1 Scope
This standard specifies the technical requirements for the system configuration method,service provision method, service function requirements, information transmission and
processing of the internet information service assistant system for visually impaired.
This standard applies to the construction, development, test, and acceptance of Internet Information Service Assistant System for Blind Persons.
2 Terminology, Definitions and Abbreviations
2.1 Terminology and Definitions
The following terminologies and definitions apply to this standard.
2.1.1 Information Accessibility
Anyone who is healthy or disabled, young or old can benefit from information technology and has equal, accessible and accessible access to information under all circumstances.
2.1.2 CS Architecture
The Client/Server (Client/Server) software system architecture reduces the communication overhead of the system by rationalizing tasks to the Client and Server side, and it is required the client to be installed for management operations. Client and server-side programs are different, the user's program is mainly in the client, server-side mainly provides data management, data sharing, data and system maintenance and concurrent control ,etc. , and the client program mainly completes the user's specific business. Typical CS architecture software includes various network tools such as stock market software, stock order software,
anti-virus software ,and other network tools.
2.1.3 BS Architecture
The Browser/Server structure is a change or improvement to the C/S structure. In this structure, the user interface is implemented entirely through the browser.
There is no specific application program on client since they are all on the server. The upgrade and maintenance of these programs can be done on the server, which is pretty convenient. Because
the client uses a browser, the user interface is more user-friendly, but some functions are limited(e.g. printouts of data, etc.).In order to overcome this disadvantage using of the browser way to implement difficult functions, develop into published controls individually in the client use the program calls to complete.
2.1.4 Instant Messaging
Through the Internet real-time sending and receiving information technology, the early provision of online text chat services, and now that developed to support video, voice, and document transmission, integrating communication, information, entertainment, search, e-commerce, office collaboration, and corporate customer service integrated information services technology. Typical instant messaging software tools include QQ, MSN, AliTM, etc.
2.1.5 Scene Description
When the visually impaired needs to know the specific situation of a certain scene, they can temporarily capture scene photos through PC or mobile phone, and send scene photos and related scene description service requests to the system. The system describes the photos according to the service request, and feeds the description information back to the user in the form of text and voice. For example, the visually impaired can ask the manual customer service to help describe the color of the clothing they are wearing, the text information on the packaging of the goods, and so on.
2.1.6 Walking Orientation
When the visually impaired has a need for route guidance, they can initiate a request to the server and send the route guidance service request to the system. The system forwards the service request to the response end terminal. After accepting the request, the response end staff automatically connects to a video dialogue with the client terminal. Through the two-way video dialogue function, it helps the visually impaired describe the surrounding environment, topography, obstacles, etc., and guide the visually impaired to move forward.
2.1.7 User End
The client software of the Internet Information Service Auxiliary System for the visually
impaired is installed on PCs, mobile phones and other user devices to assist users to access the system and obtain verification code identification, graphic description and other types of auxiliary services.2.1.8 Response End
Assist the staff of the system manual desk to provide service software to the user, receive client-initiated requests forwarded from the server, process user requests, and feedback
service information to the client. The Response End software can be installed on the server or on PCs, mobile phones and other devices, and support the function of PC or mobile phone remote access to the system.
