in which an increasing pulse is generated after a decreasing pulse is generated. Specifically, when a person tries to grow, the pulse generation pattern differs depending on whether the person who has stepped in for a moment to gain momentum and then grows, and the person who grows as it is. The same applies when stepping on. Therefore, in the present embodiment, when the detection condition is “when both the increasing pulse and the decreasing pulse are detected within a predetermined time”, the jump instruction operation or the landing instruction operation (hereinafter referred to as “jump”). / Landing instruction operation) is detected.

The detection of the pulse is performed by setting a threshold value THa based on the stationary weight (static load) W of the player and detecting that the measured value has reached the threshold value THa. That is, as the pulse detection threshold value THa, an increase amount threshold value THa ₁ larger than the player's stationary weight W by the increase / decrease reference amount ΔWa and a decrease amount threshold value THa ₋₁ smaller by the increase / decrease reference amount ΔWa are set. Then, an increase pulse is detected when the measured value is greater than or equal to the increase amount threshold THa _1, and a decrease pulse is detected when the measured value is equal to or less than the decrease amount threshold THa- ₁ . The increase / decrease reference amount ΔWa is set so as to increase as the stationary weight W increases (heavy) based on the stationary weight W of the player. Specifically, it is determined as a value of a predetermined ratio (for example, 20%) of the stationary weight W.

Further, in order to determine that a pulse in both directions has been detected within a predetermined time, the time point when the measured value reaches _{one of the} pulse detection thresholds THa ₁ and THa ₋₁ (the detection time point of the first pulse) A next pulse detection period T1 as a start time is determined. When the measured value reaches the other of the pulse detection thresholds THa ₁ and THa ₋₁ (detection of the second pulse) within this next pulse detection period T ₁ , the detection condition (jump / landing operation) is determined. Assuming that (landing instruction detection condition) is satisfied, a jump / landing instruction operation is detected.

For example, in FIG. (A), at time t1 the measurement value reaches the increased amount threshold THa _1, the generation of increased pulse (first pulse) is detected. Then, the next pulse detection period T1 starting from this time t1 is determined, and when the measured value reaches the decrease amount threshold THa _-1 at time t2 in the next pulse detection period T1, a decrease pulse (second Pulse) is detected, and a jump / landing instruction operation is detected at this point. Further, in FIG. 7B, at time t4 when the measured value reaches the decrease amount threshold THa- ₁ , the occurrence of a decrease pulse (first pulse) is detected, and the next pulse starting at this time t4. A detection period T1 is determined. When the measured value at time t5 of the next pulse detection period T1 reaches the increment threshold THa _1, both are detecting the occurrence of increased pulse (second pulse), jump / landing instruction operation at this point Is detected.

(B) Character Control Next, control of the player character PC based on the detected player operation will be described. The player character PC is controlled by correcting the current velocity vector V0 based on the player operation detected as being performed by the board type controller 1300 every predetermined control cycle (for example, 1/60 second), This is performed according to the corrected velocity vector V1.

(B-1) During sliding First, during the sliding of the player character PC, the next velocity vector V1 is calculated based on the center of gravity position R of the player by the center of gravity moving operation.

  FIG. 8 is a diagram for explaining the calculation of the velocity vector V1 during sliding. The figure (a) is the figure which looked at the sliding surface (snow surface) 2 from upper direction, and the figure (b) is a vertical sectional view of the sliding surface 2 along the present velocity vector V0. As shown in the figure, the forces acting on the player character PC at the current position P0 are the current velocity vector V0, gravity G, and action gravity vector R1. The velocity vector V0 is determined in the direction along the sliding surface 2. Gravity G acts vertically downward. The action centroid vector R1 is a vector expressing the action of the centroid movement operation by the player, and is determined based on the centroid position R. The action centroid vector R1 acts in a direction along the sliding surface 2. The sum of the current velocity vector V0, the acting gravity center vector R1 and the slope component of the gravity G is set as the next velocity vector V1. That is, the direction of the next velocity vector V1 is the direction along the sliding surface 2, and the player character PC moves (slides) the sliding surface 2 according to the velocity vector V.

