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 information—newspapers, books, signs, menus—was largely closed off to people with vision loss. the power of computers has now brought this world within reach for those who are blind or who have low vision. 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 or adaptive technology, as it is called, 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. A variety of information on technology can be found.

Look around, though. Look at the adverts for smartphones and data plans that spring up on every web page you visit. Look at the coverage of media tablets just that you find on every technology website that has any sort of consumer readership – and even some that don't, because media tablets are finding their way into peoples' homes and businesses, just as the first PCs did almost 30 years ago.
The overall growth in PC sales will be cut dramatically over the next two years as people in the US and Europe choose tablets such as Apple's iPad 2 rather than buying laptops.The slowdown marks a new trend in which PCs limitations are being exposed. the company said, because they do not offer the portability or battery life that smartphones – which have already begun outselling PCs – and now tablets offer.
