The present document provides guidance for the user interaction design of telecommunication devices and services that are likely to become available for large-scale rollout to consumers in the next five to ten years. In particular@ the document identifies provisions that have to be made in order to ensure that forthcoming interaction technologies deployed in devices and services will be usable by all users including older people and/or people with disabilities. The present document lists user interaction technologies likely to be employed in future devices and services in the form of a technology roadmap. For each identified technology@ key characteristics specified include: ? user requirements impacted by the technology; ? benefits and accessibility barriers that will result from deployment; ? solutions related to accessibility barriers (both those benefiting disabled users only as well as those being useful for all users in different contexts). Measures are identified that need to be addressed prior to the large-scale implementation of those technologies in order to ensure their usability by users with the widest range of characteristics. Within the scope of the document are those interaction technologies that are likely to be used in information and communication products and services and are likely to achieve a mass-market breakthrough between 2010 and 2020. Interaction technologies that are exclusively used in: ? stand-alone@ off-line products and services; ? assistive devices; ? safety and security-related products and services; are not within the scope of the present document@ even though the guidelines may also apply to some of them. General user interface design issues (e.g. cognitive workload) that affect the usability and accessibility of user interfaces for eServices are also outside of the scope of the present document. The intended readers of the present document are the designers@ manufacturers and suppliers of all ICT products and services that may use new user interaction technologies in their future offerings. Researchers benefit from the present document by integrating its findings into their research at a very early stage. It is expected that the present document should be utilised in the earliest stages of the planning of a new product or eService to ensure that the measures proposed can be taken into account during all stages of the product design and implementation process. Such usage should ensure that the resulting product or eService is as barrier free in its design as possible.
