  According to the above configuration, the target object displayed on the display while the game is in progress is selected by the player's gaze, and the mission achievement is determined by the combination of the target objects whose display mode has been changed by the selection. While the game is in progress, the gaze position of the player is displayed in the virtual space shared by the two players, so when the gaze position of another player is included in the player's visual field range, the player It is possible to grasp the start of selection by or the target object being selected. In addition, since the display mode of the selected target object changes, the selected player himself and other players who have visually recognized the target object can grasp that the gaze is effective. For this reason, communication between players can be assisted in a game in which a plurality of players select objects in a virtual space.

  (2) About the said game processing program, it is preferable that the said gaze position display part displays the direction which goes to the said gaze position from the position of the said player in the said virtual space as a light ray. Thereby, when a light ray intersects within the visual field range of the player, the player can grasp the direction of the line of sight of another player.

  (3) About the said game processing program, it is preferable that the said display mode change part continues the state from which the display mode of the said target object changed after the display mode of the said target object changed. Thus, the player can intuitively understand that the selection of the target object is completed.

(First embodiment)
Hereinafter, a first embodiment will be described for a game processing program, a game processing device, and a game processing method. In a game provided to players by executing a game processing program in a game processing device, it is assumed that all players wear a head-mounted display (HMD) on their heads. In the present embodiment, a game in which two players progress in a team will be described, but any number of people may be included in the team.

  With reference to FIG. 1, a configuration of a system including the HMD 10 and the game processing device 20 will be described. First, the configuration of the HMD 10 connected to the game processing device 20 will be described. The HMD 10 includes an HMD control unit 11, a sensor 12 as a detection device, and an input / output interface unit (I / F unit) 13. The HMD control unit 11 outputs various information to the game processing device 20 and inputs various information from the game processing device 20 via the input / output I / F unit 13. The sensor 12 corresponds to a detection device for specifying the position and orientation of the player's head. The sensor 12 includes, for example, at least one of a gyro sensor, an acceleration sensor, a geomagnetic sensor, and the like, and detects the movement of the player's head. As another embodiment, a sensor that directly detects the movement of the eyeball of the player, for example, a line-of-sight detection sensor that detects near-infrared rays in the iris and detects the reflected light may be used as the sensor 12. . Here, in this embodiment, the player's head corresponds to a predetermined part of the player's body of the present invention.

  The HMD 10 also includes a display 14 that displays an image and a speaker 15 that outputs sound. For example, the display 14 displays an image visually recognized by the left eye and an image visually recognized by the right eye with parallax. Thereby, the player can visually recognize a stereoscopic image with a sense of depth. The HMD control unit 11 displays an image corresponding to the image signal received from the game processing device 20 on the display 14 via the input / output I / F unit 13. The speaker 15 is a headphone or the like, and outputs sound effects, sounds explaining the progress of the game, and the like.

  Next, the configuration of the game processing device 20 will be described. The game processing device 20 includes a control unit 21, a storage unit 22, and an input / output unit 23. The control unit 21 includes hardware elements such as a CPU, a RAM, and a ROM. The control unit 21 includes a gaze position specifying unit 24, a game management unit 25, and a display control unit 26. In the present embodiment, the control unit 21 functions as a gaze position specifying unit 24, a game management unit 25, and a display control unit 26 by causing a hardware element to execute a game processing program. The control unit 21 corresponds to a spatial image display unit, a gaze position display unit, a display mode change unit, and a determination unit.

The storage unit 22 stores virtual space image information 27, target object information 28, object status information 29, gaze position information 30, and gaze time information 31.
The virtual space image information 27 is data for drawing an image of a background or an object in a virtual space shared by two players.

  The target object information 28 is information regarding a target object that is an object that can be selected by the player among objects displayed in the virtual space, and includes the coordinates of the target object. The target object is selected when the player keeps gazing for a predetermined time. Further, when the selection of the target object is completed, the display mode changes.

  The object status information 29 is information indicating the selection state of each target object, and in the present embodiment, includes “basic state” or “valid state” as the selection state. In this embodiment, the “basic state” is a state before selection, and the “valid state” is a state in which the selection is completed and the display mode is changed.

