Description

  The present invention relates to a game program and a game system that are executed by a computer provided with a head mounted display that displays digital information.

  Conventionally, a virtual reality (VR) type game in which a user operates a character or the like disposed in a virtual space while viewing an image of the virtual space displayed on a head mounted display mounted on the head of the user is known. It is done. Even in such a game, various input operations are generally performed by a controller held and operated by the user as in a normal game system (for example, see Patent Document 1 below).

  In addition to the input operation by such a controller, the aspect which judges the user's gaze direction (gaze direction), and selects and operates the object located ahead of the said gaze direction is proposed (refer following patent document 2).

JP, 2017-6355, A JP 2017-58971 A

  However, as in Patent Document 1, with a controller held and operated by the user, an intuitive operation to the game can not be performed, and the feeling of immersion may be cut off. For example, in a situation where a conversation with a plurality of characters is desired, an operation to select the one character from among the plurality of characters (a cursor key movement operation, etc.) ), It is necessary to perform an operation (a predetermined button pressing operation or the like) for performing an agreeing operation. The operation by such a controller takes time, and the conversation is interrupted at each operation.

  On the other hand, in the above-described mode in which an object in the direction of the user's line of sight is selected and operated, there is a problem that erroneous operation is likely to occur. Depending on the user, the user can not maintain the line of sight on the object he / she wants to select, so selection errors are likely to occur, or the selection operation can not easily be performed.

  The above problems may occur not only in VR games but also in alternative reality (SR), augmented reality (AR) or mixed reality (MR) games.

  Therefore, an object of the present invention is to provide a game program and a game system capable of performing an intuitive input operation while suppressing an erroneous operation in a game executed by a game system using a head mounted display.

  In order to solve the above problems, a game program according to an aspect of the present invention is a game program to be executed by a computer provided with a head mounted display for displaying digital information, and the computer includes information on the head mounted display. Eye-gaze acquisition means for acquiring the position of a virtual line of sight extending forward from a predetermined reference position set in the display area, and a judgment area for setting a virtual judgment area at a predetermined position in a space visible to the user through the head mounted display It functions as setting means and input operation determination means for determining whether or not a predetermined input operation has been performed based on the crossing manner of the virtual line of sight into the determination area.

  The head mounted display is configured to display the virtual space photographed by a virtual camera as a pair of virtual two-dimensional images having parallax so that a user can stereoscopically view a three-dimensional virtual space, and the computer is an object Virtual space generation means for generating the virtual space in which the virtual camera is arranged; virtual camera movement means for moving the virtual camera in the virtual space according to the movement of the head of the user on which the head mount display is mounted It may be made to function.

  The determination area may be set to a predetermined virtual object displayed in the information display area.

  The determination area is set to a game interruption object disposed in the virtual space, and it is determined that the computer has performed a predetermined input operation on the determination area set to the game interruption object. In this case, it may function as an interruption process execution means for interrupting the game being executed.

  The determination area is defined by an upper limit border, a lower limit border, a left limit border, and a right limit border, and the input operation determining means determines that the virtual line of sight is the upper limit border and the lower limit border for a predetermined period. When it is determined that the first input operation has been performed when the virtual line of sight intersects the left limit boundary line and the right limit boundary line for a predetermined period of time in a predetermined period, It may be determined that a second input operation different from the one input operation has been performed.

  A game system according to another aspect of the present invention includes a program storage unit storing the above-described game program, and a computer that executes a program stored in the program storage unit.

  According to the present invention, it is possible to provide a game program and a game system capable of performing an intuitive input operation while suppressing an erroneous operation in a game executed by a game system using a head mounted display.

It is a figure which shows an example of the game screen displayed on HMD in this Embodiment.

  Hereinafter, a game program and a game system according to an embodiment of the present invention will be described with reference to the drawings. In the following, the VR type game is mainly described.

[Hardware configuration]
FIG. 1 is a block diagram showing the hardware configuration of the game system in the present embodiment. The game system 1 includes a game device 2 and a server device 3. The game devices 2 can communicate with each other between the other game devices 2 and the server device 3 via a communication network NW such as the Internet or a LAN. The game apparatus 2 comprises a CPU 10 which is a computer for controlling the operation of the game apparatus 2. The CPU 10 has a disk drive 12, a memory card slot 13 and an HDD 14 and ROM 15 forming a storage unit (program storage unit). And the RAM 16 is connected.

