Abstract

In an information processing apparatus having a handwriting input unit made of an integral structure of a handwriting coordinate input device and a plane display, the screen of the handwriting input unit is constituted by one or more areas, and there are provided a form defining unit for defining in advance a process operation for each area and a stroke interpretation executing unit for executing the process operation defined by the form defining unit when a handwritten stroke is inputted to the area. It becomes therefore possible to input data with a realistic sense of writing data on a paper with a pen without intercepting human thinking processes, while considerably improving man-machine interface.

Claims

1. A handwritten input information processing apparatus, including a handwriting input unit made of an integral structure of a handwriting coordinate input device and a plane display, said display having a screen having a plurality of input areas receiving handwritten input information, comprising:

a form defining unit adapted to define in advance a process operation for handwritten input information of each input area of said screen of said handwriting input unit, said screen having at least two input areas with respectively corresponding independent and different process operations, wherein the different independent process operations respectively correspond to the at least two input areas of the screen, wherein handwritten information inputted in one of said input areas is operated by a process operation corresponding to said one of said input areas, and

a process operation executing unit adapted to read said process operation that corresponds to an area into which handwritten information was inputted and to execute said read process operation, wherein said form defining unit and said process operation executing unit, respectively, include an operation description for causing a particular input area to change the process operation contents of a handwritten stroke in said particular input area, and an execution process for said operation description,

whereby changing said process operation of said processing operation unit can be performed without affecting the process operations of the other input areas.

2. A handwritten input information processing apparatus according to claim 1, wherein said form defining unit and said process operation executing unit, respectively, describe a handwriting recognition process operation for recognizing a handwritten stroke in said handwriting input unit as a predetermined code, and execute said described process operation.

3. A handwritten input information processing apparatus according to claim 1, wherein said form defining unit and said process operation executing unit derive a feature data of a handwritten stroke in said handwriting input unit, and use said feature data as the information for said process operation description.

4. A handwritten input information processing apparatus according to claim 1, wherein said form defining unit comprises a screen defining unit that defines a layout of said screen and an action defining unit describing a process operation for a handwritten stroke for each input area defined by said screen defining unit.

5. A handwritten input information processing apparatus according to claim 4, wherein an object area for the operation description by said action defining unit is derived in accordance with a screen definition data defined by said screen defining unit.

6. A handwritten input information processing apparatus according to claim 5, wherein said input area is derived as one of a closed area, a U-character-shaped rectangular area with one side of a closed rectangle being removed, and a blank character area in a character string, in accordance with line information of said screen definition data.

7. A handwritten input information processing apparatus, including a handwriting input unit made of an integral structure of a handwriting coordinate input device and a plane display, said display having a screen having a plurality of input areas receiving handwritten input information, comprising:

a form defining unit adapted to define in advance a process operation for handwritten input information of each input area of said screen of said handwriting input unit, said screen having at least two input areas with respectively corresponding independent and different process operations, wherein the different independent process operations respectively are described in the at least two input areas of the screen, wherein handwritten information inputted in one of said input areas is operated by a process operation corresponding to said one of said input areas, and

a process operation executing unit adapted to read said process operation that corresponds to an area into which handwritten information was inputted and to execute said process operation, wherein said form defining unit and said process operation executing unit, respectively include an operation description for causing a particular input area to change the process operation contents of a handwritten stroke in said particular input area and an execution process for said operation description,

whereby changing said process operation of said processing operation unit can be performed without affecting the process operations of the other input areas.

8. The handwritten input information processing apparatus according to claim 7,

wherein said form defining unit and said process operation executing unit, respectively, describe a handwriting recognition process operation for recognizing a handwritten stroke in said handwriting input unit as a predetermined code, and execute said described process operation.
