[composition]
FIG. 1 is a diagram showing an example of an information processing system 1 of the present embodiment. The information processing system 1 includes a head mounted display 10 and an operator 100 that perform processing for realizing so-called XR, and a server device 20 or a personal computer 30 that provides various data and programs to the head mounted display 10. The head mounted display 10 and the operator 100 are communicably connected to each other by short-distance wireless communication such as Bluetooth (registered trademark) or a communication cable. The head mounted display 10 and the server device 20 are communicably connected to each other by a network 2. The head mounted display 10 and the personal computer 30 are communicably connected to each other by short-distance wireless communication such as Bluetooth (registered trademark) or a communication cable, or a network not shown. The network 2 is, for example, a LAN (Local Area Network) or a WAN (Wide Area Network), or a combination of these, and includes a wired section or a wireless section. The head mounted display 10 downloads various data and programs from the server device 20 or the personal computer 30, and uses these to realize XR in a so-called standalone manner. In this embodiment, a case in which VR (virtual reality) is realized will be described as an example of XR. That is, the head mounted display 10 displays virtual objects in a virtual three-dimensional space.

Using the head-mounted display 10 and the controller 100, the user can play a game of hitting a virtual object in a virtual three-dimensional space with a virtual tool. In this embodiment, the game is badminton. That is, the user hits a virtual shuttlecock, an object corresponding to a virtual object, with a virtual racket, an object corresponding to a virtual tool, to play badminton with a virtual character, an object corresponding to a virtual opponent. The virtual racket is operated by the controller 100 that the user holds and moves in his/her hand. That is, the user can hit the virtual shuttlecock displayed in the virtual three-dimensional space by the head-mounted display 10 by performing an action as if hitting the virtual shuttlecock with the controller 100 held in his/her hand.

2 is a diagram illustrating an example of the hardware configuration of the head mounted display 10 and the operator 100. The head mounted display 10 functions as an example of an information processing device according to the present invention. The head mounted display 10 is an information processing device of a type that is worn on the user's head, but is not limited to this, and may be, for example, a contact lens type wearable computer, or a portable computer such as a smartphone or tablet. The head mounted display 10 is physically configured as a computer including a processor 1001, a memory 1002, a storage 1003, a communication device 1004, an input device 1005, an output device 1006, a display device, an imaging device 1008, and a bus connecting these. In the following description, the word "apparatus" can be read as a circuit, a device, a unit, etc. The hardware configuration of the head mounted display 10 may be configured to include one or more of the devices shown in the figure, or may be configured without including some of the devices.

The functions of the head mounted display 10 are realized by loading specific software (programs) onto hardware such as the processor 1001 and memory 1002, causing the processor 1001 to perform calculations, control communication by the communication device 1004, display by the display device, and image capture by the image capture device 1008, and control at least one of reading and writing data in the memory 1002 and storage 1003.

The processor 1001, for example, operates an operating system to control the entire computer. The processor 1001 may be configured with a central processing unit (CPU) including an interface with peripheral devices, a control device, an arithmetic unit, a register, etc. Also, for example, a baseband signal processing unit, a call processing unit, etc. may be realized by the processor 1001.

The processor 1001 reads out programs (program codes), software modules, data, etc. from at least one of the storage 1003 and the communication device 1004 into the memory 1002, and executes various processes according to these. The programs used are those that cause a computer to execute at least a portion of the operations described below. The functional blocks of the head mounted display 10 may be realized by a control program stored in the memory 1002 and running on the processor 1001. The various processes may be executed by one processor 1001, or may be executed simultaneously or sequentially by two or more processors 1001. The processor 1001 may be implemented by one or more chips. The programs may be transmitted from the network 2 to the head mounted display 10 via an electric communication line.

The memory 1002 is a computer-readable recording medium, and may be composed of at least one of, for example, a ROM (Read Only Memory), an EPROM (Erasable Programmable ROM), an EEPROM (Electrically Erasable Programmable ROM), a RAM (Random Access Memory), etc. The memory 1002 may also be called a register, a cache, a main memory (primary storage device), etc. The memory 1002 can store executable programs (program codes), software modules, etc. for implementing the method according to this embodiment.