The gaze position information 30 is information indicating the gaze position of each player. In the present embodiment, coordinates indicating the gaze position specified in the virtual space are recorded for each player.
The gaze time information 31 is information relating to the time during which each player continues to gaze at the target object.

  The gaze position specifying unit 24 of the control unit 21 inputs a detection signal of the sensor 12 from the HMD control unit 11 of the HMD 10 attached to each player via the input / output unit 23. Further, the gaze position specifying unit 24 specifies the gaze position of the player using the input detection signal, and stores the specified gaze position in the storage unit 22.

  The game management unit 25 compares the coordinates of the gaze position information 30 with the positions of the objects included in the target object information 28, and determines whether or not the gaze position is on the target object. When the game management unit 25 determines that the gaze position is on the target object, the game management unit 25 measures a gaze time, which is a time during which the player keeps gazing at the target object, based on a system time using a CPU clock signal or the like. To do. Further, the game management unit 25 stores the measured gaze time in the storage unit 22 as gaze time information 31.

  Further, the game management unit 25 determines whether or not the gaze time has reached a predetermined time (for example, 3 seconds), and determines that the selection of the target object has been completed when the gaze time has reached the predetermined time. The game management unit 25 updates the object status information 29 of the target object that has been selected to the valid state.

  Further, the game management unit 25 determines whether or not the mission clear condition is satisfied within the time limit of the game based on the object situation information 29. Here, it is assumed that the mission clear condition includes a predetermined number of target objects having valid states set simultaneously. The game management unit 25 determines that the game is over when the elapsed time from the start of the game reaches the time limit without satisfying the mission clear condition.

  Further, the game management unit 25 extracts sound information such as sound effects and sound explaining the progress of the game from a sound information storage unit (not shown), and transmits the sound information to the HMD 10 via the input / output unit 23.

  The display control unit 26 specifies a visual field range in the virtual space centered on the gaze position indicated by the gaze position information 30 of each player, and extracts virtual space image information 27 corresponding to the visual field range. In addition, the display control unit 26 transmits the extracted virtual space image information 27 to the HMD 10 as an image signal.

  Further, the display control unit 26 displays the target object according to the object status information 29. When the object status information 29 includes the basic state as the selected state, the display control unit 26 sets the target object as a normal display. When the object status information 29 includes a valid state as a selected state, the display control unit 26 displays the target object in a valid state. As a result, the color, shape, and brightness of the target object change or a new display is added to the target object as compared with the display of the basic state.

Further, the display control unit 26 displays a character corresponding to the player in the virtual space for each player.
Next, a gaze position display function by the game processing device 20 will be described with reference to FIG. The gaze position specifying unit 24 receives the detection signal of the sensor 12 from the HMD 10 and specifies the position and orientation of the head of the player 101 according to the detection signal. Specifically, the gaze position specifying unit 24 determines the position and orientation of the head, the X axis along the horizontal direction and the pitch θp indicating the rotation direction around the X axis, the Y axis along the vertical direction, and the Y axis. The yaw θy indicating the rotation direction around the axis, the Z axis along the depth direction, and the roll θr indicating the rotation direction around the Z axis in the three-axis direction and the angle around each axis are calculated.

  The gaze position identifying unit 24 identifies the gaze position of the player 101 in the virtual space 100 based on the identified position and orientation of the head. As a method for specifying the gaze position, a known method corresponding to the type of the sensor 12 can be used. For example, the gaze position specifying unit 24 virtually sets a straight line connecting the left eye position and the right eye position, extends in a direction orthogonal to the straight line, and passes through the middle point of the left eye position and the right eye position as the gaze direction D1. And Furthermore, the gaze position specifying unit 24 specifies the intersection of the line-of-sight direction D1 and the object 102 (or background) as the gaze position P1. Note that when the sensor 12 detects the movement of the eyeball or detects the reflected light from within the iris, the line-of-sight direction is specified based on the movement of the eyeball or the reflected light.