  FIG. 9 is a diagram for explaining the determination of the action centroid vector R1 based on the centroid position R. As shown in FIG. 6A, in the input coordinate system (Xc, Yc) in the board type controller 1300, the center of gravity position R and a position symmetrical with respect to the Xc axis as the target axis are defined as the center of gravity position R1. Next, each of the gravity center positions R and R1 is converted into a position in the game space by coordinate conversion as shown in FIG. At this time, the Xc-Yc plane that is the input coordinate system is made to coincide with the sliding surface 2 in the game space. Further, the origin O of the input coordinate system (Xc, Yc) is matched with the current position P0 of the player character PC, and the positive direction of the Yc axis is matched with the direction of the player character PC.

  Then, as shown in FIG. 6B, in the game space, a vector from the player's current position P0 to the centroid position R is set as an input centroid vector R0, and a vector from the current position P0 to the centroid position R1 is set as an action centroid vector R1. And

  That is, the acting gravity center vector R1 changes according to the gravity center position R, and as a result, the direction and magnitude of the next velocity vector V1 with respect to the current velocity vector V0 changes. As a result, the player character PC slides while changing its moving direction (turn) or accelerating or decelerating.

(B-2) Jump instruction operation When a jump instruction operation is detected during a run, jump control for causing the player character PC to perform a jump operation is performed.

  FIG. 10 is a diagram for explaining the calculation of the velocity vector V1 when a jump instruction operation is performed. FIG. 4A is a view of the sliding surface 2 as viewed from above, and FIG. 4B is a vertical sectional view of the sliding surface 2 along the current velocity vector V0. As shown in the figure, the forces acting on the player character PC when the jump instruction operation is detected are gravity G, action gravity vector R2 and jump vector H. The current velocity vector V0 acts in a direction along the sliding surface 2. Gravity G acts vertically downward.

  The action center-of-gravity vector R2 is a vector representing the action of the center-of-gravity position R of the player when the jump instruction operation is detected, and is determined based on the center-of-gravity position R when the jump instruction operation is detected. This action centroid vector R2 acts in a direction along the sliding surface 2. The jump vector H is a vector that represents the action of the jump instruction operation by the player, and is determined by adjustment based on the measured value of the pressure sensor 1302 when the jump instruction operation is detected. This jump vector H acts vertically upward with respect to the sliding surface 2.

  The sum of the velocity vector V0, the acting gravity center vector R2, the slope component of the gravity G, and the jump vector H is set as the next velocity vector V1. That is, the next velocity vector V1 is an upward vector with respect to the sliding surface 2. For this reason, the player character PC jumps upward away from the sliding surface 2.

  FIG. 11 is a diagram for explaining the calculation of the acting gravity center vector R2. The center of gravity position R defined by the input coordinate system (Xc, Yc) in the board type controller 1300 shown in FIG. 6A is converted into a position in the game space by a predetermined coordinate transformation as shown in FIG. Convert to At this time, the Xc-Yc plane, which is the input coordinate system, is made to coincide with the sliding surface 2 in the game space, as in the case of the sliding shown in FIG. Further, the origin O of the input coordinate system (Xc, Yc) is matched with the current position P0 of the player character PC, and the positive direction of the Yc axis is matched with the direction of the player character PC. Then, as shown in FIG. 11B, a vector from the current position P0 of the player character PC toward the center of gravity R is defined as an action center of gravity vector R2.

  In this way, the acting gravity center vector R2 changes according to the gravity center position R, and as a result, the direction and magnitude of the velocity vector V1 with respect to the current velocity vector V0 changes. As a result, the jump direction of the player character PC changes to the left or right with respect to the current movement direction, or the flight distance changes.

