Image generation device, image display system, and information presentation method

An image display system comprising:

• an image generation device including circuitry configured to
• construct a virtual world to be displayed on a head-mounted display;
• generate, based on a position and a posture of a head of a player wearing the head-mounted display, a display image representing the virtual world in a field of view corresponding to a point of view of the player, and cause the head-mounted display to display the generated display image;
• acquire information regarding presence of an obstacle which is not related to the player in a space where the player is able to move;
• cause the head-mounted display to display an object in the virtual world corresponding to the obstacle while the obstacle is present in the space;
• the head-mounted display that displays an image output by the circuitry;
• and
• a sensor located at a fixed position that detects the obstacle and transmits data on the obstacle to the circuitry.

• acquire information regarding presence of an obstacle which is not related to the player in a space where the player is able to move;
• cause the head-mounted display to display an object in the virtual world corresponding to the obstacle while the obstacle is present;
• detect the obstacle's entry into and exit from a stay area preset in the space, wherein the stay area is a sub-area of the space represented in the virtual space at a corresponding location;
• and
• cause the head-mounted display to display an object surrounding a region corresponding to the stay area as the object indicating the presence of the obstacle while the obstacle is present in the stay area;
• the head-mounted display configured to display an image outputted from the image generation device;
• and
• an electronic device configured to input an operation indicative of the obstacle's entry into and exit from the stay area, and transmit information regarding the obstacle's entry into and exit from the stay area to the circuitry.

An information presentation method of an image generation device, comprising:

• constructing a virtual world to be displayed on a head-mounted display;
• generating, based on a position and a posture of a head of a player wearing the head-mounted display, a display image representing the virtual world in a field of view corresponding to a point of view of the player, and causing the head-mounted display to display the generated display image;
• acquiring information regarding presence of an obstacle which is not related to the player in a space where the player is able to move;
• and
• cause the head-mounted display to display an object in the virtual world corresponding indicating the presence of the obstacle while the obstacle is present within the area.

A non-transitory computer readable storage medium having stored thereon a program for causing an image generation device execute processing comprising:

• constructing a virtual world to be displayed on a head-mounted display;
• generating, based on a position and a posture of a head of a player wearing the head-mounted display, a display image representing the virtual world in a field of view corresponding to a point of view of the player, and causing the head-mounted display to display the generated display image;
• acquiring information regarding presence of an obstacle which is not related to the player in a space where the player is located;
• and
• causing the head-mounted display to display a first object in the virtual world corresponding to the obstacle while the obstacle is present within the space.
