Grade 11A Name:______________________________ Class: _________________Technology:Overcoming HandicapsWhile You ReadThink about why you read. Do you know anyone with a visual or hearing impairment? As you read, look for sentences that tell about machines that people with impairments use every day.When a person cannot hear very well or is deaf, we say that he or she has a hearing impairment. New technology, or inventions, can help people with hearing problems. Technology uses science to make devices that do useful things.Many people with hearing problems wear hearing aids. A hearing aid is a smallLANGUAGE CONNECTION Speakers change soundwaves into sounds that you can understand Music you hear from the radio comes out of speakers What other things have speakers?5 device that gets power from a battery. The hearing aid turns sound waves into electrical signals. It then sends the signals to speakers that turn the waves into sounds loud enough for a hearing-impaired person to hear. Special keyboard devices allow people with hearing impairments to use the telephone. When the telephone rings, these devices display the words that the person cannot hear but10 can read. An answer can then be typed on a keyboard and sent to the caller. When the telephone rings, a light flashes.Alarms have been invented for people with hearing problems. A fire alarm or an alarm clock makes a light flash when a person is awake and makes a pillow vibrate, or shake, when he or she is asleep. An alarm can also have a loud buzzer.CONTENT CONNECTIONCaptions come to television sets as signals A decoder, a device inside the set, turns the signals into captionsHow might closed-captioning technology also help people who are not hearing impaired?15Technology lets people with hearing problems enjoy movies and television at home. With technology called closed captioning, words at the bottom of a screen, or captions, spell out what is being said. This technology allows hearing-impaired people to understand a program or a movie. Captioning shows actors' words on the screen so that someone can read them instead of hearing them.20 Technology also can help people who are visually impaired—those who are unable to see well or to see at all. We say that someone who cannot see at all is blind. A screen reader helps a blind person use a computer. The screen reader reads the screen and speaks the words in a voice that sounds human. Other computers make the words on the screen larger and easier to read.25Braille is language that helps a blind person read and write raised dots withthe fingers. The dots stand for letters and words. A Braillewriter is a machine that types in Braille. The user presses buttons that make the dots on special paper. Note takers that talk also use Braille. A person writes by pressing buttons on the keyboard. The note taker reads the words aloud or prints them in Braille.30 A new technology for visually impaired people uses signs that talk. Small machines that send out signals are placed on streets or in buildings. A person holds a device and points it in a direction to learn about that area. For example, when the device is pointed one way, it might speak the word restroom. When pointed in another direction, the device might speak the word stairs. San Francisco, in35 California, is one of the cities that has these signs at work.After You ReadA. Organizing IdeasHow does technology help people with impairments? Complete the chart below.