  The direction of the jump vector H is vertically upward with respect to the sliding surface 2. The magnitude of the jump vector H is determined according to the amount of change in the measurement value of the pressure sensor 1302 caused by the jump instruction operation. The larger the amount of change, the larger the magnitude of the jump vector H is determined. In the present embodiment, the peak value (magnitude) of the measured value pulse is used as the amount of change in the measured value due to the jump instruction operation.

  FIG. 12 is a diagram illustrating an example of a measurement value of the pressure sensor 1302 when a jump instruction operation is detected. As shown in the figure, a plurality of peak detection thresholds THb are defined in order to detect the peak value of the pulse, and among these, the peak detection threshold THb that has reached the measured value is taken as the peak value of the pulse. The reference increase / decrease amount ΔWb that is the interval between the threshold values THb is determined based on the static weight W, for example, as a value of a predetermined ratio (for example, 5%) of the static weight W. The peak value of each of the two pulses having the larger absolute value (that is, the threshold value THb having the largest absolute value among the peak detection threshold values THb that have reached the measured value) is the measured value obtained by the jump instruction operation. The amount of change.

In the figure, as thresholds THb for peak detection, thresholds THb _{1 to} THb _{3 that} are larger than the increase amount threshold THa ₁ for detecting the increase pulse, and thresholds THb ₋₁ to THb _{−1 that are} smaller than the decrease amount threshold THa ₋₁ for detecting the decrease pulse. THb- ₃ is set. First, at time t11, the measured value increases reached one pulse detection threshold THa ₁ pulse (first pulse) is detected. Further, the measured values reach the peak detection thresholds THb ₁ and THb ₂ . Accordingly, the peak value of the increase pulses is the peak detection threshold THb _2. Next, at time t12, the measured value reaches the other pulse detection threshold THa- _1, and a decrease pulse (second pulse) is detected. Further, the measured value reaches the peak detection thresholds THb _{−1 to} THb ₋₃ . Accordingly, the peak value of the decrease pulse is the peak detection threshold THb- ₃ . Then, the threshold value THb- _3, which is the peak value with the larger absolute value of the peak values of the increase pulse and the decrease pulse, is set as the change amount of the measurement value by the jump instruction operation. When the pulse does not reach the peak detection threshold THb, the corresponding pulse detection threshold THa is set as the peak value of the pulse.

  As described above, the magnitude of the jump vector H is adjusted and changed in accordance with the amount of change in the measured value by the jump instruction operation. As a result, the magnitude of the next speed vector V1 with respect to the current speed vector V0 and the sliding surface 2 are changed. The angle (elevation angle) changes. The jump height of the player character PC increases as the magnitude of the jump vector H increases or as the angle of the speed vector V1 with respect to the sliding surface 2 increases.

  When the next velocity vector V1 is calculated in this way, as shown in FIG. 13, the movement trajectory in the air of the jumped player character PC is calculated by a known physical calculation, based on this velocity vector V1. . That is, the position P at each time t in the control cycle time Δt interval is calculated, and the estimated landing time tn and the estimated arrival position Pn for landing (arriving) on the sliding surface 2 when moving along the moving track are calculated. The Next, a landing operation instruction reception period T3 including the estimated arrival time tn is set. The player character PC moves (flys) along this movement trajectory, thereby realizing a jump.

  When a landing instruction operation is detected within the landing operation reception period T3, the player character PC performs a special landing action such as “Guts Pause” shown in FIG. On the other hand, when the landing instruction operation is not detected within the landing operation reception period T3, the player character PC performs a normal landing action when landing on the sliding surface 2.

Here, after the jump instruction operation is detected, even if a change in the measurement value of the pressure sensor 1302 reaching the pulse detection thresholds THa ₁ and THa ₋₁ is detected in the period before the landing operation reception period T3. Neither jump instruction operation nor landing instruction operation is considered to have been performed. Accordingly, it is possible to prevent malfunctions such that jump instruction operations are continuously detected in a short time and a further jump action is performed on the player character PC during the jump.

