The character input device includes a base. An input unit is provided on the base and independently performs first directional input in which the input unit moves from a reference location to one of first direction indication locations arranged radially around the reference location and spaced apart from one another, and second directional input in which one of second direction indication locations arranged radially on the input unit and spaced apart from one another is selected. A first detection unit detects movement of the input unit. A second detection unit detects second directional input. A control unit extracts a first character assigned to a first direction indication location at which movement of the input unit is detected, or a second character assigned to a second direction indication location at which second directional input is detected."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Character input device","description":"The present invention relates to a character input device.