  The display control unit 26 displays the light beam 103 traveling in the virtual space 100 toward the gaze position P1 on the virtual space image. In the present embodiment, the light beam 103 toward the gaze position P1 is displayed as a light beam emitted from the electric lamp 105 possessed by the character corresponding to the player. The light emission position of the electric lamp 105 can be set to a predetermined position and direction moved from the specified position and orientation of the head. Further, the display control unit 26 displays the specified gaze position P1 on the virtual space image as the irradiation position 104 where the light beam 103 is irradiated on the object 102 or the background.

  Since the virtual space is shared by the two players, when the irradiation position 104 indicating the gaze position of one player 101 is included in the visual field range of the other player 101, the display 14 of the latter player 101 is displayed. The irradiation position 104 of the former player 101 is displayed. As a result, the latter player can grasp the object viewed by the former player 101 in the virtual section.

  When the light beam 103 of one player 101 is included in the visual field range of the other player 101, the light beam 103 of the former player 101 is displayed on the display 14 of the latter player 101. Therefore, the latter player 101 can grasp where the line of sight of the former player 101 heads.

  Next, with reference to FIGS. 3 to 7, a processing procedure for each process for providing a game to the player will be described. In the present embodiment, each process will be described by exemplifying the mission clear condition of the game as “a pair of valid target objects exist simultaneously” within the time limit. It should be noted that objects other than the target object cannot be selected. In addition, a pair of objects must be selected by two players one by one. However, the mission clear conditions and the conditions for object selection are not limited to these, and can be changed as appropriate.

  When the game is started, the control unit 21 of the game processing device 20 calculates the position and orientation of the head according to the detection signal input from the sensor 12 of the HMD 10. Further, the control unit 21 specifies the gaze position based on the position and orientation of the head. Further, the control unit 21 extracts the virtual space image information 27 in the visual field range centering on the gaze position, and transmits the extracted virtual space image information 27 to the HMD control unit 11 as an image signal. The HMD control unit 11 outputs an image corresponding to the received image signal to the display 14. In this way, the game processing device 20 progresses the game while displaying the virtual space image corresponding to the position and orientation of the player's head on the display 14.

(Object selection process)
With reference to FIG. 3, the procedure of the object selection process will be described. This process is executed for each player. Further, the condition for ending this process is that either the mission is cleared or the elapsed time measured from the start of the game before the mission is cleared reaches the time limit. This process is repeated until the end condition is satisfied.

  When the game is started, the control unit 21 of the game processing device 20 specifies the gaze position of the player (step S1). Specifically, the gaze position specifying unit 24 of the control unit 21 calculates the position and orientation of the head according to the detection signal of the sensor 12. The gaze position specifying unit 24 specifies the gaze position of the player using the position and orientation of the head, and records the specified gaze position in the storage unit 22 as the gaze position information 30.

  Next, the control unit 21 of the game processing device 20 executes a determination process as to whether or not the gaze position is on a selectable object (step S2). Specifically, the game management unit 25 of the control unit 21 compares the specified gaze position information 30 with the target object information 28. Here, when the gaze position included in the gaze position information 30 overlaps the position of the target object, it is determined that the gaze position is on a selectable object.

  When it is determined that the gaze position information 30 is other than a selectable object (“NO” in step S2), the control unit 21 of the game processing device 20 sets the gaze time information 31 to “gaze time = 0” ( Step S7) and return to step S1.

  On the other hand, when it is determined that the gaze position information 30 is on a selectable object (in the case of “YES” in step S2), the control unit 21 of the game processing device 20 locks the selection of the target object, and gazes time. Is measured (step S3). Specifically, the game management unit 25 of the control unit 21 prohibits the selection of the target object by other players and measures the elapsed time from the start of gaze based on the system time and the like. In addition, the game management unit 25 records the measured elapsed time in the storage unit 22 as gaze time information 31.

  Next, the control unit 21 of the game processing device 20 displays a gauge indicating the lapse of the gaze time (step S4). Specifically, the display control unit 26 of the control unit 21 displays the gauge on the selected target object. The gauge corresponds to a gaze time display, and represents a lapse from a gaze start to a predetermined time.