[Function configuration]
FIG. 14 is a functional configuration diagram of the game system 1000. According to the figure, the game system 1000 functionally includes an operation input unit 100, a measurement unit 200, a processing unit 300, a communication unit 400, an image display unit 500, and a sound output unit 600. Configured.

  The operation input unit 100 receives an operation input from the player and outputs an operation signal corresponding to the operation to the processing unit 300. By the operation input unit 100, an instruction to start / end a game, selection of a character or course, and the like are input by the player. This function is realized by an input device such as a push button, lever, touch pad, dial, keyboard, mouse or the like. In FIG. 1, a stick-type controller (not shown) connected to the main unit 1100 and operated by the player PL by hand is applicable.

  The measuring unit 200 measures a load such as the weight of the player and outputs the measured value to the processing unit 300. In FIG. 1, the board type controller 1300 corresponds to this, and has a plurality of pressure sensors (for example, four pressure sensors 1302 in FIG. 1B) for measuring body weight (load).

  The processing unit 300 performs various arithmetic processes such as overall control of the game system 1000, game progress, and image generation based on programs and data read from the storage unit 700, operation signals input from the operation input unit 100, and the like. This function is realized by, for example, a microprocessor such as a CPU or GPU, an ASIC (Application Specific Integrated Circuit), an IC memory, or the like. In FIG. 1, the control unit 1110 corresponds to this. The processing unit 300 includes a game calculation unit 310, an image generation unit 350, and a sound generation unit 360.

  The game calculation unit 310 executes processing related to the progress of the game. For example, a process for forming a game space that is a slope by placing objects such as a snow surface (sliding surface) 2 and trees in a three-dimensional virtual space, a process for placing a player character PC in the game space, and a character movement And various arithmetic processes such as a control process such as an attack, a hit determination process between objects, a physics calculation process, and a game result calculation process. In the present embodiment, the game calculation unit 310 includes an operation detection unit 312 and a player character control unit 314.

  The operation detection unit 312 detects an operation (player operation) performed by the player based on the measurement value input from the measurement unit 200. Specifically, as the center-of-gravity movement operation, the center-of-gravity position R of the player is calculated from the measurement value of each pressure sensor 1302 input from the measurement unit 200. The detected gravity center position R is stored in the gravity center position data 733.

  In addition, the operation detection unit 312 detects a jump / landing instruction operation from the change in the measurement value from the measurement unit 200. Here, the measurement value to be determined for detection of the jump / landing instruction operation is the sum of the measurement values of each pressure sensor 1302, but may be an average value.

  That is, as shown in FIG. 7, the increase / decrease reference amount ΔWa of the measurement value is calculated based on the stationary weight W of the player, and the threshold value THa for pulse detection is set. In addition, as shown in FIG. 12, based on the static weight W, an increase / decrease reference amount ΔWb of the measurement value is calculated, and a threshold value THb for peak detection is set. The set threshold values THa and THb are stored in the threshold data 731.

  FIG. 15 shows an example of the data configuration of the threshold data 731. According to the figure, the threshold data 731 includes the stationary weight (W) 731a of the player character PC, reference increase / decrease amounts (ΔWa, ΔWb) 731b, 731c, pulse detection threshold (THa) 731d, and peak detection. Threshold value (THb) 731e is stored.

  Then, as illustrated in FIG. 12, the operation detection unit 312 determines whether the measured value has reached the pulse detection threshold THa and the peak detection threshold THb. Here, the determination result as to whether the measured value has reached each of the threshold values THa and THb is stored in the arrival threshold value determination data 732.

  FIG. 16 shows an example of the data configuration of the arrival threshold value determination data 732. According to the figure, the arrival threshold value determination data 732 stores a determination result 732b indicating whether or not the measured value has been reached for each threshold value 732a of the pulse detection threshold value THa and the peak detection threshold value THb.

