Abstract

A portable pen pointing device and a processing system with pen pointing device which can be easily used. The portable pen pointing device includes a memory for storing user'"'"'s specific penmanship/handwriting information and a pen interface unit for supplying the user'"'"'s specific penmanship/handwriting information to a processor body of the processing system. The processor body interprets a writing sample on the basis of the user'"'"'s specific penmanship/handwriting information supplied from the portable pen pointing device through the pen interface unit thereof. With this construction, there is no need to read information from a storage medium such as a flexible disk in which a user'"'"'s specific dictionary for penmanship/handwriting interpretation is written. Also, an operation of establishing a certain writing environment becomes unnecessary or easy.

Claims

1. A portable pen pointing device in the form of a portable pen and which is handled like a pen to input information to a separate processor body, the portable pen pointing device comprising:

memory means for storing user-specific information,

wherein said user-specific information includes the user'"'"'s signature for identifying the user, user-specific penmanship/handwriting information for interpreting the user'"'"'s penmanship/handwriting when the user inputs a writing sample to said processor body using said portable pen pointing device, and a user-specific personal identification code; and

pen interface means for supplying said user-specific information to a corresponding processor interface on said separate processor body.

2. A portable pen pointing device according to claim 1, wherein said user-specific penmanship/handwriting information includes at least one of trace information for interpreting tracing of strokes in the penmanship/handwriting, writing order information for interpreting a stroke-writing order in the penmanship/handwriting, writing pressure information for interpreting a writing pressure in the penmanship/handwriting and speed information for interpreting a speed in the penmanship/handwriting.

3. A processing system with pen pointing device and a separate processor, comprising:

a portable pen pointing device in the form of a portable pen and which is handled like a pen to input information to a separate processor body, the portable pen pointing device including therein;

memory means for storing user-specific information corresponding to user-specific penmanship/handwriting information for interpreting penmanship/handwriting in consideration of the user'"'"'s specific penmanship/handwriting style, and

pen interface means for supplying the user-specific penmanship/handwriting information to said processor body, said user-specific information includes a user-specific personal identification code and the corresponding user'"'"'s signature; and

a processor, disposed within said processor body, for performing a predetermined processing in accordance with the writing sample input to said processor body, said processor including;

processor interface means for receiving at least the user-specific penmanship/handwriting information from said pen interface means of said portable pen pointing device,

means for making a judgement of whether or not said user-specific personal identification code is registered in said processor,

means for receiving input of the user'"'"'s signature,

means for receiving the user-specific penmanship/handwriting information from said processor interface means to perform a processing based on said registered penmanship/handwriting information when said user-specific personal identification code is judged to be registered in said processor, and

means for judging whether or not the input signature matches the user'"'"'s signature corresponding to said user-specific personal identification code judged to be registered in said processor.

4. A processing system with pen pointing device according to claim 3, wherein said user-specific penmanship/handwriting information includes at least one of trace information for interpreting tracing of strokes in the penmanship/handwriting, writing order information for interpreting a stroke-writing order in the penmanship/handwriting, writing pressure information for interpreting a writing pressure in the penmanship/handwriting and speed information for interpreting a speed in the penmanship/handwriting.

5. A processing system with pen pointing device according to claim 3, wherein said pen interface means of said portable pen pointing device and said processor interface means of said processor are brought into engagement with each other in a concavo-convex relationship to provide an electrical connection therebetween.

6. A processing system with pen pointing device according to claim 3, wherein said pen interface means of said portable pen pointing device and said processor interface means of said processor are connected with each other by electric wave or light in a non-contact relation.

7. A processing system with pen pointing device according to claim 3, wherein said processor further includes means for changing said user-specific penmanship/handwriting information, and the contents of change are also stored in said memory means of said portable pen pointing device.

8. A processing system with pen pointing device according to claim 3, wherein a host computer is provided, and said host computer and said processor are connected by a network.

9. A processing system with pen pointing device according to claim 3, wherein said host computer includes means for storing the user-specific penmanship/handwriting information.

10. A processing system with pen pointing device according to claim 3, wherein a writing gesture is previously stored as said penmanship/handwriting information in said memory means, and said processor further includes means for changing the penmanship/handwriting information input through said processor interface means when information input from said pen pointing device corresponds with said writing gesture stored in said memory means.

11. A processing system with pen pointing device according to claim 10, wherein a second writing gesture is previously stored as said penmanship/handwriting information in said memory means, and

said processor further includes means for storing the penmanship/handwriting information changed by said penmanship/handwriting changing means in said memory means when information input through said pen pointing device coincides with said second writing gesture stored in said memory means.

12. A processing system with pen pointing device and a separate processor, comprising:

a portable pen pointing device in the form of a portable pen and which is handled like a pen to input information to a separate processor body, the portable pen pointing device including;

memory means for storing user-specific personal identification information, including the user'"'"'s specific penmanship/handwriting information, for a user, and

pen interface means for supplying said user-specific personal identification information to said separate processor body; and

a processor for performing a predetermined processing in accordance with a user'"'"'s penmanship/handwriting input to said processor body after judging the user'"'"'s specific penmanship/handwriting information to be stored, said processor being connected by a network to a host computer which includes memory means for storing the user'"'"'s specific penmanship/handwriting information for interpreting a penmanship/handwriting sample in consideration of the user'"'"'s specific penmanship/handwriting information, said processor including;

processor interface means, disposed within said processor body, for receiving said user'"'"'s specific personal identification information from said pen interface means of said portable pen pointing device,

means for making the judgement of whether or not said user'"'"'s specific personal identification information is stored and

means for receiving, when said user'"'"'s specific personal identification information is judged to be stored, said user'"'"'s specific penmanship/handwriting information from said host computer to perform a processing based on said user'"'"'s specific penmanship/handwriting information.
