## Abstract

Provided is a braille teaching material, and a method of manufacturing the same. More particularly, the present disclosure relates to a braille teaching material, and a method of manufacturing the same, wherein a teaching tool is detachably attached to a dot corresponding to a raised dot of braille among vertical dots and horizontal dots of braille, so that even braille beginners with undeveloped fingertip sensitivity are able to learn braille.

## Claims

### Claim 1

A braille teaching material comprising:
an information section (100) showing learning information, not braille, to be used for learning, in a preset learning area;
a braille section (200) showing dots (210) corresponding to vertical dots and horizontal dots of braille in a preset braille area; and
a teaching tool (300) seated or detachably attached to the dot (210).

### Claim 2 (depends on 1)

The braille teaching material of claim 1, wherein the information section (100) shows the information provided in an uneven shape.

### Claim 3 (depends on 2)

The braille teaching material of claim 2, wherein when the information to be used for learning is a letter, the information section (100) comprises a stroke part (110) indicating a direction in which each stroke of the letter is written.

### Claim 4 (depends on 2)

The braille teaching material of claim 2, wherein when the information to be used for learning is a letter, the information section (100) comprises a start part (120) indicating a point at which each stroke of the letter starts.

### Claim 5 (depends on 4)

The braille teaching material of claim 4, further comprising:
a stroke order guidance section (400) in a preset area of opened pages of the braille teaching material, the stroke order guidance section (400) showing symbols that correspond to the start parts (120) and are arranged in the same order as the strokes of the letter are written.

### Claim 6 (depends on 1)

The braille teaching material of claim 1, wherein the braille section (200) shows which dot (210) corresponds to a raised dot of braille, in a visual manner, in a tactile manner, or in a visual and tactile manner.

### Claim 7 (depends on 1)

The braille teaching material of claim 1, wherein the braille section (200) comprises a velcro provided at a position of the dot (210).

### Claim 8 (depends on 1)

The braille teaching material of claim 1, further comprising:
an NFC tag (not shown) provided in a preset tag area, and storing information required for voice guiding the learning information; and
an NFC reader (not shown) outputting the learning information in a voice when recognizing the NFC tag.

### Claim 9 (depends on 1)

The braille teaching material of claim 1, wherein a sheet provided with the dots (210) is formed by stacking, in order, an outer layer (1100) in which the dots (210) are formed in a hole shape, and an inner layer (1200) with a meaning part (220) configured to be distinguishable by the sense of the hand at a position of the dot (210).

### Claim 10

A method of manufacturing the braille teaching material, the method comprising:
punching, at an outer layer punching step (S10), the dots (210) or the dots (210) and the learning information of the information section (100) in the outer layer (1100); and
manufacturing, at a sheet manufacturing step (S20), the sheet provided with the dots (210) by stacking the outer layer (1100) and the inner layer (1200) or by stacking the outer layer (1100), the inner layer (1200), and the outer layer (1100) in order and bonding the layers.

### Claim 11 (depends on 10)

The method of manufacturing the braille teaching material of claim 10, wherein the sheet provided with the dots (210) is manufactured by using an adhesive sheet.