  The disk drive 12 can be loaded with a disk-type recording medium 30 such as a DVD-ROM. A game program 30a and game data 30b according to the present embodiment are recorded on the disc type recording medium 30. The game data 30 b includes various data necessary for the progress of the game, such as data necessary for forming a virtual space and sound data reproduced in the game. In addition, a card type recording medium 31 can be loaded into the memory card slot 13, and save data indicating a play status such as progress of a game can be recorded according to an instruction from the CPU 10.

  The HDD 14 is a large-capacity recording medium built in the game apparatus 2 and records the game program 30a and the game data 30b read from the disk type recording medium 30, and further save data and the like. The ROM 15 is a semiconductor memory such as a mask ROM or a PROM, and stores an activation program for activating the game apparatus 2 and a program for controlling the operation when the disc type recording medium 30 is loaded. The RAM 16 is composed of a DRAM or SRAM, and reads from the disk type recording medium 30 or the HDD 14 the game program 30a to be executed by the CPU 10 and the game data 30b required for the execution according to the game play status. Temporarily record at.

  Furthermore, the HMD interface 17, the light detection device interface 18, the graphic processing unit 19, the audio synthesizing unit 20, the audio interface 21, the wireless communication control unit 22, and the network interface 23 are connected to the CPU 10 via the bus 11. It is done. A head mounted display (hereinafter HMD) 40, a light detection device 46 and a headphone 47 are connected to the HMD interface 17, the light detection device interface 18 and the audio interface 21, respectively.

  The HMD 40 can be worn on the head of the user. The HMD 40 includes a pair of display units 41 (41a and 41b), an acceleration sensor 42, a gyro sensor 43, a light emitting unit 44, and a control unit 45. By mounting the HMD 40 on the head of the user, the display unit 41a for the left eye and the display unit 41b for the right eye are respectively disposed in front of the left eye and the right eye of the user. A light shielding partition (not shown) is provided between the display unit 41 a for the left eye and the display unit 41 b for the right eye.

  The acceleration sensor 42 and the gyro sensor 43 constitute a motion detection system that detects the motion of the user's head. The acceleration sensor 42 detects, for example, the orientation of the HMD 40 with respect to the direction of gravity, that is, the tilt of the head of the user. The gyro sensor 43 detects, for example, the angular velocity of the HMD 40, that is, the speed at which the user tilts or rotates the head. Motion information obtained from the acceleration sensor 42 and the gyro sensor 43 is sent to the graphic processing unit 19 and the audio synthesis unit 20 via the HMD interface 17.

  The light emitting unit 44 of the HMD 40, together with the light detection device 46, constitutes a position detection system that detects the position of the head of the user. In the present embodiment, the light emitting portions 44 are, for example, a plurality of LED lights provided in the HMD 40 so as to be separated from each other. The light detection device 46 is fixedly disposed, for example, in front of the user, and detects the position of light emitted from the light emitting unit 44 of the HMD 40. The light detection device 46 detects the position of the light emitted from the light emitting unit 44 to acquire position information of the head of the user relative to the light detection device 46. The position information may be used to correct the motion information described above. The position information obtained from the light detection device 46 is sent to the graphic processing unit 19 and the audio synthesis unit 20 via the light detection device interface 18.

  In addition, the position detection system which detects the position of a user's head is not limited to this. For example, a light sensor may be provided on the HMD 40 side, and the position of the head of the user may be detected by detecting light emitted from a light emitting device disposed around the user with the light sensor.

  The control unit 45 controls various devices included in the HMD 40, such as transmission of data from the acceleration sensor 42 and the gyro sensor 43 to the game apparatus 2 and transmission of a signal to the light emitting unit 44.

  The graphic processing unit 19 draws a game image including a three-dimensional virtual game space and the like according to an instruction of the CPU 10. For example, the graphic processing unit 19 generates a pair of virtual two-dimensional images having a parallax so that the user can stereoscopically view a three-dimensional virtual space. That is, the graphic processing unit 19 generates a virtual two-dimensional image for the left eye and for the right eye which has parallax and is photographed by each of the pair of virtual cameras arranged in the virtual three-dimensional space. Then, the pair of virtual two-dimensional images is converted into a moving image format, sent to the HMD 40 through the HMD interface 17, and displayed on the pair of display units 41a and 41b. Also, the graphic processing unit 19 transmits to the HMD 40 in real time in accordance with the motion information and position information about the user sent from the HMD 40 and the light detection device 46 so as to give the user a sense of presence as if entering the virtual space. Change a pair of virtual two-dimensional images.

