An object of the present invention is to provide a method for confirming a text layout of a visually impaired person who obtains an audio signal corresponding to the display dot.

The present invention is a confirmation method for a visually impaired person to tactilely recognize the layout of a table created by word processor software. The table is created by the word processor software built in a computer. The data in the table is processed by text layout software built in the computer, converted into data in a format that can be displayed on the tactile display device, and further converted to the above data through control software built in the computer. Output to the tactile display device,
An object of the present invention is to provide a method for confirming a text layout of a visually impaired person, which displays the layout of the table as tactile information.

The present invention is a confirmation method for a visually impaired person to tactilely recognize a layout of a table created by word processor software. The table is created by the word processor software built in a computer. The data in the table is processed by text layout software built in the computer, converted into data in a format that can be displayed on the tactile display device, and further converted to the above data through control software built in the computer. Output to the tactile display device,
While displaying the layout of the above table as tactile information,
When the visually impaired person touches the display dot displayed on the tactile display device, the tactile display device outputs position information corresponding to the display dot touched to the control software, based on this. The control software provides a voice layout signal for a visually impaired person by outputting a voice corresponding signal to a voice synthesizing device and obtaining a voice signal corresponding to the display dot touched.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a text layout confirmation device using a text layout confirmation method according to an embodiment of the present invention.

In the figure, reference numeral 1 denotes a tactile display device, which has 9 vertical dots × 26 horizontal dots on its surface.
a is formed. The display dot 1a is driven by a drive mechanism (not shown). When the display dot 1a is selected, the display dot 1a protrudes from the surface of the tactile display device 1, and when the finger or the like is in contact with the display dot 1a. It functions to output a contact position data signal. Also,
When the display dot 1 a is not selected, the display dot 1 a does not protrude from the surface of the tactile display device 1.

Reference numeral 2 denotes one computer, and reference numeral 2a denotes word processor software / table creation software built in the computer 2, using which, for example, a person other than the visually impaired creates documents and tables. The code data corresponding to the document or table is temporarily stored in a hard disk or the like (not shown).

When the visually impaired person wants to confirm the layout of the document or the like, the text layout software 2b built in the computer 2 is started, and the code data output from the word processor software / tabulation software 2a is read. Read tactile display device 1
And outputs it as a layout signal A1 to the tactile display device 1 via control software 2c built in the computer 2,
The tactile display device 1 receives the input layout signal A1
The display is performed by driving the display dots 1a based on.

Specifically, as shown in FIGS. 2A and 2B, full-width characters are represented by two consecutively projected display dots 1a, and half-width characters are represented by one projected display dot. You. Although the ruled line of the table is represented by one continuous protruding display dot, it can be recognized differently from full-width and half-width characters by providing an appropriate space.

When the protruding display dot 1a is touched with a hand or the like, the touch information is transmitted from the tactile display device 1 to the control software 2c of the computer 2, and the position is transmitted to the position of the character in the sentence. If they match, the control software 2c outputs the voice corresponding signal B to the voice synthesizing device 3, and the touched display dot 1a
Is expressed by voice through the speaker 4.

The above operation will be described with reference to the flowchart shown in FIG. First, in step S1, a data document or table is read from the document or table data created by the word processor software / table creation software 2a using the text layout software 2b.

From the document or table read in step S2,
The text layout software 2b extracts layout data such as a ruled line and a sentence constituting a sentence or a table, and converts the sentence, the ruled line or the like into a layout signal that can be displayed on the tactile display device 1 based on the layout data.

In step S3, the layout of a sentence, a ruled line, or the like is displayed on the tactile display device 1 through the control software 2c using the layout signal A1.

In step S4, it is detected whether the tactile display device 1 outputs tactile position data in contact with the display dot 1a to the control software 2c.

In step S5, when the control software 2c receives the tactile position data signal A2 touching the display dot 1a from the tactile display device 1, the control software 2c determines whether the display dot 1a is a character or a ruled line from the tactile position data signal A2. , If it is a character, a sound corresponding signal B corresponding to the character
Is output to the voice synthesizing device 3, and the voice synthesizing device 3 outputs the voice signal C to the speaker 4 so that the visually impaired person can recognize the voice corresponding to the character.

Based on the operation shown in the above-described flowchart, the text layout confirmation apparatus for visually impaired persons of this embodiment allows the visually impaired person not only to understand sentences but also to recognize the layout of sentences. Can be.

As described above, the embodiment of the present invention has been described. However, the present invention is not limited to the embodiment shown here, and may be appropriately changed unless the structure described in the claims is changed. Can be implemented. For example, in the present embodiment, word processor software / table creation software, text layout software, and control software are incorporated in one computer, but the present invention is not limited to this, The software may be divided and installed in a plurality of computers.

[0021]

As described above, the method for confirming the text layout of a visually impaired person according to the present invention allows the visually impaired person not only to understand the text but also to recognize the arrangement of the text and the ruled lines by touch. As a result, an excellent effect can be achieved, such as the ability to more specifically recognize documents and the like created by word processor software / tabulation software.
