CHARACTER INPUT PREDICTION APPARATUS, CHARACTER INPUT PREDICTION METHOD, AND CHARACTER INPUT SYSTEM
First Claim
1. A character input prediction apparatus comprising:
- a first operation input unit configured to obtain information of a first character input operation that is performed by a user using a character key layout display in which a plurality of character keys are arranged;
a dictionary storage unit configured to store a dictionary including a plurality of candidate character strings;
a character key layout management unit configured to store a character key layout showing the arrangement of the plurality of character keys in the character key layout display;
a first indication movement detection unit configured to detect a first indication position and a first indication direction in the character key layout display from the information of the first character input operation, the first indication position showing a position of the first character input operation, and the first indication direction showing a movement direction of the first character input operation;
a first filter generation unit configured to determine a first character range in the character key layout display using the first indication position, the first indication direction, and the character key layout, the first character range being located in the first indication direction with the first indication position as a base point; and
a dictionary search unit configured to search the plurality of candidate character strings included in the dictionary, for a predictive character string that includes any character included in the first character range.

Abstract
A character input prediction apparatus includes: an operation input unit that obtains information of a character input operation by a user using a character key layout display which includes character keys; a dictionary storage unit that stores a dictionary including candidate character strings; an indication movement detection unit that detects an indication position and an indication direction respectively showing a position and a movement direction of the character input operation in the character key layout display, from the information of the character input operation; a filter generation unit that determines a character range located in the indication direction with the indication position as a base point, in the character key layout display; and a dictionary search unit that searches the dictionary for a predictive character string including any character included in the character range.
