Publication number: 20240394995Abstract: A virtual space presentation device includes a virtual space generation unit generating a virtual space including a virtual viewpoint of a user inside to allocate a content into the virtual space, a display control unit displaying the virtual space on a display unit, a detection unit detecting an action of the user, a virtual space correction unit moving the virtual viewpoint to correct the virtual space, and a display correction unit displaying the corrected virtual space on the display unit. The virtual space correction unit computes a display magnification on the basis of the virtual viewpoint, a first size applied to the content in a case where the virtual viewpoint is positioned at the center of the virtual space, and a second size different from the first size, and allocates the content to which a size according to the computed display magnification is applied to the corrected virtual space.Type: ApplicationFiled: August 24, 2022Publication date: November 28, 2024Applicant: NTT DOCOMO, INC.Inventors: Reo MIZUTA, Yasuo MORINAGA, Tatsuya NISHIZAKI, Mitsuhiro GOTO, Yuki NAKAMURA

Publication number: 20240127726Abstract: A display control device for performing control on a display of a display configured to display an image of content laid out in a virtual space as viewed from a predetermined position, the display being mounted on portions of eyes by a user. The device detects an orientation, with respect to the display, of a head portion of a person other than the user and determines whether a position of the content needs to be changed based on a detection-result and the position of the content in the virtual space. A position change destination of the content in the virtual space is set based on a distance between the position change destination of the content in the virtual space and a position at a current point in time of the content and to change the position of the content when the position of the content is to be changed.Type: ApplicationFiled: February 22, 2022Publication date: April 18, 2024Applicant: NTT DOCOMO, INC.Inventors: Yasuo MORINAGA, Nozomi MATSUMOTO, Hiroyuki FUJINO, Tatsuya NISHIZAKI, Reo MIZUTA, Yuki NAKAMURA
