Embodiment Construction

[0025] A tactile reproduction device applied to Braille reading, comprising:

[0026] The main control unit is used to convert common characters such as words, numbers, and letters into a specific 6-point Braille format, and send instruction signals to the tactile excitation unit in combination with the position of the finger touching the image;

[0027] The tactile excitation unit is configured to receive an instruction signal from the main control unit, generate a corresponding excitation signal, and perform high-voltage amplification to excite the tactile display panel;

[0028] The braille display unit uses an infrared positioning device to locate the touch position of the finger, and acts on the finger through the tactile display panel to make the user feel tactile.

[0029] The main control unit of the present invention is used to convert commonly used characters such as words, numbers, letters, etc. into a specific 6-dot Braille style format, which is divided into a bli...

Abstract

The invention relates to a touch representation device and method for braille reading and belongs to the field of machine and man interaction. The device comprises a main control unit, a touch exciting unit and a braille display unit; the main control unit is used for converting texts, numbers characters and the like into a specific 6-point system braille literary form, fusing finger touch position information and sending a command signal to the touch exciting unit; the touch exciting unit is used for receiving the command signal of the main control unit and generating a high pressure exciting signal waveform; the braille display unit is used for positioning the finger touch position and generating a touch action for a finger according to a touch display panel. The common characters of tests, numbers and characters are converted to the specific 6-poitn system literary form, an electrostatic touch representation technology is adopted, the blind can effectively sense the braille signs by changing the friction of the finger touching the panel, and the reading efficiency of the blind is enhanced.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a tactile reproduction device and method applied to Braille reading. Background technique [0002] 80% of the information people get comes from vision. As a disadvantaged group in society, blind people have great obstacles in receiving information because of impaired vision. Despite the rapid development of science and technology today, they still use traditional braille boards and braille machines , Braille printers, etc. make different combinations of bumps on paper to write and recognize Braille. The production process is complicated and the amount of information is limited. With the development of computer technology, pattern recognition technology and tactile reproduction technology, how to make blind people Using electronic products like normal people and improving the efficiency of information obtained by blind people has become a hot research topic. [0003] In ...
