  • Patent number: 11934592
    Abstract: A position indicator that indicates a position is disclosed. The position indicator includes a casing of an electronic pen, a position indicating part, a tracker, and a grip part configured to be gripped by a user. The position indicating part is disposed at one end of the casing. The position indicating part, in operation, indicates the position. The tracker, in operation, causes an external device to detect the position in a three-dimensional space. The grip part is orthogonal to the casing of the electronic pen.
