  • Patent number: 10620791
    Abstract: Icons 514a and 514b are disposed so as to cross a circumference 512 that is positioned around a head of a user 516 and in a horizontal plane including a line-of-sight vector prevailing when the user 516 faces forward in a virtual space. In this instance, icons 514a whose center is above the circumference 512 and icons 514b whose center is below the circumference 512 are alternately disposed. A menu screen is drawn by identifying a normal vector 517 of the face of the user as a line of sight in accordance with posture information related to the user's head, setting a screen 518 in a vertical plane around the line of sight, and projecting a virtual space object onto the screen 518.

  • Patent number: 10336609
    Abstract: First, an ion beam is applied to a workpiece to form a tapered hole the side wall of which is inclined. Next, the application of the ion beam is stopped, and then a material gas is introduced from the gas source to the upper surface of the workpiece from an oblique direction to cause gas molecules to be adsorbed to the upper surface of the workpiece and to the upper portion of the side wall of the hole. Next, introduction of the material gas is stopped, and then the ion beam is applied again to the region of the workpiece where the hole is formed. As a result, at the upper portion of the side wall of the hole, film formation occurs using the gas molecules as the material adsorbed to the side wall of the hole, and, at the bottom portion of the hole, etching of the workpiece occurs.