  Next, the control part 21 of the game processing apparatus 20 performs the determination process about whether the gaze time reached predetermined time (step S5). Specifically, the game management unit 25 of the control unit 21 reads the gaze time information 31 from the storage unit 22 and determines whether or not the time indicated by the gaze time information 31 has reached a predetermined time.

  When it is determined that the gaze time has not reached the predetermined time (in the case of “NO” in step S5), the control unit 21 returns to step S1 and specifies the gaze position. The control unit 21 determines whether or not the gaze position is on a selectable object (step S2). Then, when it is determined that the gaze position information 30 is other than a selectable object (in the case of “NO” in step S2), that is, when the gaze is deflected from the target object before the gaze time reaches a predetermined time, The control unit 21 of the game processing device 20 sets the gaze time information 31 to “gaze time = 0” (step S7), resets the gaze time, and returns to step S1.

  On the other hand, if it is determined that the gaze time has reached the predetermined time (in the case of “YES” in step S5), the control unit 21 updates the object status information 29 of the target object (step S6).

  For example, if the basic state is recorded in the object situation information 29 immediately before step S6, the game management unit 25 of the control unit 21 updates the object situation information 29 to the valid state. If the valid state is recorded in the object situation information 29 immediately before step S6, the game management unit 25 updates the object situation information 29 to the basic state. Therefore, when an already selected object is selected again, the state returns to the basic state, and the mission is not cleared. After the object status information 29 is updated to the valid state, the process returns to step S1 while the game does not end.

(Object display processing)
Next, with reference to FIG. 4, the procedure for the display processing of the selected object will be described. The end condition of this process is that either the mission is cleared or the elapsed time reaches the time limit, and this process is repeated until the end condition is satisfied.

  First, the control unit 21 of the game processing device 20 acquires the object status information 29 of the target object (step S10). Specifically, the game management unit 25 of the control unit 21 reads one object status information 29 from the storage unit 22 according to a predetermined order.

  Next, the control part 21 of the game processing apparatus 20 displays a target object according to the object status information 29 (step S11). Specifically, when the object status information 29 is in the basic state, the target object is in the basic state display mode, and when the object status information 29 is in the valid state, the target state is in the valid state display mode. The control unit 21 repeats this procedure for all target objects. When the change process is completed for all the target objects, if the elapsed time from the start of the game is within the time limit, the change process is repeated from the first target object.

(Game progress process)
Next, the game progress process will be described with reference to FIG. First, when the game is started, the control unit 21 of the game processing device 20 measures an elapsed time from the start of the game (step S20). Specifically, the game management unit 25 of the control unit 21 measures the elapsed time based on the system time.

  Next, the control unit 21 of the game processing device 20 determines whether or not the elapsed time is a time limit (step S21). If it is determined that the elapsed time has exceeded the time limit (in the case of “NO” in step S21), the control unit 21 of the game processing device 20 ends the game (step S25).

  On the other hand, when it is determined that the elapsed time is within the time limit (in the case of “YES” in step S21), the control unit 21 of the game processing device 20 acquires the object situation information 29 from the storage unit 22 (step S22). . Specifically, the game management unit 25 reads out object status information 29 of all target objects from the storage unit 22.

  And the control part 21 of the game processing apparatus 20 judges whether there exists a combination of the display state used as mission clear (step S23). More specifically, the game management unit 25 of the control unit 21 determines whether there is a combination of valid target objects that are mission clear conditions, based on the acquired object status information 29. In the present embodiment, it is determined whether or not there is a pair of target objects whose valid states are recorded in the object status information 29.

  When it is determined that there is a combination of display states that will clear the mission (in the case of “YES” in step S23), the control unit 21 of the game processing device 20 determines that the mission is cleared (step S24) and ends the game. (Step S25). Specifically, the game management unit 25 of the control unit 21 determines that the mission is cleared when there is a pair of target objects whose valid states are recorded in the object status information 29.

  On the other hand, when it is determined that there is no combination of display states for mission clear (in the case of “NO” in step S23), the control unit 21 of the game processing device 20 returns to step S20 and measures the elapsed time. Specifically, the game management unit 25 of the control unit 21 determines that the mission is not cleared when there is only one target object whose valid state is recorded in the object status information 29 or when there is no target object. Then, the process returns to step S20.

