  • Patent number: 11226689
    Abstract: A display system includes a display device, and an input device. The input device operates the display device, having a movement detection unit that include a sensor which detects a first movement that is circumferential around an axis and a second movement that is perpendicular the axis. The display device includes a first area in which characters are arranged and second area in which character string is displayed. A character that configures of the character string is selected from the first area according to the first movement and the second movement.