  When the measured value reaches one pulse detection threshold value THa, the operation detection unit 312 detects the first pulse, and sets the next pulse detection period T1 starting from this point. Next, when the measured value reaches the other pulse detection threshold THa within the next pulse detection period T1, it is determined that the second pulse is detected, and it is determined that the jump / landing instruction detection condition is satisfied. At this time, if the player character PC is sliding, it is determined that the operation performed is a jump instruction operation, and if the player character PC is jumping, it is determined that the operation performed is a landing instruction operation.

  If it is determined that a jump instruction operation has been performed, the peak value of the pulse is detected as the amount of change in the measured value resulting from this jump instruction operation. That is, as shown in FIG. 12, in the next pulse determination period T1, the threshold value TH having the largest absolute value among the threshold values THa and THb that have reached the measured value is determined as the amount of change in the measured value by the detected jump instruction operation. To do.

  The player character control unit 314 controls the player character PC in accordance with the player operation detected by the operation detection unit 312. Here, data on the player character PC is stored in the player character data 722. The player character data 722 includes data such as model data and motion data (including special landing motion) of the player character PC, position P, direction, velocity vector V, and the like.

  Specifically, while the player character PC is sliding, as shown in FIG. 9, the action centroid vector R1 is determined based on the centroid position R of the player detected as the centroid moving operation. Next, as shown in FIG. 8, the sum vector of the current velocity vector V0, the slope direction component of gravity G and the acting gravity center vector R1 is calculated and set as the next velocity vector V1. Then, the next position P1 of the player character PC is calculated in accordance with the calculated velocity vector V1, and movement control for moving toward the calculated position P1 is performed. At the same time, motion control is performed to cause the player character PC to perform a motion corresponding to the change in the position P.

  Further, if a jump instruction operation is detected during a run, as shown in FIG. 11, an action gravity center vector R2 is determined based on the center of gravity position R when the jump instruction operation is detected.

  Further, the magnitude of the jump vector H is determined with reference to the jump vector setting table 723 based on the detected change amount of the jump instruction operation. FIG. 17 shows an example of the data configuration of the jump vector setting table 723. According to the figure, the jump vector setting table 723 stores the magnitude 723b of the jump vector H in association with each threshold value 723a of the pulse detection threshold value THa and the peak detection threshold value THb. The operation detection unit 312 determines the magnitude corresponding to the threshold value TH detected as the amount of change in the measurement value according to the jump operation instruction as the magnitude of the jump vector H.

  Next, as shown in FIG. 10, the sum vector of the current velocity vector V0, the slope direction component of gravity G, the acting gravity center vector R2, and the jump vector H is calculated and set as the next velocity vector V1.

  Subsequently, a movement trajectory according to the calculated velocity vector V1 is calculated. In addition, when moving along this movement track, the planned landing time tn and the planned landing position Pn for landing on the running surface 2 are calculated, and a landing operation reception period T3 including the planned landing time tn is set. The movement trajectory data calculated here is stored in the movement data 734 when jumping. Then, the player character PC is moved (jumped) along the calculated movement trajectory. Thereafter, if a landing instruction operation is detected within the set landing operation reception period T3, a special landing action is performed on the player character PC when landing on the sliding surface 2, and if a landing instruction operation is not detected, Perform normal landing movement.

  Returning to FIG. 14, the image generation unit 350 includes a processor such as a GPU (Graphics Processing Unit) and a digital signal processor (DSP), a program such as a video signal IC and a video codec, a drawing frame IC memory such as a frame buffer, and the like. Realized. The image generation unit 350 generates one game image at a predetermined control cycle time (for example, 1/60 second) based on the processing result of the game calculation unit 310, and displays an image signal of the generated game image as an image display To the unit 500.

  Based on the image signal from the image generation unit 350, the image display unit 500 displays the game screen while redrawing an image of one frame every predetermined control cycle time (for example, 1/60 seconds). This function is realized by a display device such as a CRT, LCD, ELD, or PDP. In FIG. 1, the display 1202 corresponds to this.

