New platforms such as smartphones phablets and tablets, combined with attractive and innovative applications and

Several studies are available on the subject and many websites from association, governmental organization, regulation or standard bodies provides valuable information. http:/www.e-accessibilitytoolkit.org/toolkit/international_cooperation/international_standards_dev
19、elopment The present document intends to gather some concrete requirements and make proposals for communication tools/devices/Services/interfaces, for vision impaired people (blind, or low vision, or partially sighted people). Blindness is defined by the World Health Organization (WHO) as vision in
20、a persons best eye of less than 20/500 or a visual field of less than 10 degrees. (According to numbers from the WHO, 90% of blind people live in the developing world). Low vision generally refers to a severe visual impairment, not necessarily limited to distance vision. Low vision applies to all in
21、dividuals with sight who are unable to read the newspaper at a normal viewing distance, even with the aid of eyeglasses or contact lenses. Partially sighted indicates some type of visual problem. According to WHO, 285 million people are estimated to be visually impaired worldwide: 39 million are bli
22、nd and 246 have low vision. 65 % of all people who are visually impaired are aged 50 and older, while this age group comprises about 20 % of the worlds population. With an increasing elderly population in many countries, more people will be at risk of age-related visual impairment. Vision impaired p
23、eople face sometimes insurmountable difficulties when they want to access new technologies using a computer, Internet access, editing and printing a text, reading a document can be extremely complex tasks despite their simplicity to another user, but ICT may today give people with vision disabilitie
24、s capabilities to improve their social and economic integration in their society if some specific requirements are taken into consideration when product and services are designed. ETSI ETSI TR 103 185 V1.1.1 (2015-08) 5 1 Scope The present document aims at identifying use cases for vision impaired p
25、eople for e-access to ICT products and services but also use cases to allow users to interact with machines or equipment (e.g. users terminal, user interface) via dedicated devices (M2M communications) in order to define appropriate protocols (NFC or similar). The intention is not to define technica
26、l solutions but to forward the requirements to the appropriate ETSI Technical bodies. Equal access to services, to WEB content, to public places is now required by law in many countries. Vision impaired people often use of specialized devices which can help them in the current life and also provide
27、access to entertainment (access to Television, book reader, etc.). Being able to use computers, mobile phones and other tools for, work, leisure and keeping in contact are key tools for blind and partially sighted people. In the present document, some requirements and/or proposals in possible assist
28、ive technology for the vision impaired people are listed. The present document is devided in 3 sections: Section 1 where accessibility requirements have already been studied and proposed solutions identified. However, these requirement are often ignored. This is the case for web and content document
29、 accessibility. Section 2 where accessibility requirements exist are partially considered, however this report bring some new considerations and propose recommendations. This is the case for terminals smartphone, phablets, and tablets. Section 3 where accessibility requirements are not yet really co
30、nsidered, because several type of requirement may be requested. This is the case for e-purchasing, Kiosks, Television, M2M, etc. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
