Patent attributes
A Virtual Reality (VR) image generation system includes a sensor; a detection circuit which, in operation, detects a first indicated position indicated by an electronic pen in a first three-dimensional space in accordance with transfer of a signal between the electronic pen and the sensor; one or more processors; and one or more memory devices storing instructions that, when executed by the one or more processors, cause the one or more processors to: detect a first posture of the electronic pen in a second three-dimensional space, the first posture including at least one of a first inclination angle, a first inclination direction and a first rotation angle of the electronic pen, and generate, when the electronic pen is in the first three-dimensional space, a first VR image of drawing by the electronic pen, based on the first indicated position and the first posture.