  With reference to FIG.6 and FIG.7, the image displayed on the display 14 of HMD10 during game progress is demonstrated. Note that the virtual space images shown in FIGS. 6 and 7 are schematically shown regardless of the field of view range of the HMD 10.

  As shown in FIG. 6, the control unit 21 of the game processing device 20 displays a virtual space image 200 with the gaze position of the player at the center of the visual field range on the display 14. As an example, a plurality of cylinders 201 are displayed in the virtual space image 200 as one of the target objects. In addition, among the objects, the target object and other objects may be made identifiable, for example, a target object that is a selectable object is illuminated.

  The gaze position of each player is displayed as the irradiation position 104 where the object or background is irradiated with light. Further, the direction from the character position corresponding to the player toward the irradiation position 104 is displayed as a light beam 103 emitted from the electric lamp 105 of the character. In addition to the electric lamp 105, the hand of the character having the electric lamp 105 may be displayed. Further, the electric lamp 105 may not be displayed in the virtual space image.

  The cylinder 201 is an object that operates on display when transitioning from the basic state to the valid state. In the basic state, it is displayed in a display mode divided into two. Moreover, the cylinder 201 is displayed in the connected display mode in the effective state. When the player gazes at the cylinder 201, an annular gauge 205 is displayed so as to overlap the cylinder 201 around the gaze position. At this time, the gauge 205 is disposed so that the gaze position specified by the control unit 21 is located at the center of the gauge 205. Therefore, the specified gaze position is not hidden by the gauge 205, and a part of the cylinder 201 that is the target object can be visually recognized. This makes it easier for the player to continue gazing at the cylinder 201 through the center of the gauge 205.

  In the gauge 205, the area 206 increases with the passage of time from the start of gaze. When the gaze time reaches a predetermined time, the gauge 205 is deleted. However, when the gaze time reaches a predetermined time, the state where the gauge 205 has reached the predetermined time may be maintained, or an icon indicating completion may be displayed.

  Furthermore, as shown in FIG. 6, when the gauge 205 displayed by the other player gazing at the column 201 is included in the player's visual field range, the gauge 205 by the other player is displayed. For this reason, it becomes easy to grasp what kind of situation each player has.

  As illustrated in FIG. 7, when the player continuously watches the column 201 for a predetermined time, the control unit 21 sets the display mode of the column 201 to an effective state. For example, in the example of the cylinder 201 described above, the upper part of the divided cylinder 201 is lowered toward the lower part, and the upper part and the lower part are connected. Thus, the player can intuitively understand that the selection of the target object has been completed by operating the cylinder 201 immediately after the measurement of the elapsed time by the gauge 205 is completed. If it is determined that there is a pair of cylinders 201 in which the upper part and the lower part are connected, the control unit 21 determines that the mission is clear.

  On the other hand, if the cylinder 201 in which the upper part and the lower part are connected is selected again by gaze, the upper part rises and separates from the lower part. When the upper part and the lower part of the cylinder 201 are disconnected, the control unit 21 updates the object status information 29 of the cylinder 201 to the basic state. For this reason, even if the cylinder 201 is once connected, the control unit 21 does not determine that the mission is cleared if the connection is released without the other connected cylinders 201 existing at the same time.

  As described above, in a game in which a target object is selected by gaze, the player's gaze position is indicated by the irradiation position 104 in the virtual space, and the display mode of the selected target object is changed to assist mutual understanding of the situation. can do. In addition, since the gaze position is expressed as the irradiation position where the light beam 103 emitted from the lamp 105 held by the character is irradiated to the object or the like, it is possible to prevent the sense of immersion in the virtual space from being impaired. Further, by assisting the grasping of the situation between the players in this way, even in the virtual reality game using the HMD 10, there are few obstacles for a plurality of players to cooperate and advance the game, stress that the player feels, etc. It can enhance the interest of the game.

