For this research project the topic I have chosen to cover is, "The impacts of assist ive technology for the blind and visually impaired". I will discuss the benefits and drawbacks to using advanced technology to promote development. I will also look at how assist ive technology is being implemented and what effects it has on the visually impaired. There are approximately 10 to 11 million blind and visually impaired people in North America, and their visual abilities vary almost as much as their ethnic, racial, and personal characteristics do. The term 'visual impairment' covers a wide range and variety of vision, from blindness and lack of usable sight; to low vision, which cannot be corrected to normal vision with standard eyeglasses or contact lenses; to moderate visual impairment and an inability to read the fine print in a daily newspaper. People who are visually impaired, like everyone else, pursue a great range of interests and careers and participate in the full range of daily activities.

They may need to receive training in various adaptive techniques in order to do so, and educational and other services and products are designed and available for this purpose. Federal and state estimates used for planning educational services do not adequately account for the number of children in the United States who are blind or visually impaired. In some cases, only students who are legally blind are reported, ignoring those who have difficulty seeing but do not qualify as 'legally' blind. In other instances, children who are visually impaired and have other disabilities such as mental retardation are not counted as visually impaired because they are reported in other federally defined categories, such as multiple disabilities.

Tragically, because many 3 professionals lack the specialized skills necessary to recognize and address vision loss, there are also children with visual and multiple impairments whose vision loss remains undiagnosed throughout their school experience. The inadequate count of visually impaired children means that our nation lacks critical information about the need for specialized services for these children, and cannot correctly allocate the specialized resources and personnel required. Consequently, many children do not receive the appropriate specialized educational services they need. Technology has revolutionized daily life for all of us, but it has had particularly dramatic benefits for people who are blind or visually impaired.

Until only recently, the world of print was largely closed off to people with little or no sight. But the power of computers has now brought this world within reach for those unable to see. Computer technology, including specialized hardware or software that simulates the human voice reading the computer screen or renders hard copy output into Braille, designed to help persons with disabilities perform daily tasks, has changed the lives of countless individuals with visual impairments. Assistive technology has exploded many barriers to education and employment for visually impaired individuals. Students with visual impairments can complete homework, do research, take tests, and read books along with their sighted classmates thanks to advances in technology.

Adults with visual impairments can continue to work and pursue a tremendous range of careers in mainstream society because of the use of computers and other devices. The most common forms of assist ive technology are the use of Braille, speech systems, screen magnifier's, and video magnifier's. Braille is a type of print that is raised 4 so that blind or visually impaired people can read by feeling the words with their fingers. There are Braille printers hat provide hard copy information from computer devices, and electronic Braille note takers that provide a powerful alternative to mechanical note takers. Another form of technology comes in speech systems. A synthetic speech system is composed of two parts: the synthesizer that does the speaking, and the screen reader that tells the synthesizer what to say.

The synthesizers used with computers are text to speech systems. Their programming includes all the phonemes and grammatical rules of a language. This allows them to pronounce words correctly. Names and compound words can cause problems, as they often contain unusual spellings and letter combinations. The last type of assist ive technology is a low tech device.

Video magnifier's use a stand mounted or handheld video camera to project a magnified image onto a video monitor, a television screen, or a computer monitor. Visual impairments change the way children obtain information about the world in which they grow and function, and limit opportunities to learn through observation of visual elements in the school curriculum and the people around them. This means that, in addition to their regular classroom studies, children who are blind or visually impaired need to learn specialized skills from teachers and others who are specially trained to teach these skills, such as certified teachers of visually impaired children and orientation and mobility specialists. The specialized skills visually impaired children must learn include: Technology and computer proficiency skills which means using computer and telecommunication equipment and software adapted for blind or visually impaired people; literacy skills of reading and writing with Braille, large print, optical devices, or 5 training in effective use of available vision; Safe and independent mobility skills which require using specific orientation and mobility techniques, long canes, or other mobility tools; Social interaction skills of understanding body language and other visual concepts; Personal management and independent living skills of learning specialized techniques for personal grooming, food preparation, money management, and other tasks. Children with visual impairments receive educational services from an array of options that includes residential and special schools specifically designed for blind and multiply disabled children, and special classes, resource rooms, and itinerant teaching services in regular education classrooms in the child's community where most visually impaired children are educated. Based upon the individual needs of children and input from their parents and educators, specialized schools, or classes are appropriate educational options for certain students.

In addition, special schools frequently provide outreach support and technical assistance to public schools in their states. Although many school programs provide the specialized instruction needed by students who are visually impaired, there is much room for improvement. Too many visually impaired students leave school without having mastered the skills or knowledge essential for further education, gainful employment, and independent living at home and in their communities. There is a severe shortage of orientation and mobility specialists and qualified teachers of visually impaired students, which restricts access to the specialized skills these children need.

This means that students with visual impairments frequently receive instruction from personnel who are not qualified to teach critical skills such as Braille, cane and other travel skills, and effective use of available vision. This 6 problem is even more alarming in rural communities, where shortages of qualified personnel are most acute. Equally detrimental is the continued perception by many that residential and special schools for blind and visually impaired children are too costly, or, because most visually impaired children are educated in regular education classrooms, unnecessary. This fallacy persists despite the fact that education experts agree that for some children, special schools are the best placement option, and that the Individuals with Disabilities Education Act passed by the U.S. Congress makes access to all educational placement options, including special schools, every child's right. As a result of my research I have found that assist ive technology is very helpful to blind or visually impaired people when used appropriately. Technology has set new standards and goals for the visually disabled and blind that were never within reach without these new break through's.

The main issues that still need to be dealt with is making sure the new technology is taught correctly to the people who need to use it, and that access to the latest technology is easily attainable.