  The audio synthesizing unit 20 reproduces and synthesizes digital format sound data included in the game data 30 b according to an instruction of the CPU 10. The sound data reproduced and synthesized by the audio synthesizing unit 20 is decoded into an analog format, and then sent to and output from the headphone 47 through the audio interface 21. As a result, the user playing the game can listen to the reproduced sound. The headphones 47 may be configured integrally with the HMD 40. Also, the audio synthesis unit 20 is output from the headphone 47 in real time in accordance with the motion information and position information sent from the HMD 40 and the light detection device 46 so as to give the user a sense of presence as if entering the virtual space. Sound may be changed. A speaker may be connected to the audio interface 21 instead of the headphone 47.

  The wireless communication control unit 22 has a wireless communication module in the 2.4 GHz band, is wirelessly connected to the controller 48 attached to the game apparatus 2, and can transmit and receive data. The user can input a signal to the game apparatus 2 by operating an operation unit such as a button provided on the controller 48.

  The network interface 23 connects the game device 2 to a communication network NW such as the Internet or LAN, and can communicate with other game devices 2 and the server device 3. Then, by connecting the game apparatus 2 to another game apparatus 2 via the communication network NW and transmitting / receiving data to / from each other, it is possible to perform multiplay to progress the game synchronously in the same virtual space. .

[Functional configuration of game system]
FIG. 2 is a block diagram showing a functional configuration of a control unit provided in the game system shown in FIG. FIG. 2 mainly shows functions required to realize the above-described game system. As described above, the game apparatus 2 operates as a computer including the CPU 10, the ROM 15, the RAM 16, the graphic processing unit 19, the audio synthesis unit 20, the wireless communication control unit 22, and the like. The computer of the game apparatus 2 constitutes a control unit 50 of the game system 1. The control unit 50 of the game system 1 operates based on the game program 30a and the game data 30b read from the disk-type recording medium 30, and has functions as described below.

  That is, the control unit 50 performs functions such as the line-of-sight acquisition unit 51, the determination area setting unit 52, the input operation determination unit 53, the virtual space generation unit 54, the virtual camera moving unit 55, the interruption processing execution unit 56, and the game control unit 57. Do.

  The virtual space generation unit 54 generates a three-dimensional virtual space. In this virtual space, various objects (virtual objects) such as non-player characters and items are arranged. Further, in the virtual space, a pair of virtual cameras are arranged.

  The virtual camera moving means 55 moves a pair of virtual cameras in the virtual space. In the present embodiment, the virtual camera moving unit 55 moves the pair of virtual cameras in the virtual space in accordance with the movement of the head of the user on which the HMD 40 is mounted.

  The line-of-sight acquisition unit 51, the determination area setting unit 52, and the input operation determination unit 53 execute a swing input operation process for performing an input operation based on the movement of the HMD 40 accompanying the movement of the head of the user. The line-of-sight acquisition unit 51 acquires the position of a virtual line of sight extending forward from a predetermined reference position set in the information display area (the display unit 41 in the present embodiment) in the HMD 40. The determination area setting unit 52 sets a virtual determination area at a predetermined position in a space visible to the user through the HMD 40. The input operation determination means 53 determines whether or not a predetermined input operation has been performed based on the mode of intersection of the virtual sight line into the determination area.

  Further, the interruption process execution means 56 executes a game interruption process for interrupting the game being executed. The game control means 57 controls the action of the non-player character based on the user's input operation, a predetermined action pattern or the like, and advances the game.

  FIG. 3 is a conceptual diagram showing the relationship between the HMD and the virtual space in the present embodiment. The pair of display units 41a and 41b in the HMD 40 mounted on the head of the user U are set as the positions of the pair of virtual cameras. The virtual camera corresponding to the display unit 41a for the left eye captures a virtual space S between the left view right limit Ear and the left view left limit Eal illustrated in FIG. 3. The virtual camera corresponding to the display unit 41 b for the right eye captures a virtual space S between the right view right limit Ebr and the right view left limit Ebl illustrated in FIG. 3.