  In addition, as a method of grasping the situation between players, for example, there is a method such as voice chat in which data voices are exchanged between the HMDs 10 of each player. However, this method may be part of communication assistance, but when the number of participants in the game becomes 3 or more, it becomes difficult to associate voice chat voices with characters in the virtual space, and to grasp the situation of each person Is not easy. In the above-described game, the gaze position of each player is displayed as the irradiation position 104, and the display mode of the selected target object is changed. Therefore, even when the number of players increases to three or more, it is easy to grasp the situation of each player can do.

As described above, according to the first embodiment, the effects listed below can be obtained.
(1) In the first embodiment, the gaze position of the player is displayed as the irradiation position 104 in the image of the virtual space shared by the two players. Thereby, when the gaze position of another player is included in the player's visual field range, the player can grasp a target object that is being selected or started by another player. Further, since the display mode of the selected target object changes, the selected player himself and other players who have visually recognized the target object can grasp that the gaze is effective. Therefore, it is possible to assist in grasping the situation of each player in a game in which a plurality of players select an object in the virtual space.

  (2) In the first embodiment, the light beam 103 from the position in the player's virtual space to the gaze position is displayed in the virtual space image. For this reason, when the light beam 103 of another player crosses within the player's visual field range, the player can grasp the destination of the other player's line of sight.

  (3) In the first embodiment, after the display mode of the target object is changed, the state in which the display mode is changed is maintained even when the player's line of sight deviates from the target object. For this reason, the player can intuitively understand that the selection of the target object is completed.

  (4) In the first embodiment, the gauge 205 is displayed when the gaze of the target object by the player is specified, and the time during which the gaze is continued is expressed. Therefore, the player can grasp that the gaze is effective, and can intuitively grasp that the gaze is necessary until the gaze time reaches a predetermined time.

(Second Embodiment)
Next, a second embodiment that embodies a game processing program, a game processing device, and a game processing method will be described. Since the second embodiment has a configuration in which part of the object selection process of the first embodiment is changed, the same parts are denoted by the same reference numerals and detailed description thereof is omitted.

  The game of the present embodiment is the same as that of the first embodiment in that the mission is cleared when there is a pair of target objects that have transitioned to the valid state at the same time within the time limit. However, in the present embodiment, it is assumed that the target objects that change to the valid state include only one pair that is the same as the number of players in the selectable target objects. In other words, the target objects include those that transition to the valid state and those that do not transition to the valid state. Also, in selecting the target object, the selection is canceled unless the target object is continuously watched. Therefore, two players need to select one pair of objects one by one.

  Either “basic state” or “valid state” is set in the object status information 29 of the target object transitioning to the valid state. For the target object that does not transition to the valid state, either the “basic state” or the “change state” in which the display mode is changed by the player's gaze but does not satisfy the mission clear condition is set. . Information indicating that the target object is a target object that transitions to the “valid state” or an object that transitions to the “change state” is included in the target object information 28.

  With reference to FIG. 8, the procedure of the object selection process executed for each player will be described. The end condition of this process is that either the mission has been cleared or that the elapsed time measured from the start of the game before reaching the mission has reached the time limit has been established. Repeat until the end condition is met.

  As in the first embodiment, the control unit 21 of the game processing device 20 performs a gaze position specifying process (step S1) to a determination process (step S5) as to whether or not the gaze time has reached a predetermined time. Further, the control unit 21 resets the gaze time to “0” when the gaze position deviates from the target object before the gaze time reaches the predetermined time (step S7).

  When it is determined in step S5 that the gaze time has reached the predetermined time (in the case of “YES” in step S5), the control unit 21 of the game processing device 20 changes the target object to the valid state based on the target object information 28. The type is determined as to whether or not to change to a change state (step S10).

  And the control part 21 of the game processing apparatus 20 sets the object status information 29 based on the kind of object object (step S11). For example, when the target object transitions to the valid state, the game management unit 25 of the control unit 21 updates the object situation information 29 from the basic state to the valid state. When the target object transitions to the change state, the game management unit 25 updates the object situation information 29 from the basic state to the change state.

  In addition, the game management unit 25 records the valid state in the object status information 29 for the target object that can transition to the valid state. For the target object that transitions to the change state, the game management unit 25 records the change state in the object status information 29.

