Embodiment Construction

[0020] A flexible and wearable action regulator based on piezoresistive sensors with a pyramidal interlocking structure, including: a text information collection unit, a signal conversion unit, a signal transmission unit, a signal processing unit, a mobile phone APP, and a button battery. The specific working principle of the invention is as follows: the sensors are arranged in a certain array and pasted under the belly of the finger. When the user is reading, the pad of the finger is pressed on the text, and then the text to be read is swept across. The bumps of the Braille will cause a small deformation of the sensor, and the small deformation of the sensor will further lead to a change in its own resistance, thereby resulting in a change in the electrical signal. The output electrical signal is transmitted to the signal conversion unit to convert it into a digital signal. The converted digital signal is matched with the database in the data processing unit. The final matc...

Abstract

The invention provides a flexible wearable reading device for the blind based on an extremely sensitive pyramid type interlocking structure. The reading device comprises a sensor unit, a signal conversion unit, a signal transmission unit, a signal processing unit and a mobile phone APP. According to the invention, by adhering the reading device to a fingertip, during reading, the fingertip is usedfor touching to-be-read blind Braille or quite deep engraved characters, a sensor generates electrical signals by sensing uneven characters and the electrical signals are converted into digital signals through the signal conversion unit. The digital signals are allowed to match preset data in a database through the signal processing unit, then, character information corresponding to the successively matching digital signals are sent to the mobile phone through the signal sending unit and the touched Braille is broadcast through the mobile phone APP. According to the invention, the reading device is light, simple in structure, portable, easy to operate, quite low in cost and easy to produce in big batch and has quite profound market prospects.

Description

technical field [0001] The present invention relates to the fields of sensors, signal processing technology, text information processing technology, wireless sensor network, Internet of Things and the like. In particular, it relates to a flexible and wearable motion regulator based on a piezoresistive sensor with a pyramidal interlocking structure, which belongs to the field of intelligent control. Background technique [0002] Blindness brings various inconveniences to the blind, and reading is one of them. To solve this problem, humans invented Braille to facilitate reading for the blind. But the use of Braille has its own limitations. First of all, learning Braille is time-consuming and labor-intensive, because before learning Braille, you must first train your ability to read. Second, the reading speed and reading accuracy of Braille are not very high for ordinary blind people. Third, due to the language version and the slow update of Braille teaching materials, ther...
