Abstract
Abstract The present invention provides an input processing system which enables input of Chinese characters by kana-kanji conversion (Japanese syllable-Chinese character) or English words, etc. promptly with easy operation. All candidates of characters for input objects are set to a predetermined order and grouped into plural hierarchies, and are stored in a dictionary where a higher hierarchy group consists of each of the top item for one level lower hierarchy. According to an input position defined by an input unit, the lower hierarchy menu is displayed which is selected in the menu item in one level upper menu. The selected character is executed as an input object by pointing the menu item in the hierarchial menu.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
158 words
An input system for characters used in a digital computer having a display unit, comprising: an input unit having two or less switches for pointing an input object on said display unit; at least one dictionary storing all candidates of character/characters for input objects, said candidates being arranged in a predetermined order and grouped into a hierarchy structure having a plurality of hierarchy groups in which an upper hierarchy group having upper level candidates each of which is a first candidate of character/characters in a hierarchy group immediately lower than said upper hierarchy groups; means for displaying a menu consisting of said candidates arranged in said plurality of said hierarchy groups in a hierarchical order from a top hierarchy group to lower hierarchy groups connected by cursor on said display unit; and means for selecting an item of said menu to decide one of said candidates of character/characters for said input object with use of said input unit.
Claim 2
Dependent Claim
158 words
An input system for characters used in a digital computer having a display unit, comprising: an input unit having two or less switches for pointing an input object on said display unit; at least one dictionary storing all candidates of character/characters for input objects, said candidates being arranged in a predetermined order and grouped into a hierarchy structure having a plurality of hierarchy groups in which an upper hierarchy group having upper level candidates each of which is a first candidate of character/characters in a hierarchy group immediately lower than said upper hierarchy groups; means for displaying a menu consisting of said candidates arranged in said plurality of said hierarchy groups in a hierarchical order from a top hierarchy group to lower hierarchy groups connected by cursor on said display unit; and means for selecting an item of said menu to decide one of said candidates of character/characters for said input object with use of said input unit.
Claim 3
Dependent Claim
56 words
An input processing system for characters according to claim 1, wherein in the case where an item of said menu where a cursor is positioned has lower hierarchy groups, said means for displaying menu automatically displays another menu of item list which consists of the first candidates of character/characters in each of said lower hierarchy groups.
Claim 4
Dependent Claim
34 words
An input processing system for characters according to claim 1, wherein said means for displaying menu closes the displayed menu when a cursor is positioned outside of a predetermined area in the display screen.
Claim 5
Dependent Claim
53 words
An input processing system for characters according to claim 1, wherein plural kinds of dictionaries are provided according to a variety of candidates for an input object of character/characters, and said input processing system having means for selecting one of said dictionaries or changing said dictionaries when receiving instructions through said input unit.
Claim 6
Dependent Claim
92 words
An input processing system for characters according to claim 1, wherein said dictionary has a certain data structure that does not depend on the kind of character/characters for input objects; said means for displaying menu is comprised of a processor to carry out displaying menu with an algorithm of program that can be accommodated with different kinds of dictionaries; and said means for selecting the item is comprised of said processor which decides character/characters for input objects by an algorithm of program that can be accommodated with different kinds of said dictionaries.
Claim 7
Dependent Claim
27 words
An input processing system for characters according to claim 1, wherein a type of data structure of said dictionary is set to one of several predetermined forms.
Claim 8
Dependent Claim
61 words
An input processing system for characters according to claim 6, wherein one of said type of data structure of said dictionary is formed with, according to each menu item which corresponds to said candidate, a set of character/characters code to be input in said processing system and a pointer directed to a group of menu items belonging to a lower hierarchy.
Claim 9
Dependent Claim
67 words
An input processing system for characters according to claim 6, wherein one of said type of data structure of said dictionary is formed with a set of display codes for displaying said character/characters as said menu item, codes to input said character/characters when one of said menu items is selected, and a pointer directed to a menu item group of the lower hierarchy of said menu item.
Claim 10
Dependent Claim
