Abstract

An interactive keyboard and display apparatus is used to enter ideographic characters in a computer or other utilisation device. The characters are defined by manually selecting displayed symbols such as phonemes, strokes, radicals and inflective tones represented in displayed key cells which are arranged in a matrix for rapid selection. Simultaneous multiple key cell selection is possible for accelerated character entry. The keyboard and display are integrated in a format suitable for replacing conventional keyboards. To avoid spurious entries, a pre-determined amount of pressure must be applied to the display panel when entering a symbol or character.

Claims

1. An integrated keyboard and display apparatus for selecting ideographic characters of written language, said apparatus comprising:

display means for producing an image comprising;

a first group of manually selectable key cells each of which represents and displays a selectable phonetic symbol of spoken said language, for manual selection of said symbol displayed therein,

a second group of manually selectable key cells each of which represents and displays a selectable symbol representative of a primary construction element of each of said ideographic characters of said written language, for manual selection of said symbol displayed therein, a third group of manually selectable key cells each of which represents and displays a selectable symbol representative of a conceptual element common to a plurality of said ideographic characters of said written language,

sensing means responsive to a selection of a said selectable symbol,

data processing means cooperating with said display means and responsive to a plurality of said manual selections of said selectable symbols displayed in said key cells, wherein ideographic characters unrelated to previoulsy selected said selectable symbols are eliminated from a set of candidate ideographic characters upon each said selection of a selectable said key cell, whereby said plurality of said selections of said selectable symbols ultimately defines a desired said ideographic character, and

means for transmitting a signal indicative of said desired ideographic character to utillisation means.

2. The apparatus of claim 1 further comprising:

a fourth group of adjacent and manually selectable key cells pertaining to selectable said ideographic characters, for manual selection of a desired said ideographic character displayed therein.

3. The apparatus of claim 1 wherein said sensing means are responsive to an effectively simultaneous manual selection of a plurality of displayed elements of a said image, for reducing a time period required to find and select a desired ideographic character.

4. The apparatus of claim 1 wherein said data processing means further comprise means responsive to a signal indicative of an acknowledgement of reception by said utilisation means of said signal indicative of said desired ideographic character.

5. The apparatus of claim 1 wherein said sensing means are touch-sensitive, and wherein said means for transmitting said signal indicative of said desired ideographic character is actuated by further applying a pre-determined amount of pressure on a selected said key cell representative of said desired ideographic character.
