Touch screen-oriented magnetic traction type blind person reading device and reading method thereof

Abstract

The invention discloses a magnetic traction type blind person reading device facing a touch screen and a reading method thereof. The reading device comprises a device table and a fingerstall. The device table comprises a base, a touch screen, a direct current motor, a solenoid, a mechanical arm and a control circuit. The fingerstall comprises a strong magnet, a fixing support, a braille module, a control module, a Bluetooth module and a power module. The direct current motor drives the solenoid to move in the whole area below the touch screen by controlling the mechanical arm. During use, a blind person puts a finger in a finger hole formed by the fixing support, and the probe array in the braille module can present braille information to a finger pulp. The solenoid is electrified to generate attraction force to the strong magnet, and when the solenoid moves, the finger is pulled to move to any position on the touch screen. The blind can be helped to read according to the character typesetting sequence of the virtual page, the problem that the blind cannot accurately position on a touch screen is solved, and the learning approach of the blind is expanded.

Description

technical field [0001] The invention relates to a reading device for the blind, and more specifically, to a touch-screen-oriented magnetic traction reading device for the blind and a reading method thereof. Background technique [0002] Traditionally, blind people mainly understand information such as images and text through paper materials, such as Braille books for blind people. In the case of vision loss, if only by reading Braille books, the blind person can understand very little information compared to the normal person. Braille books are made from Braille boards, Braille machines, and Braille printers by printing raised Braille dots on books. Normally, each square of Braille consists of six dots, and blind people perceive Braille by touching the raised dots. However, at present, Braille books are facing problems such as high cost, serious waste of paper, and single function and use. [0003] Today, the application of touch screen technology is very common, and norm...

Problems solved by technology

[0004] Aiming at the problem that the blind cannot obtain digital information such as images and characters on ordinary touch screen devices, the present invention provides a touch screen-oriented magnetic traction reading device for the blind and a reading method thereof. The magnetic traction device is used to guide the blind to correctly follow the The text typesetting sequence of the virtual page is used for text reading, which solves the problem that blind people cannot accurately locate on the touch screen, and provides a convenient and practical way for blind people to read
