Embodiment Construction

[0044] A braille tactile reproduction device based on multiple tactile feedback methods, comprising:

[0045] (1) positioning unit 10, comprising a device with a positioning function, used for positioning and obtaining the positional information of the finger, and sending this information to the processing unit;

[0046] (2) processing unit 11, including various multimedia terminals, for outputting visual information, and simultaneously performing tactile rendering on the image at the finger position, and sending the obtained tactile feedback driving signal parameters to the signal loading device;

[0047] (3) The signal loading device 12 generates a corresponding driving signal according to the driving tactile feedback signal parameters, and uses the signal to drive the interactive unit;

[0048] (4) The interaction unit 13 can change the tangential force and the normal force received by the finger, so that the finger can perceive multiple tactile force effects.

Abstract

The invention relates to a Braille haptic reproduction device and method based on a multi-element haptic feedback mode, belonging to the field of human-computer interaction. Tactile feedback includesvibration, electrostatic force and air pressure film effect, which can change the normal force in one direction and the tangential force in two directions. The device comprises a positioning unit, a processing unit, a signal loading device and an interaction unit. The positioning unit is used for acquiring the finger position information and sending it to the processing unit. The processing unit obtains the parameters of the driving haptic feedback signal according to the received position information and sends the parameters to the signal loading device. The signal loading device generates acorresponding driving signal and drives the interactive unit at the same time. The interaction unit can change the tangential force and normal force of the finger and make the finger perceive the multi-tactile force. The device adopts the multi-tactile feedback mode, and can effectively improve the efficiency and accuracy of blind reading by changing different tactile forces received by fingers toreproduce specific six-point system Braille.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a braille tactile reproduction device and method based on multiple tactile feedback methods. Background technique [0002] Blind people cannot observe the surrounding things through vision like normal people, and mainly rely on the hearing of the ears and the touch of the skin to obtain external information. For a long time, the paper version of Braille composed of different combinations of raised dots on paper through Braille boards, Braille machines, Braille printers, etc. has been used for learning by the blind. However, the number of books for Braille is small, the variety is single, the volume is large and Bulky, not only difficult for the blind to obtain, but also very inconvenient to use, which greatly limits the improvement of the overall cultural level of the blind group. [0003] Tactile reproduction technology is a research hotspot in the field of human-compu...