Storage 1003 is a computer-readable recording medium, and may be composed of at least one of, for example, an optical disk such as a CD-ROM (Compact Disc ROM), a hard disk drive, a flexible disk, a magneto-optical disk (e.g., a compact disk, a digital versatile disk, a Blu-ray (registered trademark) disk), a smart card, a flash memory (e.g., a card, a stick, a key drive), a floppy (registered trademark) disk, a magnetic strip, etc. Storage 1003 may also be called an auxiliary storage device.

The communication device 1004 is hardware (transmitting/receiving device) for communicating between computers via at least one of a wired network or a wireless network, and is also called, for example, a network device, a network controller, a network card, or a communication module. The communication device 1004 includes a communication device that communicates via the network 2 and a communication device that communicates with the operator 100. The communication device 1004 may be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc., to realize at least one of frequency division duplex (FDD: Frequency Division Duplex) or time division duplex (TDD: Time Division Duplex). For example, the transmitting/receiving antenna, an amplifier unit, a transmitting/receiving unit, a transmission line interface, etc. may be realized by the communication device 1004. In this embodiment, the transmitting/receiving unit may be implemented as a transmitting unit and a receiving unit that are physically or logically separated.

The input device 1005 is an input device (e.g., a key, a microphone, a switch, a button) that accepts input from the outside. The output device 1006 is an output device that outputs to the outside, and includes a display device consisting of a liquid crystal element and a liquid crystal drive circuit, as well as a speaker and an LED lamp.

Each device, such as the processor 1001 and memory 1002, is connected by a bus for communicating information. The bus may be configured using a single bus, or may be configured using different buses between each device.

The head mounted display 10 may also be configured to include hardware such as a microprocessor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a programmable logic device (PLD), or a field programmable gate array (FPGA), and some or all of the functional blocks may be realized by the hardware. For example, the processor 1001 may be implemented using at least one of these pieces of hardware.

The controller 100 has, for example, a rod-like appearance, and includes a detection device 1011 such as a gyro sensor or acceleration sensor that detects the behavior of the controller 100, a communication device 1012 that communicates with the head-mounted display 10, and a processor 1013 and memory (not shown) that control these. Because the controller 100 is operated while held in the user's hand, the behavior of the controller 100 can be considered as the user's movement. In other words, the detection device 1011 of the controller 100 functions as a detection device that detects the user's movement. The detection result of the detection device 1011 is transmitted to the head-mounted display 10 by the communication device 1012.

Fig. 3 is a block diagram showing an example of the functional configuration of the head mounted display 10. As shown in Fig. 3, the head mounted display 10 realizes functions such as an acquisition unit 11, a display control unit 12, and a setting unit 13.

The acquisition unit 11 acquires the detection results from the operator 100, i.e., the detection device 1011 that detects the user's actions.

The display control unit 12 causes the display device 1007 to display a virtual image that mimics a badminton game in which a virtual shuttlecock is hit with a virtual racket, in accordance with the detection result acquired by the acquisition unit 11. In other words, the display control unit 12 causes the display device 1007 to display objects such as a virtual shuttlecock, a virtual racket, and a virtual character.

The setting unit 13 sets parameters that determine the size of the virtual hitting surface of the virtual racket operated by the user where the virtual shuttlecock will hit, and parameters for determining the virtual trajectory of the virtual shuttlecock hit by the user's operation in virtual three-dimensional space. Here, the setting unit 13 sets these parameters according to the situation in the game of badminton. Specifically, the setting unit 13 sets the above parameters according to the direction of the user's movement when moving to hit the virtual shuttlecock with the virtual racket.

Here, we will use Figures 4 to 8 to explain the relationship between the direction of movement (called the racket swing direction) when the user moves to hit the virtual shuttlecock with the virtual racket, and the parameters that determine the size of the virtual hitting surface on the virtual racket where the virtual shuttlecock will hit.