  In the present embodiment, as described above, stereoscopic vision is realized using a pair of virtual cameras. Therefore, the position (focus position) of the intersection point P of the virtual lines La and Lb extending forward from the reference positions Qa and Qb of the pair of display portions 41a and 41b in the HMD 40 has a plan view (a game shown in FIG. It is set as the position of the virtual line of sight) on the screen. For example, the reference positions Qa and Qb are set at the center positions of the display portions 41a and 41b. Note that the position P of the virtual line of sight may be a three-dimensional coordinate at the intersection point P, the depth direction is ignored as infinity, and the input operation determination is performed only at the remaining two-dimensional coordinate positions (plane coordinates on the game screen G). It may be

  FIG. 4 is a view showing an example of a game screen displayed on the HMD in the present embodiment. FIG. 4 shows the game screen G displayed on the display unit 41a for the left eye in FIG. The game screen displayed on the display unit 41b for the right eye also has substantially the same display content except for the shift for the parallax. In this example, a scene in which the non-player characters C1 and C2 and the user have a conversation is exemplified. Therefore, in the virtual space S, two non-player characters C1 and C2 are arranged at positions facing the user. Although the position P of the virtual line of sight is displayed as a pointer in FIG. 4, the position P of the virtual line of sight may not be displayed on the game screen.

[Sway input operation processing]
The gaze acquisition means 51 acquires the position P of the virtual gaze. The virtual camera moving means 55 displays a game screen according to the position P of the virtual line of sight on the display portions 41a and 41b. That is, the virtual camera moving means 55 displays the virtual space S such that the position P of the virtual line of sight is always positioned at the center of the game screen on each of the display portions 41a and 41b.

  The determination area setting means 52 sets a virtual determination area 61 at a predetermined position of the virtual space S which can be viewed by the user through the HMD 40. The determination area 61 is set to a predetermined object arranged in the virtual space S. In the example of FIG. 4, the determination area 61 is set in the vicinity of the face portion of each of the non player characters C1 and C2. The setting timing of the determination area 61 can be adopted as appropriate. For example, the determination area 61 may be set when the non player characters C1 and C2 appear or is set when the non player characters C1 and C2 are located less than a predetermined distance from the virtual position in the virtual space S of the user Alternatively, it may be set when the faces of the non-player characters C1 and C2 are positioned within a predetermined angle range from the state where they face the reference positions Qa and Qb.

  The determination area 61 has a predetermined planar shape (rectangle in the example of FIG. 4), and is set such that the planar shape is directly opposed on the game screen (the planar shape is not deformed). The determination area 61 is defined by an upper limit boundary line 61U, a lower limit boundary line 61D, a left limit boundary line 61L, and a right limit boundary line 61R.

  The input operation determination means 53 determines whether or not a predetermined input operation has been performed based on the manner of intersection of the virtual line of sight into the determination area 61. In the present embodiment, the input operation determination unit 53 determines that the first input operation is performed when the position P of the virtual line of sight intersects the upper limit boundary line 61U and the lower limit boundary line 61D a predetermined number of times in a predetermined period. If the position P of the virtual line of sight intersects the left limit boundary 61L and the right limit boundary 61R a predetermined number of times in a predetermined period, it is determined that a second input operation different from the first input operation is performed . For example, the position P of the virtual line of sight moves from the inside of the determination area 61 to the outside of the determination area 61 across the upper limit boundary line 61U and moves from outside the determination area 61 to the inside of the determination area 61 again across the upper limit boundary line 61U. The reciprocation of moving the lower limit boundary 61D from the inside of the determination area 61 to the outside of the determination area 61 and crossing the lower limit boundary 61D from the outside of the determination area 61 into the determination area 61 again is a predetermined period. For example, when one reciprocation or more is detected during the detection, it is determined that the first input operation has been performed. The minimum number of reciprocations may be 2 or more, or may be set to 1.5 reciprocations or the like.

  Thereby, for example, when the user U performs the first input operation on the non-player character C1 by raising and lowering the head so that the user U faces the non-player character C1 (face-on) It is judged. In addition, it is determined that the second input operation on the non-player character C1 is performed by waving the neck left and right while the user U faces the non-player character C1. For example, the first input operation is set as a positive answer operation to the corresponding non player character C1, and the second input operation is set as a negative answer operation to the corresponding non player character C1.

  For example, in FIG. 4, two non-player characters C1 and C2 individually propose to the user U an action to be performed from now on. The non-player character C1 proposes to go shopping. The non-player character C2 proposes to go to the park. When the user U wishes to agree with the proposal of the non-player character C1, the user moves the HMD 40 so as to face the non-player character C1, and then moves his head up and down as if to speak. Thereby, it is determined that the first input operation to the non player character C1 is performed, and it can be transmitted that the proposal of the non player character C1 is in favor.

