Problems solved by technology

Most of these blind-guiding mobile phones are based on intelligent analysis of sensors and imaging devices, and then converted into readable information. This method has a great disadvantage that it cannot effectively judge the sudden environment and drive the visually impaired. Respond correctly, which is why many guide devices cannot replace guide dogs
[0004] However, the use of guide dogs to guide the visually impaired to activities also has limitations
Since guide dogs start training with their owners shortly after birth, to get used to the owner’s password instructions and familiarize themselves with the surrounding environment, their range of activities is relatively limited. The role of blindness

no. 1 example

[0049] See figure 1 , is the flow chart of the first embodiment of the mobile terminal-based blind guiding method provided by the present invention, including:

[0050] Step S100, receiving a destination voice instruction including a destination address. For example, the destination voice command can be "Chegongmiao, Futian District, Shenzhen", "Luxiang, Hongshan District, Wuhan", or "Sunshine Golf Building", "Optics Valley Ginza", etc. In order to realize this function more accurately, a blind-guiding function key can be set on the mobile terminal, and when it is detected that the blind-guiding function key is pressed, a destination voice instruction is received through a microphone.

[0051] Step S101. Obtain a start address, and generate an optimal path according to the start address and the destination address. The mobile device is usually provided with a GPS module, and the GPS module can communicate with GPS satellites in real time to obtain the GPS signal of the curre...

[0056] See figure 2 , is the flow chart of the second embodiment of the mobile terminal-based blind guiding method provided by the present invention, including:

[0057] Step S200, judging whether there is a voice guide instruction locally stored.

[0058] If the judgment result of step S200 is no, then step S201 is executed. Step S201. Prompting the user to input a voice guide instruction, and storing it in the voice guide instruction library. Then return to step S200.

[0059] If the judgment result of step S200 is yes, then step S202 is executed. Step S202, receiving a destination voice instruction including a destination address.

[0060] Step S203, analyzing the destination address, and judging whether the destination address is stored in the map database.

[0061] If the judgment result of step S203 is no, then step S204 is executed. Step S204, prompting the user to re-input the destination voice command. Next, continue to execute step S202.

Abstract

Embodiment provided by the present invention discloses a blind guiding method based on mobile terminal and mobile terminal. The mobile terminal receives destination voice commands including the destination address; obtains the starting address and generates an optimal route based on the starting address and the destination address; obtains real-time address and generates blind guiding prompts based on the real-time address and the optimal route; searches voice guide instructions matching with the blind guiding prompts in the preset guide directive voice database, and broadcasts obtained voice guide instructions, wherein the voice guide instructions are the voice instructions prerecorded by the user and used for leading guid dogs. According to the invention, the non-efficient guiding defect of guide dogs in an unfamiliar environment is overcome, and the disadvantage of guide devices unable to cope with emergencies is avoided, which provides the convenience for daily life and work of the blind..

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a blind guiding method based on a mobile terminal and the mobile terminal. Background technique [0002] Most of the information in people's life is obtained through vision, and blind people lose their vision, which brings a lot of inconvenience to their work, life and study. Therefore, the blind person needs the assistance of a blind guide tool when walking alone. [0003] At present, there are many kinds of blind-guiding tools, and even the mobile terminals that are often used in our daily life, such as mobile phones, all have a blind-guiding function. Most of these blind-guiding mobile phones are based on intelligent analysis of sensors and imaging devices, and then converted into readable information. This method has a great disadvantage that it cannot effectively judge the sudden environment and drive the visually impaired. Respond correctly, which is why many guide dev...