  Next, the control unit 21 of the game processing device 20 determines whether or not the object gaze is continued (step S12). Specifically, the game management unit 25 of the control unit 21 determines whether or not the gaze position is on the target object based on the gaze position information 30 and the target object information 28.

  When it is determined that the object gaze is continued (in the case of “YES” in step S12), the control unit 21 of the game processing device 20 uses the object status information 29 based on the type of the target object as “valid state” or “ “Change state” is maintained (step S11).

  On the other hand, when it is determined that the gaze of the object is not continued (in the case of “NO” in step S12), the control unit 21 of the game processing device 20 sets the object state to the basic state (step S12), and step S1. Return to.

  Also in the present embodiment, the procedure for the display process of the selected object and the game progress process is the same as in the first embodiment. However, in the display processing of the present embodiment, in the object display (step S11), when the object status information 29 is in the changed state, the changed state is displayed, and when the object state information 29 is in the enabled state, the active state is displayed. This is different from the first embodiment. Then, the control unit 21 determines that the mission is cleared when the pair of target objects become valid.

  Next, an image displayed on the display 14 of the HMD 10 while the game is in progress will be described with reference to FIGS. 9 and 10. Note that the virtual space images shown in FIGS. 9 and 10 are schematically shown regardless of the visual field range of the HMD 10.

  As shown in FIG. 9, an object such as a cylinder 201 is displayed on the display 14. Among the objects, there are a plurality of target objects that can be selected by the player. As the target object is selected by the player, the display mode of each of the target objects changes. When the cylinder 201 which is the target object is selected by gaze, a gauge 205 is displayed. The gaze position of each player is displayed as the irradiation position 104, and the direction from the player position in the virtual space toward the irradiation position 104 is displayed as the light beam 103.

  As shown in FIG. 10, a light beam 210 emitted from the cylinder 201 is displayed on the cylinder 201 that has transitioned to the effective state. The light ray 210 is displayed on the display 14 of the player whose optical path is included in the visual field range.

  As shown on the left side in FIG. 10, when the cylinder 201 that has transitioned to the change state is selected, a light beam 211 in a direction different from the light beam 210 is displayed. The cylinder 201 that has transitioned to the change state may display a different color or number of light rays from the effective state in addition to the light ray 211 in a direction different from the effective state, or may simply change the color. . In order to clear the mission, it is not essential that the emission of the light beam 210 is started at the same time, and the light beam 210 is emitted from the pair of cylinders 201 by maintaining the state in which the light beam 210 is emitted. It is judged that the mission is cleared when it is in the state.

  Thus, it is possible to grasp that the target object is an object for mission clearing only after the display mode of the target object is changed by gaze. Therefore, the player must select an arbitrary target object in cooperation with other players and search for a target object that is in an effective state. Therefore, the player needs to cooperate not only in selecting a target object at the same time but also in a task of searching for a predetermined target object. For this reason, the interest of the virtual reality game played by a plurality of people can be improved. In addition, since the synchronism is also required in selecting the target object to be transitioned to the valid state, the interest of the game can be improved in this respect.

As described above, according to the second embodiment, in addition to the effects described in the first embodiment, the effects listed below can be obtained.
(5) In the second embodiment, the state in which the display mode of the target object is changed to the valid state is maintained on condition that the player continues to watch. For this reason, in order to clear the mission, simultaneity is required for the player to select the target object. For this reason, the interest about implement | achieving mission clear can be raised.

In addition, each said embodiment can also be suitably changed and implemented as follows.
In the first embodiment, all target objects can be changed from the basic state to the valid state for the target object. In the second embodiment, it is assumed that two of the same number of target objects as the number of players can transition from the basic state to the valid state. For the target object. It is not limited to these.

  For example, a predetermined number of target objects that are a part of all target objects and are larger than the number of players may be able to transition from the basic state to the valid state. The ease of mission clearing can be adjusted by adjusting the number of target objects that can transition to the valid state according to the content of the game.

  In the first embodiment, the mission clear condition is selected by gazing at the target object for a predetermined time to be in the valid state, and the mission is cleared when there is a pair of valid target objects at the same time. The mission clear conditions are not limited to these aspects. For example, the mission may be cleared when a pair of valid target objects exist at different timings within the time limit from the start of the game.

