Technologies of delivery, which include almost any communication device or computer, perform the integrating function. The person with disability almost without any help has the same opportunities as the healthy person. In particular, the situation is improving with the availability of goods and services. This product can be “noticed” in the internet shop, read about it in detail to make a choice. Also the ability to distinguish the quality of services improves. For example, it is nor necessary to queue up at the station or the cash to get tickets. The person can buy them at home, and then, at a convenient time, choose the nearest non-profit fund, to show a series of numbers and pick up a ticket; on some trips no longer it is unnecessary to buy ticket, the person has to register on the site and just show a passport to the train conductor. The second example is the site of labour exchange, where the section of the vacancies for the people with disabilities is indispensable. By entering into this section, the employer clearly understands that he agreed to hire a disabled person, and disabled people have the opportunity to choose the job.
When web-site is appropriately developed and edited both healthy people and users with disabilities have the opportunity to use the Internet completely. For example, right developed html code can be adequately read by the text-to-speech program or text-to-Braille hardware. When it is possible to change the size of texts or images, people with poor sight can completely use the web-resources. When hyperlinks are underlined (or highlighted in other manner) as well as coloured, it would help color blind users. Large clickable links and areas would help people, who can’t exactly control the mouse. If video in the Web is accompanied by the sign language translation, it is available to the deaf and hard of hearing users.
Modern people already don’t feel hard binding to their desktops, and the technologies of the future, which are gradually entering into our lives, also will make portable computers or laptops unnecessary.

Availability of computer terminals with access to the global network in public places will have access to the necessary information “on the run.” Unfortunately, millions people with poor sight or blind people are denied these benefits. For the most standard actions (such as reading news, information search and receiving e-mail), these people are forced to use special software, so-called “text-to-speech”. Despite the fact that such programs became widespread, they have very serious shortage, which is the need to install applications on the hard disk. Scientists from the Washington University tried to solve this problem and developed a WebAnywhere software, which will allow blind people to access the Web sites from any available computer. In essence, the proposed instrument is the traditional “text-to-speech” software, pronouncing aloud the text showed on the display. However, unlike similar applications, WebAnywhere does not require the installation, because it is a web-service that runs in the browser window.
Some difficulties still remain during transferring the tables, but they will soon be eliminated through the use of different codes and texts. In spite of that the technical implementation of such codes is not very difficult; many web-designers simply do not recognize this need. If the developers listen to the EU, not only the elderly and people with disabilities, but everybody will benefit, as it considers representative of the Commissioner for Information Per Haugaard, tailored to the websites of these technologies more accessible to people using the “slow” internet and non-standard devices such as PDA.
Based on the technology of automated e-mail service RoboBraille can translate any text to the alphabet of blind people or make from them sound files without forcing users to access complex special programs. Established with the support of the authorities of the European Union technology is very easy to use. Anyone can just send a special e-mail text file in a recognizable system of formats – from simple text and Word documents to HTML files, and XML. Receiving the letter, service automatically starts the process of translating text into Braille or converts it to audio. The resulting document in Braille can be printed on a special Braille printer or put into tactile display – connected to the computer device with a rod, which can move forward or go down forming Braille letters. In automatic translation for blind people pharmaceutical companies, banks, insurance companies, and even the tax office are interested.
