Publication number: 20240020470Abstract: The character input device includes a character input section, a candidate obtainment unit, a finalization unit, and a registration unit. A character string is input to the character input section. The candidate obtainment unit obtains a candidate character string registered in the dictionary and corresponding to the character string that has been received by the character input section. The finalization unit finalizes the candidate character string obtained by the candidate obtainment unit and selected, as a finalized character string for the character string that has been received by the character input section. If a part of the finalized character string finalized by the finalization unit is deleted, the registration unit registers, in the dictionary, the remaining character string that remains without being deleted, in association with the character string that has been received by the character input section.Type: ApplicationFiled: February 24, 2023Publication date: January 18, 2024Applicant: OMRON CorporationInventor: Atsuhiro NAKAGAWA