  Further, the number of target objects selected by the player as a mission clearing condition is not limited to one for each player. For example, the target object may be mission cleared by each player selecting a plurality of target objects, or may be mission cleared by selecting a predetermined number of target objects for the entire team. Alternatively, in a competitive game or the like, target objects may be selected as much as possible within the time limit, and the winners may be competed according to the number of selected target objects.

  As for the mission clearing condition, all the players making up the team may make a mission clear by selecting the same object at the same time, or may make a mission clear by alternately selecting the same object or different objects.

  In each of the above embodiments, the gauge is displayed when the gaze position of the player is positioned on the target object. Instead of this, the gauge 205 indicating the gazing time may be displayed from the start of the game to the end of the game without the player gazing. In this case, the player can easily identify the target object and other objects. In this aspect, the gauge 205 may be displayed in a small size when the player is not gazing at the target object, and the gauge 205 may be enlarged when the player is gazing at the target object.

  In each of the above embodiments, the gaze position is displayed as the irradiation position 104 that is the position where the light beam 103 is irradiated on the object or the like. In addition to this, when the player is gazing at the target object, the control unit 21 of the game processing device 20 radiates light (brightness change) in a wide range so as to enter the field of view of other players. ) Or sound. According to this, it is possible to grasp that the teammate has selected the object even for the player whose gauge does not enter the field of view.

  In each of the above embodiments, the direction from the position of the player in the virtual space toward the irradiation position 104 is expressed by the light beam 103 emitted from the electric lamp 105. In addition to this, the light beam 103 may be a light beam other than the electric lamp 105 as a light source. For example, it may be displayed as a light beam emitted from an item other than the electric light possessed by the character, or may be expressed as a light beam emitted from at least one of the left eye and right eye of the player.

In each of the above embodiments, the player's gaze position is indicated as the irradiation position 104. In addition, the gaze position of the player may be indicated by a mark such as an arrow or a cross.
In each of the above embodiments, an annular gauge is displayed. Instead of this, a bar gauge or a flat gauge may be displayed. Alternatively, the gauge does not necessarily have to be displayed with a mark or the like, and may be a display change such as a change in brightness of the target object or a fade-out of the target object.

  In each of the above embodiments, the gauge indicating the gaze of the former player is displayed only when the gaze position that the other player gazes is included in the field of view of one player. Alternatively, if the visual field of one player does not include the target object or gauge 205 that the other player is gazing at, the object or gauge 205 is converted into an image of a virtual space that is visually recognized by the former player. It may be displayed on the sub screen to be overlaid.

  In each of the above embodiments, the case where a game played by two players is described has been described, but a game played by three or more players may be provided. In this case, the same number of HMDs 10 as the number of players are connected to the game processing device 20.

  In each of the above embodiments, the game processing device 20 specifies the position and orientation of the player's head. Instead of this, the HMD control unit 11 may calculate the position and orientation of the head based on the detection signal of the sensor 12. As described above, it is also possible to give the HMD 10 a part of the functions of the game processing device 20 described in the above embodiments.

  In each of the above embodiments, the system for specifying the gaze position of the player is embodied as a system that calculates based on the head position of the player, but may be a system that specifies the gaze position by other methods. For example, the gaze direction may be calculated based on the position and orientation of the pupil, and the gaze position may be specified from the gaze direction. Further, for example, the gaze direction may be calculated based on the position and direction of the nose or the position and direction of the mouth, and the gaze position may be specified from the gaze direction. Note that the direction of the nose and mouth may be determined as a direction from the back of the head toward the nose or mouth, for example.

  In each of the above embodiments, the plurality of players see the object in the virtual space from the viewpoint of the character corresponding to each player (character viewpoint), but each player may be switched in viewpoint. For example, each player may be able to select not only a character viewpoint but also an object in a virtual space from an overhead viewpoint from behind the player character. At this time, for example, each player may select the viewpoint before the game starts, or the viewpoint may be changed during the game. The player can easily grasp the position of the other player by selecting his / her favorite viewpoint, and can further cooperate with the other player.