Figure 4 is a diagram showing an example of an image displayed on the display device 1007 when the head mounted display 10 is activated and virtual badminton is started. As shown in the figure, an opponent virtual character G1 is displayed on the other side of a virtual net G3 in the field of view of a user wearing the head mounted display 10 on his or her head. The virtual character G1 holds a virtual racket G2 and hits a virtual shuttlecock with this virtual racket G2.

Figure 5 is a diagram illustrating the relationship between a virtual racket operated by a user and the hitting surface of a virtual shuttlecock on the virtual racket (called a virtual hitting surface). Generally, a badminton racket consists of an elliptical face with a net stretched over it and a rod-shaped handle held by the user. In this structure, when the shuttlecock hits the face, the elastic force of the net causes the shuttlecock to bounce far away. In other words, the face with the net stretched over it corresponds to the virtual hitting surface of the shuttlecock. Meanwhile, in this embodiment, the virtual hitting surface can be set to any size for the face of the virtual racket. That is, as illustrated in Figure 5, a virtual hitting surface A of a size as shown by a dashed line can be set for the face part g of the virtual racket G shown by a solid line. The size of the virtual hitting surface is determined by a parameter for determining it (for example, an equation representing a closed curve corresponding to the outer edge of the virtual hitting surface A).

6 to 8 are diagrams illustrating the relationship between the direction in which the user swings the virtual racket (i.e., the direction in which the controller 100 is swung, the racket swing direction) and the virtual hit surface. For example, in badminton, there are multiple ways to hit the shuttlecock, such as smash, clear, and drop. For example, in real-world badminton, when an opponent hits the shuttlecock with a clear hit, the shuttlecock follows a trajectory that makes it appear to be falling from above the user's head, so the user swings the racket up and hits the shuttlecock in time to hit it forward as it falls. The inventors performed simulations and experiments by setting the size of the virtual racket face to match the size of the virtual hit surface, and found that it is difficult for the user to hit the virtual shuttlecock when the opponent's virtual character hits it with the above-mentioned clear.

Therefore, as shown in FIG. 6, when the user swings his/her virtual racket G up and swings it forward or downward, the size of the virtual hitting surface A is made larger than the size of the face part g of the virtual racket. The racket swing direction (direction S in the figure) in which the virtual racket is swung up and swings forward or downward is a direction included in the range X between the dashed lines D1 and D2. These dashed lines D1 and D2 are half lines extending in a direction of 15 degrees to the left and right of the user, for example, when viewed from an axis extending vertically upward with the origin O being the viewpoint (position of the head-mounted display 10) of the user facing the virtual net. At this time, for example, the center position of the ellipse of the face part g and the center position of the ellipse of the virtual hitting surface A are kept aligned, and the long and short axes of the ellipse of the virtual hitting surface a are made larger. At this time, the rate at which the long axis of the ellipse of the virtual hitting surface a is made larger may be made larger than the rate at which the short axis of the ellipse of the virtual hitting surface a is made larger.

Therefore, when an action is performed in a range other than the range X illustrated in FIG. 6, specifically, when an action is performed such as swinging the virtual racket in the direction S illustrated in FIGS. 7 and 8, the size of the face part g of the virtual racket G and the size of the virtual hitting surface A are made the same. For example, FIG. 7 shows an example of an action in which the user swings the virtual racket horizontally to the side of his/her body, and FIG. 8 shows an example of an action in which the user swings the virtual racket from below to above as if scooping up a virtual shuttlecock that falls in front of him/her. The size of the virtual hitting surface illustrated in FIGS. 7 and 8 is smaller than the size of the virtual hitting surface illustrated in FIG. 6. This is because it is easier for the user to return a virtual shuttlecock that has been hit by an opponent with a hit other than a clear hit (for example, a drop in which the shuttlecock falls in front of the user as described above) than to return a virtual shuttlecock that has been hit by an opponent with a clear hit.

