Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data input system for inputting a file name with a pen and a tablet.

[0002]

2. Description of the Related Art A tablet or digitizer for detecting the coordinates of a specified point within a screen and inputting it to a computer is used for specifying the position of the coordinate and drawing.

Among these, a data input device using a pen (stylus) and a tablet has been attracting attention as a system having both functions of a keyboard which is a data input device and a mouse which is an operation instruction (pointing) device.

As one of the usage methods, when saving data (including a program) created on a computer, a user can save the data as shown in FIG. 4 so that the user can predict the content of the data later. There is a method of inputting with a pen to give a name (file name) to the file management table corresponding to one-to-one.

A data (file) name can be input using a keyboard in a system having a keyboard, but in a pen input system, it is input using a pen. In this pen input, since the name needs to be recorded in the system as a character code, a means for converting the pen input which becomes an on / off signal into a character code is required.

There are the following two conventional methods that can be used as this means.

(1) An alphanumeric character as shown in FIG. 5 is displayed on the display device, and a character having a desired name is designated one by one with a pen.

(2) A character written with a pen is input in the same manner as handwritten character recognition, and a name is obtained by character recognition.

[0009]

In the conventional method (1), it is necessary to pick up characters one by one, which is a very troublesome pen operation. In addition, when inputting Kanji, etc., it is necessary to enter Hiragana once with the pen and convert it into Kanji, making the operation of the pen even more troublesome, and preparing software or a dictionary for Kana-Kanji conversion on the computer. There is.

In the conventional method (2), the pen operation is simpler than that of the former method, but its usability depends on the recognition rate and recognition speed of handwritten characters. Further, similar to the method (1), software for character recognition and a dictionary are required.

An object of the present invention is to provide a data input method that allows free and quick input of a name to save and name saved data, and does not require software such as kana-kanji conversion or a dictionary. It is in.

[0012]

In order to solve the above problems, the present invention provides a data input device for inputting the name of data stored in a computer with a pen and a tablet,
A first data file for storing and reading the image data of the name input by the pen and the tablet as it is, and a first data file for storing and reading the data corresponding to the name input by the pen and the tablet. Two
Of the data file, a name / data management table for registering the name and the file name of the data item and the name item uniquely assigned to the data, and the data positions saved in the first and second data files. A file management table which is registered in association with the file name of the name / data management table, and the data name is stored in the first data file as the image data input with the pen and the tablet. It is characterized in that the image data is read out and displayed as it is from the first data file and the corresponding data is output according to the selection.

[0013]

[Function] The user handwrites the name of the data with a pen and a tablet, and the image data is directly associated with the data by handwriting image data without character encoding such as character recognition, and the user saves it. To extract the data, obtain the data corresponding to the selected name from the display of the name by the handwritten image. Correspondence between this handwritten image and data is performed using the name / data management table and the file management table.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 is a block diagram of an apparatus showing an embodiment of the present invention. The computer 1 is connected with a data input / output interface between the pen 2 and the tablet 3, and inputs handwritten image data with the pen 2.

The computer 1 is also connected to the data file 4 for storing the file name data and the data file 5 for storing the user data, and inputs / outputs the file name and the user data.

The computer 1 is provided with a name / data management table 1A for storing created data in the data files 4 and 5, and a file management table 1B.

The name / data management table 1A is a name item for individually registering a file name containing data of a name input by handwritten image data by the pen 2 and the tablet 3, and the data of the target user. It is an array with the data items that individually register the file names of the files containing and as elements. These file names are automatically created and managed in the computer 1, and are invisible to the user. In the figure, for example, filei1 and file01 correspond to each other.

The file management table 1B is composed of a file name item for individually registering the file name created in the name / data management table 1A and a data position item for registering data position information etc. in which the file is stored. It is arranged into For example, the file name filei1 has the location stored in the data file 4 registered as XXXXXX, and the data file file01 having the file name file1 has the location stored in the data file 5 registered as ΔΔΔΔ. It

The data processing procedure in this embodiment will be described below.

(1) Saving of user data (1-1) The user uses the pen 2 and the tablet 3 to manually input the name of the data to be saved. The data of this handwritten image is saved as an image in the data file 4. At the time of saving this data, the computer 1 gives a unique file name and registers this in the name item of the name / data management table 1A. Also, the data such as the data storage position is registered in the file management table 1B together with the file name.