  On the other hand, if it is desired to oppose the proposal of the non-player character C2, the HMD 40 is moved to face the non-player character C2, and then the head is swung from side to side. Thereby, it is determined that the second input operation to the non player character C2 is performed, and it can be conveyed that the proposal of the non player character C2 is opposite.

  Note that the first input operation or the second input operation may be performed on each of the plurality of determination areas 61. In this case, the game control unit 57 may perform different game progressions by combining the first input operation and the second input operation. For example, in the example of FIG. 4, the first input operation may be performed on both of the two non-player characters C1 and C2. In this case, the game control unit 57 may advance two events in the order in which the first input operation is performed. For example, when the first input operation is performed on the non player character C2 after performing the first input operation on the non player character C1, an event to go to shopping is first executed, and then a park is performed. Going event is executed.

  Further, for example, in the case where the first input operation is performed on one of the two non-player characters C1 and C2 and the second input operation is performed on the other, the game control unit 57 performs any input operation. Different game progress may be performed depending on whether it is performed first. For example, when a second input operation is performed on a non player character C2 after performing a first input operation on the non player character C1, an event to go shopping with the non player character C1 is executed, and this event A non-player character C2 may be attached to the event (3 persons may go to shopping). On the other hand, for example, when the first input operation is performed on the non-player character C1 after the second input operation is performed on the non-player character C2, the non-player character C2 is returned first, and the non-player character C2 is not An event in which the character C1 and two people go shopping may be executed.

  According to the above aspect, the virtual determination area 61 is set at a predetermined position in the space where the user U can view through the HMD 40, and the input operation is performed by crossing the virtual line of sight (intersection point P) of the user U into the determination area 61. Determination is made. Therefore, in the game executed by the game system using the HMD 40, an intuitive input operation can be performed while suppressing an erroneous operation. Furthermore, according to the above aspect, since the position P of the virtual line of sight is associated with the determination area 61, it is detected with high accuracy whether it is an input operation (for a question or the like) associated with the determination area 61. be able to. For this reason, the user U's unintended erroneous operation can be prevented. Further, as shown in FIG. 4, even when a plurality of determination areas 61 are displayed simultaneously, such swing movement input can be performed, so intuitive operation can be performed for more complicated input operations. it can. Therefore, it is possible to prevent the sense of immersion in the game from being disturbed by the time of the input operation.

  Further, in the present embodiment, as described above, when the user U performs the operation of shaking the head up and down, the first input operation is performed, and the user U performs the operation of shaking the neck left and right. Thus, the second input operation is performed. Therefore, two intuitive operations can be easily realized. Furthermore, in the determination of these input operations, the condition that the position P of the virtual line of sight of the user U continuously intersects the upper and lower limit border lines 61U and 61D of the determination area 61 or the left and right limit border lines 61L and 61R. By doing this, erroneous operation can be reliably prevented.

  As shown in FIG. 4, the determination area 61 may or may not be actually displayed on the game screen G. Instead of displaying the determination area 61 itself, a mark indicating that the determination area 61 has been set may be displayed on the object for which the determination area 61 is set. Further, after setting of the determination area 61 or after the acceptance of the answer input is started, the determination area setting means 52 displays the determination area 61 on the game screen G when an appropriate input operation is not performed even after a predetermined period. You may

  The area of the determination area 61 may change. For example, after the setting of the determination area 61 or after the reception of the answer input is started, the determination area setting unit 52 may enlarge the determination area 61 if an appropriate input operation is not performed even after a predetermined period. .

[Game interruption processing]
In the present embodiment, game interruption objects K are arranged in the virtual space S at predetermined intervals. The determination area 61 is also set near the game interruption object K. The game interruption object K has, for example, a shape resembling a first aid kit. When it is determined that the predetermined input operation has been performed on the determination area 61 set in the game interruption object K, the interruption process execution means 56 interrupts the game being executed.

  For example, the predetermined input operation may be the second input operation. In this case, when the user U wants to interrupt the game, the user U performs an operation of shaking his / her neck from side to side, thereby performing the process of interrupting the game.

  Thereby, an intuitive input operation can be performed as a command input to the game interruption object K. Therefore, when the user feels sick by using the HMD 40, the game can be used as an emergency stop operation for interrupting the game.

[Other examples]
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.

  For example, in the above embodiment, the first input operation is performed by the user U shaking his head up and down to perform the first input operation, and the second operation by the user U shaking the neck left and right. An example is shown where an input operation is performed. Additionally or alternatively, the motion may be detected as a plurality of input operations according to the angle (swing width) at which the user U swings his head or neck.

