Abstract: A communication load is reduced in a virtual-reality-space sharing system. An image generation device for generating a virtual reality space image includes a memory for storing an instruction and a processor coupled to the memory for executing the instruction. The instruction, when executed by the processor, causes the processor to acquire, from a second terminal sharing a virtual reality space with a first terminal used by a first user, line-of-sight information including a position and a line-of-sight direction of a second user using the second terminal in the virtual reality space, generate a virtual reality space image to be displayed on the first terminal based on the line-of-sight information acquired from the second terminal, and supply the generated virtual reality space image to the first terminal.

Abstract: In a method involving determining a point of gaze based on an actual line of sight and displaying a cursor or a pointer at that place to designate a position in a virtual space, the following problem has occurred. When it is considered that a normal line of sight is in a direction of slightly looking downward, it is not easy to designate a position on an object that does not always have a large apparent area as viewed from the operator side, like an upper surface or a lower surface of the object. A provisional line of sight for designating the object being a target of operation is output not from a position of an eye of the operator in the virtual space but from a position separated from the position of the eye by a certain first distance in an up-down direction.
