Abstract

The utility model relates to a teaching tool for the blind - a learning machine for blind children, which is composed of a host and learning cards for blind and plain text graphics; the host includes a computer motherboard, storage devices, high-brightness display screens, sounders, hand Sensing area, blind plaintext display conversion key, power supply; computer motherboard includes central processing unit, data memory, keyboard, display control and data communication interface. Blind and plain text graphic learning cards can be inserted into the Braille hand sensing area of the learning machine for blind children. By using the blind and plain text graphic learning cards and voice prompts, blind children can learn characters and perceive graphics under the prompts of voice and hand sensing. ; At the same time, the high-brightness display screen can display Braille characters in plain text. It solves the problem of lack of teaching aids for blind children in the teaching of visually impaired children with words and graphics. It is especially suitable for low-grade blind children, and can also be used for low-vision children at the same time.

Description

Learning machine for blind children

Technical field:

The utility model belongs to the technical field of teaching tools for the blind.

The utility model relates to a teaching device, in particular to a text enlightenment learning machine for blind children and low-vision children.

Background technique:

The existing Braille enlightenment learning still uses traditional teaching aids and learning methods, which is not conducive to the rapid acquisition of Braille and perceptual graphic knowledge for young blind children, it is difficult to improve the teaching progress and quality, and it is not conducive to the intellectual development of blind children.

Invention content:

The purpose of the utility model is to overcome the above-mentioned defects in the existing learning teaching aids, and provide an enlightenment learning machine suitable for blind children and children with low vision to learn characters and graphics.

The technical solution of the present invention is: the learning machine for blind children is composed of a host computer and learning cards for blind and plain text pictures and texts. The host includes computer motherboard, storage device and power supply. The main board of the computer comprises a central processing unit, a data memory, a keyboard, a display control and a data communication interface; a high-brightness display screen, a hand-sensing area, a recording key, a sounder and a braille switch are arranged on the front of the mainframe.

Because the utility model is equipped with a hand-sensing area in the learning machine, blind and plain text picture-text learning cards can be inserted into the Braille hand-sensing area, and the blind and plain text picture-text learning cards are used to prompt by voice. Use your hand to sense text and graphics. At the same time, the high-brightness display screen can display Braille characters in plain text. It solves the problem of lack of introductory teaching aids for words and graphics for blind children, and is especially suitable for low-grade blind children. It can also be used in low-vision children at the same time.

The significance of the utility model lies in that a new teaching tool suitable for blind children's entry-level learning is designed. Through hand induction, voice and high-brightness display, the difficulty of learning is reduced, and diagrams, Both texts. Make the learning of Braille and graphics relatively easy, and improve the learning interest and learning quality of blind children.

After adopting the above-mentioned technical scheme, the learning machine for blind children of the present invention has strong intuition and good imitability, and can be used for totally blind children or children with low vision. And the content of the learning card can be changed arbitrarily. Learning content can be customized using the voice recording function. Greatly facilitate the user. The invention has the advantages of improving the teaching efficiency and quality and being widely used.

Detailed ways

Below in conjunction with the accompanying drawings and specific examples for further description

As shown in the figure, the utility model comprises a main frame (computer motherboard, storage device) 1 and a blind, plain text and graphic text learning card 7 that contain a control circuit; in the main frame 1, there are a hand sensing area 2, a high-brightness display screen 3, and a sounder 4. Blind plaintext switch 5, recording key 6. When in use, you only need to insert the blind and plain text picture-text learning card 7 into the hand-sensing area 2, press any position in the hand-sensing area 2 at will, and the learning machine can send out the words on the blind and plain text picture-text learning card 7 or the sound corresponding to the graphic. Blind children can touch the corresponding text or graphics in the hand-sensing area according to the prompt. Now, the low-vision young children can also use the blind plaintext conversion switch 5 to display the words in the blind and plaintext graphic learning card 7 in plaintext or braille in the high-brightness display screen 3, and the voice can also prompt simultaneously, so as to reach the goal of getting started with learning. Purpose.

The utility model has a recording function, and the user can conveniently increase learning content.