  The sound generation unit 360 is realized by a processor such as a digital signal processor (DSP) or a voice synthesis IC, or an audio codec capable of playing back an audio file, for example. Based on the processing result of the game calculation unit 310, sound effects and BGM, Sound signals of various operation sounds are generated and output to the sound output unit 600.

  The sound output unit 600 outputs game sounds such as BGM and sound effects based on the sound signal input from the sound generation unit 360. This function is realized by an audio output device such as a speaker. In FIG. 1, the speaker 1204 corresponds to this.

  The communication unit 400 is connected to the communication line N to realize communication. This function is realized by, for example, a wireless communication device, a modem, a TA (terminal adapter), a wired communication cable jack, a control circuit, or the like. In FIG. 1, the communication device 1112 corresponds to this.

  The storage unit 700 stores a system program for realizing various functions for causing the processing unit 300 to control the game system 1000 in an integrated manner, a game program necessary for executing the game, various data, and the like. Further, it is used as a work area of the processing unit 300, and temporarily stores calculation results executed by the processing unit 300 according to various programs, input data input from the operation input unit 100 and the measurement unit 200, and the like. This function is realized by, for example, an IC memory such as a RAM and a ROM, a magnetic disk such as a hard disk, and an optical disk such as a CD-ROM and DVD. In FIG. 1, the optical disk 1102, the memory card 1104, the IC memory mounted on the control unit 1110, and the like correspond to this. In the present embodiment, a game program 710 is stored as a program in the storage unit 700, and course data 721, player character data 722, jump vector setting table 723, threshold data 731, and reach are stored as data. Threshold determination data 732, barycentric position data 733, and jump movement data 734 are stored.

[Process flow]
FIG. 18 is a flowchart for explaining the flow of the game process. According to the figure, the game calculation unit 310 first measures the stationary weight (static load) W of the player as an initial setting. In other words, the player stands on the board-type controller 1300 that is the measuring unit 200 and stands still by, for example, screen display or audio output. Based on the measured value from the measuring unit 200 at this time, the stationary weight W of the player is calculated (step A1). Next, based on the static weight W, a pulse detection threshold THa and a peak detection threshold THb are set (step A3).

  Also, a correspondence relationship between the orientation of the board-type controller 1300 and the orientation with respect to the player is set. That is, for example, by causing the player to move the center of gravity in a predetermined direction on the board-type controller 1300 by screen display, audio output, or the like, based on the measurement value from the measurement unit 200 at that time, The correspondence between the left-right direction and the orientation of the board type controller 1300 is determined (step A5). Further, a game space that is a slope is set in the virtual three-dimensional space, and various characters such as the player character PC are arranged in the game space (step A7). Thereafter, the game is started (step A9).

  During the game, it is determined whether or not the player character PC is sliding. If the player character PC is sliding (step A11: YES), the operation detection unit 312 determines the center of gravity position R of the player based on the measurement value by the measurement unit 200. Calculate (step A13). Further, based on this measurement value, it is determined whether a jump instruction operation has been detected (step A15).

  If the jump instruction operation is not detected (step A17: NO), the player character control unit 314 determines the action centroid vector R1 based on the calculated centroid position R (step A35), and the determined action centroid. The next velocity vector V1 is calculated based on the vector R1 (step A37). Then, the player character PC is controlled according to the calculated velocity vector V1 (step A39).

  On the other hand, if a jump instruction operation is detected (step A17: YES), the operation detection unit 312 detects the amount of change in the measured value due to this jump instruction operation (step A19). Next, the player character control unit 314 determines the action gravity center vector R2 based on the calculated gravity center position R (step A21). Further, the jump vector H is determined based on the change amount of the measured value by the jump instruction operation (step A23). Then, the next velocity vector V1 is calculated based on the determined action centroid vector R2 and jump vector H (step A25).