  For example, as the determination area, a second upper limit boundary and a second lower limit are set between the upper limit boundary 61U and the lower limit boundary 61D shown in FIG. 4, and the input operation determination means 53 When the position P alternately exceeds the upper limit boundary line 61U and the lower limit boundary line 61D, it is determined that the operation is based on the first swing width, and the virtual line-of-sight position P is the second upper limit boundary line and the second lower limit It may be determined that the operation is based on the second swing width when the boundary line is alternately crossed but the first upper boundary line or the second lower boundary line is not crossed. In this case, since the first swing width (when deeply peeping) and the second swing width (if shallowly peeping) are determined as different operations, the non player character is different depending on the difference in the depth of peeping. It is possible to realize such an aspect that reactions of C1 and C2 are different, or progress of events is different.

  Similarly, as the judgment area, the second left boundary and the second right boundary are set between the left boundary 61L and the right boundary 61R shown in FIG. Determines that the operation based on the first swing width is performed when the position P of the virtual line of sight alternately passes over the left limit line 61L and the right limit line 61R, and the virtual line of sight position P is the second left It is determined that the operation is based on the second swing width when the boundary and the second right boundary are alternately crossed but the first left boundary or the second right boundary is not crossed You may

  Furthermore, in addition to or instead of the swing width, the action may be detected as a plurality of input operations according to the speed at which the user U shakes his head or neck. For example, when the time from the position P of the virtual line of sight to the left boundary line 61L to the intersection of the right boundary line 61R is shorter than a predetermined threshold value, the input operation determination unit 53 determines the first velocity. It may be determined that the operation is based on the second speed when it is determined that the operation is based on the above and the predetermined threshold or more. In this case, since the first speed (if you shake your head fast) and the second speed (if you shake your head slowly) are determined as different operations, the non-player character C1 is different depending on the depth of the swing. , C2 reaction, or the progress of the event is different.

  When the determination area 61 is set near the face of the non player characters C1 and C2, the input operation determination means 53 moves the position P of the virtual line of sight up and down in the determination area 61 or an area including the determination area 61. It may be determined whether or not the user U is playing back (hearing a talk) on the conversation of the non-player characters C1 and C2 who are the talkers by judging whether or not the user U is a speaker. If it is determined that the user U has not heard the story, the game control means 57 changes the attitude of the non player characters C1 and C2 to stop the conversation of the non player characters C1 and C2 (for example, the mood worsens) Etc.), the contents of conversation may change, or the progress of an event may change. As a criterion for determination of the crawling operation, timing may be set that requires the crawling operation according to the content of the conversation, or it may be set that the crawling operation is necessary once every predetermined time.

  Further, an inclination (a difference in height between the pair of display portions 41 a and 41 b of the head mounted display 40) of the head of the head of the user U is detected from a gyro or the like built in the head mounted display 40 and input The operation determination means 53 may determine that the user U has a crouched neck when the inclination of the head of the user U about the front-rear direction axis is equal to or more than a predetermined angle. Thereby, it can be detected that the user U feels that it is difficult to answer or is lost. When it is determined that the user U has a crooked head when requesting an answer to the question from the user U, the game control means 57 changes the contents (options) of the question or progresses the event. It may be changed or the like.

  Further, the shape of the determination area 61 may be a polygon, a circle, or a line, as well as a rectangle as in the above embodiment. Further, in the above embodiment, the determination area 61 has a planar shape, but may have a three-dimensional shape. Further, the shape of the determination area 61 set according to the type of the object for which the determination area 61 is set may be different.

  Further, in the above embodiment, two input operations can be performed using one determination area 61. However, only one input operation may be performed, or three or more input operations may be performed. It may be possible.

  The hardware configuration according to the above-described embodiment is merely an example, and any configuration that can detect the movement of the head of the user U may be used. In addition, this aspect is applicable not only to a VR type game system but also to an AR type, SR type or MR type game system. Further, this aspect is also applicable to a configuration in which the display unit has only one HMD, such as an AR type game system, for example. In this case, the position P of the virtual line of sight may be a position at a predetermined distance of the extension from the predetermined position of the one display unit, or the extension direction of the extension may be infinity, and only the remaining two-dimensional coordinate position. The input operation determination may be performed in The determination area may be set to a predetermined object (a predetermined building or the like) in the real space, or may be set to a predetermined virtual object displayed in the information display area of the head mounted display 40.
