作者： Zabala, Joy Blunt, Merv Carl, Diana Davis, Sharon Deterding, Cheryl Foss, Teresa Hamman, Terry Bowser, Gayl Hartsell, Kim Korsten, Jane Marfilius, Scott McCloskey-Dale, Susan Nettleton, Sandra Reed, Penny University of Kentucky United States University of Missouri-Kansas City United States Region IV Education Service Center United States Region III Education Service Center United States University of Kansas Medical Center United States Shawnee Mission Schools United States Intelligent Peripherals Inc United States Oregon Technology Access Program United States Georgia Assistive Technology Project United States Responsive Centers Inc United States Milwaukee Public Schools United States Eastern Instructional Support Center Germany Albuquerque Public Schools United States Wisconsin Assistive Technology Initiative United States

The consideration of assistive technology devices and services is required during the development of every Individualized Educational program (IEP) according to the Individuals with Disabilities Act, Amendments of 1997 (IDEA'97). Assistive technology devices and services, which the IEP team determines are required by a student in order to benefit from a free appropriate public education (FAPE), must be written into the IEP. Despite this requirement, mere has been no agreed upon description of high quality assistive technology services. This article describes the activities of a national group of assistive technology professionals known as the Quality Indicators for Assistive technology Services (QIAT) Consortium. The QIAT Consortium was formed to initiate a nationwide dialogue regarding quality indicators for a variety of assistive technology service areas. The work of the Consortium to date is discussed and the current set of indicators is included. Processes used in the development of the indicators are described. Implications for future use of the indicators and future development activities are discussed. © 2000 technology and Media Division of the Council for Exceptional Children.

Next frontier in accessible traveler information systems: World Wide Web-based information systems

引用

Transportation Research Record 1999年第1671期1671卷 1-4页

作者： Hunter-Zaworski, Katharine Stewart, Ronald Dept. Civ. Constr. Environ. Eng. Oregon State University Corvallis OR 97331 United States Technology Access Program Oregon State University Corvallis OR 97331 United States

Ergonomic guidelines for traveler information systems were developed as one part of an effort to ensure that new technologies associated with Intelligent Transportation Systems are available to all persons, and especially to persons with sensory, cognitive, and mobility impairments. The importance of ensuring that World Wide Web-based traveler information systems are accessible is highlighted. The ergonomic guidelines are based on research and empirical evidence from Europe and North America and are primarily concerned with static, dynamic, and tactile signs or signage systems that are used in passenger transport facilities. Many sections of the guidelines have broader applications to other information systems that involve the person-machine interface. The ergonomic guidelines are in the process of being converted to an accessible format that will be available on the technology access program website at Oregon State University. The development of ergonomic guidelines for passenger information systems has been under way for a number of years in Europe and North America. The source documents from these areas are integrated, and commentary or discussion is provided where there are significant differences of opinion or discrepancies in operating practices. The guidelines have been developed for use both by transportation and by design professionals involved with the specification, procurement, and implementation of basic or sophisticated information systems. Design standards need to recognize the variability and the associated needs of all persons. The underlying principle of `design for all' is the basis for the ergonomic guidelines.

In this paper, the performance of a new movable boundary accessing (MBA) technique for future integrated services multibeam satellite systems is studied. The multiservice environment considered includes both asynchronous and isochronous traffic consisting of video, voice, file transfer and interactive data. The movable boundary access technique proposed here will maximize the utilization of the up-link frame capacity. It is shown that the potential user population is substantially increased with the use of a moving boundary policy with minimal overhead.

There is a very large demand for basic telephone service in developing nations, and remote parts of industrialized nations, which cannot be met by conventional wireline and cellular systems. This is the world's largest unserved market. We describe a system which uses recent advances in active phased arrays, fast-packet switching technology, adaptive routeing, and light spacecraft technology, in part based on the work of the Jet Propulsion Laboratory and on recently-declassified work done on the Strategic Defense Initiative, to make it possible to address this market with a global telephone network based on a large low-Earth-orbit constellation of identical satellites. A telephone utility can use such a network to provide the same modern basic and enhanced telephone services offered by telephone utilities in the urban centres of fully-industrialized nations. Economies of scale permit capital and operating costs per subscriber low enough to provide a service to all subscribers, regardless of location, at prices comparable to the same services in urban areas of industrialized nations, while generating operating profits great enough to attract the capital needed for its construction. The bandwidth needed to support the capacity needed to gain these economies of scale requires that the system use K(alpha)-band frequencies. This choice of frequencies places unusual constraints on the network design, and in particular forces the use of a large number of satellites. Global demand for basic and enhanced telephone service is great enough to support at least three networks of the size described herein. The volume of advanced components, and services such as launch services, required to construct and replace these networks is sufficient to propel certain industries to market leadership positions in the early 21st Century.

In this paper, we study the performance of a prioritized on-board baseband switch in conjunction with a multibeam satellite handling integrated services. The services considered for the analysis include voice, video, file transfer and interactive data. The prioritized switch uses both input and output buffering, switch speed-up as well as a two-phase head-of-line resolution algorithm, in order to reduce the buffer loss while maintaining acceptable user delays. The minimum required buffer capacity and switch speed-up for each service in a prioritized environment are found under uniform traffic conditions. It is shown that under uniform traffic conditions, only minimal buffering and switch speed-up are needed even for the lowest priority users. The performance dependence on the switch size is also substantially reduced with head of line resolution and buffering even in a prioritized environment.

The role of satellite communications in networks that provide new services, such as frame relay and multimedia, is investigated. Both passive and active (on-board switching/processing) satellite systems are considered. Novel techniques are developed for each system to demonstrate, via detailed analysis and simulation, how the communications bandwidth agility of multipoint/broadcast satellite channels, and the on-board switching/processing, makes it feasible to provide these new services via hybrid satellite and terrestrial networks in a resource-efficient manner.
