  • Patent number: 12039898
    Abstract: In AR glasses, an incident angle calculation unit calculates first and second angles of incidence of first and second markers, respectively, to an imager relative to a reference line in the real world in accordance with image plane coordinates of the first and second markers in the image captured by the imager. A separation distance calculation unit calculates a camera-to-marker distance, which is a distance from the imager to the first marker, in accordance with the calculated first and second angles of incidence, and an inter-marker separation distance between the first and second markers along the reference line in the real world. A display adjustment unit adjusts a projection position and size of the AR image with respect to the first marker in the image plane coordinates in accordance with the camera-to-marker distance.

  • Publication number: 20240226856
    Abstract: Provided are: a carbon dioxide processing agent capable of fixing and decomposing carbon dioxide without the need for a heat treatment; and a method of producing a carbon dioxide processing agent, by which a carbon dioxide processing agent containing an oxygen-deficient magnetite can be produced without the need for a heat treatment in a hydrogen gas atmosphere. The carbon dioxide processing agent contains a magnesium oxide, an oxygen-deficient magnetite, and a zeolite. The method of producing a carbon dioxide processing agent includes the steps of: mixing and stirring a magnetite and a zeolite to obtain a mixed powder in which pores of the zeolite are filled with the magnetite; adding water to the mixed powder to obtain a mixture; and adhering a fine powder of magnesium oxide to the mixture and drying the resultant.
