Patent number: 9552351Abstract: An information processing system for input prediction that displays written character string candidates of words or phrases corresponding to an input character string in a terminal device. The terminal device acquires internal candidates by performing a search based on the input character string and transmits a candidate transmission request signal including identification information of a terminal dictionary stored in the terminal device and the input character string to a server. The server performs a search through the terminal dictionary corresponding to the identification information in the received signal and through a server dictionary dedicated to the server. From dictionary data extracted from the server dictionary, the server returns dictionary data of external candidates different from dictionary data extracted from the terminal dictionary as external candidates to the terminal device.Type: GrantFiled: February 9, 2015Date of Patent: January 24, 2017Assignee: OMRON CorporationInventors: Masaharu Ueda, Chihoka Moribe, Mayu Nakano, Takuya Nakayama

Patent number: 8307281Abstract: This invention easily realizes a process of changing the display order of the candidates according to various input states. In a character input device of a mobile telephone, a wide variety of attributes representing an input state are set, and a conversion dictionary in which the attributes are registered in dictionary data of a corresponding word is set. An adjustment value setting unit determines the input state at a relative time point according to the start of input of the read character or the confirmation of the candidate, and sets an adjustment value to each attribute according to the determination content. A priority adjustment unit adjusts the priority with the adjustment value set to the attribute of the candidate for the candidate set with an attribute of each candidate extracted from the conversion dictionary by the read character string.Type: GrantFiled: April 29, 2009Date of Patent: November 6, 2012Assignee: Omron CorporationInventors: Masaharu Ueda, Takuya Nakayama
