Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Human Factors (HF). I n t rod uct ion Motivated by the tren

18、d towards regulatory requirements, the European ICT industry is preparing for developing solutions for making their products usable for all users, including elderly users and those with disabilities. Where a “Design for All“ solution is not readily achievable, one-solution that may be chosen is to o

19、ffer technical interfaces to permit the use of so called assistive devices that fill the gap between the user interface of the device and the abilities of the user. Elderly and disabled users would benefit from standards for these interfaces so that one assistive device, e.g. a display for the prese

20、ntation of information in large letters, can be used for the widest possible range of products from different manufacturers. The manufacturers themselves would benefit by complying with European and international regulations if they offer a compatible interface even if they leave the production of t

21、he assistive devices to third party manufacturers. ETSI 6 ETSI TR 102 068 VI .I .3 (2002-1 1) 1 Scope The present document gives guidance on the needs of older and disabled people for assistive technology devices and the requirements for the interconnection of such devices to Information and Communi

22、cations Technologies (ICT) systems. The report considers devices for user interface input (e.g. keyboards) and output (e.g. display content) as well as speech and video transmission. It reviews available transmission technologies (e.g. Bluetooth and DECT) and requirements for transmission protocols.

23、 The present document is applicable to assistive technology devices and information and communication devices which have an interface for communicating with a user. 2 Re fe re nces For the purposes of this Technical Report (TR), the following references apply: il CENKENELEC Guide 6: “Guidelines for

At the same time there is a growing recognition of the n

42、eed to integrate older people and people with disabilities into society by enabling them to remain independent for as long as possible. Information and Communications Technologies (ICT) play an important part in this integration process. Taking the needs of this broader spectrum of people into accou

43、nt in the design process is called “Design for All“, or “Universal“ or “Barrier free“ design (terms more often used in the United States). The philosophy behind Design for All is to ensure that mainstream equipment and services can be used by a wide range of users, including older adults and people

44、with disabilities. The philosophy is best summarized in the definition of Design for All given by the ICTSB Project Team 13: “The design of products, services and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design“. Where a

45、 Design for All solution is not reasonably achievable, one possible solution is the provision of a technical interface to permit the use of a so called “assistive device“ to fill the gap between the needs of the user interface of the device and the abilities of the user. All users would benefit from

46、 standards for these interfaces so that one assistive device, e.g. a display for the presentation of information in large letters, can be used for the widest possible range of products from different manufacturers. Assistive technology is thus used to modiSl the method of inputting information to or

47、 receiving information from a piece of mainstream technology. Assistive technology is required by a user of ICT technology whenever the persons disability is such that they cannot operate the technology safely and efficiently. The increasing use of the Design for All philosophy should mean that the

48、majority of disabled people will not require assistive technology but will be able to use mainstream technology successfully. There are many factors that determine whether an individual requires mainstream or assistive technology to carry out any particular information or communication task. These f

49、actors include the nature and type of their disability as well as their access to information and to finance and their personal interest and motivation. A person may require assistive technology to carry out a particular task with an item of ICT equipment but not require it for a different task. Improvements in neonatal survival have led to a growth in the number of young people with multiple minor disabilities. The overall effects of these disabilities can be difficult to assess as they are not a simple sum of the individual minor effects . ETSI 9