The parameters for determining the trajectory of the virtual shuttlecock when the user hits it with the virtual racket are also set according to the same concept as above. In other words, when the user raises his/her virtual racket and swings it forward or downward, the trajectory of the virtual shuttlecock is calculated using parameters that increase the probability that the virtual shuttlecock will cross the virtual net and reach the court on the virtual character's side, compared to when the user swings the virtual racket in any other direction. The parameters referred to here are, for example, an equation that shows the trajectory of the virtual shuttlecock, and various coefficients and constants in that equation.

The setting unit 13 stores a table as shown in FIG. 9. In this table, the direction of swinging the virtual racket (racket swing direction), a parameter (called a hit surface parameter) that determines the size of the virtual hit surface of the virtual racket where the virtual shuttlecock hits the virtual racket, and a parameter (called a trajectory parameter) that determines the virtual trajectory of the hit virtual shuttlecock in a virtual three-dimensional space are stored in association with each other. In the example shown in the figure, when the user performs a racket swing direction motion that corresponds to the range X as described above, the hit surface parameter Pa1 and the trajectory parameter Pb1 are set, and when the user performs a racket swing direction motion that corresponds to a range other than the range X, the hit surface parameter Pa2 and the trajectory parameter Pb2 are set. The hit surface parameter Pa1 is a parameter for determining a virtual hit surface that is larger than the hit surface parameter Pa2. In addition, the trajectory parameter Pb1 is a parameter that increases the probability that the virtual shuttlecock hit by the user will reach the court on the virtual character side over the virtual net compared to the trajectory parameter Pb2. The setting unit 13 sets the hit plane parameters and trajectory parameters by referencing the contents of this table and the detection results of the controller 100.

As described above, in this embodiment, the head mounted display 10 performs operations related to image display in a standalone manner without being controlled by the server device 20 or the personal computer 30, and therefore the functional configuration is as shown in FIG. 3. However, the head mounted display 10 may also perform operations related to image display in cooperation with the server device 20 or the personal computer 30.

[Action]
An example of the operation of the head mounted display 10 will be described with reference to Fig. 10. First, when the user starts the head mounted display 10, the processor 1001 executes a program to display each virtual object in a virtual three-dimensional space and allows the user to start playing badminton. The game is started, for example, when a virtual shuttlecock is hit from a virtual character toward the user. The controller 100 periodically transmits the detection result detected by the detection device 1011 to the head mounted display 10. In the head mounted display 10, the acquisition unit 11 acquires the detection result from the controller 100 (step S11).

Next, the display control unit 12 analyzes the detection result acquired by the acquisition unit 11 and determines whether or not the user has performed a swing motion with the virtual racket to strike the virtual shuttlecock that has been hit from the virtual character toward the user (step S12). If the motion is other than that corresponding to such a racket swing (step S12; NO), the corresponding process is executed in the head-mounted display 10 (step S16).

On the other hand, if the movement corresponds to a racket swing (step S12; YES), the setting unit 13 determines the racket swing direction (step S13). The setting unit 13 then reads out from the table and sets the hit plane parameters and trajectory parameters corresponding to the determined racket swing direction (step S14). In other words, if it is determined that the racket swing direction corresponds to range X as described above, the hit plane parameter Pa1 and trajectory parameter Pb1 are set, and if it is determined that the racket swing direction corresponds to a range other than range X, the hit plane parameter Pa2 and trajectory parameter Pb2 are set.

Then, the display control unit 12 causes the display device 1007 to display the virtual shuttlecock that has been hit by the user with the virtual racket, in accordance with the hit surface parameters and trajectory parameters that correspond to the detection results and that are set by the setting unit 13 (step S15). The above process is repeated each time a detection result is obtained.

According to the embodiment described above, when a user plays a game in which the user hits a virtual object with a virtual tool through his or her own movements, the difficulty level at which the user hits the object changes depending on the situation of the game, making it easier for the user to enjoy the game.

