NEW USES FOR

COMPUTERS

Sports researchers are using computers to help all kinds of athletes improve their performance. At the Coto Research Center in California, swimmers, runners, divers and other sports champions all come for help. It all starts when trained technicians make a movie of a particular athlete in action. Then they play the film in super slow motion on a special screen. The screen is divided into thousands of numbered squares. Using a special wand, the technicians touch every square. That gives the computer information about how an athlete moves.

The computer matches parts of the person’s body with the numbered squares, then it stores this information. Later an athlete, with the help of a technician, asks the computer specific questions about how he or she is performing. Using all the information it has collected, plus some basic rules about gravity, strength and force, the sports computer comes up with the answers.

The computer also lets athletes see what they’re doing wrong. It can make a true-to-life picture of the player appear on a TV screen. This lets an athlete see mistakes that he would miss in real life. And once the athlete spots the mistakes, it becomes easier to start practicing new and better ways of performing.

Of course, a computer can’t turn just any person

into an Olympic champion. But it can help talented people perform better. Before Al Oertei came to the Coto Research Center, his farthest discus throw in competition was 212 feet (64 m). But with the help of computers, other new training techniques and hard work, he threw it nine feet (2.7 m) farther than ever before!

Music Computer

A 12-foot-tall copper cone slides out on s+

stage. It is surrounded by bright lights and smoke. Moments later, sounds from an entire orchestra fill the room. The audience hears trumpets, harps, violins and drums. But no one is in sight. Then the cone’s top comes down. Inside is the Iceberg Machine-and its inventor, Michael Iceberg.

Michael is sitting in the middle of this most unusual musical instrument. He is surrounded by three computers, six keyboards and dozens of buttons. This machine produces all kinds of musical sounds plus an assortment of whirs and bleeps. There are even knobs Michael can press to get animal sounds, chines and human voices.

The Iceberg Machine contains three computers. Two control the synthesizers (SIN-thi-sizers). They are modern musical instruments that can stretch or bend notes to make unusual sounding music. The third computer is in charge of the drums.

Michael says it took him 13 years to make his Iceberg Machine. He began with 16 different musical instruments. Michael played each of these instruments himself. Then lie taped their sounds

and stored each note separately in the machine’s computer files.

The computers help Michael to play every instrument in his orchestra and to serve as the conductor, too. He can play everything from class: cal music to rock ‘n’ roll. By putting notes together in different ways, he produces millions of different sounds. He has to decide which instruments ti use, when to use them and how to blend all the sounds together. He’ll take a note from the violin, then a note from the flute and add a note from the drums. The result is music to your ears!

Zoo Computer

You know that zoos are fun places to visit. But they have a serious purpose, too. Zoos can help to protect animals, especially those kinds which are in danger of dying off. One zoo that is very active in saving endangered animals is the Minnesota Zoo, near Minneapolis. There, a special computer called ISIS keeps track of 90,000 animals from 15C different zoos in North America and Europe.

The Minnesota Zoo is particularly concerned

Computers are everywhere. Even computers that you never see are often helping you in some way. They now create some of the exciting images you see on a movie screen. Other computers guide the large roller coasters you love at amusement parks.

Computers are very useful machines. They store a huge amount of information and recall it quickly. That saves valuable time. Computers are handy for another reason. Thev store information so that it can be kept and used forever. And, when you consider how much information they hold, they hardly take up any room at all.

No doubt about it, computers help people a lot. Some help doctors find out what causes people to get sick. Others simulate or copy the experience of flying a plane so future pilots can get trained. Want to know more about new uses for computers?

Sports Computer

Al Oerter is an Olympic champion. His specialty is throwing the discus. In four straight Olympics he hurled this heavy metal disk far enough to win the gold medal. Al hopes to compete in future Olympics, too. With this in mind he went to a sports computer for help.