  Subsequently, based on the calculated velocity vector V1, the movement trajectory of the player character PC when jumping according to the velocity vector V1 is calculated (step A27). Further, the estimated landing time tn and the estimated landing position Pn when moving (jumping) along the calculated movement trajectory are calculated (step A29), and a landing operation reception period T3 including the estimated landing time tn is set (step A31). ). Thereafter, the jump action of the player character PC along the calculated movement trajectory is started (step A33).

  If the player character PC is jumping (step A11: NO), the player character control unit 314 performs character movement control along the calculated movement trajectory (step A41).

  If the current time is within the landing operation reception period T3 (step A43: YES), the operation detection unit 312 determines whether a landing instruction operation is detected based on the measurement value by the measurement unit 200 (step A45). . If the landing instruction operation is detected (step A47: YES), the player character control unit 314 sets the landing action flag to “1” (step A49).

  If the current time reaches the scheduled landing time tn (step A51: YES), the landing instruction flag is determined. If the landing operation flag is set to “1” (step A53: YES), the player The character PC is caused to perform a special landing action (step A55). On the other hand, if the landing motion flag is set to “0” (step A53: NO), the player character PC is caused to perform a normal landing motion (step A57). Subsequently, the landing operation flag is set (cleared) to “0” (step A59).

  Thereafter, it is determined whether or not to end the game. If not ended (step A61: NO), the process returns to step A11, and if ended (step A61), the game process is ended.

[Modification]
It should be noted that embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention.

(A) Detection of jump / landing instruction operation For example, a change in a measured value centered on the stationary weight W may be detected as a jump / landing instruction operation. Specifically, the measurement value vibration, which is a phenomenon in which the change in the change amount with respect to the stationary weight W as a reference reaches the increase / decrease reference amount ΔWa alternately occurs in the increasing direction and the decreasing direction, continues for a predetermined time. This is detected as a jump / landing instruction operation.

(B) Reference increase / decrease amount ΔWa
Further, the reference increase / decrease amount ΔWa for setting the threshold values TH _a1 and TH _a-1 for pulse detection may be different between the increasing direction and the decreasing direction of the measurement value. Specifically, a reference increase or decrease the amount ΔW increasing direction of the measurement value and increases or decreases the reference amount DerutaWa _+, reducing the reference increase or decrease the amount ΔW of decreasing direction reference quantity DerutaWa _- to. Then, as the threshold value THa for pulse detection, and sets the reference increment DerutaWa ₊ only large increment threshold THa ₁ than the static weight W, reference decrease amount DerutaWa _- sets only a small amount of decrease threshold _{THa -1.}

(C) Center-of-gravity movement instruction operation In the above-described embodiment, the center-of-gravity position R of the player is detected as one of the load balances. For example, the direction of bias of the center of gravity is determined from the relative magnitude of the measured values of the four pressure sensors 1302. Specifically, the direction from the reference position O of the board-type controller 1300 toward the position of the sensor 1302 having the maximum measured value is defined as the direction of bias of the center of gravity. Furthermore, the measurement value of the sensor 1302 having the largest measured value may be set as the magnitude (degree) of the bias, or the difference between the minimum measured value and the maximum measured value may be set as the magnitude of the bias. Alternatively, the direction from the position of the sensor 1032 having the smallest measured value to the position of the largest sensor 1302 may be set as the direction of bias of the center of gravity. When determining the acting gravity center vectors R1 and R2 based on the load balance, the working gravity vector R1 indicates the direction of deviation of the gravity center as the Xc axis of the input coordinate system (Xc, Yc) of the board type controller 1300. The direction of line symmetry with respect to the direction is the direction, and the magnitude of the deviation is the size (length). In addition, regarding the acting gravity center vector R2, the direction of the center of gravity bias is the direction, and the size of the bias is the size (length).

(D) Trial of player operation Prior to the start of the game, the player is made to try the player operation including the jump instruction operation and the landing instruction operation, and the pulse determination threshold value THa is set according to the measured value at this time. You may decide to do it.

