Embodiment 1

[0044] Such as figure 1 and figure 2 As shown, the outdoor guide service system for visually impaired people includes handheld mobile terminals, mobile communication systems, mobile positioning systems (GPS, CORS), blind obstacle detection equipment and walking sticks, and urban GIS data application servers.

[0045] Handheld mobile terminal: use special voice interaction equipment for the blind, such as a special PDA for the blind, such as a special mobile phone for the blind.

[0046] Blind obstacle detection equipment and cane: including special blind obstacle detection radar and blind cane, to realize the detection and identification of the user's surrounding environment.

[0047] Mobile communication system: including GSM or CDMA or GPR wireless communication system and mobile communication server, which is the link between mobile terminal and urban GIS database server; it is used to transmit the environmental information and personal needs of users during travel to the...

Embodiment 2

[0057] Based on the above system, the method of urban outdoor blind guide serving users' travel path planning is as follows:

[0058] Before traveling, the user submits a travel request to the mobile positioning server, and the mobile positioning server sends the starting point and destination to the GIS data server. The process of this service method is as follows: Figure 6 . The specific steps are as follows:

[0059] 1. Start the client software;

[0060] 2. The mobile terminal obtains the current location through the mobile positioning system, obtains the multimedia data of the location according to the location information, and provides it to the user in the form of voice at any time;

[0061] 3. Obstacle detection radar and cane will return the collected obstacles and environmental information around the user's location to the server through the mobile communication network; after the server confirms the information, it will send a message to the user in the form of v...

Embodiment 3

[0067] Based on the above system, the method of urban outdoor blind guide serving real-time fine guide is as follows:

[0068] During the travel process, the user submits a service request to the GIS data server according to the location and the surrounding information. The service process is as follows: Figure 7 . The specific steps are as follows:

[0069] 1. Start the client software;

[0070] 2. The mobile terminal obtains the current location through the mobile positioning system, obtains the multimedia data of the location according to the location information, and provides it to the user in the form of voice at any time.

[0071] 3. The obstacles and environmental information collected by the obstacle detection radar and cane will be returned to the city GIS data server through the mobile communication network. After the city GIS data server confirms the information, it will send a message to the user in the form of voice.

[0072] 4. The client software interacts w...

Abstract

The invention discloses an outdoor blind guiding service system oriented to paropsia people, which comprises a hand-hold movable termination, a mobile communication system, a mobile location system (GPS, CORS), blind-used obstacle detecting equipment and a cane, urban GIS data application server etc. The hand-hold movable termination makes use of voice recognition to realize the speech interaction with users, which also obtains the information of users and surrounding environment through mobile locating system and blind-used radar and makes use of the mobile communication system to correlate with the urban GIS data application server so as to provide the paropsia people with real-time voice guidance service of moving route. At the same time, the invention also discloses a method to provide outdoor blind guiding service for paropsia people with the system. The system makes full use of present equipment and facilities and makes improvement, so only specific hand-hold terminal is needed and the requirement of other equipment and network can be solved through existing resources.

Description

technical field [0001] The present invention relates to an urban outdoor blind guide service system and method for visually impaired people, in particular to an urban outdoor blind guide service for visually impaired people with speech recognition technology, geographic information system technology, mobile communication network technology, mobile positioning technology, and multimedia technology systems and methods. Background technique [0002] With the development of society, people's concern for the disabled in the whole society is becoming more and more common. Visually impaired people, especially the blind, encounter insurmountable obstacles in their urban life because they cannot normally obtain spatial perception through visual channels. The activity characteristics of the visually impaired determine that their trips mainly rely on walking and public transportation. The first guide service for the blind is global path planning, which formulates a complete plan for t...
