Abstract: A simulation system includes a processor including hardware. The processor performs: a virtual space setting process of setting a virtual space in which a plurality of objects are arranged; a virtual camera control process of controlling a virtual camera corresponding to a point-of-view of a user wearing a head mounted display; and a display process of generating an image as viewed from the virtual camera in the virtual space as a display image on the head mounted display. In the virtual space setting process, the processor arranges at least one information display object in a line-of-sight direction of the user, and in the display process, when it is determined that a given change condition is satisfied by a change in the point-of-view of the user, the processor performs a change process of a display mode of the information display object.

Abstract: A simulation control device includes: a display processing section; a measurement section that measures a gaze time of a user with respect to an object that is placed in the virtual space, and decreases a measured value obtained by the measurement corresponding to a time in which the user does not gaze at the object when the user has removed his/her gaze from the object; and a reception section that determines that the object has been selected when the measured value has reached a first threshold value, determines that the selection of the object has been confirmed when the measured value has reached a second threshold value that is larger than the first threshold value, and determines that the selection of the object has been canceled when the measured value has decreased to a third threshold value before the selection of the object is confirmed.

In the virtual space setting process, the processor arranges at least one information display object controlled to follow a change in the point-of-view of the user in the virtual space. In the display process, when the information display object and an object in the virtual space have entered into a given positional relationship, the processor performs a change process of a display mode of the information display object or the object.

Abstract: In a virtual reality space, a virtual reference body controlled to follow a player's hand, a virtual body part controlled to follow the player's ear, and a virtual smartphone being a virtual object as a prop are arranged. After the proximity of the virtual reference body to the virtual smartphone, the virtual smartphone is deemed as being gripped and the virtual reference body and the virtual smartphone are integrally moved. Stereophonic sound control is performed such that the emitted sound from the virtual smartphone is a ringtone before the proximity of the virtual reference body or the virtual smartphone to the virtual body part, and after the proximity, the emitted sound is switched to communication sound so that the player listens to the stereophonic sound by a headphone.

Abstract: A gaze determination area is provided to an image displayed on a VR-HMD. An object that has been displayed within the gaze determination area for a time equal to or longer than a given time is determined to be a gaze object (cup object). First-level menu display objects that respectively represent first-level menu items among menu items having a hierarchical structure that are set to the object are displayed in an array in a reference direction that is defined with respect to the gaze object. When the user has turned his/her head so that the desired first-level menu display object is displayed within the gaze determination area, and the desired first-level menu display object has been detected to be the gaze object, the first-level menu item is selected, and second-level menu display objects that are lower than the selected first-level menu item are displayed.

Abstract: An image generation device includes a processor including hardware. The processor is configured to implement a reception process that receives a command selected by a player from a plurality of commands, a game process that includes a process that implements the effect of the received command, and a display process that displays a game image based on the results of the game process. The processor is configured to implement the game process that includes a process that implements the effect of the command that corresponds to information about a character that is the target of game play performed by the player and viewpoint information about the player.

Abstract: A game system includes a game processing section that performs a game process, a lottery processing section that sets a lottery range that specifies a range of items among a plurality of items used during the game process that are subjected to a lottery process, and selects an item from the items that belong to the lottery range by performing the lottery process, and an item acquisition processing section that performs a process that allows a player to acquire the selected item. Information about the plurality of items has a data structure in which the plurality of items are linked to have a parent-child relationship. The lottery processing section sets the lottery range so that a child item is included within the lottery range when a parent item has been set to an acquired state or an acquirable state, and changes the set lottery range based on given information.

Abstract: A game system includes a game processing section that performs a process that implements a game, a data link processing section that determines that a data link activation condition has been satisfied when a data link start positional relationship has been established between a moving object and another moving object, and performs a process that produces a data link effect that changes at least one of the radar-related capability of the moving object and the performance of the moving object, and a display processing section that performs a display process that displays a display object that notifies a player of information about a data link. The data link processing section performs a process that prohibits production of the data link effect during at least one of a given first period after the game has started, and a given second period after production of the data link effect has been canceled.
