Abstract: Provided is a position input apparatus having a body portion and an extension portion. The body portion includes a body portion side surface with a thickness in a direction, and a screw hole provided on the body portion side surface, the extension portion includes a screw having a shaft provided with a screw thread corresponding to the screw hole and a head with a thickness in a center axis direction of the shaft, the screw is provided from inside of the extension portion such that the shaft protrudes outside from an extension portion side surface, and a head side surface of the screw is exposed to an upper surface side of the extension portion and is rotatable by a user, and the extension portion is attachable to the body portion by the screw being screwed to the screw hole on the body portion side surface.

Abstract: According to one aspect, it becomes possible to easily modify a 3D object which is displayed in a virtual reality space. A method is performed by a computer configured to be communicable with a position detection device that includes a drawing surface and that, in operation, detects a position of an electronic pen on the drawing surface. The method includes rendering, in a virtual reality space, a first object that is a 3D object, rendering, near the first object, a display surface that is a 3D object, rendering, on the display surface, a 3D line that is a 3D object generated based on the position of the electronic pen on the drawing surface, wherein the position of the electronic pen is detected by the position detection device, and outputting the first object, the display surface, and the 3D line, which are the 3D objects, to a display.

Abstract: Provided is an electronic pen including an electronic pen main body unit having a pen shape, and having a pen tip that, in operation, performs a position indication, the pen tip being formed in an end portion on a first end side of the electronic pen main body unit in an axial direction of the electronic pen main body unit, a weight member, and an attachment portion that detachably attaches to the weight member, the attachment portion being formed in an end portion on a second end side of the electronic pen main body unit in the axial direction of the electronic pen main body unit.

Abstract: To provide a controller that can reduce a sense of discomfort felt by a user. A pen-type controller with a grip according to the present disclosure includes a pen part that is formed in a pen shape, a grip part that intersects an axial direction of the pen part, and a battery that is arranged in the grip part.

Abstract: A coordinate input device is capable of enabling efficient input work by configuring an operation part so as to be operable by a hand opposite to a hand holding an indicator. The coordinate input device includes a position detection sensor which, in operation, detects a position indicated by an indicator, a casing including a rear surface and housing the position detection sensor, the rear surface facing an input surface, the input surface being a surface on which an input operation for inputting the position indicated by the indicator is performed and corresponding to a position detection region of the position detection sensor, and at least one grip part disposed on the rear surface of the casing are included. The at least one grip part includes a projecting portion that projects in a direction intersecting the rear surface and one or more operation parts are disposed on the projecting portion.