  Specifically, for example, the player's operation is attempted by displaying a model of an action to be performed by the player as a moving image and outputting the action point as a sound so that the player can practice it before starting the game. Then, based on the peak value (magnitude) of the pulse generated in the measured value of the pressure sensor 1302 at this time, the pulse determination threshold THa is set. That is, depending on the player such as an adult or a child, even if the same action is performed, the peak value (magnitude) of the pulse generated in the measurement value varies depending on the weight and the magnitude of the action. Therefore, when the peak value of the measurement value pulse is large, the increase / decrease reference amount ΔWa is increased, and the pulse detection threshold THa is set to a value away from the stationary weight W of the player. On the contrary, when the peak value of the pulse of the measured value is small, the increase / decrease reference amount ΔWa is decreased, the pulse detection threshold THa is set to a value close to the stationary body weight W, and the pulse detection sensitivity is increased. To do. This makes it possible to reliably detect jump instruction operations and landing instruction operations regardless of the player.

  Further, at this time, the peak threshold value Tb may be set according to the measured value of the pressure sensor 1302 at the time of the player operation trial. That is, when the peak value of the measurement value pulse is large, the increase / decrease reference amount ΔWb is increased to widen the interval between the peak detection thresholds THb, and conversely, when the peak value of the measurement value pulse is small Then, the increase / decrease reference amount ΔWb is decreased, and the interval between the peak detection thresholds THb is decreased.

(E) Error notification Further, when it is detected that the player PL has jumped or descended on the board type controller 1300 during the game, the progress of the game may be stopped. When the player jumps on the board-type controller 1300 or descends from the board-type controller 1300, the measured value of the pressure sensor 1302 decreases rapidly. Specifically, the measured value is almost zero when jumping or when both feet are released completely, and when one foot is lowered, the measured value is halved compared to when riding with both feet. To do.

  Therefore, a value close to zero (for example, 10 kg) or a predetermined ratio (for example, 40%) of the stationary weight W is set as the threshold value THc at the time of warning. When the time when the measured value of the pressure sensor 1302 falls below the threshold value THc reaches a predetermined time (for example, 0.5 seconds), the player jumps on the board type controller 1300 or falls from the board type controller 1300. Judgment is made, the game in progress is stopped, and a predetermined warning message is output by screen display or voice output.

  Also, when it is detected that another player has further boarded the board-type controller 1300, the progress of the game may be stopped. When another player rides on the board-type controller 1300, the measurement value of the pressure sensor 1302 increases rapidly (doubles), and the period during which the measurement value increases continues. Therefore, a value about twice the stationary weight W of the player is set as the threshold value THd at the time of warning. When the time when the measured value of the pressure sensor 1302 exceeds the threshold value THd reaches a predetermined time (for example, 2.0 seconds), it is determined that another player is on the board-type controller 1300, and the game in progress And a predetermined warning message is output by screen display, audio output, or the like.

(F) Action of player character to be applied and type of game In the above-described embodiment, it has been described that the player character performs a jump action in response to a jump operation instruction. For example, when the player character is a pitcher of a baseball game and the player character throws a ball, the present invention is applied, and in response to an input of an “operation instruction” corresponding to the “jump operation instruction” described in the above embodiment, Causes the player character to perform a ball throwing action. The speed and moving direction of the ball thrown by the player character can be calculated by the same method as in the above-described embodiment. That is, it is possible to control such that the moving direction of the ball to be thrown is controlled according to the load balance when the “operation instruction” is given, and the speed of the ball is adjusted according to the magnitude of the measurement value of the pressure sensor 1302. Of course, the present invention is applied to a game such as a skateboard game, a ski game, or a roller skateboard similar to the snowboard game of the above-described embodiment, and a player character is given a response to an “operation instruction” corresponding to a “jump operation instruction”. It may be controlled to activate various trick actions