[Modification]
The present invention is not limited to the above-described embodiment. The above-described embodiment may be modified as follows. In addition, two or more of the following modifications may be combined and implemented.
[Modification 1]
The setting unit 13 may set only one of the hit surface parameter and the trajectory parameter according to the detection result. The setting unit 13 may set the hit surface parameter or the trajectory parameter according to the situation in the game, and this setting may be performed in the following cases. For example, as described above, there are multiple ways of hitting in badminton, such as smash, clear, and drop. Therefore, the above parameters may be set according to the way of hitting by the opponent, that is, the type of hit from the virtual character. For example, when the hit from the opponent is a clear, the setting unit 13 sets a hit surface parameter that increases the size of the virtual hit surface or a trajectory parameter that increases the probability of reaching the opponent's court, compared to when the hit from the opponent is not a clear. It is possible to determine whether the hit from the opponent is a clear or not by referring to the program code being executed. This makes it easy for the user to hit back the virtual shuttlecock that has been hit by a clear, which is assumed to be difficult for the user to hit back. In this way, the setting unit 13 may set the parameters according to the type of hit on the target by the virtual character with which the user plays.

[Modification 2]
It can also be said that the trajectory of the virtual shuttlecock hit by the opponent varies depending on the hitting methods in badminton, such as smash, clear, and drop. In other words, the above parameters may be set according to the trajectory of the virtual shuttlecock hit by the virtual character. For example, when the hit from the opponent is a clear, and the trajectory is an arc that falls from above the user's head, the setting unit 13 sets a hitting surface parameter that increases the size of the virtual hitting surface or a trajectory parameter that increases the probability of reaching the opponent's court, compared to a trajectory other than the clear. The trajectory of the virtual shuttlecock hit by the opponent can be determined by referring to the program code being executed. This makes it easier for the user to hit back a virtual shuttlecock that is difficult for the user to hit back, such as a trajectory that falls from above the user's head and draws an arc. In this way, the setting unit 13 may set the parameters according to the trajectory of the object hit by the virtual character with which the user plays.

[Modification 3]
It can also be said that the position to which the virtual shuttlecock hit by the opponent flies varies depending on the above-mentioned hitting methods in badminton, such as smash, clear, and drop. For example, in the case of a clear, the virtual shuttlecock arrives above the user's head, and in the case of a drop, the virtual shuttlecock arrives in front of the user. Therefore, the above parameters may be set according to the position to which the virtual shuttlecock hit by the virtual character arrives. For example, when the hit from the virtual character reaches a position above the user's head, such as a clear, the setting unit 13 sets a hitting surface parameter that increases the size of the virtual hitting surface or a trajectory parameter that increases the probability of the virtual shuttlecock reaching the opponent's court, compared to cases other than the clear. The position to which the virtual shuttlecock hit by the opponent flies can be determined by referring to the execution result of a program for calculating the trajectory of the virtual shuttlecock. This makes it easy for the user to hit back a virtual shuttlecock that is difficult for the user to hit back, such as one that reaches above the user's head. In this way, the setting unit 13 may set the parameters according to the position to which an object hit by a virtual character with whom the user plays reaches in the virtual three-dimensional space.

[Modification 4]
The head mounted display 10 may store the accumulated period during which the user has played the game, and set the above parameters according to the accumulated period. For example, when the accumulated period exceeds a threshold, the setting unit 13 sets a hitting surface parameter that increases the size of the virtual hitting surface or a trajectory parameter that increases the probability of reaching the opponent's court, compared to when the accumulated period is equal to or less than the threshold. This allows the difficulty level to be set according to the user's gaming experience. In this way, the setting unit 13 may set the parameters according to the period during which the user has played the game of hitting a virtual object with a virtual tool. In other words, in the present invention, the situation in the game includes the concept of the accumulated period during which the user has played the game.

[Modification 5]
The head mounted display 10 may store the number of times the user hits an object in a game, and set the above parameters according to the number of times. For example, when the number of times exceeds a threshold, the setting unit 13 sets a hit surface parameter that increases the size of the virtual hit surface or a trajectory parameter that increases the probability of reaching the opponent's court, compared to when the number of times is equal to or less than the threshold. This allows the difficulty level to be set according to the user's hitting proficiency. In this way, the setting unit 13 may set the parameters according to the number of times the user hits a virtual object with a virtual tool. In other words, in the present invention, the situation in a game includes the concept of the number of times the user hits an object in a game.
